  • Creating Actions from UIActionSheets help

    - by user337174
    I am using two UIAction sheets within my current project. I can get one to work perfectly fine but when i insert a second action sheet it runs the same arguements as the first. How do i define the actionsheets seperatly? -(IBAction) phoneButtonClicked:(id)sender { // open a dialog with just an OK button UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:[NSString stringWithFormat:@"Phone: %@",phone],nil]; actionSheet.actionSheetStyle = UIActionSheetStyleDefault; [actionSheet showInView:self.view]; // show from our table view (pops up in the middle of the table) [actionSheet release]; } -(IBAction) mapButtonClicked:(id)sender { // open a dialog with just an OK button UIActionSheet *mapActionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:[NSString stringWithFormat:@"Map"],nil]; mapActionSheet.actionSheetStyle = UIActionSheetStyleDefault; [mapActionSheet showInView:self.view]; // show from our table view (pops up in the middle of the table) [mapActionSheet release]; } -(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { if(buttonIndex == 0){ NSString *callPhone = [NSString stringWithFormat:@"tel:%@",phone]; NSLog(@"Calling: %@", callPhone); [[UIApplication sharedApplication] openURL:[NSURL URLWithString:callPhone]]; } }

  • Orientation issue while presenting Modal ViewController

    - by Jacky Boy
    Current scenario: Right now I am showing a UIViewController using a segue with the style Modal and presentation Sheet. This Modal gets its superview bounds change, in order to have the dimensions I want, like this: - (void)viewWillLayoutSubviews { [super viewWillLayoutSubviews]; self.view.superview.bounds = WHBoundsRect; } The only allowed orientations are UIInterfaceOrientationLandscapeLeft and UIInterfaceOrientationLandscapeRight. Since the Modal has some TextFields and the keyboard would be over the Modal itself, I am changing its center so it moves a bit to the top. The problem: What I am noticing right now, is that I am unable to work with the Y coordinate. In order for it move vertically (remember it's on landscape) I need to work with the X. The problem is that when it's UIInterfaceOrientationLandscapeLeft I need to come with a negative X. And when it's UIInterfaceOrientationLandscapeRight I need to come with a positive X. So it seems that the X/Y Coordinate System is "glued" to the top left corner while in Portrait and when an orientation occurs, it's still there: What I have done So I have something like this: UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation]; NSInteger newX = 0.0f; if (orientation == UIInterfaceOrientationLandscapeLeft) { // Logic for calculating the negative X. } else { // Logic for calculating the positive X. } It works exactly like I want, but it seems a very fragile implementation. Am I missing something? Is this the expected behaviour?

  • How should I properly format this code?

    - by ct2k7
    Hi, I've a small issue here. I am using an if statement with UIAlertView and I have two situations, both result in UIAlertViews. However, in one situation, I want to dismiss just the UIAlertView, the other, I want the UIAlertView to be dismissed and view to return to root view. This code describes is: if([serverOutput isEqualToString:@"login.true"]){ [Alert dismissWithClickedButtonIndex:0 animated:YES]; [UIApplication sharedApplication].networkActivityIndicatorVisible = NO; UIAlertView *success = [[UIAlertView alloc] initWithTitle:@"Success" message:@"The transaction was a success!" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil]; [success show]; [success release]; } else { UIAlertView *failure = [[UIAlertView alloc] initWithTitle:@"Failure" message:@"The transaction failed. Contact sales operator!" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil]; [failure show]; [failure release]; } } -(void)alertView: (UIAlertView *)success clickedButtonAtIndex: (NSInteger)buttonIndex{ switch(buttonIndex) { case 0: { [self.navigationController popToRootViewControllerAnimated:YES]; } } } So, in both cases, they follow the above action, but obviously, that's not what I want. Any ideas on what I do here?

  • Manually changing keyboard orientation for a view that's on top of a camera view

    - by XKR
    I'm basically trying to reproduce the core functionality of the "At Once" app. I have a camera view and another view with a text view on it. I add both views to the window. All is well so far. [window addSubview:imagePicker.view]; [window addSubview:textViewController.view]; I understand that the UIImagePickerController does not support autorotation, so I handle it manually by watching UIDeviceOrientationDidChangeNotifications and applying the necessary transforms to the textViewController.view. Now, the problem here is the keyboard. If I do nothing, it just stays in portrait mode. I can get it to rotate by adding the following code to the notification handler. [[UIApplication sharedApplication] setStatusBarOrientation:interfaceOrientation]; [textView resignFirstResponder]; [textView becomeFirstResponder]; However, the following simple test produces weird behavior. Start the app in portrait mode. Rotate the device 90 degrees clockwise. Rotate the device 90 degrees counterclockwise (back to the initial position). Rotate the device 90 degrees clockwise. After step 4, instead of the landscape-mode keyboard, the portrait-style keyboard is shown, skewed to fit in the landscape keyboard frame. Perhaps my approach is wrong from the start. I was wondering if anyone has been able to reliably make the keyboard change its orientation in response to setStatusBarOrientation.

  • Retaining Managed objects - more general retaining objects

    - by Luuk D. Jansen
    A quick question regarding Managed Objects. I created an Array with Managed Objects (in Object 1: TableViewConbtroller), and pass one of those objects to another class/object (object 2: TableCell). The original array should still be retained in the original caller class. Then Object 2 is released, does that mean that that particular item in the array is released as well, as the reference to it in Object 2 was released? I am trying to better understand how to work with ManagedObjects as I get 'Object was released' errors. [EDIT] After some experimenting I came across the following scenario: I have the main AppDelegate. In a different class I create an AppDelegate to obtain the ManagedObjectContext. appDelegate = (iDomsAppDelegate *)[[UIApplication sharedApplication] delegate]; [self setContext:[appDelegate managedObjectContext]]; When the class is finished, and I release it, the variable in the class 'appDelegate' is also released. But then the ManagedObjectContext is closed, and obvious any future attempt to use it will cause a crash. So should I leave the appDelegate unreleased? This comes to the same question as the above about when and how to release in those situations where an objects is used from another class. I think a way of putting it is, how to know when you own an object and when not.

  • How does one make the camera on the iphone appear from the app delegate? Is it possible?

    - by K-RAN
    I'm just playing around with a simple program that opens the camera. That's literally all that I want to do. I'm a beginner and I believe that I have the basics down in terms of UI management for the iPhone so I decided to give this one a whirl. What I'm trying to do right now is... - (BOOL) application:(UIApplication*) application didFinishLaunchingWithOptions:(NSDictionary*) launchOptions { UIImagePickerController * camera = [[UIImagePickerController alloc] init]; camera.delegate = self; camera.sourceType = UIImagePickerControllerSourceTypeCamera; camera.allowsEditing = NO; camera.showsCameraControls = NO; [viewController presentModalViewController:camera animated:NO]; [window addSubview:viewController.view]; [window makeKeyAndVisible]; return YES: } So basically, initialize the camera, set some things and show it in the main view. I set the camera's delegate to self because this code is placed in the delegate class (and yes, the delegate class is conforming to UIImagePickerControllerDelegate && UINavigationControllerDelegate). Main problem right now is that nothing is appearing on the screen. I have absolutely no idea what I'm doing wrong, especially since the program is building correctly with no errors or warnings... Any help is appreciated! Thanks a lot :D

  • Why doesn't the SplitView iPhone template have a nib file for the RootView?

    - by Dr Dork
    I'm diving into iPad development and am learning a lot quickly, but everywhere I look, I have questions. After creating a new SplitView app in Xcode using the template, it generates the AppDelegate class, RootViewController class, and DetailViewController class. Along with that, it creates a .xib files for MainWinow.xib and DetailView.xib. How do these five files work together? Why is there a nib file for the DetailView, but not the RootView? When I double click on the MainWindow.xib file, Interface Builder launches without a "View" window, why? Below is the code for didFinishLaunchingWithOptions method inside the AppDelegate class. Why are we adding the splitViewController as a subview? (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after app launch rootViewController.managedObjectContext = self.managedObjectContext; // Add the split view controller's view to the window and display. [window addSubview:splitViewController.view]; [window makeKeyAndVisible]; return YES; } Thanks so much in advance for all your help! I still have a lot to learn, so I apologize if this question is absurd in any way. I'm going to continue researching these questions right now!

  • CoreData is saving model without the save: method being called

    - by chris
    I have a list of items with a plus button in the navigation bar that opens up a modal window containing a table of the models attributes, that displays a form when the table items are clicked (pretty standard form style). For some reason if I click the plus button to open the form to create a new model, then immediately click the done button, the person model is saved. The action linked to the done button does nothing but call on a delegate method notifying the personListViewController to close the window. The apple docs do state that the model is not saved after calling the insertNewObjectForEntityName: ... Simply creating a managed object does not cause it to be saved to a persistent store. The managed object context acts as a scratchpad. I am at a lost to why this is happening, but every time I click the done button I have a new blank item in the original tableView. I am using SDK v3.1.3 // PersonListViewController - open modal window - (void)addPerson { // Load the new form PersonNewViewController *newController = [[PersonNewViewController alloc] init]; newController.modalFormDelegate = self; [self presentModalViewController:newController animated:YES]; [newController release]; } // PersonFormViewController - (void)viewDidLoad { [super viewDidLoad]; if ( person == nil ) { MyAppDelegate *appDelegate = [[UIApplication sharedApplication] delegate]; self.person = [NSEntityDescription insertNewObjectForEntityForName:@"Person" inManagedObjectContext:appDelegate.managedObjectContext]; } ... UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(done)]; self.navigationItem.rightBarButtonItem = doneButton; [doneButton release]; } - (IBAction) done { [self.modalFormDelegate didCancel]; } // delegate method in the original listViewController - (void) didCancel { [self dismissModalViewControllerAnimated:YES]; }

  • UINavigationController not working under ARC in iPhone

    - by user1811427
    I have creared a new project "Empty Application" template in Xcode 4.3, it is having only two classes AppDelegate.h & .m I cheaked with ARC to use automatic reference count while creating the app. I added two new files "RootViewController" & "NewProjectViewControllers". I implemented code to set navigation controller as follows in AppDelegate - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; // Override point for customization after application launch. rootViewController = [[MainViewController alloc] init]; UINavigationController *navigation = [[UINavigationController alloc] initWithRootViewController:rootViewController]; [self.window addSubview:navigation.view]; self.window.backgroundColor = [UIColor whiteColor]; [self.window makeKeyAndVisible]; return YES; } and in hte home view (Root view controller) implemented as follows - (void)viewDidLoad { [super viewDidLoad]; self.title = @"Projects"; UINavigationBar *navigationBar = [self.navigationController navigationBar]; [navigationBar setTintColor: [UIColor colorWithRed:10/255.0f green:21/255.0f blue:51/255.0f alpha:1.0f]]; //To set the customised bar item UIButton *rightBarBtn = [UIButton buttonWithType:UIButtonTypeCustom]; [rightBarBtn setBackgroundImage:[UIImage imageNamed:@"plus_new.png"] forState:UIControlStateNormal]; rightBarBtn.frame=CGRectMake(0.0, 100.0, 30.0, 30.0); [rightBarBtn addTarget:self action:@selector(addProject) forControlEvents:UIControlEventTouchUpInside]; UIBarButtonItem* rightBarItem = [[UIBarButtonItem alloc] initWithCustomView:rightBarBtn]; self.navigationItem.rightBarButtonItem = rightBarItem; // Do any additional setup after loading the view from its nib. } - (void) addProject { NewProjViewController *editProject = [[NewProjViewController alloc] init]; [self.navigationController pushViewController:editProject animated:YES]; NSLog(@"xxxxxxxxxxxxxxx"); } But since i used ARC the navigation may dealoc immediately and it doesn't work, All the actions in method works except push to the next view if i do same thing with out ARC it works fine How to resolve this issue..? Thanks in advance

  • Multi-Part HTTP Request through xcode

    - by devsri
    Hello Everyone, i want to upload image,video and audio files to a server. I have read this thread on the similar topic but wasn't able to understand completely the flow of the code. It would be great if you can suggest me some sample code or tutorial to start with. I am using the following code to connect without any media to the server [UIApplication sharedApplication].networkActivityIndicatorVisible = YES; NSString *url =[[NSString alloc]initWithFormat:@"%@",[NetworkConstants getURL]]; NSURL *theURL =[NSURL URLWithString:url]; [url release]; NSMutableURLRequest *theRequest =[NSMutableURLRequest requestWithURL:theURL cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:0.0f]; [theRequest setHTTPMethod:@"POST"]; NSString *theBodyString = [NSString stringWithFormat:@"json1=%@&userID=%@",jsonObject,[GlobalConstants getUID]]; NSData *theBodyData = [theBodyString dataUsingEncoding:NSUTF8StringEncoding]; [theRequest setHTTPBody:theBodyData]; NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; if (conn) { NSLog(@"Successful in sending sync"); } else { NSLog(@"Failed Connection in sending sync"); } [conn release]; It would be really convenient for me if anything could be done editing this part of code. Any form of help would be highly appreciated. Thanks in advance!!

  • Knowing which annotation is selected and accessing properties of it.

    - by kevin Mendoza
    So far my program can display a database of custom annotation views. Eventually I want my program to be able to display extra information after a button on the annotation bubble is clicked. Each element in the database has a unique entry Number, so I thought it would be a good idea to add this entry number as a property of the custom annotation. The problem I am having is that after the button is clicked and the program switches to a new view I am unable to retrieve the entry number of the annotation I selected. Below is the code that assigns the entry Number property to the annotation: for (id mine in mines) { workingCoordinate.latitude = [[mine latitudeInitial] doubleValue]; workingCoordinate.longitude = [[mine longitudeInitial] doubleValue]; iProspectAnnotation *tempMine = [[iProspectAnnotation alloc] initWithCoordinate:workingCoordinate]; [tempMine setTitle:[mine mineName]]; [tempMine setAnnotationEntryNumber:[mine entryNumber]]; } [mines dealloc]; When the button on an annotation is selected, this is the code that initializes the new view: - (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control { mineInformationController *controller = [[mineInformationController alloc] initWithNibName:@"mineInformationController" bundle:nil]; controller.modalTransitionStyle = UIModalTransitionStyleCrossDissolve; [self presentModalViewController:controller animated:YES]; [controller release]; } and lastly is my attempt at retrieving the entryNumber property from the new view so that I can compare it to the mines database and retrieve more information on the array element. iProspectFresno_LiteAppDelegate *appDelegate = (iProspectFresno_LiteAppDelegate *)[[UIApplication sharedApplication] delegate]; NSMutableArray* mines = [[NSMutableArray alloc] initWithArray:(NSMutableArray *)appDelegate.mines]; for(id mine in mines) { if ([[mine entryNumber] isEqualToNumber: /*the entry Number of the selected annotation*/]) { /* display the information in the mine object */ } } So how do I access this entry number property in this new view controller?

  • Leftover Nav Bar in Landscape View

    - by Rob Bonner
    Hello, I am working to force a view into landscape mode, and have picked up all kinds of cool tips to make this happen, but am stuck on one item that is left on the screen. I have my XIB file laid out in landscape, and in my code I create the view controller normally: RedeemViewController *aViewController = [[RedeemViewController alloc] initWithNibName:@"RedeemViewController" bundle:nil]; aViewController.hidesBottomBarWhenPushed = YES; aViewController.wantsFullScreenLayout = YES; [[self navigationController] pushViewController:aViewController animated:YES]; Inside the controller viewDidLoad I complete the following: [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight]; [[self navigationController] setNavigationBarHidden:YES animated:YES]; [UIView beginAnimations:@"View Flip" context:nil]; [UIView setAnimationDuration:.75]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; if (self.interfaceOrientation == UIInterfaceOrientationPortrait) { self.view.transform = CGAffineTransformIdentity; self.view.transform = CGAffineTransformMakeRotation(degreesToRadian(90)); self.view.bounds = CGRectMake(0.0, 0.0, 480, 320); } [UIView commitAnimations]; What I end up with is a perfectly rotated view, with a grey vertical bar on the left side (see pic). So to the question, how do I get rid of the bar? Edit: I am pretty sure this is the navigation bar that is not being hidden. This is a duplicate of another post, with some modified code, the other question was being answered with the bug.

  • iPhone dev: UIBarButtonItem or title not showing up in NavigationBar

    - by IceMan85
    Hello everyone, here my problem. I have a NavigationBar at the top, a TabBar at the bottom and a TableView at the center of the screen. Very normal situation. I set it all up in IB and I have set this in the app delegate : ExpensesListNavController *expensesListNavController; This in order to be able to add new views to the stack. I need to have 3 levels: - list of items in a TableView - OK - firstLevel: once pressed one cell a view is added to the stack - OK - second level: one pressed the "modify" button on the navBar on the firstLevel I want to show a new view that can be customized by the user. My Problem is coming when trying to add the "Modify" button in the "firstLevelView". Here-below my code -(IBAction) modify:(id)sender { if (editableDetailViewController == nil) { editableDetailViewController = [[editableDetailViewController alloc] init]; } editableDetailViewController.expense = expense; [appDelegate.expensesListNavController pushViewController:editableDetailViewController animated:YES]; editableDetailViewController = nil; } // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; appDelegate = [[UIApplication sharedApplication] delegate]; UIBarButtonItem *modifyButton = [[UIBarButtonItem alloc] initWithTitle:@"Modify" style:UIBarButtonItemStylePlain target:self action:@selector(modify:)]; appDelegate.expensesListNavController.navigationItem.rightBarButtonItem = modifyButton; appDelegate.expensesListNavController.navigationItem.title = @"Titoloooo"; NSLog(@"NavBar button has just been set !!"); [modifyButton release]; Nothing is being showed, neither title nor the button. Do you have any idea of what is happening ?? I really cannot figure out !!! Thanks a lot in advance, AM

  • Xcode 4: nib files not loading when run, can't find UI elements

    - by Jordan
    So, I just downloaded Xcode 4 and installed it. I was actually quite looking forward to the single window and integrated IB... - However, when I open and run one of my projects, the nib files that the project uses don't seem to load. Instead I'm left looking at a blank white screen (iPhone). This project ran well and fine on Xcode 3.2. So I thought... this can't be that hard to fix. So I opened up a nib file, thinking that maybe editing or creating a new one from scratch could point me in the right direction. But I can't find the old resources panel from interface builder anywhere. How am I meant to create a new view or add buttons? I know I'm probably just missing something obvious :s Did anyone else have the same nib file problems - is there a fix (or something stupidly simple that I'm forgetting about)? - EDIT: Ok. If I background and un-background the app, the view loads fine. But this happens every time I build, on both iPhone and iOS simulator, i.e. the app doesn't work properly until it's been backgrounded. All the code for loading the view follows from - (void)applicationDidFinishLaunching:(UIApplication *)application. Now I am really confused. - Thanks :)

I am using the following code to open the Maps app. I am calling this code when a button is pressed. - (void)showDirectionsToHere { CLLocationCoordinate2D currentLocation = [self getCurrentLocation]; // LINE 1 NSString* url = [NSString stringWithFormat: @"http://maps.google.com/maps?saddr=%f,%f&daddr=%f,%f", destCoordinate.latitude + 0.1, destCoordinate.longitude, destCoordinate.latitude, destCoordinate.longitude];//8.3, 12.1 [[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]]; } Here [self getCurrentLocation] in LINE 1 uses CLLocationManager to determine the Current Location and returns the value. Note: I have not yet implemented the LINE1. I've just planned to do in that way. My question is, Is this a good practice to calculate the Current Location, at the time the Maps app is called? [self getCurrentLocation] will retrun the Current Location before openURL gets called? I have to determine the Current Location well before opening the Maps app? I am little bit confused about these things. Kindly guide me. Thanks.

  • How is an AppDelegate instanciated?

    - by pwny
    I have an iOS application for which I want to create a ViewController programmatically. I started an empty XCode project and modified the main method so it looks like this int main(int argc, char *argv[]) { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; int retVal = UIApplicationMain(argc, argv, nil, @"MyAppDelegate_iPad"); [pool release]; return retVal; } The app is a Universal Application, MyAppDelegate_iPad is a subclass of MyAppDelegate, which is a subclass of NSObject <UIApplicationDelegate>. My problem is that the applicationDidFinishLoading method I've overridden in MyAppDelegate_iPad is never called (break point on the first line never hits). The method looks like this -(void) applicationDidFinishLaunching:(UIApplication *)application { window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; if(!window) { [self release]; return; } window.backgroundColor = [UIColor whiteColor]; rootController = [[MyViewController alloc] init]; [window addSubview:rootController.view]; [window makeKeyAndVisible]; [window layoutSubviews]; } I removed the line to link to a nib file from my plist file (I used to get the default "My Universal app on iPad" white screen) and now all that is displayed is a black screen. applicationDidFinishLoading is still not being called. Am I doing something wrong? How should I properly create my AppDelegate instance?

  • ViewController behaving oddly when pushed on the window

    - by ayazalavi
    I am using multiple controller during launch of an application in app delegate. One controller is for registration and the second controller is tabbar. tabbar was loading fine but when I pushed registration controller on window, contents went up by 20 units and I have good white blank screen at bottom. Therefore I recreated frame of my registration view controller in its viewdidload method and slided it 20 units down. The code is self.view.frame = CGRectMake(0, 20, self.view.frame.size.width, self.view.frame.size.height); and code in my app delegate for launch application was - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { if (![self accountExists]) { //code if account does not exists on iphone app database self.registerAccount = [[registerViewController alloc] initWithNibName:@"registerViewController" bundle:nil]; [window addSubview:registerAccount.view]; } else if([self autoLoginForAnyAccount]){ //code for autologin to app } else { self.tabBarController.selectedIndex = 1; self.tabBarController.delegate = self; [window addSubview:tabBarController.view]; } [window makeKeyAndVisible]; return YES; } if anyone knows why there is a white space at bottom when registration controller is pushed then please share it with me.

  • long startup time...Need help

    - by Jeff
    My app is all done and working great. So now I ran it on a old iPhone and the app takes 17.3 seconds to start!?!? i spent a lot of time looking into it and i found that the reason it is taking so long to load is i have a lot of views and each view has a png background image. All my views and made in IB and in my code: #import "MyTestAppDelegate.h" #import "MyTestViewController.h" @implementation MyTestAppDelegate @synthesize window; @synthesize viewController; - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after app launch [window addSubview:viewController.view]; [window makeKeyAndVisible]; } - (void)dealloc { [viewController release]; [window release]; [super dealloc]; } @end At the end of the code where is says: [window addSubview:viewController.view]; the app seems to be loading all the views in the nib at the same time. All the png's from all the views are about 12mb. There is no need for the app to load all the views at the same time during startup. Is there a way i can only load the first "home" view at startup? (All the views are part of the same nib.)

    - by monish
    Hi Guys, Here I am fighting with a problem couple of hours. My problem is Here is my code in appdelegate didFinishLaunching method. #import "CorkItAppDelegate.h" @implementation CorkItAppDelegate @synthesize window,isPicker,isFirstTime,winTyp,winTypId,wineCatName,wineRegName,theViewController,catId,regId,facebookObject,isGetWineName,getNewWineName,isNewWine,getNewWineReg,isNewReg,wineDetPk,currentLocation,internetConnectionStatus; static NSString* mapCurrentLocationUrlArg = @"http://maps.google.com/maps?q=%s@"; - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after application launch //facebookObject=[[FacebookMyLib alloc]init]; [self createEditableCopyOfDatabaseIfNeeded]; [self initializeDataStructures]; [MyCLController sharedInstance].delegate = self; [[MyCLController sharedInstance].locationManager startUpdatingLocation]; isGetWineName = NO; facebookObject = [[FacebookMyLib alloc] init]; theViewController = [[[MasterViewController alloc] init]autorelease]; UINavigationController* controller = [[UINavigationController alloc] initWithRootViewController:theViewController]; controller.navigationBar.barStyle = UIBarStyleBlackOpaque; [window addSubview:controller.view]; [window makeKeyAndVisible]; } here in this code I declared the MasterView controller globally in .h class. and it written property and synthesize for that. But when I run the build I am getting two errors at #import "MasterViewController" like error:expected specifier-qualifier-list before 'MasterViewController'. can anyone suggest me how to get rid of this. Anyone's help will be much Appreciated. Thank you, Monish.
