  • How do I set an ABPeoplePickerNavigationController's prompt?

    - by mverzilli
    This is the code I'm using to call the people picker, but the prompt label text doesn't change: ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init]; picker.peoplePickerDelegate = self; picker.displayedProperties = [NSArray arrayWithObjects: [NSNumber numberWithInt:kABPersonEmailProperty], nil]; picker.navigationItem.prompt = @"Choose a contact to..."; [self presentModalViewController:picker animated:YES];

  • IconDownloader, problem with lazy downloading

    - by Junior B.
    My problem is simple to be described but it seems to be hard to solve. The problem is loading icons, with a custom class like IconDownloader.m provided by an official example from Apple, avoiding crashes if I release the view. I've added the IconDownloader class to my app, but it's clear that this approach is good only if the tableview is the root. The big problem is when the view is not the root one. F.e: if I start to scroll my second view (the app now load the icons) and, without leaving it the time to finish the download, I go back to root, the app crash because the view that have to be updated with new icons doesn't exist anymore. One possible solution could be implement an OperationQueue in the view, but with this approach I've to stop the queue when I change the view and restart it when I come back and the idea to have N queues don't make me enthusiastic. Anyone found a good solution for this problem?

  • Unable to pass variables from one view to another

    - by jerincbus
    I have a detail view that includes three UIButtons, each of which pushes a different view on to the stack. One of the buttons is connected to a MKMapView. When that button is pushed I need to send the latitude and longitude variables from the detail view to the map view. I'm trying to add the string declaration in the IBAction: - (IBAction)goToMapView { MapViewController *mapController = [[MapViewController alloc] initWithNibName:@"MapViewController" bundle:nil]; mapController.address = self.address; mapController.Title = self.Title; mapController.lat = self.lat; mapController.lng = self.lng; //Push the new view on the stack [[self navigationController] pushViewController:mapController animated:YES]; [mapController release]; mapController = nil; } But I get this when I try to build: 'error: incompatible types in assignment' for both lat and lng variables. So my questions are am I going about passing the variables from one view to another the right way? And does the MKMapView accept latitude and longitude as a string or a number?

  • How to cast an NSDecimal value into an NSInteger value?

    - by mystify
    I have an situation where I get an NSDecimal, and I need an NSInteger. I do know it is a very small value (this is absolutely sure). It won't be bigger than 100. So It would be perfectly fine to cast it to NSInteger, no overflow would happen. How could this be done? There's just an -doubleValue method in NSDecimal.

  • Resizing UIView to match its content

    - by Thody
    I have a UITextField, a UIButton, and a UIWebView nested in a UIView, which is nested in a UIScrollView. After the UIWebView has loaded its content, I need it to resize the UIWebView and UIView so that the UIScrollView will scroll. I currently have the UIScrollView getting its contentSize from the UIView, but I can't figure out how to do the resizing after the UIWebView's content has loaded.

  • Nested Views-button aint clicking

    - by Deepika
    i have a view which has a datepicker and a button added to it. There is another view which adds the above view as subview. But the events like touchesBegan and button's action are not being clicked on the subview. Please help The code of the parent view is: iTagDatePicker *dt=[[iTagDatePicker alloc] initWithFrame:CGRectMake(0.0, 180.0, 320.0, 240.0)]; //dt.userInteractionEnabled=YES; //[dt becomeFirstResponder]; dt.backgroundColor=[UIColor clearColor]; [UIView beginAnimations:@"animation" context:nil]; [UIView setAnimationDuration:1.0]; CGPoint cntr; cntr.x=160.0; cntr.y=420.0; dt.center=cntr; [self.view addSubview:dt]; self.view.userInteractionEnabled=YES; CGPoint cntr1; cntr1.x=160.0; cntr1.y=158.0; dt.center=cntr1; [UIView commitAnimations]; [dt release]; and the code for the sub class is: - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { dtPicker=[[UIDatePicker alloc] initWithFrame:CGRectMake(frame.origin.x, frame.origin.y, 320.0, 216.0)]; dtPicker.datePickerMode=UIDatePickerModeDate; dtPicker.date=[NSDate date]; [self addSubview:dtPicker]; btn=[[UIButton buttonWithType:UIButtonTypeDetailDisclosure]retain]; btn.frame=CGRectMake(110.0, 400.0, 100.0, 20.0); [btn setTitle:@"Done" forState:UIControlStateNormal]; btn.userInteractionEnabled=YES; [btn becomeFirstResponder]; [btn addTarget:self action:@selector(SelectedVal:) forControlEvents:UIControlEventTouchDown]; [self addSubview:btn]; } return self; } The button is not working

  • Compare two Xcode build settings

    - by John Smith
    I have a project where I use two build settings predominantly. Unfortunately today something went wrong. One compiles and the other doesn't. How can I compare the two build settings in XCode to see what the differences are? (For those interested, the error I get in one build is jump to case label crosses initialization of 'const char* selectorName' if you know what this means I'll be very grateful )

  • Hiding a Bar button item in the view

    - by devb0yax
    How can you able to hide the (done) bar button item in a view? Basically, I have a view controller added with navigation bar (in IB) then, I also added a bar button item into the nav bar. I just want initially the (done) bar button item is hidden.. when input is in the text view the (done) button is already visible. Any idea on this implementation on a view controller? Here's my sample code: @interface MyTextViewViewController : UIViewController <UITextViewDelegate> { UITextView *m_textView; UIBarButtonItem *doneBarButtonItem; } @property(nonatomic,retain) IBOutlet UITextView *m_textView; @property(nonatomic,retain) IBOutlet UIBarButtonItem *doneBarButtonItem; - (IBAction)saveAction:(id)sender; .m file: - (void)viewDidLoad { [super viewDidLoad]; doneBarButtonItem.hidden = YES; --> compile error!!! } - (void)textViewDidBeginEditing:(UITextView *)textView { doneBarButtonItem.hidden = NO; --> compile error!!! } - (IBAction)saveAction:(id)sender { doneBarButtonItem.hidden = YES; --> compile error!!! ... }

  • Core Data and BOOL setup

    - by John Valen
    I am working on an app that uses Core Data as its backend for managing SQLite records. I have everything working with strings and numbers, but have just tried adding BOOL fields and can't seem to get things to work. In the .xcdatamodel, I have added a field to my object called isCurrentlyForSale which is not Optional, not Transient, and not Indexed. The attribute's type is set to Boolean with default value NO. When I created the class files from the data model, the boilerplate code added for this property in the .h header was: @property (nonatomic, retain) NSNumber * isCurrentlyForSale; along with the @dynamic isCurrentlyForSale; in the .m implementation file. I've always worked with booleans as simple BOOLs. I've read that I could use NSNumber's numberWithBool and boolValue methods, but this seems like an aweful lot of extra code for something so simple. Can the @property in the header be changed to a simple BOOL? If so is there anything to watch out for? Thanks -John

  • Can't add to NSMutableArray from SecondaryView

    - by Antonio
    Hi guys, I've searched and read and still haven't found a concrete answer. Brief: I have an application where I declare an NSMutableArray in my AppDelegate to synthesize when the application loads. (code below). I have a SecondaryViewController call this function, and I have it output a string to let me know what the array size is. Every time I run it, it executes but it does not add any objects to the array. How do I fix this? AppDelegate.h file #import <UIKit/UIKit.h> @class arrayTestViewController; @interface arrayTestAppDelegate : NSObject <UIApplicationDelegate> { UIWindow *window; arrayTestViewController *viewController; NSMutableArray *myArray3; } @property (nonatomic, retain) NSMutableArray *myArray3; @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet arrayTestViewController *viewController; -(void)addToArray3; @end AppDelegate.m file #import "arrayTestAppDelegate.h" #import "arrayTestViewController.h" @implementation arrayTestAppDelegate @synthesize window; @synthesize viewController; @synthesize myArray3; #pragma mark - #pragma mark Application lifecycle - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { myArray3 = [[NSMutableArray alloc] init]; // Override point for customization after application launch. // Add the view controller's view to the window and display. [window addSubview:viewController.view]; [window makeKeyAndVisible]; return YES; } -(void)addToArray3{ NSLog(@"Array Count: %d", [myArray3 count]); [myArray3 addObject:@"Test"]; NSLog(@"Array triggered from SecondViewController"); NSLog(@"Array Count: %d", [myArray3 count]); } SecondViewController.m file #import "SecondViewController.h" #import "arrayTestAppDelegate.h" @implementation SecondViewController -(IBAction)addToArray{ arrayTestAppDelegate *object = [[arrayTestAppDelegate alloc] init]; [object addToArray3]; }

  • Memory leak when declaring NSString from ABRecordCopyValue

    - by Ben Thompson
    I am using the following line of code... NSString *clientFirstName = (NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty); The 'analyse' feature on Xcode is saying that this giving rise to a potential memory leak. I am not releasing clientFirstName at all as I have neither alloc or retain'd it. However, I am conscious that ABRecordCopyValue may not be returning an object as say a command like [NSMutableArray arrayWithArray:someArray] would which might mean I am indeed creating a new object that I control and must release. Keen to hear thoughts...

  • UIScrollView eating touches from its parent

    - by Jon Hull
    I have nested scrollViews (or rather a subclass of UIScrollView inside of an actual scrollview). I set the size of the inner view to its contentSize and set scrollEnabled = NO, because I only want the outside view scrolling. But the innerView occasionally eats touches and keeps the outerView from scrolling when it should. Is there something else I need to set to keep it from stealing the scrolling touches, but still allowing user interaction (e.g. editing a textView)?

  • Can I safely store UInt32 to NSUInteger?

    - by mystify
    In the header, it is defined like: #if __LP64__ || (TARGET_OS_EMBEDDED && !TARGET_OS_IPHONE) || TARGET_OS_WIN32 || NS_BUILD_32_LIKE_64 typedef long NSInteger; typedef unsigned long NSUInteger; #else typedef int NSInteger; typedef unsigned int NSUInteger; #endif So does an UInt32 fit without problems into an NSUInteger (an unsigned int)? Where's the difference between UInt32 and unsigned int? And I assume that an unsigned long is bigger than an unsigned int?

  • Custom cell and Delete/Move indicators

    - by Kamchatka
    Hello, I have a custom UITableViewCell. However, when I got in edit mode, I don't have any Delete and Move indicators appearing. The custom cell draws itself in the contentView. In layoutSubviews, I make sure there is space on the left and one the right of the contentView so that the controls can appear (if this was the problem). - (void)layoutSubviews { self.contentView.frame = CGRectMake(50, 0, self.frame.size.width - 100, sub.thumbnail.size.height + 20); } In the UITableViewController, I return YES in: - (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath { How could I solve this lack of interactivity. Is there something specific for custom cells? Thanks!

  • Integer Extensions - 1st, 2nd, 3rd etc [closed]

    - by David Schiefer
    Possible Duplicate: NSNumberFormatter and ‘th’ ‘st’ ‘nd’ ‘rd’ (ordinal) number endings Hello, I'm building an application that downloads player ranks and displays them. So say for example, you're 3rd out of all the players, I inserted a condition that will display it as 3rd, not 3th and i did the same for 2nd and 1st. When getting to higher ranks though, such as 2883rd, it'll display 2883th (for obvious reasons) My question is, how can I get it to reformat the number to XXX1st, XXX2nd, XXX3rd etc? To show what I mean, here's how I format my number to add a "rd" if it's 3 if ([[container stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]] isEqualToString:@"3"]) { NSString*badge = [NSString stringWithFormat:@"%@rd",[container stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]]; NSString*scoreText = [NSString stringWithFormat:@"ROC Server Rank: %@rd",[container stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]]; profile.badgeValue = badge; rank.text = scoreText; } I can't do this for every number up to 2000 (there are 2000 ranks in total) - what can I do to solve this problem?

  • GKSession sendDataToAllPeers including sendee?

    - by Typeoneerror
    I've got a number of devices connected over wifi using GameKit. I have a simple UIAlertView popping up when peers receive data. All but the sendee show this alert view when data is sent, so I'm wondering if that's a bug in my app or if that's expected behavior. Should call a method manually at the same on the sendee device? For example, if I wanted to send a "GameStart" packet to the 4 phones, the peers would call startGame: in the receiveData:fromPeer:inSession:context: method when it receives that packet and the sendee would just sendData and call startGame: on itself. Does that sound right or is there a way to include the sendee in the sendData list so that it responds exactly the same as all connected peers?

  • IUNavigationController loading more viewControllers

    - by Goods
    Not a Noob as yesterday, but still green. I have a UITabbarcontoller and a IUNavigationController they seem to work fine. I have a UITableviewController to which I loads my NSMutable array. The user clicks a cell and didSelectRowAtIndexPath xib is loaded onto the stack. I have a 'Learn More' button on the current xib. I've tried a few approaches to load a newer xib when the 'Learn More' button is pressed but have failed. Im thinking it has to do with the Navigation Controller? Do I need to import the navigationcontroller to every ViewControllerSubclass I make? Thanks.

  • Is this an UITableView -beginUpdates documentation error?

    - by mystify
    I can't wrap my head around what they tried to say here in the docs for -beginUpdate: Call this method if you want subsequent insertions, deletion, and selection operations (for example, cellForRowAtIndexPath: and indexPathsForVisibleRows) to be animated simultaneously. Let's see... cellForRowAtIndexPath: and indexPathsForVisibleRows are both GETTER methods. They do not update anything and do not change anything. So why should I call -beginUpdates before calling these? And what's animated regarding these? Well, nothing, huh? Just want to make sure this is really an error in the docs and I didn't miss something.
