  • 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?

  • I'm trying to pass a string from my first ViewController to my second ViewController but it returns NULL

    - by Dashony
    In my first view controller I have 3 input fields each of them take the user input into and saves it into a string such as: address, username and password as NSUserDefaults. This part works fine. In my second view controller I'm trying to take the 3 strings from first controller (address, username and password) create a html link based on the 3 strings. I've tried many ways to access the 3 strings with no luck, the result I get is NULL. Here is my code: //.h file - first view controller with the 3 input fields CamSetup.h #import <UIKit/UIKit.h> @interface CamSetup : UIViewController <UITextFieldDelegate> { NSString * address; NSString * username; NSString * password; IBOutlet UITextField * addressField; IBOutlet UITextField * usernameField; IBOutlet UITextField * passwordField; } -(IBAction) saveAddress: (id) sender; -(IBAction) saveUsername: (id) sender; -(IBAction) savePassword: (id) sender; @property(nonatomic, retain) UITextField *addressField; @property(nonatomic, retain) UITextField *usernameField; @property(nonatomic, retain) UITextField *passwordField; @property(nonatomic, retain) NSString *address; @property(nonatomic, retain) NSString *username; @property(nonatomic, retain) NSString *password; @end //.m file - first view controller CamSetup.m #import "CamSetup.h" @interface CamSetup () @end @implementation CamSetup @synthesize addressField, usernameField, passwordField, address, username, password; -(IBAction) saveAddress: (id) sender { address = [[NSString alloc] initWithFormat:addressField.text]; [addressField setText:address]; NSUserDefaults *stringDefaultAddress = [NSUserDefaults standardUserDefaults]; [stringDefaultAddress setObject:address forKey:@"stringKey1"]; NSLog(@"String [%@]", address); } -(IBAction) saveUsername: (id) sender { username = [[NSString alloc] initWithFormat:usernameField.text]; [usernameField setText:username]; NSUserDefaults *stringDefaultUsername = [NSUserDefaults standardUserDefaults]; [stringDefaultUsername setObject:username forKey:@"stringKey2"]; NSLog(@"String [%@]", username); } -(IBAction) savePassword: (id) sender { password = [[NSString alloc] initWithFormat:passwordField.text]; [passwordField setText:password]; NSUserDefaults *stringDefaultPassword = [NSUserDefaults standardUserDefaults]; [stringDefaultPassword setObject:password forKey:@"stringKey3"]; NSLog(@"String [%@]", password); } - (void)viewDidLoad { [addressField setText:[[NSUserDefaults standardUserDefaults] objectForKey:@"stringKey1"]]; [usernameField setText:[[NSUserDefaults standardUserDefaults] objectForKey:@"stringKey2"]]; [passwordField setText:[[NSUserDefaults standardUserDefaults] objectForKey:@"stringKey3"]]; [super viewDidLoad]; } @end //.h second view controller LiveView.h #import <UIKit/UIKit.h> #import "CamSetup.h" @interface LiveView : UIViewController { NSString *theAddress; NSString *theUsername; NSString *thePassword; CamSetup *camsetup; //here is an instance of the first class } @property (nonatomic, retain) NSString *theAddress; @property (nonatomic, retain) NSString *theUsername; @property (nonatomic, retain) NSString *thePassword; @end //.m second view LiveView.m file #import "LiveView.h" @interface LiveView () @end @implementation LiveView @synthesize theAddress, theUsername, thePassword; - (void)viewDidLoad { [super viewDidLoad]; theUsername = camsetup.username; //this is probably not right?

  • Android Apps Not Showing Up In AVD

    - by Mike
    I recently started messing with Android Apps, but I have had nothing but problems trying to get them into the Virtual Device for testing. For some reason, they never seem to show up in the AVD. It has worked one time, but that's it out of hours spent just trying to test one or two very simple apps. I've redone the AVD setup many, many times, trying different settings and what not to no avail. I've followed multiple guides and tutorials to the letter to get it working, but they just refuse to show up in the list. :( Any insight would be appreciated, thank you.

  • Using setters On Int?

    - by fuzzygoat
    Just curious, given: unsigned int pulseCounter_001; @property(nonatomic, assign)unsigned int pulseCounter_001; @synthesize pulseCounter_001; Is there any reason to use: [self setPulseCounter_001:0]; Or just use: pulseCounter_001 = 0; Style wise I think the latter says "we are setting an int" better, just curious as to any overheads involved in each? gary

  • UIWebView not evaluating javascript properly

    - by jammur
    I'm trying to run some javascript against a UIWebView but it's doesn't seem to be working. For example, here is a snippet of html I'm using to test: <html><body><h1>Hello World!</h1><p>It's me.</p></body></html> If I run the following javascript against it, the return value is 0, when it should be 1. var elements = document.getElementsByTagName("h1"); elements.length; Here's the objc code I'm using for the webview. 'parser' is a string containing the above javascript: [webView loadHTMLString:@"<html><body><h1>Hello World!</h1><p>It's me.</p></body></html>" baseURL:nil]; NSString *markupResult = [webView stringByEvaluatingJavaScriptFromString:parser];

  • Multi-property "transactions" in Core Data / NSManagedObject / NSFetchedResultsController?

    - by Martijn Thé
    Hi, Is it possible to set multiple properties of an NSManagedObject and have the NSFetchedResultsController call controllerDidChangeContent: only once? In other words, is it possible to say something like: [managedObject beginChanges]; [managedObject setPropertyA:@"Foo"]; [managedObject setPropertyB:@"Bar"]; [managedObject commitChanges]; and then have the NSFetchedResultsController call controllerDidChangeContent: (and the other methods) only one time? Thanks!

  • Navigation Within TabController

    - by David.Chu.ca
    I am trying to use UITabController as may controller in my main window and add navigation controllers to some tab bar items. For example, the first tab has a navigation controller with table view: ![alt text][1] The SettingsViewController is associated with its own NIB file, where a table view is defined. Within that xib file, I have a table view and set it to the outlet of SettingsViewController class property myTableView. The problem is that in the main xib file, for the SettingsViewController navigation, there is one outlet myTableView. I am not sure if I have to set this to somewhere? The exception I get is "[UIViewController _loadViewFromNibNamed:bundle:] loaded the "SettingsViewController" nib but the view outlet was not set." [1]:

    - by Incognitii
    I've noticed that even though I placed my sqlite3 database in the "resources" folder, and even though I checked the "Copy file" box, when I do a build, XCode creates an empty database toi the application folder it's building...so it's FINDING the database, and OPENING it, but there's nothing IN it, so when I do a sqlite3_prepare_v2, I get a SQLITE_ERROR... Help! What am I doing wrong?

  • 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?

  • Concept: Mapping irregular shapes (cartoons, sprites) to triangles in OpenGL ES

    - by Moshe
    I understand how mapping a triangle texture to a triangle works, but how do you map other things? I can't see myself mapping a circle onto a triangle. If it were a quad (square), I could see it happening, but why would a graphic not get warped on a triangle? EDIT: Bonus question: What are some good OpenGL ES tutorials online? Videos and articles count. (I've seen the Stanford University stuff on iTunes U and think it's excellent, but I want more.)

  • CGAL replacement for iOS

    - by Aleks N.
    I have a set of nodes that define streets. Each node has latitude and longitude. Also I have user location with latitude and longitude. My intention is to build Voronoi diagram for segments defined by each pair of nodes, and then find which node user location is closest to. Looks like this task can be accomplished with CGAL library. While I'm in the process of compiling it for iOS environment, probably you guys will be able to give links to libs that are already compiled against iOS, or were intended to be used in Objective C environment from the very beginning... Because I'm afraid that even if CGAL compiles for me, I might get into trouble when using it. Thanks!

What i am trying shows in code - (void)drawTextInContext:(CGContextRef)ctx { CGContextSaveGState(ctx); CGFloat width = self.bounds.size.width; CGFloat height = self.bounds.size.height; CGFloat numberFontSize = floorf(0.3f * width); CGContextSetFillColorWithColor(ctx, kDarkCharcoalColor); CGContextSetTextDrawingMode(ctx, kCGTextClip); for (NSInteger i = 0; i < [self.text length]; i++) { NSString *letter = [self.text substringWithRange:NSMakeRange(i, 1)]; CGSize letterSize = [letter sizeWithFont:[UIFont boldSystemFontOfSize:numberFontSize]]; CGContextSaveGState(ctx); // I will need to undo this clip after the letter's gradient has been drawn [letter drawAtPoint:CGPointMake(4.0f+(letterSize.width*i), 0.0f) withFont:[UIFont boldSystemFontOfSize:numberFontSize]]; if ([self.date isToday]) { CGContextSetFillColorWithColor(ctx, kWhiteColor); CGContextFillRect(ctx, self.bounds); } else { // CGContextDrawLinearGradient(ctx, TextFillGradient, CGPointMake(0,0), CGPointMake(0, height/3), kCGGradientDrawsAfterEndLocation); CGDataProviderRef dataProvider = CGDataProviderCreateWithFilename("left-arrow.png"); CGImageRef image = CGImageCreateWithPNGDataProvider(dataProvider, NULL, NO, kCGRenderingIntentDefault); //UIImage* image = [UIImage imageNamed:@"left-arrow.png"]; //CGImageRef imageRef = image.CGImage; CGContextDrawImage(ctx, CGRectMake(8.0f+(letterSize.width*i), 0.0f, 5, 5), image); //im.image=[UIImage imageNamed:@"left-arrow.png"]; } CGContextRestoreGState(ctx); // get rid of the clip for the current letter } CGContextRestoreGState(ctx); } In else condition i want to show images on the tile so for that i am converting image objects in the CGContextDrawImage. Please help me. I am not sure this would be done in same manner or in other manner please suggest your way to do this. Thanx a lot.

  • launch an app to record keep with greasemonkey

    - by acidzombie24
    I have my greasemonkey script scanning every page i visit for a specific string. I would like to recordkeep the variations of the string in a sqlite db. I'll have another app process this db everyonce in a while. What i dont know is HOW do i store the data into the sqlite db? i was thinking i can launch an executable automatically if the string was found but i dont know how to do that through javascript. Another alternative i thought was have a socket listen on a certain port and have some js magic but i couldnt think of a silent way to send data like that.

  • Where is the best place to run initialization code for a UITabBarController?

    - by bobobobo
    I have a UITabBarController in my application. I have to perform some customization to the NIB file using code the first time a view embedded in that UITabBarController gets loaded. When applicationDidFinishLaunching occurs, the UITabBarController's views apparently are not loaded -- if I try to modify the view controllers inside a tab bar that the tab bar is to load in applicationDidFinishLaunching, then those changes are ignored. I'm assuming this is because the tab bar didn't finish loading yet. So, I need a good place to put code that will run immediately after a tabbar is fully ready -- i.e. after it has loaded all the views from their respective nib files. I'm finding the only place I can do this is to track the first time viewDidAppear on each individual view controller. Note I can't use viewWillAppear because I need the value of tabBarController.selectedIndex to be accurate, and it is only actually updated after viewDidAppear gets fired, not when viewWillAppear gets fired.

  • 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?

  • Moving UIButton around

    I've tried to move a UIButton up and down in a menu. The problem I've got with the following solution is that the timer is not accurate. Sometimes the Button is moved up 122px, sometimes only 120px. How I can fix this? -(IBAction)marketTabClicked:(id)sender { if (marketTabExtended) { NSLog(@"marketTabExtended = YES"); return; } else { if (iPhoneAppsExtended) { timer = [NSTimer scheduledTimerWithTimeInterval:0.005 target: self selector: @selector(animateItemApps) userInfo: nil repeats: YES]; } else { if (homepageExtended) { timer = [NSTimer scheduledTimerWithTimeInterval:0.005 target: self selector: @selector(animateItemHomepage) userInfo: nil repeats: YES]; } else { timer = [NSTimer scheduledTimerWithTimeInterval:0.005 target: self selector: @selector(animateItemMarketing) userInfo: nil repeats: YES]; } } } [self performSelector:@selector(stopTimer) withObject:self afterDelay:0.605]; iPhoneAppsExtended = NO; homepageExtended = NO; marketTabExtended = NO; marketTabExtended = YES; } -(void)animateItemApps { CGPoint movement; movement = CGPointMake(0, -1); homepage.center = CGPointMake(homepage.center.x, homepage.center.y + movement.y); } -(void)animateItemHomepage { CGPoint movement; movement = CGPointMake(0, 1); homepage.center = CGPointMake(homepage.center.x, homepage.center.y + movement.y); //marketTab.center = CGPointMake(marketTab.center.x, marketTab.center.y + movement.y); } -(void)animateItemMarketing { CGPoint movement; movement = CGPointMake(0, -1); //marketTab.center = CGPointMake(marketTab.center.x, marketTab.center.y + movement.y); homepage.center = CGPointMake(homepage.center.x, homepage.center.y + movement.y); } -(void)stopTimer { [timer invalidate]; }

  • Get notification when NSOperationQueue finishes all tasks

    - by porneL
    NSOperationQueue has waitUntilAllOperationsAreFinished, but I don't want to wait synchronously for it. I just want to hide progress indicator in UI when queue finishes. What's the best way to accomplish this? I can't send notifications from my NSOperations, because I don't know which one is going to be last, and [queue operations] might not be empty yet (or worse - repopulated) when notification is received.

  • How can I Query only __key__ on a Google Appengine PolyModel child?

    - by Gabriel
    So the situation is: I want to optimize my code some for doing counting of records. So I have a parent Model class Base, a PolyModel class Entry, and a child class of Entry Article: How would I query Article.key so I can reduce the query load but only get the Article count. My first thought was to use: q = db.GqlQuery("SELECT __key__ from Article where base = :1", i_base) but it turns out GqlQuery doesn't like that because articles are actually stored in a table called Entry. Would it be possible to Query the class attribute? something like: q = db.GqlQuery("select __key__ from Entry where base = :1 and :2 in class", i_base, 'Article') neither of which work. Turns out the answer is even easier. But I am going to finish this question because I looked everywhere for this. q = db.GqlQuery("select __key__ from Entry where base = :1 and class = :2", i_base, 'Article')
