  • Finding user location before map loads

    - by 4thSpace
    I'm trying to find the user's location using: CLLocationCoordinate2D _location; CLLocation *userLoc = nil; if(appDelegate.clLocationManager.locationServicesEnabled){ userLoc = mapView.userLocation.location; _location = userLoc.coordinate; } The problem is that I haven't yet initialized the map so the above doesn't work. Is there a way to get the user's location without using mapkit? Or should I be using a different technique?

  • Why does UIActionSheet cancel crahes my App?

    - by Tim Büthe
    I try to use the UIActionSheet within my iPhone App but have the following problem. When I tap the cancel button "I don't", the app crashes. When I remove the NSLog statement from the actionSheet:clickedButtonAtIndex: it does not. The "Yes, do it" button works just fine and I see the log statement in the console. What's wrong? - (void) doItWithConfirm { UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"do you really wanna do it?" delegate:self cancelButtonTitle:@"I don't" destructiveButtonTitle: nil otherButtonTitles:@"Yes, do it", nil]; [actionSheet showInView:self.view]; [actionSheet release]; } - (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { NSLog(@"buttonIndex: %@", buttonIndex); }

  • Global NSMutableArray doesn't seem to be holding values

    - by diatrevolo
    I have a Cocos2D iPhone application that requires a set of CGRects overlaid on an image to detect touches within them. "Data" below is a class that holds values parsed from an XML file. "delegateEntries" is a NSMutableArray that contains several "data" objects, pulled from another NSMutableArray called "entries" that lives in the application delegate. For some strange reason, I can get at these values without problems in the init function, but further down the class in question, I try to get at these values, and the application crashes without an error message (as an example, I put in the "ccTouchBegan" method which accessess this data through the "populateFieldsForTouchedItem" method. Can anyone see why these values would not be accessible from other methods? No objects get released until dealloc. Thanks in advance! @synthesize clicked, delegate, data, image, blurImage, normalImage, arrayOfRects, delegateEntries; - (id)initWithTexture:(CCTexture2D *)aTexture { if( (self=[super initWithTexture:aTexture] )) { arrayOfRects = [[NSMutableArray alloc] init]; delegateEntries = [[NSMutableArray alloc] init]; delegate = (InteractivePIAppDelegate *)[[UIApplication sharedApplication] delegate]; delegateEntries = [delegate entries]; data = [delegateEntries objectAtIndex:0]; NSLog(@"Assigning %@", [[delegateEntries objectAtIndex:0] backgroundImage]); NSLog(@"%@ is the string", [[data sections] objectAtIndex:0]); //CGRect rect; NSLog(@"Count of array is %i", [delegateEntries count]); //collect as many items as there are XML entries for(int i=0; i<[delegateEntries count]; i++) { if([[delegateEntries objectAtIndex:i] xPos]) { NSLog(@"Found %i items", i+1); [arrayOfRects addObject:[NSValue valueWithCGRect:CGRectMake([[[delegateEntries objectAtIndex:i] xPos] floatValue], [[[delegateEntries objectAtIndex:i] yPos] floatValue], [[[delegateEntries objectAtIndex:i] xBounds] floatValue], [[[delegateEntries objectAtIndex:i] yBounds] floatValue])]]; } else { NSLog(@"Nothing"); } } //remove the following once the NSMutableArray from above works (legacy) blurImage = [[NSString alloc] initWithString:[data backgroundBlur]]; NSLog(@"5"); normalImage = [[NSString alloc] initWithString:[data backgroundImage]]; clicked = NO; } return self; } And then: - (void)populateFieldsForTouchedItem:(TouchedRect)touchInfo { Data *touchDatum = [[Data alloc] init]; touchDatum = [[self delegateEntries] objectAtIndex:touchInfo.recordNumber]; NSLog(@"Assigning %@", [[[self delegateEntries] objectAtIndex:touchInfo.recordNumber] backgroundImage]); rect = [[arrayOfRects objectAtIndex:touchInfo.recordNumber] CGRectValue]; image = [[NSString alloc] initWithString:[[touchDatum sections] objectAtIndex:0]]; [touchDatum release]; } - (BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event { TouchedRect touchInfo = [self containsTouchLocation:touch]; NSLog(@"Information pertains to %i", touchInfo.recordNumber); if ( !touchInfo.touched && !clicked ) { //needed since the touch location changes when zoomed NSLog(@"NOPE"); return NO; } [self populateFieldsForTouchedItem:touchInfo]; NSLog(@"YEP"); return YES; }

I couldn't find a working solution! Can you please give me a clue? Thanks, Julian.

  • Animation on single UIWebView

    - by Shri
    I have searched quite a bit(sample one, Sample two) but cant seem to get the correct answer. I have a webview on my XYZ view controller class. When i press on a button, it takes an URL from an array and re-loads the same webview. Now I need to do the flip book animation on it. Same webview should be reloaded. That is the webview should rotate around its own axis 180/360 degree while the loading of next url is going on. Is this possible?

  • How do I make a UIAlertView happen only on the first start-up of an iPhone app?

    - by user309245
    I'm using the UIAlertView to make a pop-up happen once the app has started up. It works fine but I only want the pop up to happen on the first start-up of the app. At the moment I've got the UIAlertView in the AppDelegate class, after the application didFinishLaunching. Here is my code at the moment. - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { sleep(4); UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Welcome!" message:@"SAMPLE!!!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert show]; [alert release]; I'm new to app development so sorry if this is simple. Thanks in advance! :)

  • displaying mac address in right format

    - by califguy
    Hi, I am obtaining the mac(hw) address of an interface using CWNetwork. Now OS X gives me this mac address in the xx:xx:xx:xx:xx:xx format. But if the first digit is 0, OS X will output the address as 4:aa:dd:ee:34:40, instead of 04:aa:dd:ee:34:40. Now I am trying to take this string 4:aa:dd:ee:34:40 and convert it to 04:aa:dd:ee:34:40 before displaying it. Any ideas ? APpreciate the help.

Here's the code I have been using: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"touchDown"); UITouch *touch = [touches anyObject]; firstTouch = [touch locationInView:self.view]; lastTouch = [touch locationInView:self.view]; [self.view setNeedsDisplay]; } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { InSightViewController *contentView = [[InSightViewController alloc] initWithNibName:@"SubView" bundle:[NSBundle mainBundle]]; [contentView loadView]; UITouch *touch = [touches anyObject]; currentTouch = [touch locationInView:self.view]; if (CGRectContainsPoint(contentView.view.bounds, firstTouch)) { NSLog(@"touch in subView/contentView"); sub.frame = CGRectMake(currentTouch.x - 50.0, currentTouch.y, 130.0, 21.0); } NSLog(@"touch moved"); lastTouch = currentTouch; [self.view setNeedsDisplay]; } And here's what's been happening: http://cl.ly/Sjx
