Question

Is the code below correct? When the user rotates the device, two labels are supposed to go to the coordinates given below. It works when the user starts the app in portrait mode, the labels are placed correctly. However, when the user starts in landscape mode, the labels DO NOT get placed correctly. But if you rotate the view to portrait and then back to landscape, they align properly. I’ve tried placing the landscape coordinates in viewDidLoad, and it still doesn’t work. What should I do? Thanks for your help!

The two labels are recordingTimeLabel and recordingTimeLabelMinutes.

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {

 if (toInterfaceOrientation == UIInterfaceOrientationLandscapeRight || toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft) {
     //is landscape

     backGround.frame = CGRectMake(0, 0, 768, 1024);

     recordingTimeLabel.center = CGPointMake(967, 22);
     recordingTimeLabelMinutes.center = CGPointMake(901, 22);

     NSLog(@"is landscape");

     //  fixedSpace.width = 400;

 } else {
     //is portrait

     backGround.frame = CGRectMake(0, 0, 1024, 768);

     recordingTimeLabel.center = CGPointMake(710, 22);
     recordingTimeLabelMinutes.center = CGPointMake(661, 22);

     NSLog(@"is portrait");

 }



}

Additionally, this code doesn’t work either:

-(void)viewWillAppear:(BOOL)animated {        
if (([[UIDevice currentDevice] orientation] == UIInterfaceOrientationLandscapeRight) || ([[UIDevice currentDevice] orientation] == UIInterfaceOrientationLandscapeLeft)) {
    //is landscape

    backGround.frame = CGRectMake(0, 0, 768, 1024);

    recordingTimeLabel.center = CGPointMake(967, 22);
    recordingTimeLabelMinutes.center = CGPointMake(901, 22);

    NSLog(@"is landscape");

} else {
    //is portrait

    backGround.frame = CGRectMake(0, 0, 1024, 768);

    recordingTimeLabel.center = CGPointMake(710, 22);
    recordingTimeLabelMinutes.center = CGPointMake(661, 22);

    NSLog(@"is portrait");

}

}

Answer 1

Got it. I used an NSTimer and called a function very often that contained this code:

-(void)updateLabelLocation {

    if (([[UIDevice currentDevice] orientation] == UIInterfaceOrientationLandscapeRight) || ([[UIDevice currentDevice] orientation] == UIInterfaceOrientationLandscapeLeft)) {

    recordingTimeLabel.center = CGPointMake(710, 22);
    recordingTimeLabelMinutes.center = CGPointMake(661, 22);

    } 

}
