UIDevice Orientation

Question

I have the following code in a method. When I run this in the simulator the debugger skips right over the code?? What am I missing?

if (([[UIDevice currentDe         


        

Answer 1

I recommend you to use my highlighted code instead of yours to safe some code of lines.

-(void) viewDidLoad
{
    [super viewDidLoad];
    [self rotations];
}

-(void)rotations
{
    [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
    [[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(orientationChanged:)
                                         name:UIDeviceOrientationDidChangeNotification
                                         object:nil];
}

-(void) orientationChanged:(NSNotification *)notification
{
    //USE THIS PART
    //USE THIS PART
    //USE THIS PART
    //USE THIS PART
    //USE THIS PART
    if (UIDeviceOrientationIsPortrait([UIDevice currentDevice].orientation))
    {
    }
}

INSTEAD OF

if([[UIDevice currentDevice] orientation] == UIInterfaceOrientationPortrait || 
   [[UIDevice currentDevice] orientation] == UIInterfaceOrientationPortraitUpsideDown) 
{
}

Another way of doing this without turning on orientation notification would be to

Step 1: Save the current orientation in a local variable myCurrentOrientation and assign it like this:

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
                                duration:(NSTimeInterval)duration
{
    myCurrentOrientation = toInterfaceOrientation;
}

Step 2: Use myCurrentOrientation for your check

if (UIInterfaceOrientationIsLandscape(myCurrentOrientation) == YES) {
    // landscape
}
else {
    // portrait.
}
