PO"Incorrect" frame / window size after re-orientation in iPhone
text
Body
copied!<p>In my iPhone OS application I want (need) to watch for changes in the device orientation in order to rearrange certain portions of the screen. The approach I used was to use <code>CGRect frame = [UIScreen mainScreen].applicationFrame</code> to get the screen size, and from there calculate the size and / or positioning of other controls (I also tried <code>self.view.frame</code>).</p> <p>All testing was done so far in Portrait mode, so I could focus on programming the main features and later on just do some adjustments for Landscape. And here enters the problem: In <code>-(void) didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation</code> I added some logging to check the sizes before proceeding, but apparently the values for Width and Height are "wrong" (I say "wrong" because at a first glance the values does not make sense to me). </p> <p>Here's the output of some logging:</p> <ul> <li>Rotation: Landscape [w=300.000000, h=480.000000]</li> <li>Rotation: Portrait [w=320.000000, h=460.000000]</li> </ul> <p>The values for "w" and "h" in Landscape seem inverted to me - I was expecting that w=480 and h=300. </p> <p>What am I doing wrong? The code I used to debug is below. </p> <pre><code>-(void) didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation { CGRect frame = [UIScreen mainScreen].applicationFrame; CGSize size = frame.size; NSLog(@"%@", [NSString stringWithFormat:@"Rotation: %s [w=%f, h=%f]", UIInterfaceOrientationIsPortrait(self.interfaceOrientation) ? "Portrait" : "Landscape", size.width, size.height]); } </code></pre>
