Remove observer before deallocating, otherwise observer accumulate and eventually crash the application.

[[NSNotificationCenter defaultCenter] removeObserver:self];

You can not specify a structure field key path using Objective-C 2.0 properties. This will not work:

myLayer.transform.rotation.x=0;

Instead you must use setValue:forKeyPath: or valueForKeyPath: as shown below:

[myLayer setValue:[NSNumber numberWithInt:0] forKeyPath:@"transform.rotation.x"];

brrrrrr.

- (id)valueForKey:(NSString *)key

• (void)setValue:(id)value forKey:(NSString *)key

always [self release] when [self.view removeFromSuperview]

[self.view removeFromSuperview]; [self release];

... or duplicates of the view remain.

If reality and my image of it do not concur, then it's a pity for reality.

CGPoint CGPointMake ( CGFloat x, CGFloat y );

x, y has to be floats, passing only integers might not work.

especially good to know, when and if ints get converted into floats.

= CGPointMake(100.0f + someIntVar, 50.0f + anotherIntVar); ≠ CGPointMake(100 + someIntVar, 50 + anotherIntVar);

this .0f seems to have a meaning after all.

Adding Border between UIScrollView page, but keep the content pages fullscreen.

1. setting bounds defines snapping points. (myScrollView.frame) = CGRectMake(0, 0 , 320+(myPixelBorder), 480);

2. keep subview size at fullscreen width (mySubView).size.width = 320;

pagingEnabled should be set to NO, BEFORE attempting to change the offset with setContentOffset:point animated:NO.

if the order is reversed, strange results. would only work when animated:YES
