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
