Change animation time for properties of a CALayer?

It's more or less simple. You have an ivar CALayer *yourLayer. Then you set the delegate and implement the delegate method (id)actionForLayer:forKey: (void)awakeFromNib { yourLayer.

Delegate = self; yourLayer. Name = @"yourLayer"; } - (id )actionForLayer:(CALayer *)layer forKey:(NSString *)event { if(layer. Name isEqualToString yourLayer.Name) { // Check for right layer CABasicAnimation *ani = CABasicAnimation animationWithKeyPath:event; // Default Animation for 'event' ani.

Duration = .5; // Your custom animation duration return ani; } else return nil; // Default Animation }.

It's more or less simple. You have an ivar CALayer *yourLayer. Then you set the delegate and implement the delegate method -(id)actionForLayer:forKey: - (void)awakeFromNib { yourLayer.

Delegate = self; yourLayer. Name = @"yourLayer"; } - (id )actionForLayer:(CALayer *)layer forKey:(NSString *)event { if(layer. Name isEqualToString yourLayer.Name) { // Check for right layer CABasicAnimation *ani = CABasicAnimation animationWithKeyPath:event; // Default Animation for 'event' ani.

Duration = .5; // Your custom animation duration return ani; } else return nil; // Default Animation }.

A different way to do this: CATransaction begin; CATransaction setValue:NSNumber numberWithFloat:2.5f forKey:kCATransactionAnimationDuration; //Perform CALayer actions, such as changing the layer contents, position, whatever. ACALayerObject. Contents = self newCALayerContents; CATransaction commit; That code would animate the change of the CALayer's contents over 2.5 seconds.

You can also use this to disable all animations completely. Like this: CATransaction setValue:(id)kCFBooleanTrue forKey:kCATransactionDisableActions.

FYI: You can just call: CATransaction setAnimationDuration:durationSecs in -layoutSublayers or anywhere else you modify the layers and expect them to implicitly animate. This will effect the current implicit transaction and any transaction within the current one.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
