Hi
I have read that in explicit animation, say translation, to really change
the model layer position we have to change it's position too. So here is my
code:
CABasicAnimation *animation =
[CABasicAnimation animationWithKeyPath:@"position"];
CGPoint pt = CGPointMake(firstWheelLayer.position.x + 100,
firstWheelLayer.position.y + 100);
[animation setFromValue:[NSNumber
valueWithCGPoint:firstWheelLayer.position]];
[animation setToValue:[NSNumber valueWithCGPoint:pt]];
[animation setDuration:5.0];
[firstWheelLayer setPosition:pt];
[firstWheelLayer addAnimation:animation forKey:@"flag"];
"firstWheelLayer" is a layer with some sublayers. The above code is run as
result of touch on sublayers of "firstWheelLayer". The above code works
fine, even all sublayers translate also and if I click a sublayer after
animation , the "firstWheelLayer" further translate 100 in x and 100 in y.
I want to achieve same functionality with scaling i.e. if I scale
"firstWheelLayer" all sublayers should also scale up/down. So here is my
code:
CABasicAnimation *animation =
[CABasicAnimation animationWithKeyPath:@"bounds"];
CGRect orgVal = CGRectMake(0, 0,
firstWheelLayer.bounds.size.width, firstWheelLayer.bounds.size.height);
CGRect newVal = CGRectMake(0, 0,
firstWheelLayer.bounds.size.width+100, firstWheelLayer.bounds.size.height);
[animation setFromValue:[NSValue valueWithCGRect:orgVal]];
[animation setToValue:[NSValue valueWithCGRect:newVal]];
[animation setDuration:5.0];
[firstWheelLayer setBounds:newVal];
[firstWheelLayer addAnimation:animation forKey:@"flag"];
The problem here is that the sublayers do not scale horizontaly like the
"firstWheelLayer" should I set their bounds here too?
