CATransform3D scale3 = CATransform3DMakeScale(0.9, 0.9, 1);
CATransform3D scale4 = CATransform3DMakeScale(1.0, 1.0, 1);
NSArray *frameValues = [NSArray arrayWithObjects:
[NSValue valueWithCATransform3D:scale1],
[NSValue valueWithCATransform3D:scale2],
[NSValue valueWithCATransform3D:scale3],
[NSValue valueWithCATransform3D:scale4],
nil];
[animation setValues:frameValues];
NSArray *frameTimes = [NSArray arrayWithObjects:
[NSNumber numberWithFloat:0.0],
[NSNumber numberWithFloat:0.5],
[NSNumber numberWithFloat:0.9],
