CABasicAnimation animationWithKeyPath 一些规定的值

CABasicAnimation   animationWithKeyPath   Types

When using the ‘CABasicAnimation’ from the QuartzCore Framework in Objective-C, you have to specify an animationWithKeyPath.  This is a long string and is not easily listed in the CABasicAnimation, CAPropertyAnimation, or the CAAnimation class.  I ended up finding a handy chart within the Core Animation Programming guide in Apple’s iPhone OS Reference Library.  Hope this helps save someone time, at least it will for me.
