###一个内置波浪动画的UIView。 ####A view with water wave animation inside.

##Usage

You can use code or xib to create; Then set the properties;

@property (nonatomic,assign)CGFloat waveSpeed;     // 控制波浪的快慢 the speed of the wave
@property (nonatomic,assign)CGFloat waveAmplitude; // 波浪的震荡幅度 the amplitude  of the wave

Most importantly, do not forget to call [waterView wave];

When you need to stop the wave,just call [waterView stop];
