iOS Development diary 16-animation animation

Today Bo Master has an animation animation demand, encountered some difficulties, here and we share, hope to progress together.

There are two types of animations in iOS development: a uiview animation, also known as an implicit animation, and a change in the value of the frame after the animation. The other is Calayer animation, also known as display animation, the model layer after the animation data will not change, the graphics back to the original position. But in actual development, Because UIView can interact with the corresponding user, so UIView animation with more.

2. Property animation, transition animation
