IOS screen unlock text animation effect _ios

Cagradientlayer believe that we are more familiar with the use of it, I am not here nonsense, there are many online introduction, want to learn more about the words, you can go to see. I simply say how to use cagradientlayer to make screen unlock text animation effect.

1, create a Cagradientlayer object Gradlayer, set its frame and label.bounds the same (note here is the label of the bounds is not a frame);

2, here I give gradlayer.colors set up a total of three color values, the first color transparency set to 0.3, the middle of the color value of the transparency of the default 1.0, and then as a label mask, so that looks the effect is: the color of the end of the dark, the middle color is bright;

3, Cagradientlayer has a property locations can set the color gradient point (range is 0.0~1.0), the second color value of the gradient point set to 0.0, the animation to set it to 1.0, it will achieve the desired effect.
