将repeatCount设置为1e100f会发出警告
来自 Apple 文档：
Setting the repeatCount to 1e100f will cause the animation to repeat until it is removed from the layer.
这是我的代码：
CABasicAnimation *flicker = [CABasicAnimation animationWithKeyPath:@"opacity"];
flicker.repeatCount = 1e100f;
Xcode 发出警告：
Semantic Issue: Magnitude of floating-point constant too large for type 'float'; maximum is 1.7014116E+38
我做错了什么？
From Apple Documentation:
Setting the repeatCount to 1e100f will cause the animation to repeat until it is removed from the layer.
Here's my code:
CABasicAnimation *flicker = [CABasicAnimation animationWithKeyPath:@"opacity"];
flicker.repeatCount = 1e100f;
Xcode gives a warning:
Semantic Issue: Magnitude of floating-point constant too large for type 'float'; maximum is 1.7014116E+38
Something I'm doing wrong?

尝试使用 HUGE_VALF （我认为是 1e50f，但使用常量）。查找 repeatCount 告诉我们：
Try using HUGE_VALF (which I think is 1e50f, but use the constant) instead. Looking up repeatCount tells us:
更改 flicker.repeatCount = 1e100f；
到
闪烁.repeatCount = 1e100;
change flicker.repeatCount = 1e100f;
to
flicker.repeatCount = 1e100;
