xcode UILabel文本添加外部发光效果 [英] xcode UILabel text add outer glow effect

问题描述

如何为UILabel的文本添加外发光效果。我尝试使用layer.shadow ...属性，但它们实际上只是一个阴影。

How would I add an outer glow effect to a text of a UILabel. I tried to use the layer.shadow... properties but they are really just for a drop shadow.

_count.backgroundColor = [UIColor clearColor];
_count.layer.masksToBounds = NO;
_count.layer.shadowOpacity = .8;
_count.layer.shadowRadius = 5.0;
_count.layer.shadowColor = [UIColor whiteColor].CGColor;
_count.layer.shadowOffset = CGSizeMake(0.0, 0.0);

谢谢

推荐答案

所以我确定没有办法在文本上加上这种效果，有方法可以像问题中提到的那样进行内部发光或阴影投影，但是（我可以找到）没有办法添加外部发光到文本。我最终在文本后面添加了png，以完成类似的效果（但并不是我想要的效果）。

So I determined there was no way to put this kind effect on text there are ways to do an inner glow or a drop shadow as mentioned in the question but no way (that I can find) to add an outer glow to text. I ended up adding a png behind the text to complete a similar (yet not exactly what I was looking for) effect.
