如何将文本阴影应用于UITextView？ [英] How to apply text shadow to UITextView?

问题描述

其实我喜欢 UILabel 。他们很甜蜜。现在我不得不去 UITextView ，因为 UILabel 没有将文本垂直对齐到顶部。该死的。我真正需要的是文字阴影。 UILabel 有它。 UITextView 似乎没有它。但我猜那家伙只是使用相同的底层 UIKit NSString 添加？也许有人已经有解决这个问题的方法？我会覆盖什么？

Actually I love UILabel. They're sweet. Now I had to go to UITextView because UILabel is not aligning text vertically to the top. Damn. One thing I really need is a text shadow. UILabel has it. UITextView seems to not have it. But I guess that guy just uses the same underlying UIKit NSString additions?? Maybe someone already has a solution for that problem? What would I overwrite?

推荐答案

text.layer.shadowColor = [[UIColor whiteColor] CGColor];
text.layer.shadowOffset = CGSizeMake(1.0f, 1.0f);
text.layer.shadowOpacity = 1.0f;
text.layer.shadowRadius = 1.0f;

并且不要忘记加上顶部：

And don't forget to add up top:

#import <QuartzCore/QuartzCore.h>
