如何在Swift中为UITextView应用阴影？

Question

我尝试为我的UITextView应用阴影，就像我为UIView所做的一样，但它没有起作用。

试试这段代码：

Obj-C

txtView.layer.cornerRadius = txtView.frame.size.height/2;
txtView.clipsToBounds = NO;
txtView.layer.shadowOpacity=0.4;
txtView.layer.shadowOffset = CGSizeMake(3, 3);

Swift

->

Swift

txtView.layer.cornerRadius = txtView.frame.size.height/2
txtView.clipsToBounds = false
txtView.layer.shadowOpacity=0.4
txtView.layer.shadowOffset = CGSizeMake(3, 3)

我希望它能为你工作。
