使用UITextBorderStyleNone为UITextField设置填充 [英] Set padding for UITextField with UITextBorderStyleNone

问题描述

我想为我的 UITextFields 使用自定义背景。这工作正常，除了我必须使用 UITextBorderStyleNone 使它看起来很漂亮。这会强制文本粘在左边而不进行任何填充。

I wanted to use a custom background for my UITextFields. This works fine except for the fact that I have to use UITextBorderStyleNone to make it look pretty. This forces the text to stick to the left without any padding.

我可以手动设置填充，使其看起来类似于 UITextBorderStyleRoundedRect 除了使用我的自定义背景图像？

Can I set a padding manually so that it looks similar to UITextBorderStyleRoundedRect except for using my custom background image?

推荐答案

我发现了一个简洁的小黑客为此设置左边的填充确切的情况。

I found a neat little hack to set the left padding for this exact situation.

基本上，你将 UITextField 的leftView属性设置为填充大小的空视图想要：

Basically, you set the leftView property of the UITextField to be an empty view of the size of the padding you want:

UIView *paddingView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 5, 20)];
textField.leftView = paddingView;
textField.leftViewMode = UITextFieldViewModeAlways;

对我来说就像魅力一样！

Worked like a charm for me!

在 Swift 3 中，可以通过这样做来实现

In Swift 3, it can be done by doing that

let paddingView: UIView = UIView(frame: CGRect(x: 0, y: 0, width: 5, height: 20))
textField.leftView = paddingView
textField.leftViewMode = .always
