UITextField仅顶部和底部边框 [英] UITextField Only Top And Bottom Border

问题描述

我目前有常规边境.我想仅具有顶部和底部边框.

I currently have a regular border. I would like to only have a top and bottom border.

我如何做到这一点?

使用UITextField的layer属性，我有以下代码:

Using the UITextField's layer property, I have the following code:

    self.layer.borderColor = [[UIColor colorWithRed:160/255.0f green:160/255.0f blue:160/255.0f alpha:1.0f] CGColor];
    self.layer.borderWidth = 4.0f;

通过使 UITextField变长，我可以使它工作，以便用户看不到左右边框，但是我只是想知道是否有更好，更少的边框骇人听闻的方法吗?

I have kind of got it to work by making my UITextField extra long, so that the user does not see the left and right borders, but I was just wondering if there was a better, less hackish way of doing this?

我已经检查了文档，并且更改UITextField的borderStyle没有此选项.

I have checked the docs, and changing a UITextField's borderStyle does not have this option.

推荐答案

我发现一种行之有效的方法是使用图层.这是一个片段:

One approach I have found works good is using layers. Here's a snippet:

CALayer *bottomBorder = [CALayer layer];
bottomBorder.frame = CGRectMake(0.0f, self.frame.size.height - 1, self.frame.size.width, 1.0f);
bottomBorder.backgroundColor = [UIColor blackColor].CGColor;
[myTextField.layer addSublayer:bottomBorder];

希望这对某人有帮助.
