如何将UITextview设置为喜欢Rounded Rect文本字段？ [英] How to style UITextview to like Rounded Rect text field?

问题描述

我正在使用文本视图作为评论作曲家。

I am using a text view as a comment composer.

在属性检查器中，我找不到任何类似边框样式的属性，以便我可以使用圆角矩形，类似于 UITextField 。

In the properties inspector I can't find anything like a border style property so that I can make use a rounded rect, something like UITextField.

所以，问题是：我如何设置<$ c的样式$ c> UITextView 像 UITextField ，带有舍入的矩形？

So, the question is: How can I style a UITextView like a UITextField with a rounded rect?

推荐答案

您不必选择隐式样式，它涉及使用 QuartzCore 框架编写一些代码：

There is no implicit style that you have to choose, it involves writing a bit of code using the QuartzCore framework:

//first, you
#import <QuartzCore/QuartzCore.h>

//.....

//Here I add a UITextView in code, it will work if it's added in IB too
UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(50, 220, 200, 100)];

//To make the border look very close to a UITextField
[textView.layer setBorderColor:[[[UIColor grayColor] colorWithAlphaComponent:0.5] CGColor]];
[textView.layer setBorderWidth:2.0];

//The rounded corner part, where you specify your view's corner radius:
textView.layer.cornerRadius = 5;
textView.clipsToBounds = YES;

它仅适用于OS 3.0及更高版本，但我想现在它仍然是事实上的平台。

It only works on OS 3.0 and above, but I guess now it's the de facto platform anyway.
