Import <code>QuartzCore</code> framework in you class:

<pre><code>#import &lt;QuartzCore/QuartzCore.h&gt;
</code></pre>

and for changing the border color use the following code snippet (I'm setting it to redColor),

<pre><code> textField.layer.cornerRadius=8.0f;
 textField.layer.masksToBounds=YES;
 textField.layer.borderColor=[[UIColor redColor]CGColor];
 textField.layer.borderWidth= 1.0f;
</code></pre>

For reverting back to the original layout just set border color to clear color,

<pre><code> serverField.layer.borderColor=[[UIColor clearColor]CGColor];
</code></pre>

in swift code

<pre><code> textField.layer.borderWidth = 1
 textField.layer.borderColor = UIColor.whiteColor().CGColor
</code></pre>

this question shows up pretty high on a Google search and worked for the most part! I did find that Salman Zaidi's answer was partially correct for iOS 7.

You need to make a modification to the "reverting" code. I found that the following for reverting worked perfectly:

<pre><code>textField.layer.cornerRadius = 0.0f;
textField.layer.masksToBounds = YES;
textField.layer.borderColor = [[UIColor blackColor] CGColor];
textField.layer.borderWidth = 0.0f;
</code></pre>

I understand that this is most likely due to changes in iOS 7.

 self.TextField.layer.borderWidth= 1.0f;

I have really great wish to set my own color to UITextField border. But so far I could find out how to change the border line style only.

I've used background property to set background color in such way:

<pre><code>self.textField.backgroundColor = textFieldColor;
</code></pre>

But I have to change color of UITextField border too. And my question was about how to change the border color.

UITextField border color

我真的很希望为UITextField边框设置我自己的颜色。但到目前为止，我只能知道如何改变边框线的样式。我使用了background属性来设置背景颜色，如下所示：self.textField.backgroundColor = textFieldColor;但我也必须改变UITextField边框的颜色。我的问题是如何...
