you won't be able to change only one side border color unless you subclass and know you way around in draw rect method of UIView.
除非您子类化并了解 UIView 的 draw rect 方法，否则您将无法仅更改一侧边框颜色。
You should try @stiles way ..making a image and then setting it as background...
您应该尝试@stiles 方式..制作图像，然后将其设置为背景...
Steps are : Make four images ; each with a different side as a color border you want. Then change the text field background to the appropriate one.
步骤是： 制作四个图像；每个都有不同的一面作为您想要的颜色边框。然后将文本字段背景更改为适当的背景。
You should make the images as similar as to original text field ..this way you can achieve what your want,
您应该使图像与原始文本字段相似..这样您就可以实现您想要的，

You can do it using an image.
您可以使用图像来完成。
myTextField.background = [UIImage imageNamed:@"blue-line.png"];
myTextField.background = [UIImage imageNamed:@"blue-line.png"];
