我想更改UITextField边框颜色.是否可以自定义边框的颜色？我搜索了所有选项,xib但我没有找到任何改变的选项border color.

Answer 1

你可以用这个:

yourTextField.layer.borderColor=[[UIColor blackColor]CGColor];

yourTextField.layer.borderWidth=1.0;

并记得#import <QuartzCore/QuartzCore.h>在.h文件中导入

您还可以指定RGB值.

yourTextField.layer.borderColor=[[UIColor colorWithRed:178.0f/255.0f green:178.0f/255.0f blue:178.0f/255.0f alpha:1.0] CGColor];

注意:您需要设置从iOS 7开始的两个值

更新swift 2.3

yourTextField.layer.borderColor = UIColor.blackColor().CGColor
yourTextField.layer.borderWidth = 1.0

要么

yourTextField.layer.borderColor = UIColor(red: 178.0 / 255.0, green: 178.0 / 255.0, blue: 178.0 / 255.0, alpha: 1.0).CGColor

更新swift 3.1.1

yourTextField.layer.borderColor = UIColor.black.cgColor
yourTextField.layer.borderWidth = 1.0

要么

yourTextField.layer.borderColor = UIColor(red: 178.0 / 255.0, green: 178.0 / 255.0, blue: 178.0 / 255.0, alpha: 1.0).cgColor

Answer 2

#import <QuartzCore/QuartzCore.h>

使用下面的代码更改Textfield的边框颜色

textField.layer.borderWidth = 2.0f;
textField.layer.borderColor = [[UIColor redColor] CGColor];
textField.layer.cornerRadius = 5;
textField.clipsToBounds      = YES;

对于SWIFT:

textField.layer.borderColor = UIColor.redColor().CGColor;

Answer 3

使用Quartzcore框架.您可以设置textField.layer.borderWidth以及borderColor:

tField.layer.borderColor = [UIColor redColor].CGColor;
