如何设置UITextfield的边框样式

Question

如何以UITextField编程方式设置边框样式？

我正在创建我的文本字段:

UITextField *tfText = [[UITextField alloc] initWithFrame:CGRectMake(65, 200, 200, 30)];
tfText.backgroundColor = [UIColor colorWithRed:0.2 green:0.9 blue:0.5 alpha:0.3];       
tfText.textAlignment = UITextAlignmentCenter;
[self.view addSubview:tfText];
[tfText release];

Answer 1

试试这个

UITextField *tfText = [[UITextField alloc] initWithFrame:CGRectMake(65, 200, 200, 30)];
tfText.backgroundColor = [UIColor colorWithRed:0.2 green:0.9 blue:0.5 alpha:0.3];       
tfText.textAlignment = UITextAlignmentCenter;
// Border Style None
[tfText setBorderStyle:UITextBorderStyleNone];
[self.view addSubview:tfText];
[tfText release];

以供参考

您可以使用Quartzcore和图层属性.

sometextfield.layer.borderWidth = 1;
sometextfield.layer.borderColor = [[UIColor redColor] CGColor];

我必须记住将QuartzCore添加到您的项目中并将其导入您想要使用它的位置.

从四岁以下,任何人都可以以编程方式使用,

[textField setBorderStyle:UITextBorderStyleNone];

[textField setBorderStyle:UITextBorderStyleLine];

[textField setBorderStyle:UITextBorderStyleBezel];

[textField setBorderStyle:UITextBorderStyleRoundedRect];

其中textField是UITextField的出口
