如何设置UITextfield的边框样式

Question

如何在程序中设置UITextField的边框样式？

我是这样创建文本字段的：

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];

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];

你可以使用Quartzcore和图层属性。

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

我必须记住将QuartzCore添加到你的项目中，并在需要使用它的地方导入它。

从以下四个选项中，任何一个都可以被程序化地使用：

[textField setBorderStyle:UITextBorderStyleNone];

[textField setBorderStyle:UITextBorderStyleLine];

[textField setBorderStyle:UITextBorderStyleBezel];

[textField setBorderStyle:UITextBorderStyleRoundedRect];

其中textField是UITextField的出口。

我知道，这个问题是关于Obj-C的，但我来这里是为了Swift。在Swift中，可以这样做：

txt.backgroundColor = UIColor(red: 0.9, green: 0.9, blue: 0.9, alpha: 1.0);
txt.borderStyle = UITextBorderStyle.RoundedRect
let myColor : UIColor = UIColor(red: 0.9, green: 0.9, blue: 0.9, alpha: 1.0);
txt.layer.borderWidth = 3;
txt.layer.borderColor = myColor.CGColor;

这将设置自定义背景颜色和边框，颜色相同（以隐藏边框但仍具有文本和文本字段边框之间的一些填充）。

[pTxtTithiTime.layer setBorderColor:[[[UIColor grayColor] colorWithAlphaComponent:0.5] CGColor]];

[pTxtTithiTime.layer setBorderWidth:0.8];

//圆角部分，您可以在此指定视图的圆角半径：

  pTxtTithiTime.layer.cornerRadius = 5;

  pTxtTithiTime.clipsToBounds = YES;

你可以像这样以编程方式创建UITextField：

UITextField *txtField = [[UITextField alloc]initWithFrame:CGRectMake(10, 260, 280, 30)]; // your required coordinate
txtField.delegate =        self;
txtField.placeholder =     @"My TextField";
txtField.borderStyle =      UITextBorderStyleNone;
txtField.keyboardType =        UIKeyboardTypeDefault;
txtField.backgroundColor =       [self setBackGroundColorOnButton];
txtField.layer.cornerRadius = 5.0;
