如何以编程方式设置UITextField的边框样式？

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];

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。

从四岁开始，任何人都可以通过编程方式使用，

[textField setBorderStyle:UITextBorderStyleNone];

[textField setBorderStyle:UITextBorderStyleLine];

[textField setBorderStyle:UITextBorderStyleBezel];

[textField setBorderStyle:UITextBorderStyleRoundedRect];

其中 textField 是 TextField 的出口

Answer 4

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

[pTxtTithiTime.layer setBorderWidth:0.8];

//圆角部分，您可以在其中指定视角的半径：

  pTxtTithiTime.layer.cornerRadius = 5;

  pTxtTithiTime.clipsToBounds = YES;

Answer 5

我知道，问题是关于Obj-C，但是我来到斯威夫特。在Swift中，它就是这样做的：

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;

这会设置自定义背景颜色和相同颜色的边框（隐藏边框，但文本和文本字段边框之间仍有一些填充。

您可以像这样以编程方式制作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;
