如何设置标签和文本框的边框？

以下代码创建一个

UILabel

和一个

UITextField

，并将它们添加到视图控制器视图中。将此代码添加到

loadView

方法中或视图控制器中的某个位置

// Create Label
UILabel *myLabel = [[UILabel alloc]initWithFrame:CGRectMake(10, 50, 200, 40)];
[myLabel setBackgroundColor:[UIColor clearColor]];
[myLabel setText:@"Hi Label"];
[[self view] addSubview:myLabel];
[myLabel release];

// Create Text Field
UITextField *myTextField = [[UITextField alloc] initWithFrame:CGRectMake(10, 100, 200, 40)];
[myTextField setBackgroundColor:[UIColor clearColor]];
[myTextField setText:@"Hi Text Field"];
[[self view] addSubview:myTextField];
[myTextField release];

还可以使用setter方法设置其他属性

UITextField *textField = [[UITextField alloc]initWithFrame:CGRectMake(10, 10, 29, 40)];
[textField setBorderStyle:UITextBorderStyleRoundedRect];
[self.view addSubview:textField];

UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(10, 10, 29, 40)];
label.text = @"Custom Label";
[label setFont:[UIFont boldSystemFontOfSize:16]];
[self.view addSubview:m_label];
