如何以编程方式在iphone中添加标签和文本框？如何为标签和文本框设置框架？

Answer 1

以下代码创建a UILabel和a UITextField,并将它们添加到视图控制器视图中.在loadView方法中或视图控制器中的某个位置添加此代码.

// 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];

您还可以使用setter方法设置其他属性.
