Answer 1

不要忘记: #Import <QuartzCore/QuartzCore.h>

工作代码:

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
    textField.layer.cornerRadius=8.0f;
    textField.layer.masksToBounds=YES;
    textField.layer.borderColor=[[UIColor redColor]CGColor];
    textField.layer.borderWidth= 1.0f;
    return YES;
}
