是否可以覆盖UITextField启用/禁用状态目标C.

Question

我有自定义UITextField类别，用于为整个应用程序自定义UITextField外观。但有时我需要禁用字段语句，并使用自定义设计看起来灰暗。

 Like to have custom [_myUITextfield setDisabled];

并且setDisabled具有

 enabled = NO;
 backgroundColor = [UIColor lightGrayColor];
 textColor = [UIColor grayColor];

我尝试添加类方法，但无法访问自己。

我现在所拥有的是定制设计：

CutomTextField.h

@interface CustomTextField : UITextField
@end

CutomTextField.m

@implementation CustomTextField

- (instancetype)initWithCoder:(NSCoder *)coder
{
    self = [super initWithCoder:coder];
    if (self) {

        self.borderStyle = UITextBorderStyleNone;
        [self.layer setBackgroundColor:[[UIColor whiteColor] CGColor]];
        [self.layer setBorderColor: [[UIColor colorWithRed:180/255.0 green:180/255.0 blue:180/255.0 alpha:1.0] CGColor]];
        [self.layer setBorderWidth: 0.0];

        [self.layer setShadowOpacity:1.0];
        [self.layer setShadowColor:[[UIColor colorWithRed:122/255.0 green:122/255.0 blue:122/255.0 alpha:1.0] CGColor]];
        [self.layer setShadowRadius:1.0];
        [self.layer setShadowOffset:CGSizeMake(0, 1)];
        self.layer.masksToBounds = NO;

        UIView *paddingView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 10, 20)];
        self.leftView = paddingView;
        self.leftViewMode = UITextFieldViewModeAlways;
    }
    return self;
}

@end

谢谢！
