最近在做一個功能觀看密碼的功能

關於UITextField 右邊多一個按鈕 直接上圖

程式

BOOL isSecurePass;

// Only override drawRect: if you perform custom drawing.

// An empty implementation adversely affects performance during animation.

- (void)drawRect:(CGRect)rect {

// Drawing code

self.secureTextEntry = YES;

self.clearButtonMode = UITextFieldViewModeNever;

UIButton *Button_ShowPassword = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 20, 20)];

    [Button_ShowPassword setImage:[UIImage imageNamed:@"eye"] forState:UIControlStateNormal];

isSecurePass = YES;//預設密碼不顯示

//顯示密碼

    [Button_ShowPassword setAction:@"TouchInside" withBlock:^(UIButton *response) {

isSecurePass = !isSecurePass;

self.secureTextEntry = isSecurePass;

    }];

self.rightView = Button_ShowPassword;

self.rightViewMode = UITextFieldViewModeAlways;

}

- (CGRect) rightViewRectForBounds:(CGRect)bounds {

CGRect textRect = [super rightViewRectForBounds:bounds];

    textRect.origin.x -= 10;

return textRect;

}
