如何更改按钮的背景颜色？

Question

按下时如何更改按钮的背景颜色？

@property (weak, nonatomic) IBOutlet UIButton *buttonDeleteOutlet;

我的按钮没有方法： setBackgroundColor（UIColor *）forState：（UIControlState *）。只有 setBackgroundColor：（UIColor *）。

  

'UIButton'没有可见的@interface声明选择器   'setBackgroundColor：forState：

为什么？

Answer 1

你也可以尝试这个

  (a) I think there is no method like setBackgroundColor: forState: in iOS 6 or iOS 7. So you have to put background color images using below methods

    [btn setBackgroundImage:[UIImage imageNamed:@"yourRedButton.png"] forState:UIControlStateHighlighted];
    [btn setBackgroundImage:[UIImage imageNamed:@"yourBlueButton.png"] forState:UIControlStateNormal];

 (b) Using Tint Color

    [YourButton setTintColor:[UIColor color]];

Answer 2

您需要为正常和突出显示的状态设置按钮的颜色，例如

[yourButtonName setBackgroundColor:[UIColor redColor] forState:UIControlStateNormal];
[yourButtonName setBackgroundColor:[UIColor blueColor] forState:UIControlStateHighlighted];

Answer 3

[myButton setBackgroundColor:[UIColor blackColor] forState:UIControlStateNormal];

点击状态时

：

[myButton setBackgroundColor:[UIColor blackColor] forState:UIControlStateHighlighted];
[myButton setBackgroundColor:[UIColor blackColor] forState:UIControlStateSelected];
