iOS realizes the function of selecting button click and selecting toggle

Actually, there is nothing to remember about this. The initialization button sets the selected image and the selected image for the button respectively. Add a method to the button. It is OK to implement three sentences in the method. Let’s look at the code directly:

First declare a button in .m

 @property (nonatomic, strong) UIButton *selecBtn;

//Initialize buttonUIButton * button = [UIButton buttonWithType:UIButtonTypeCustom];
//Set pictures for buttons[button setBackgroundImage:[UIImage imageNamed:imageArray[i]] forState:UIControlStateNormal];
[button setBackgroundImage:[UIImage imageNamed:SeleimageArray[i]] forState:UIControlStateDisabled];
      //Add method[button addTarget:self action:@selector(changeDataButton:) forControlEvents:UIControlEventTouchDown];

Then in the method as follows:

 - (IBAction)btnClick:(UIButton *)btn {
   = YES;
   = NO;
   = btn;
  }

The above is the iOS button click-to-click and selected switching function introduced by the editor. I hope it will be helpful to everyone. If you have any questions, please leave me a message and the editor will reply to everyone in time. Thank you very much for your support for my website!
