我如何知道用户是否单击了按钮？

Question

What is the easiest way to determine which button was clicked by the user?

What I am doing:

 if((themeSeclection.highlighted = YES)){
        informationView.text =@"This is test";
    }
    if((caputreImage.highlighted = YES)){
        informationView.text =@"This is another test";
    }
    if((switchCamera.highlighted = YES)){
        informationView.text =@"Test 3";
    }

Answer 1

You have got your buttons as IBOutlets or just locally created

UIButton *btn1;
UIButton *btn2;
UIButton *btn3;

Now you have the option to assign individual methods as actions to these buttons. However, one action would to, which may be the following:

- (IBAction)ButtonPressed:(UIButton*)sender
{
    if (sender == btn1) ...
    if (sender == btn2) ... 
    // and so on
}
