[SOLVED] Multiple clicks on UIButton trigger Target function multiple times

Multiple clicks on UIButton trigger Target function multiple times

I have a UIButton. I bound a target as follows.

[button addTarget:self action:@selector(myFunction) 
                forControlEvents:UIControlEventTouchUpInside];

When i click my Button multiple times quickly it invoke the target function multiple times. On Tapping button i present a new View controller. when i click 3 times quickly then my new view controller is shown 3 times.

This is something stupid. Whats the point of triggering the function again once the View has been shifted to a new View controller. Why the Hell Apple do such stupid things ?

Any Help please?

Solution

First of all its not apple bugs. It should be handle manually. So follow these step

First make your global instance of your button then do this

.h file

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

.m file

- (IBAction)myFunction:(id)sender
{
    self.btn.userInteractionEnabled = NO;
}

-(void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    self.btn.userInteractionEnabled = YES;
}
