Question

I have an UIButton that the user must click on it 5 times in three seconds, im trying to implement a method for that, but im getting the correct result if the user clicked on the button 5 times in 3 seconds in a row, if the user clicked once and stopped for 2 seconds for example, the counter take the first click in the calculation.

in a short words, i need a method that detect the last five clicks and know if the clicks were in three second or not…

Here is my old code:

-(void)btnClicked{
 counter++;

if (totalTime <=3 && counter==5) {

        NSLog(@"My action");
        // My action
}}

I know that my code is too simple, so that why i asked you pro’s

Try altering this example appropriately:

// somewhere in the initialization - counter is an int, timedOut is a BOOL
counter = 0;
timedOut = NO;

- (void)buttonClicked:(UIButton *)btn
{
    if ((++counter >= 5) && !timedOut) {
        NSLog(@"User clicked button 5 times within 3 secs");

        // for nitpickers
        timedOut = NO;
        counter = 0;
    }
}

// ...

[NSTimer scheduledTimerWithTimeInterval:3.0
    target:self
    selector:@selector(timedOut)
    userInfo:nil
    repeats:NO
];

- (void)timedOut
{
    timedOut = YES;
}
