Question

I’d like to know how can I make a button disable for few seconds after clicking it. I can disable it with code

button.enabled = button.enabled = NO;

But I’m not sure how it can be done for just few seconds.

Answer 1

Use this code:

double delayInSeconds = 2.0;
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, delayInSeconds * NSEC_PER_SEC);
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
    button.enabled = NO;
});

EDIT: If you want to disable your button first and execute some code later on, do this:

button.enabled = NO;
double delayInSeconds = 2.0;
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, delayInSeconds * NSEC_PER_SEC);
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
    //this will be executed after 2 seconds
});
