Several methods of iOS anti-repeated clicks

1. global variable flag method

@property (nonatomic,assign) boolisclickedflag;//prevent repeated clicks
#pragma mark--global variable flag method
-(void) ljbtnclicked
{
    if (Self.isclickedflag ==yes)
    {
        Self.isclickedflag =no;
        function//own function
        {
           Do what you need to do, then open click
           self.isclickedflag =yes
        }
}

2. Delay Call Method

Delay 0.5s to perform
 [selfperformselector: @selector (ljbtnclicked) withobject:nilafterdelay:0.5];

 Dispatch_after (Dispatch_time (Dispatch_time_now, int64_t) (0.5 * nsec_per_sec)),  Dispatch_get_main_queue (), ^{
                  [Self ljbtnclicked];//Delay execution
                }];

3. Class Delay method

You just need to set a property time.

4. Set the Click UI property to No (most effective method)

[_btnnode Setcontrolnodeenable:no];
 
      Dispatch_after (Dispatch_time (Dispatch_time_now, int64_t) (0.5 * nsec_per_sec)), Dispatch_get_main_queue (), ^{
                    [ Self ljbtnclicked];//delay execution
                    [_btnnode setcontrolnodeenable:yes];
                };
