GCDTimer

Timer which use GCD to implementation. It is an elegant way to use GCD to implement a Timer, more easier, we could't care about the NSTimer's usage in different thread.

Usage

• import GCDTimer.h GCDTimer.m file to your project.
• import GCDTimer.h to the file which you wants to use, and invoke like this.

    _timer =  [GCDTimer scheduleTimerWithInterval:1 repeats:YES isMainQueue:NO block:^{
        NSLog(@"testViewController globalQueue executed");
    }];

NOTE: when repeats = YES, you must invoke the method - (void)invalidate; to release the GCDTimer instance.

API
