這聽起來可能是一個新手的問題,無論如何,我很新的GCDGCD:如何更改計時器防火間距
我下面的代碼:
int interval = 2;
int leeway = 0;
dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
dispatch_source_t timer = dispatch_source_create(DISPATCH_SOURCE_TYPE_TIMER, 0, 0, queue);
if (timer) {
dispatch_source_set_timer(timer, dispatch_walltime(DISPATCH_TIME_NOW, NSEC_PER_SEC * interval), interval * NSEC_PER_SEC, leeway);
dispatch_source_set_event_handler(timer, ^{
[self someMethod];
});
dispatch_resume(timer);
}
其中的someMethod是:
- (void)someMethod
{
NSLog(@"Thread 1");
}
如何在某些方法中更改timer
的火災區間屬性?
