无论如何,这听起来可能是一个新手问题,我对GCD很新。
我已经关注了代码:
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someMethod是:
- (void)someMethod
{
NSLog(@"Thread 1");
}
如何更改someMethod中的timer
火力间隔属性?
答案 0 :(得分:9)
我自己得到答案,用新的间隔值调用dispatch_source_set_timer
就足够了
