ios - 使用 NSTimer 调用 performSelectorOnMainThread

Question

我可以在下面的行中调用 pushIncompleteDataToServer。

[sharedDataController performSelectorOnMainThread:@selector(pushIncompleteDataToServer) 
                                       withObject:sharedDataController 
                                    waitUntilDone:NO].

现在我想用 NSTimer 以 5.0 秒的间隔调用它

[NSTimer scheduledTimerWithTimeInterval:5.0 
                                 target:sharedDataController 
                               selector:@selector(**pushIncompleteDataToServer**) 
                               userInfo:[ self userInfo] 
                                repeats:YES];

我想调用 performSelectorOnMainThread(第一条语句中的内容)，而不是 pushIncompleteDataToServer。如何做到这一点？

这样做

[NSTimer scheduledTimerWithTimeInterval:5.0 
                                 target:sharedDataController 
                               selector:@selector(pushData) 
                               userInfo:[ self userInfo] 
                                repeats:YES];


-(void)pushData {
    [sharedDataController performSelectorOnMainThread:@selector(pushIncompleteDataToServer) 
                                           withObject:sharedDataController 
                                        waitUntilDone:NO].

}
