使用NSTimer调用performSelectorOnMainThread

Question

I am able to call pushIncompleteDataToServer in below line.

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

Now i want to call it with a NSTimer in an interval to 5.0 sec

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

instead of pushIncompleteDataToServer I want to call performSelectorOnMainThread (what in the first statement) . How to do that?

Answer 1

Do like this

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


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

}
