Memory leak issue in navigation controller

问题:

I am doing memory leak testing. The tool indicates a leak in line 2 of the code below. What is the reason?

DailySales *ds = [[DailySales alloc] initWithNibName:@"DailySales" bundle:nil];
[self.navigationController pushViewController:ds animated:YES];
[ds release];

回答1:

The code looks fine. Are you running in the simulator or on the device? Running Instruments on the simulator can produce false leak reports.

Objects loaded from the NIB are leaking. Check your outlets and see if they are carefully released in dealloc.
