tableView切换频繁崩溃问题

If that is the case then you will need to override the removeFromParentViewController method of the controller and manually set the tableView property to nil. For example: -(void) removeFromParentViewController { [super removeFromParentViewController]; if(self.tableView!=nil) { self.tableView.delegate = nil; self.tableView.dataSource = nil; self.tableView = nil; } }
