AgentDashboardNavigationController LIVES！

我一直在通过相同的过程，通过编辑界面VC替换tabBarController中的agentDashboardNavigationController VC。

完成后，编辑界面被替换为新的agentDashboardNavigationController。

由于某种原因，活动agentDashboardNavigationController对象的数量不断增加。

基本上，我通过替换视图控制器的可变副本中的对象，来回翻看那一个选项卡中生活的内容。

agentDashboardNavigationController在交换：

NSMutableArray *newViewControllers = [self.mainTabBarController.viewControllers mutableCopy]; 
AgentDashboardNavigationController *agentDashboardNavigationController = [[AgentDashboardNavigationController alloc] init]; 
// cycle through until we find the agentcontroller and remove it 
// for now that's the only controller that gets removed so we break 
NSUInteger index = [newViewControllers indexOfObjectPassingTest:^BOOL (id obj, NSUInteger idx, BOOL *stop) { 
    return [[obj tabBarItem].title isEqualToString:@"Guest Card"]; 
}]; 

[newViewControllers replaceObjectAtIndex:index withObject:agentDashboardNavigationController]; 
[self.mainTabBarController setViewControllers:newViewControllers animated:NO]; 

[newViewControllers release]; 

[agentDashboardNavigationController release]; 

其换出：

UISplitViewController *splitVC = self.guestCardManagementController.splitViewController; 

// remove agentTab 
NSMutableArray *newViewControllers = [self.mainTabBarController.viewControllers mutableCopy]; 

// cycle through until we find the agentcontroller and remove it 
NSUInteger index = [newViewControllers indexOfObjectPassingTest:^BOOL (id obj, NSUInteger idx, BOOL *stop) { 
    return [obj class] == [AgentDashboardNavigationController class]; 
}]; 
[newViewControllers replaceObjectAtIndex:index withObject:splitVC]; 
[self.mainTabBarController setViewControllers:newViewControllers animated:NO]; 
[newViewControllers release];

换个说法。问题是一个保留周期。一旦我意识到我应该在“记录参考计数”上打勾，我可以看到它的孩子正在保留它！

我的第一个。那些人很难解决。
