AgentDashboardNavigationController LIVES！

我继续执行相同的过程，我的tabBarController中的agentDashboardNavigationController VC被编辑界面VC替换。

完成后，编辑界面将替换为新的agentDashboardNavigationController。

由于某种原因，live 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，在一个选项卡中来回翻转。

agentDashboardNavigationController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];

并将其换出：

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];

抓一点。问题是保留周期。一旦我意识到我应该在“记录引用计数”位上打勾，我可以看到它的孩子保留了它！

我的第一个。那些人很难解决。
