按钮不出现在工具栏上
一个简单的问题。如何与 TTLauncherViewController 结合添加工具栏项。我必须做一些非常基本的错误，因为工具栏出现，但按钮不显示：
self.navigationController.toolbarHidden = NO;
self.navigationController.toolbar.tintColor = [UIColor blackColor];
UIBarButtonItem *updateBttn = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh
target:self
action:@selector(updateData:)];
UIBarButtonItem *btnSpacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil ];
self.navigationController.toolbarItems = [NSArray arrayWithObjects:updateBttn, btnSpacer, nil];
[btnSpacer release];
[updateBttn release];
A simple question. How do I add toolbar items in combination with a TTLauncherViewController. I must do something very basic wrong, as the toolbar appears, but the button does not show:
self.navigationController.toolbarHidden = NO;
self.navigationController.toolbar.tintColor = [UIColor blackColor];
UIBarButtonItem *updateBttn = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh
target:self
action:@selector(updateData:)];
UIBarButtonItem *btnSpacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil ];
self.navigationController.toolbarItems = [NSArray arrayWithObjects:updateBttn, btnSpacer, nil];
[btnSpacer release];
[updateBttn release];

这可能是问题所在吗？

简而言之，它表示工具栏不是导航控制器的子级，而是导航控制器的子级。父视图。
Could this be the issue?

In short, it says that the toolbar is not a child of the navigation controller but the parent view.
