uinavigationitem

One behavior I observed in iOS 7 is that the title of the backBarButtonItem of a UINavigationItem get's renamed if the title of the currently displayed view controller is too long. Too lazy to explain so here are some photos: As you can see, when the title is too long, the back button gets renamed to "Back" regardless of what it was previously. If the title is even longer, the back button doesn't show any text, just the left arrow image. Does anyone know how to disable this behavior? I would like the back button to stay exactly what I want it to be and not get renamed. Thanks EDIT I created a

I can add a titleView to my navigationItem very easily in code: UIImageView *navImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"nav_logo"]]; UIView *titleView = [[UIView alloc] initWithFrame:navImageView.frame]; [titleView addSubview:navImageView]; self.navigationItem.titleView = titleView; However, I'm trying to do this within my storyboard, and am failing miserably. Here's what I've done: Drag and drop a UIView on top of my VC's Navigation Item. Drag and drop a UIImageView on top of the UIView Add width/height/leading/top constraints Set the image property of the

My App has 2 tabs ( tabA and tabB ), based on location the I set the navigationItem.titleView of tabB to a UIImageView when - viewWillAppear: is called. The default behaviour of tabB is to simply display a title, e.g: The issue is when the location changes and I remove the UIImageView navigationItem.titleView (using - removeFromSuperview ), the default title has also disappeared and trying to set it with: self.navigationItem.title = @"TITLE"; Does not work. Any ideas on how to solve this? Simply setting: navigationItem.titleView = nil; Will restore the text title. 来源： https://stackoverflow.com

I've create a UISegmentedControl and successfully attached it to my navigationItem.tableView. But when I try instead to attach it to a UIToolbar, it blows up. I'm sure I've seen UISegementedControls on toolbars before - but can't seem to get it working. Thoughts? // works NSArray *statusItems = [[NSArray alloc] initWithObjects:@"one", @"two", nil]; statusSegments_ = [[UISegmentedControl alloc] initWithItems:statusItems]; self.navigationItem.titleView = statusSegments_; // doesn't work NSArray *statusItems = [[NSArray alloc] initWithObjects:@"one", @"two", nil]; statusSegments_ = [

I added my left navigation bar button using the storyboard. but I want it to hide when I first load the screen. And then in response to something else, I want it to show. The navigation bar has a method for hiding the back button. But there is no method for hiding/showing the left button. Is there a simple way for doing this? Or do I have to use two methods: the hiding method creates an empty button and the showing method creates the correct button? The button in question is just the Add template that iOS provides (which makes it easy to just use the one in the storyboard than to create my own

I've been wandering how to hide / remove / disable only the main or first navigation bar in the navigation controller so that I could put an image as a whole background screen but I couldn't find any solution. Did try hide the titleview in viewdidLoad of the main navigation controller but didn't work. Tried using navigationBarHidden but it hides the whole navigation bar for the next stack of controller. So, I'm not sure how to do this. To give you an example, I would like to have something like this app - The Masters Golf Tournament - http://appshopper.com/sports/the-masters-golf-tournament .

I'm using UINavigationItem's titleView property to set a custom UILabel with my desired font size/color. Here's my code: self.headerLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 0.0, 400.0, 44.0)]; self.headerLabel.textAlignment = UITextAlignmentCenter; self.headerLabel.backgroundColor = [UIColor clearColor]; self.headerLabel.font = [UIFont boldSystemFontOfSize:20.0]; self.headerLabel.textColor = [UIColor colorWithRed:0.259 green:0.280 blue:0.312 alpha:1.0]; self.navigationItem.titleView = self.headerLabel; In the navigation bar I also have a left bar button. The result is this: alt
