uinavigationcontroller

问题 First off, I am aware of this question being asked in a forward manner, but in this case I am asking for a backwards manner in which the Navigation Controller is already designed. With that being said... I have a UINavigationController with three views: Table , Get , and Avail in that order that was created in IB. When going forward, I want to go from Table to Get to Avail , but when I hit the "Back" button on Avail I want to skip over Get and go directly back to Table . Is this possible? If

问题 In my view controller I am setting the titleView to a UIView which contains a UIImageView which is made into a circle using setCornerRadius on its layer. The top half of the circle is positioned over the navbar, and the bottom half over the view, like this: Now when I push this view controller, as it animates in, the bottom half of the circle is cut off until the animation completes. Only the part that's in the navbar is shown, something like this: As soon as the push animation ends, the full

问题 I've been spending some time trying to sort out custom transition animations available in iOS 7. According to this question, UINavigationControllerDelegate is the way to go. There are, however, no examples or documentation describing how best to approach a simple vertical transition in iOS7. (There are a plethora of other transition styles using UINavigationControllerDelegate, but none as simple as sliding the view up and down -- there are others that suggest just modifying the view position,

问题 I need to build a code to track what id i use from an order view, but now i can't get it to work, can somebody paste a sample code to me? i need a TagID from view1 -> view2, so when i'm landing on view2 i can get informations about it and send to users screen. i hove on a little help here :0) 回答1: I think what you're saying here is that you are moving from one UIView to another in your application, and you need some way of "passing" a variable from view1 to view2. This is a common use-case

问题 I have an UINavigationController and the first view is an UIView. I've setup two buttons and each one pushes another view , both UITableViewControllers. The first buttons works just fine. The problem is: when I'm in the second TableViewController and I tap on the back button it tries to push the view again and only the second time it goes back to the Main View. I also have an UITabBarController setup and I noticed that if I am in my first tab(the Main View with the two buttons pushing the two

问题 I have been trying to find this issue here, but no topic seems to fit... I have a UINavigationController that pushes different kinds of UIViews containing images. When the controller pushes a new view, it the navigation bar is moved onto the screen and it appears that the image subsequently is being 'squelched' a bit - or it 'moves in from top' (I hope I described this sufficiently). Anyway, my image has the frame of 320x460 (because of the top bar). I couldnt find a proper setting, where the
