问题 Is it possible to create a nib file that has a table view with custom static cells? I want to create a form-like table view with all static content, but I'm not currently using storyboards. I was able to find the content type menu in the default Storyboard of my app, but I'm using Nibs, and when I create either a UIViewController nib or a UITableViewController nib, in both cases there is no content type menu in the Attributes inspector tab. Any thoughts? 回答1: It seems like at the moment, what

问题 I am making a game with Sprite Kit. When there is a collision I would like to retrieve the image of the SKSpriteNode that my projectile collided with to assign different point values depending on the image of the monster.

问题 If I have an array of connected peers, let's say 3 (a->b, a->c, a->d) and I want to disconnect peer "c" only, what should I be doing? I've seen one response to a similar question state that you can only disconnect 'yourself' from a session: meaning that in the above scenario if I do this: [mySession disconnect]; that I all be disconnecting "a" from "b", "c" and "d" simultaneously. So the suggestion was to send a notification to the peer you want disconnected ("c") and tell it to disconnect

Is there a better way to adding a UIToolBar to the UINavigationBar? 回答1: You should follow this simple approach. Add a UIToolBar like this. UIBarButtonItem *flexiableItem = [

问题 After I search a lot of questions and answers, no good result. So I have to ask it here: I want to add a Search Bar below the navigation bar. This search bar should be fixed. Just like contacts on iOS7 below. Can any one help me to figure it out? 回答1: You have a view controller. It has a main view.

问题 UPDATE: I have just encountered this issue on an actual iPhone 5 running iOS 7. Will provide more information soon.
