xcode6

问题 I have created a Cocoa application in Xcode6 which uses storyboards. As a template, Xcode provides a window for the application. I want to add a second window to show when the program is first loaded. So basically, there will be two windows showing up. I have put a window controller on Main.storyboard where the first window also resides. However, I couldn't find the way to show this second window when the program starts. Could you please help? Thank you. 回答1: In your Storyboard, select your

问题 Ok, so I am trying to submit an app for a client of ours. They have invited me to their developer program as 'Admin' and we created all of the certs, provisioning profiles, and distribution profiles. I am able to select their account when submitting also. I go to submit the app via XCode 6.0.1 and it gets all the way to authenticating with iTunes Connect, then it throws this error... ERROR ITMS-4088: "The organization "Company Name" does not have permission to modify the application with the

问题 An attempt to print object ( po command) in xcode 6 beta 6 OSX Swift project results in this error message: (lldb) po managedObject error: Error in auto-import: failed to get module '__ObjC' from AST context In this case the object in question is an instance of NSManagedObject . Any advice on how to help auto-import in getting __ObjC module into LLVM Abstract Syntax Tree context? 回答1: As of Xcode 6.1 if you attempt the po command twice it will work on the second attempt.

问题 I keep having this error I've seen other questions been answered by using textLabel.text, but it doesn't work in my case I'm new to swift so could someone please explain me why and how to solve this. 回答1: You need to unwrap textLabel by using an ! after textLabel . This is because textLabel is an Optional (hence the textLabel? type instead of just textLabel ). Read more about optionals here. Hope that helps! 来源： https://stackoverflow.com/questions/26330869/swift-text-is-unavailable-apis

问题 I'm trying to make a popup like I described in my previous question. I actually got an answer, but now I have a new problem. I can make the view appear if I don't make the instantiateWithOwner , but it is not responding to anything (just frozen). In short, I have set up a 'popup.xib' file, which is just a view with a button and a label. My code below should make it appear and disappear with button clicks. I have read the documentation that the instantiateWithOwner does all the magic of

问题 Really weird issue going on here. Using XCode6 with iOS8 I have a simple UIImageView, which moves across the screen when I click. No problem- works great. I Just have a simple method to update specific labels...based on an int called StrikesLeft. Here is my updateLabels method: -(void)displayLabels{ //update strikes label strikesLeftDisplay = [NSString stringWithFormat: @"%d", strikesLeft]; lblStrikes.text=strikesLeftDisplay; } Here is the weird issue though: If I don't actually update the

问题 I have the right code to move an object randomly and also to make numbers count down but I am not able to have an object move while the timer counts down. One thing I found weird though was that when I took out the part about the TimeLeft label the objects moved randomly but obviously the numbers did not count down. The main question is: how can I have a timer countdown and have the object move at the same time? (my main goal is to make the object stop moving once the timer reaches zero) I

问题 Has anyone been able to get the simulator in xcode 6 to use the 3x images inside of an atlas? Whenever I load them into SKTextureAtlas it will use the 2x image instead. if i put test@2x.png, and test@3x.png inside of an atlas, my iphone 6 / plus simulator will always use the 2x image. let texture = shipAtlas.textureNamed("ship") // always uses 2x image 回答1: apparently you need to have launch images set (in project settings) in order for xcode to recognize different screen sizes properly 来源：

问题 I am working on an app and would like to include iAd's. I have managed to add banner ad's and they work well. However i want to a larger add that fills most of the screen but not full screen. I added the adBanner using code from Benzene's Question and given solution from erdekhayser.
