xcode4.4

问题 yesterday I installed Xcode 4.4. I'm working on a project which needs to run on ios 4.1 upwards, supporting iOS device with camera. Until I installed Xcode 4.4 everything went well, and I can test app on iphone 3gs and 4s. After I installed Xcode 4.4 I was unable to test app on iphone 3gs, and everytime I try to do it, xcode shows me that message: - Could not lauch "appname". timed out for app to lauch - Does someone have any idea how to get rid of that error? 回答1: I had a similar issue when

问题 When ever I run my app in Xcode 4.4 the simulator fails to open, "iOS Simulator quit unexpectedly." It runs on perfectly on the device though. 回答1: I solved by installing xcode 4.5 and ios sdk 6. Now all work fine. 回答2: You may have had a bad build on the Simulator, which is now messing things up. Clean your code (Product > Clean in XCode) Reset your simulator settings (iOS Simulator menu > Reset Content and Settings) That should do it. 回答3: I Had the same problem i just did following steps

问题 i updated my mac book to mountain lion and Xcode to the 4.4 version. In the pre version I had no problems with closing the iOS simulator and Xcode stopped automatically the building process but now if I close the iOS simulator the build process in Xcode is still running and I have to force quit Xcode because it freezes. Does anyone recognize this bug, or can you help me to solve this problem? 回答1: As a workaround, I've noticed that Running (⌘ + R) and then Bulding (⌘ + B) product succesfully

问题 I'm trying to follow the instructions in XCode - Code Coverage? and Code Coverage on Xcode 4.4.1 The .gcno files are generated in DerivedData, but I can't get it to generate the .gcda files.

问题 I have created a new folder in my project in which I have copied an image (called "io.jpg"). I also have checked on build phases -> copy bundle resources and the file is there. So I am trying to get the path of this image: NSBundle* bundle=[NSBundle mainBundle]; NSString* path=[bundle pathForResource: @"io" ofType: @"jpg"]; NSLog(@"%@",path); But it prints (null), I also have tried this way: NSBundle* bundle=[NSBundle mainBundle]; NSString* path=[bundle pathForImageResource: @"io"]; NSLog(@"%

问题 I can write @42 , which creates an NSNumber with int value 42. Can I do this with a variable, like @someIntVar ? Obviously I tried it and it doesn't work (which sucks because then I have to go through [NSNumber numberWithInt:someIntVar] ). Is it possible with a slightly different syntax? 回答1: I strongly suggest you read the official clang documentation on the matter: http://clang.llvm.org/docs/ObjectiveCLiterals.html But, to box a variable, or any expression, you can use parentheses: id num =

问题 On both Xcode 4.4 and 4.4.1 I'm experiencing the same issue in that with the specific project I'm working on, I don't seem to be able to rename any classes or variables from the Refactor menu option. Each time I try and do a rename, I type in the new name for the class/variable and click Preview at which point the bottom left begins a spinner with Finding files... . However, I then get a message saying: The selection is not a type that can be renamed. Make a different selection and try again.

问题 I have the following Xcode project dependencies: A -> C B -> C When I build these separately, everything works fine. However, I want to add A and B to the same Xcode project, creating the following dependency graph: / -> A -> C D-< \ -> B -> C This causes duplicate symbol errors, and is basically DLL hell. What is a good way to resolve this while allowing the projects to be independent? I realize that I could break up A and B 's dependency on C , and then remake that dependency in D , but I
