xcode4

问题 Trying desperately to customize Xcode 4 keybindings. I'm editing the user .idekeybindings file (which xcode sometimes wipes out when modified while open and then subsequently attempting to update through the key bindings interface - lovely) My understanding is that providing an of s commands (selectors) instead of just a single string should execute all those commands. <key>Text Key Bindings</key> <dict> <key>Key Bindings</key> <dict> <key>@L</key> <string>selectLine:</string> <key>@d</key>

问题 I can't find anything workspace related in the Xcode Build Setting Reference. Essentially I need something like $(WORKSPACE_DIR). If Xcode doesn't provide it, is there any way to define a custom user variable that could somehow accurately provide the workspace path in the event that the working workspace were to move (think branches etc)? 回答1: Custom variables can be defined under build settings. I think there is a button named Add Build Setting. So, a new variable workspace root can be

问题 In Xcode 4.2 when I create a new branch and open it, the iOS scheme which exists in the Master is lost. Instead I have a scheme for 'Mac 64 bit." This has happened a few times in a row and I handle it by creating a new scheme, deleting the 'Mac 64 bit' one and then renaming the new scheme to what the original was. I'd rather fix whatever is wrong though. Did I set something up wrong - some preference somewhere? 回答1: I know this is old question but there doesn't seem to be a good question

问题 In Xcode 4 is it possible to somehow setup so that with one click of the 'Run' button in the top left have Xcode build to more than one device with one click? It would save a lot of time, constantly having to click build to iPhone, then build to iPod, then iPad is irritating one after another. All in one click would be ideal. An example of how this would be helpful is when building a universal app, where I want to quickly build and run on both my iPhone and iPad at the same time. Any help

问题 I'm trying to add Core Data to an existing project. I've: 1)added the Core Data framework 2)added the accessors and properties to the AppDelegate 3)created the data model file Now when I try to call NSManagedObjectContext *context = [self managedObjectContext]; from a view controller the context is nil and the managedObjectContext never fires.

问题 I use XCode for one year, and I made a user script in Python. This script gets the all document, gets the cursor position thanks to %%%{PBXSelectionStart}%%%, does some very useful stuff, and replaces all the current document, without moving the cursor. It works fine. But I upgraded to XCode 4 and it's seems that the user scripts are not supported! How can I continue to use my script ? (I try with automator but I can't use the %%%{PBXSelectionStart}%%% variable for the cursor position and I

问题 I have an iOS 4.3 iPhone app built in Xcode4 that I'm submitting through the Application Loader app. I keep getting this error: Icon specified in the Info.plist not found under the top level app wrapper: iTunesArtwork I do have the following set: iTunesArtwork (JPEG with no extension) in root folder iTunesArtwork reference in Resources file 512x512 image size 'Item 0; under 'Icon Files' array in info.plist Far as I can tell, the above is exactly as it should be for the iTunesArtwork.

问题 This question already has answers here : Can I add my own code snippets to xcode 4? (5 answers) Closed 6 years ago . If you show the Utilities pane on the far right of the XCode window, then select the "{ }" button, it shows code snippets that you can type the shortcut for, or drag and drop into your source code. How do you create your own? 回答1: Although the documentation is very scant on this, I did find a blog post by Jason Brennan that describes step-by-step. Type in the code you want to

问题 My app is crashing in iOS 5 because I have some code that is calling UIKit instances from a secondary thread. You know you have this problem when you see the following error: bool _WebTryThreadLock(bool), 0x811bf20: Multiple locks on web thread not allowed! Please file a bug.
