问题 I am using the Xcode 4.2. I did not able to see any method to add Entitlements.plist in this version. So how can i do add that file in my project since i need to install my app on iPhone. 回答1: Select the target in your project and scroll down. You'll see the option to add a custom entitlement. For creating a new entitlement, just create a new plist file from new file menu item. Change it's type to iPhone entitlements as shown below. 来源： https://stackoverflow.com/questions/8547471/how-to-add

问题 I have a strange problem. I use ASIHTTPRequest in a iOS 5 project with ARC enabled. Since ASIHTTPRequest does not support ARC I have disabled ARC on all individual ASIHTTPRequest files. However, when I'm trying to compile my project, xcode still believes that those files are ARC-enabled and it complains. Did I do anything wrong or is that a bug in xcode? Don't tell me to convert ASIHTTPRequest to ARC-compatible code with the refactor tool. I have tried to do that and xcode complains on that

问题 I am developing an app for iOS 5, which have to run in landscape mode. My problem is that I cannot get it to flip initially. I have tried the adding "Initial interface orientation" set to "Landscape (right home button)" and adding the following method to my view controller: - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations return (interfaceOrientation == UIInterfaceOrientationLandscapeRight); } I can wrap my

问题 I am using Xcode 4.2 on a relatively large project (a few ten thousand lines of code) and it is horribly slow. Editing is ok, but whenever I try to compile the project (in Xcode, or with xcodebuild on the command line), my machine (quad core i7 MacBook Pro, 4 GB RAM) crawls to a halt. I have noticed that directly after starting xcodebuild, it spawns more than 8 clang processes, without the "real" compile processes starting. No xcodebuild output is so far seen on stout. I've tried reducing the

问题 I've read a few posts on how to install the missing documentation on Xcode 4.2 by going into the documents manager and downloading it directly. Other questions suggest me to look into the rss feed, but I get only the Mac OS Lion Core reference, I want the iOS reference as well. That's very nice, but I can't connect to the internet from the Mac where I work , no need to enter in details, nor can install Mac OS on the PC where I connect, so my question is pretty simple: Where can I obtain the
