问题 I have been reading the forums and so far none of the solutions suggested works for me. I'm running Xcode 4.4.1 and testing in iPhone 5.1 simulator.

Any thoughts or solutions pls? 回答1: I've met the same problem 1.you can delete the App directy under ~/Library/Application Support/iPhone Simulator/6.0/Applications and ~/Library/Developer/Xcode/DerivedData 2.then you can start Xcode ; in the menubar you can find Project -

问题 What is a Build number and what is its use? Is it the same as version number? 回答1: Additionally, if you add CFBuildDate as a string and CFBuildNumber as a string into your info.plist, the following shell script (when added to your run script build phase /bin/bash will automatically update your build number and date: # Auto Increment Version Script buildPlist=${INFOPLIST_FILE} CFBuildNumber=$(/usr/libexec/PlistBuddy -c "Print CFBuildNumber" $buildPlist) CFBuildNumber=$(($CFBuildNumber + 1))

问题 I've been looking all over the place but I can't find anything. Does anyone know how to create an Xcode 4 plugin? 回答1: As far as I know there is no official way to create Xcode 4 plugins (just like there wasn't one for v3.x). Here is an openradar on Xcode's lack of plugin support: Please support the ability for 3rd parties to extend Xcode via a public plugin API. Aperture, Visual Studio, Eclipse, TextMate and other applications benefit from this ability. I would like to see more advanced

问题 I am running a "old" Xcode 3 project in Xcode 4 and code sense is not working for my own classes. I have tried following: Clean/rebuild Remove Derived Data Installing 4.3 documentation Restart Without any luck. Sometimes the code sense works but mostly I just get "No Completions". 回答1: Try this: Open Organizer then Project Tab. Clear the "Derived Data". Xcode should re-index your project then and code sense should work. At least worked for me. 回答2: I know this is late, but for reference: http

问题 Apple is recommending to compiling for ARM rather than thumb if there are many floating point operations going on. My whole app is almost one big floating point operation. Here's what they say in the iOS App Development Workflow Guide: iOS devices support two instruction sets, ARM and Thumb. Xcode uses Thumb instructions by default because using Thumb typically reduces code size by about 35 percent relative to ARM. Applications that have extensive floating-point code might perform better if

问题 I just upgraded to Xcode 4 and for some reason my app won't run in the simulator or iOS device. It was working perfectly in Xcode 3, but all of a sudden now when I press run the program stops at "Attaching to...". There doesn't seem to be any other info to help with this problem either. For summary you can try following things to tackle the issue: Restart the simulator. Make sure that you haven't included the Info.plist file in your Building Phases -> Copy Bundle Resources. Resources folder

问题 You come at a certain point in the development of every app that what you see in the simulator does not match what you think should happen. Mostly these are human errors -- or at least they are in most of my cases ;-) -- but sometimes Xcode has just 'lost track', or so it seems. I've learnt that the Clean (Shift+Cmd+K) and Clean Build Folder… (Option+Shift+Command+K) menu options can show the difference between your error or Xcode's. My question though is: What does the Clean command do or

问题 How can I display a datetimepicker control on tap of a textbox? I have a user interface that has arrival and departure text fields, and when a user clicks on arrival textbox it should bring up a datetimepicker control up instead of a keyboard and the same with the departure textbox. 回答1: You can use inputView and inputAccessoryView properties of the text field for this. Create the date picker and set it to the input views of the two text fields. Also create another view for the Done button

问题 Xcode4 is asking for a huge number of arguments just to make this simple thing possible: NSString *stringURL = @"twitterriffic://"; NSURL *url = [NSURL URLWithString:stringURL]; [[UIApplication sharedApplication] openURL:url]; What are all these properties for? Why an image? Must I repeat the app identifier here? What role to choose if I want anyone to be able to call this URL to open my app? And what are these Additional url type properties for? I found no Xcode4-related tutorial how to
