I copied the iOS 6 sdk folder into the following directory path-
About the iOS 6 sdk. I restored it from a time machine backup
The folder named ‘iPhoneOS6.1.sdk’ has been made to reside beside ‘iPhoneOS7.0.sdk’.
Then I tweaked the settings by selecting my project- HeavyRotation from the Navigation Area. And then in the Editor Area, I selected HeavyRotation under the Project section and then under the Info tab the “iOS Deployment Target” was reset to 6.1. It initially was 7.0. Again , under Build Settings tab I selected 6.1 as Base SDK which was initially set to 7.0.
Then, under Targets section I selected “HeavyRotation”. There came a number of tabs on the right hand side- General, Capabilities, Info, Build Settings, Build Phases, Build Rules.
I replaced 7.0 options with 6.1 in 2 or 3 of them.
I then redownloaded iOS 6 simulator sdk in the Xcode 5 preferences.
After having done all this (which is bunch of trivial tasks), my project was supposed to work in the iOS 6 environment inside of Xcode 5. It turns out it did not. I then selected the Utilities area and reset a field under the “File inspector”. Builds for “Project Deployment Target (6.1)” and View as “iOS 6.1 and earlier”.
When built and ran the project, i got a strange “iOS Simulator” message saying -" The iOS simualtor cannot install the app". Then i Reset Content and Settings from the drop down menu of the iOS Simulator app. And then i restarted the Xcode 5. Before relaunching the app, i had already cleared the User Library caches.I then ran the project. It builds successfully but when the simulator launches, the console logs an error saying the following-
*** Terminating app due to uncaught exception ‘NSUnknownKeyException’, reason: ‘[<UIApplication 0x8321ad0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key view.’.
Have I landed myself into serious trouble. Please Please Please, if anyone was experiencing this problem and has solved it ,please guide me and tell me where i went wrong.
And about reason for sticking iOS 6- I’m still in learning phase right now. I started the book and solved and learned its content while using iOS 6. Right now i’m on ch8. and i dont want any further diversion. I just want to focus on learning for another 4-5 months until my book studying completes. I thought when i wud install Xcode 5 it would retain older SDKs and libraries. I was clearly mistaken. Any of the expert people, please help with this. The Xcode 5 that im using has kind of gotten messed (to some extent). Please help me with this. If anybody can steer me out of this issue. It may be a trivial issue but still… I havent overcome it… .
