打開Storyboard時出現Xcode崩潰

Question

為了支持從iOS 7到iOS 9的iOS，我安裝了Xcode 6和7.然后我在Xcode 7上為iPhone創建了一個項目。我在Xcode 6上打開它以在iPhone模擬器7上進行測試。

但是當我點擊Storyboard文件時，Xcode 6崩潰了。

我該如何解決？ 或者還有另一種方式來支持iOS版本？

Answer 1

原因是Xcode 6和7之間存在沖突.Apple在Xcode 7的發行說明中對此進行了揭示。

我按照步驟操作，錯誤得到解決。

“從Xcode的下載首選項安裝iOS 9.0 Simulator Runtime會導致Xcode 6中的Interface Builder安裝在同一台機器上以停止運行。要么避免安裝iOS 9.0 Simulator Runtime，要么移動/ Library / Developer / CoreSimulator / Profiles / Runtimes / iOS \\切換到Xcode 6時將9.0.simruntime更改為備份位置，然后將其移回Xcode 7（23230951）“

Answer 2

得到同樣的問題，經過一些調查，似乎在Xcode更新或Mac OS更新后，從系統庫， PepperUICore.framework和SockPuppetGizmo.framework中刪除了2個私有框架。 但您仍然可以在Xcode 6模擬器SDK中找到它們。

確保在/ System / Library / PrivateFramework /中找不到這兩個框架。 然后使用下面的命令行（用你的Xcode 6 app路徑替換）將私有框架從Xcode 6模擬器SDK復制到你的/ System / Library / PrivateFramework / 。

sudo cp -r /Applications/Xcode6.4.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/PepperUICore.framework /System/Library/PrivateFrameworks/

sudo cp -r /Applications/Xcode6.4.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/SockPuppetGizmo.framework /System/Library/PrivateFrameworks/

現在用Xcode 6打開.xib或.storyboard，它應該沒問題。

Answer 3

嘗試更改故事板檢查器中的“打開”屬性，使其與Xcode 6或6.3兼容。

特別是這個下拉/彈出菜單項：

但是像Kaizoku評論一樣，如果其他東西被打破（例如，如果您的應用程序期望僅在iOS 9中存在的符號或功能），請不要感到驚訝。

可能更好的是為您的應用設置最低部署版本 （例如，到iOS 7），並在iOS 7或iOS 8模擬器中試用，您可以使用Xcode 7下載 。
