多個Xcode項目將無法再在真實的iOS設備上成功編譯

Question

我可能不小心編輯了NSAttributedString.h類和/或相關類，現在看來我所有的Xcode項目（包括我創建的項目）都無法在iPhone上編譯（iPhone 4s iOS版本：9.3.2）（我的部署目標是iOS 9.0。）。

Xcode項目將成功構建並部署到模擬iPhone。

這是我嘗試為iPhone編譯應用程序時收到的錯誤的編輯列表：

我正在使用Xcode 8 Beta。

有誰知道會導致此錯誤的原因嗎？

我嘗試過重新啟動並重新連接iPhone，重新啟動Xcode，重新注視Mac並刪除DerivedData文件夾。 我在這里閱讀到 ， Expected method body可能是由代碼中的“雜散字符”引起的，但是我找不到雜散字符。

這是NSAttributedString.h類：

提前致謝

Answer 1

您刪除了@interface NSAttributedString : NSObject <NSCopying, NSMutableCopying, NSSecureCoding> NS_CLASS_AVAILABLE(10_0, 3_2)下面的@interface NSAttributedString : NSObject <NSCopying, NSMutableCopying, NSSecureCoding>

Answer 2

我認為您錯誤地修改了NSAttributedString.m。

您可以重新安裝xcode以重新安裝。
