Xcode biên dịch lỗi từ .pch? (iOS)

Question

Trong khi thực hiện thay đổi đối với ứng dụng iPhone tôi đã lưu và biên dịch; có các lỗi dưới đây ... undid tất cả mọi thứ và tôi bây giờ bị mắc kẹt với những lỗi này. Tôi đã thử làm sạch việc xây dựng, sao chép các tập tin ra khỏi thư mục này, đã thử xây dựng trên một máy khác. Không có gì tôi có thể nghĩ về giải quyết nó, sự thay đổi tôi đã thực hiện là tập tin .xib; Tôi đã xóa IBOutlet vì tôi không còn cần phần tử.

Có ai biết làm thế nào tôi có thể giải quyết những vấn đề này -> xin lỗi vì đầu ra gỡ lỗi dài nhưng nghĩ quá nhiều thông tin sẽ tốt hơn quá ít.

Answer 1

Tôi vừa gặp phải sự cố tương tự với iOS 4 SDK. Sau khi tôi thay đổi trình biên dịch từ trình biên dịch LLVM 1.5 thành LLVM GCC 4.2 hoặc GCC 4.2, mọi thứ đều được trả về OK.

Đây có phải là lỗi Clang không?

Answer 2

Nó có vẻ là một lỗi trong 4.1, vì vậy nếu bạn chưa cập nhật (chưa) để 4.2, thêm video này vào tập tin tiền tố của bạn:

#if TARGET_IPHONE_SIMULATOR 
#define __IPHONE_OS_VERSION_MIN_REQUIRED 040100 
#warning "Remove This in SDK 4.2, needed because of a bug in SDK 4.1" 
#endif
