Clang thất bại với mã thoát 254 trong khi chuyển đổi dự án phi ARC sang Objective-C ARC bằng cách sử dụng XCode

Question

Tôi đang cố chuyển đổi dự án không phải ARC (https://github.com/allaboutapps/A3GridTableView) sang ARC bằng Trình chuyển đổi ARC XCode. Tôi nhận được lỗi sau

lệnh /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang thất bại với mã thoát 254.

Tôi đã theo dõi trường hợp 1 của hướng dẫn http://maniacdev.com/2012/01/easily-get-non-arc-enabled-open-source-libraries-working-in-arc-enabled-projects/.

Tôi đang sử dụng phiên bản XCode 4.5.2 với trình biên dịch LLVM của Apple 4.1.

Tôi đã cố gắng google lỗi nhưng không thể liên hệ với trường hợp của tôi. Cảm ơn trước.

Toàn bộ sản lượng lỗi là

Answer 1

Tôi đã có một vấn đề tương tự. Trong trường hợp của bạn, việc thêm @synthesize dataSource = _dataSource vào A3GridTableView.m sẽ giúp ích.

[A3GridTableView setDataSource:] có lỗi quản lý bộ nhớ trong đó có liên quan đến sự cố này.
