在尝试使用 Objective-C 为项目设置 .clang 格式文件时，我遇到了一个问题，即使最大线宽为 0，长的 Objective-C 方法也会被切割成多行。例如，这个：

AFHTTPRequestOperation *returnOperation = [self POST:endpoint parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        [formData appendPartWithFormData:[[secureStore valueForKey:storeKey] dataUsingEncoding:NSUTF8StringEncoding] name:tokenKey];
        if ([provider isEqualToString:kTwitterKey]) {
            [formData appendPartWithFormData:[[secureStore twitterSecretToken] dataUsingEncoding:NSUTF8StringEncoding] name:kTwitterSecretKey];
            [formData appendPartWithFormData:[email dataUsingEncoding:NSUTF8StringEncoding] name:kEmailKey];
        }
        [formData appendPartWithFormData:[[secureStore token] dataUsingEncoding:NSUTF8StringEncoding] name:tokenKey];
    } success:^(AFHTTPRequestOperation *operation, NSDictionary *response) {
        [secureStore setToken:response[kTokenKey]];
        if (completionHandler) {
            completionHandler(nil, response);
        }
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        if (completionHandler) {
            completionHandler(error, nil);
        }
    }];

变成了这样：

AFHTTPRequestOperation *returnOperation = [self POST:endpoint
        parameters:nil
        constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
          [formData appendPartWithFormData:[[secureStore valueForKey:storeKey] dataUsingEncoding:NSUTF8StringEncoding] name:tokenKey];
          if ([provider isEqualToString:kTwitterKey]) {
              [formData appendPartWithFormData:[[secureStore twitterSecretToken] dataUsingEncoding:NSUTF8StringEncoding] name:kTwitterSecretKey];
              [formData appendPartWithFormData:[email dataUsingEncoding:NSUTF8StringEncoding] name:kEmailKey];
          }
          [formData appendPartWithFormData:[[secureStore token] dataUsingEncoding:NSUTF8StringEncoding] name:kTokenKey];
        }
        success:^(AFHTTPRequestOperation *operation, NSDictionary *response) {
          [secureStore setToken:response[kTokenKey]];
          if (completionHandler) {
              completionHandler(nil, response);
          }
        }
        failure:^(AFHTTPRequestOperation *operation, NSError *error) {
          if (completionHandler) {
              completionHandler(error, nil);
          }
        }];

例如，我想将方法​​拆分为多行留给开发人员，但仍然让格式化程序检查正确的大括号放置。关于如何修复奇怪的内部缩进的建议也将不胜感激。

编辑：如果有人感兴趣，这是我的 .clang 格式文件。我主要是在尝试复制《纽约时报》的 Objective-C 风格。

我正在使用以下配置，它不会破坏长方法

BasedOnStyle: LLVM
IndentWidth: 4
AllowShortIfStatementsOnASingleLine: true
IndentCaseLabels: false
ColumnLimit: 0

您可以使用以下命令获取 LLVM 设置

clang-format -style=llvm -dump-config > .clang-format
