在 iOS 9.0、AFNetworking 2.6.0、XCode 7.0.1 上获取 NSInvalidArgumentException

Question

我的应用程序在我通过 AFNetworking 发起 http 请求后立即崩溃。崩溃是一致的，并且returns出现以下错误信息：

2015-10-02 14:04:40.845 App Name[12130:1274441] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'data parameter is nil'

有什么想法吗？这是负责请求的代码：

AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager manager] initWithBaseURL:[APIClient BASE_URL]];

NSMutableDictionary *parameters = [NSMutableDictionary dictionary];

[parameters setObject:@"password" forKey:@"user[password]"];
[parameters setObject:@"username" forKey:@"user[username]"];

[manager POST:@"/users/sign_in.json" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {

    if (block) {
        // Handle response
    }

}   failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    block(nil, error, operation);
}];

您的问题标题指定："iOS 8.0, AFNetworking 2.6.0, XCode 7.0.1"。我猜这完全是错误的，事实上这是 iOS 9。网络在 iOS 9 中已完全改变； http:// iOS 9 中的请求是非法的，除非您在 Info.plist.

中特别允许它们
