Question

您好我正在尝试编译以下代码，但收到错误Use of undeclered identifier AFHTTPClient：

NSData* fileNameData = [fileName dataUsingEncoding:NSUTF8StringEncoding];

NSDictionary *sendDictionary =
    [NSDictionary dictionaryWithObject:fileNameData forKey:@"fileName"];

AFHTTPClient *httpClient =
    [[AFHTTPClient alloc] initWithBaseURL:@"http://www.olcayertas.com"];

NSMutableURLRequest *afRequest =
    [httpClient multipartFormRequestWithMethod:@"POST"
        path:@"/photos"
        parameters:sendDictionary
        constructingBodyWithBlock:^(id <AFMultipartFormData>formData) {
            [formData appendPartWithFileData:photoImageData
                name:self.fileName.text
                fileName:filePath
                mimeType:@"image/jpeg"];
        }];

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:afRequest];
[operation setUploadProgressBlock:^(NSInteger bytesWritten, NSInteger totalBytesWritten, NSInteger totalBytesExpectedToWrite) {

    NSLog(@"Sent %d of %d bytes", totalBytesWritten, totalBytesExpectedToWrite);

}];

[operation setCompletionBlock:^{
    //NSLog(@"%@", operation.responseString); //Gives a very scary warning
}];

[operation start];

我正在使用CocoaPods，这是我的pod文件：

platform :ios, '7'
pod 'AFNetworking', '~> 2.0'
pod 'AFNetworking/NSURLSession', '~> 2.0'

Answer 1

您正在使用AFNetworking 2.0，但2.0中不存在AFHTTPClient - 这是1.0功能。检查migration guide，但AFHTTPClient已替换为AFHTTPRequestOperationManager和AFHTTPSessionManager。

另请查看example app for 2.0 - AFAppDotNetAPIClient now子类AFHTTPSessionManager。

Answer 2

在AFNetworking 3.0中，您需要使用AFHTTPSessionManager而不是AFHTTPRequestOperationManager，因为AFHTTPRequestOperationManager已被删除

使用未声明的标识符AFHTTPClient
