AFNetworking 2.0 HTTP POST Progress - ios

Question

How can I get the progress of an AFHTTPRequest? I've tried searching all over the net.
I am using:
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *params = #{#"gameId" : datas[0], #"p1": datas[1], #"p2":datas[2], #"turn":datas[3] };
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
[manager POST:#"http://localhost/thepath/isprivate/thefile.php"
parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
}];
Is there like, a property or method I can use to access the progress of an AFNetworking 2.0 HTTP POST?

Answer 1

Try this:
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *params = #{#"gameId" : datas[0], #"p1": datas[1], #"p2":datas[2], #"turn":datas[3] };
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] requestWithMethod:#"POST" URLString:#"http://localhost/thepath/isprivate/thefile.php" parameters:params error:&error];
AFHTTPRequestOperation *requestOperation = [manager HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"operation success: %#\n %#", operation, responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
[requestOperation setUploadProgressBlock:^(NSUInteger bytesWritten, NSInteger totalBytesWritten, NSInteger totalBytesExpectedToWrite) {
double percentDone = (double)totalBytesWritten / (double)totalBytesExpectedToWrite;
NSLog(#"progress updated(percentDone) : %f", percentDone);
}];
[requestOperation start];
Hope this helps.

The shortest way way to implement this is
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
AFHTTPRequestOperation *requestOperation = [manager POST:#"/service/user/authenticate" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
//Your Business Operation.
NSLog(#"operation success: %#\n %#", operation, responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
//Here is the upload progress
[requestOperation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
double percentDone = (double)totalBytesWritten / (double)totalBytesExpectedToWrite;
//Upload Progress bar here
NSLog(#"progress updated(percentDone) : %f", percentDone);
}];

You can use following method
- (NSURLSessionUploadTask *)uploadTaskWithRequest:(NSURLRequest *)request
fromData:(NSData *)bodyData
progress:(NSProgress * __autoreleasing *)progress
completionHandler:(void (^)(NSURLResponse *response, id responseObject, NSError *error))completionHandler
of AFHTTPSessionManager class.
UPDATE:
Usually you will prefer to use KVO to get uploading values. So something like following should be used:
static void * kDGProgressChanged = &kDGProgressChanged;
...
[progress addObserver:self
forKeyPath:#"fractionCompleted"
options:NSKeyValueObservingOptionNew
context:kDGProgressChanged];
...
- (void)observeValueForKeyPath:(NSString *)keyPath
ofObject:(id)object
change:(__unused NSDictionary *)change
context:(void *)context
{
if (kDGProgressChanged == context) {
dispatch_async(dispatch_get_main_queue(), ^{
[self updateProgressInfo];
});
}
}
