Capture Upload Image Failed iOS - ios

Question

I m trying to upload image through AFNetworking.
Following is the way I try to save image in an array. Image uploading starts, but right after the 1.1% of upload it stops uploading without any error. No Idea what is happening.
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[picker dismissViewControllerAnimated:YES completion:nil];
UIImage *chosenImage = info[UIImagePickerControllerOriginalImage];
NSData *imageData=UIImagePNGRepresentation(chosenImage);
ImageObject *imageObject=[[ImageObject alloc]init];
imageObject.image=chosenImage;
imageObject.imageData=imageData;
imageObject.imageUploadStatus=FALSE;
imageObject.isUploaded=FALSE;
[imageObject setDescription:#""];
[imageDataArray addObject:imageObject];
}
After this I upload image with Following method.
-(void)uploadPicturesAndVides:(NSMutableArray *)_list descriptions:(NSMutableArray *)_description categoryID:(NSString *)_catID categoryName:(NSString *)_categoryName index:(NSInteger)_index{
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager.requestSerializer setValue:[SettingValues getRSFToken] forHTTPHeaderField:#"_csrf"];
[manager.requestSerializer setValue:#"USER_Agent_Value" forHTTPHeaderField:#"User-Agent"];
NSString *imageUrl;
imageUrl=[NSString stringWithFormat:#"%#/user/upload/photo",BASE_SERVER_ADDRESS];
NSMutableArray *tempArray=[[NSMutableArray alloc] init];
for (ImageObject *object in _list) {
[tempArray addObject:[object description]];
}
NSString *descriptions;
descriptions=[tempArray componentsJoinedByString:#","];
NSDictionary *parameters = #{#"descriptionImage":descriptions,#"subcategoryId":_catID,#"subcategoryName":_categoryName,#"_csrf": [SettingValues getRSFToken]};
AFHTTPRequestOperation *op = [manager POST:imageUrl parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
NSInteger count=_index;
for (ImageObject *object in _list) {
NSString *imageName = [NSString stringWithFormat:#"IMG00%zd.png",count];
[formData appendPartWithFileData:object.imageData name:#"files" fileName:imageName mimeType:#"image/png"];
}
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
[SettingValues setImageUploadStatus:TRUE];
[self uploadingRequestSuccessfulWithObject:responseObject reqestName:#"picture" index:_index];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
}];
[op setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
double percentDone = (double)totalBytesWritten / (double)totalBytesExpectedToWrite;
[self goBackTouploadingControllerWithProgressResult:percentDone index:_index];
}];
cancelManager=op;
[op start];
}
Following is the image and its progress stays here! no success no failure. :(
Problem is that code works when I upload image through Camera Roll, But when I capture image, it did not.
I put a NSLog(#"progress updated(percentDone) : %f", percentDone); in Progress Block and I found the following logs
2015-02-07 13:07:22.854 APP_Name[2069:60b] progress updated(percentDone) : 0.002105
2015-02-07 13:07:22.858 APP_Name[2069:60b] progress updated(percentDone) : 0.004210
2015-02-07 13:07:22.860 APP_Name[2069:60b] progress updated(percentDone) : 0.006315
2015-02-07 13:07:22.861 APP_Name[2069:60b] progress updated(percentDone) : 0.008413
and then every thing stops.
In Failure block I put following log
NSLog(#"Error: %# ***** %#", operation.responseString, error);
Never executed :(
