AFNetworking upload image with PUT request? - ios

Question

I'm trying upload image to server using AFNetworking with PUT request.-
UIImage* snap = info[UIImagePickerControllerOriginalImage];
NSData *imageData = UIImageJPEGRepresentation(snap, 0.3);
NSMutableString * fullPath = [NSMutableString stringWithString:API_BASE_URL];
[fullPath appendFormat:#"%#%#",API_VERSION,req];
NSURL * url = [NSURL URLWithString:fullPath];
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:url];
[manager.requestSerializer setValue:[NSString stringWithFormat:#"%#", #kPublicKey] forHTTPHeaderField:#"X-API-KEY"];
[manager.requestSerializer setValue:bodyStr forHTTPHeaderField:#"X-API-DATA"];
NSString *URLString = fullPath;
NSMutableURLRequest *request = [manager.requestSerializer multipartFormRequestWithMethod:#"PUT" URLString:URLString parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:imageData name:#"media" fileName:#"upload.jpg" mimeType:#"image/jpeg"];
} error:nil];
AFHTTPRequestOperation *requestOperation = [manager HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) {
//success
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"failure...");
}];
[requestOperation start];
I'm taking image using iPhone camera and upload it to server but it takes too much time to process and images uploaded on server are in huge size(~10-12MB) although i'm trying to compress the image?
What i'm doing wrong?Any suggestion or sample code would be appreciated.

Answer 1

NSData *imageData = UIImageJPEGRepresentation(snap, 1.0);
The second argument in UIImageJPEGRepresentation denotes the compression quality of the image.As per Apple documentation :
compressionQuality :
The quality of the resulting JPEG image, expressed as a value from 0.0 to 1.0. The value 0.0 represents the maximum compression (or lowest quality) while the value 1.0 represents the least compression (or best quality).
Try reducing this to a number which balances the quality of image and speed of upload.

Answer 2

// manager needs to be init'd with a valid baseURL
NSURL *baseURL = [AfarHTTPSessionManager sharedManager].baseURL;
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:baseURL];
NSData *imageData = UIImageJPEGRepresentation(draftHighlight.largeImage, 1);
// need to pass the full URLString instead of just a path like when using 'PUT' or 'POST' convenience methods
NSString *URLString = [NSString stringWithFormat:#"%#%#", baseURL, _the_rest_of_your_path];
NSMutableURLRequest *request = [manager.requestSerializer multipartFormRequestWithMethod:#"PUT" URLString:URLString parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:imageData name:kCreateHighlightAPIKeyImage fileName:#"highlight_image.jpg" mimeType:#"image/jpeg"];
}];
// 'PUT' and 'POST' convenience methods auto-run, but HTTPRequestOperationWithRequest just
// sets up the request. you're responsible for firing it.
AFHTTPRequestOperation *requestOperation = [manager HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) {
// success
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
// failure
}];
// fire the request
[requestOperation start];
