I want to update to the latest version of AFNetworking. I was wondering how to download a PDF from a server to display it in my app.
On the old version I used this code:
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
operation.responseSerializer = [AFHTTPResponseSerializer serializer];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
[webView loadData:responseObject MIMEType:#"application/pdf" textEncodingName:nil baseURL:nil];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
//error handling
}
[operation start];
What does the code look like in AFNetworking 2.0 to get the same job done? Do I have to use another class of AFNetworking?
Just need to add
operation.responseSerializer = [AFHTTPResponseSerializer serializer];
Now it is working so far. Thanks.

I need to download image with progress bar. This is what I've got for in AFNetworking 1.x which is not working for AFNetworking 3.x.
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:self.mediaItem.media_item_hd_url]];
AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
op.responseSerializer = [AFImageResponseSerializer serializer];
[op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
UIImage *image = responseObject;
_image = image;
[self.delegate browserItem:self loaded:1.0 finished:YES];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) { }];
[op setDownloadProgressBlock:^(NSUInteger bytesRead, long long totalBytesRead, long long totalBytesExpectedToRead) {
CGFloat progress = ((CGFloat)totalBytesRead)/((CGFloat)totalBytesExpectedToRead);
[self.delegate browserItem:self loaded:progress finished:NO];
}];
[[NSOperationQueue mainQueue] addOperation:op];
Finally this is what I could come up with, which is not complete. I have no idea how to use progress in code block.
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:self.mediaItem.media_item_hd_url]];
NSURLSessionDownloadTask *downloadTask = [manager downloadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) {
NSURL *documentsDirectoryURL = [[NSFileManager defaultManager] URLForDirectory:NSDocumentDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:NO error:nil];
return [documentsDirectoryURL URLByAppendingPathComponent:[response suggestedFilename]];
} completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) {
NSLog(#"File downloaded to: %#", filePath);
// UIImage *image = response;
// _image = image;
[self.delegate browserItem:self loaded:1.0 finished:YES];
}];
[downloadTask resume];
You can get best framework RSNetworkKit which handles all the network call with an ease. It has internally implemented AFNetworking 3.0. It'll gives you download progress in single method either you upload, download.
It has also an enhanced method to show progress on UIImageView.
You can find it here. https://github.com/rushisangani/RSNetworkKit
I want to upload files to my server from my app. The code below is working great when app is active. If I press home button or open another app uploading stops.
I activated background fetch but still not working.
Afnetworking has background support but I cant figure out how I implement this feature to my code.
NSString *str=[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:#"Archive.zip"];
NSDictionary *parameters = #{#"foo": #"bar"};
NSURL *filePath = [NSURL fileURLWithPath:str];
AFHTTPRequestSerializer *serializer = [AFHTTPRequestSerializer serializer];
NSData *imageData=[NSData dataWithContentsOfURL:filePath];
NSMutableURLRequest *request =
[serializer multipartFormRequestWithMethod:#"POST" URLString:#"http://url"
parameters:parameters
constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:imageData
name:#"image"
fileName:#"Archive.zip"
mimeType:#"application/zip"];
}];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
AFHTTPRequestOperation *operation =
[manager HTTPRequestOperationWithRequest:request
success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Success %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Failure %#", error.description);
}];
[operation setUploadProgressBlock:^(NSUInteger __unused bytesWritten,
long long totalBytesWritten,
long long totalBytesExpectedToWrite) {
NSLog(#"Wrote %lld/%lld", totalBytesWritten, totalBytesExpectedToWrite);
}];
[operation start];
Change this line
[operation start];
to this
[operation setShouldExecuteAsBackgroundTaskWithExpirationHandler:^{
// Handle iOS shutting you down (possibly make a note of where you
// stopped so you can resume later)
}];
[manager.operationQueue addOperation:operation];

I need to send all my forms on server, firstly text forms and then images. Do someone working with it?
The documentation page of AFNetworking shows the following example:
Multi-Part Request
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *parameters = #{#"foo": #"bar"};
NSURL *filePath = [NSURL fileURLWithPath:#"file://path/to/image.png"];
[manager POST:#"http://example.com/resources.json" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileURL:filePath name:#"image" error:nil];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Success: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
I'm trying to have my app load an HTML web page into a "responseObject" that I can later parse.
Here is my code:
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:#"application/xhtml+xml"];
NSDictionary *parameters = #{#"ghinno": #"1151213"};
[manager GET:#"http://m.ghin.com/HLR.aspx" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"HTTP: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
...and this is the output. I should be seeing the html from the webpage. Can you help me understand what I am doing wrong?
Ah, the answer lies below...
Essentially, it was an encoding / decoding of the response object that was causing my issues. Here is the final solution: (notice the line beginning with "NSString)...
NSURL *URL = [NSURL URLWithString:#"http://m.ghin.com/HLR.aspx?ghinno=1151213"];
NSURLRequest *request = [NSURLRequest requestWithURL:URL];
AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSString *string = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSLog(#"%#", string);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
[op start];
I am using cocoapods to install AFNetworking and AFOAuth2Client. The issue is that it can't import a header file, AFJSONREquestOperation. I have no idea where this dependency lies. Is it another pod or extension to AFNetworking?
It depends of you installed AFNetworking 2.x version, but AFOAuth2 used 1.x version (the latest 1.x is 1.3.3)
If you used Cocoapods, just write in pod file
pod 'AFNetworking', '1.3.3' and than run "pod install"
#LIAL's answer is correct -- as of right now, AFOAuth2Client is not compatible with AFNetworking 2.0. There is an open pull request https://github.com/AFNetworking/AFOAuth2Client/pull/55 that is supposed to make AFOAuth2Client work with AFNetworking 2.0.
You could fork the repo of mlwelles or use https://github.com/mlwelles/AFOAuth2Client.git by modifying your Podfile for AFOAuth2Client line to look like this:
pod 'AFOAuth2Client', :git => 'git://github.com/mlwelles/AFOAuth2Client.git'
Try importing it like this:
#import <AFNetworking/AFJSONRequestOperation.h>
If you can't that way, please make sure you are using Xcode 5. Happened to me when using Xcode 4.6.3.
AFHTTPRequestOperationManager Based Code
AFNetworking 2.x
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:#"http://example.com/resources.json" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
AFNetworking 3.x
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager GET:#"http://example.com/resources.json" parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
AFHTTPRequestOperation Based Code
AFNetworking 2.x
NSURL *URL = [NSURL URLWithString:#"http://example.com/resources/123.json"];
NSURLRequest *request = [NSURLRequest requestWithURL:URL];
AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
op.responseSerializer = [AFJSONResponseSerializer serializer];
[op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
[[NSOperationQueue mainQueue] addOperation:op];
AFNetworking 3.x
NSURL *URL = [NSURL URLWithString:#"http://example.com/resources/123.json"];
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager GET:URL.absoluteString parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
This answer it's helpful for both user who have use AFNetworking 2.x & 3.x
Thanks.
