i'm using this code to upload a file to the server , the stream is not detected on the server , the problem is that i use the same code but in a different project and it works perfectly ! I've included the appropriate headers ! what is going on ? i've spent the last couple of hours working on this problem please help
-(void)upload

NSString *st = [[NSBundle mainBundle] pathForResource:#"R" ofType:#"caf"];
NSData *d = [NSData dataWithContentsOfFile:st];

NSString *action = #"SendStreamMessage";
NSMutableDictionary *parameters = [NSMutableDictionary dictionary];
[parameters setObject:#"209" forKey:#"param1"];

Trying to write a method for my iPhone program that given a URL address to a file, it would download to the iOS App's Documents Directory.
Following AFNetowrking's Documentation, it seems to work fine except that the filename is always some garbage.
I'm using Xcode 5 with AFNetworking 2.0 added to my project. Here's the code that I have so far:
//#import "AFURLSessionManager.h"
//On load (or wherever):
[self downloadFile:#"http://www.irs.gov/pub/irs-pdf/fw4.pdf"];
-(void)downloadFile:(NSString *)UrlAddress
{ NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
NSURL *URL = [NSURL URLWithString:UrlAddress];
NSURLRequest *request = [NSURLRequest requestWithURL:URL];
NSURLSessionDownloadTask *downloadTask = [manager downloadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response)
{
NSURL *documentsDirectoryPath = [NSURL fileURLWithPath:[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject]];
return [documentsDirectoryPath URLByAppendingPathComponent:[targetPath lastPathComponent]];
}
completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error)
{
NSLog(#"File downloaded to: %#", filePath);
}];
[downloadTask resume];
}
The end result is that the file is successfully downloaded to my documents directory, but with a garbled name:
File downloaded to: file:///Users/myname/Library/Application%20Support/iPhone%20Simulator/7.0/Applications/25188DCA-4277-488E-B08A-4BEC83E59194/Documents/CFNetworkDownload_60NWIf.tmp
The end result I'm expecting:
File downloaded to: file:///Users/myname/Library/Application%20Support/iPhone%20Simulator/7.0/Applications/25188DCA-4277-488E-B08A-4BEC83E59194/Documents/fw4.pdf
I used cocoapods to add AFNetworking to my project:
pod 'AFNetworking', "~> 2.0"
Lastly, what do I need to do to get the progress of the download?
This is the answer I was able to create:
-(void)downloadFile:(NSString *)UrlAddress
{
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:UrlAddress]];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
NSString *pdfName = #"The_PDF_Name_I_Want.pdf";
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *path = [[paths objectAtIndex:0] stringByAppendingPathComponent:pdfName];
operation.outputStream = [NSOutputStream outputStreamToFileAtPath:path append:NO];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Successfully downloaded file to %#", path);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
[operation setDownloadProgressBlock:^(NSUInteger bytesRead, long long totalBytesRead, long long totalBytesExpectedToRead) {
NSLog(#"Download = %f", (float)totalBytesRead / totalBytesExpectedToRead);
}];
[operation start];
}
I am open to improvements or suggestions :)
Simply you can replace this line:
return [documentsDirectoryPath URLByAppendingPathComponent:[targetPath lastPathComponent]];
with:
return [documentsDirectoryPath URLByAppendingPathComponent:#"fw4.pdf"];
since [targetPath lastPathComponent] returns something like CFNetworkDownload_60NWIf.tmp
I have followed several tutorials that use the NSFetchedResultsController class to retrieve and display data to show in a UITableView. What if I simply want to display pieces of my JSON result set in a text box on a simple UIViewController? Does anyone have an example how to do this? Below is a snippet of my code;
// Request Object with json paramaters
RequestInquiry *requestInquiry = [[RequestInquiry alloc] init];
requestInquiry.docType = #"T";
//requestInquiry.documentNum = #"999999999";
requestInquiry.documentNum = self.strTicketNum;
requestInquiry.clientAccount = #"6";
requestInquiry.clientCode = #"02";
requestInquiry.token = #"f1234XFASF43434";
requestInquiry.requestType = #"submit";
requestInquiry.userId = #"XXXX";
requestInquiry.class1 = #"class com.rest.client.JsonRequest";
[[RKObjectManager sharedManager] postObject:requestInquiry path:#"/RestIVR/restservices/ticketservices/jinquiry" parameters:nil success:nil failure:^(RKObjectRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#",error);
}];
- (void)callRemoteServiceWithPath: (NSString *)path postObject: (id)object andParameters: (NSString *)params withBlock:(void (^)(id ))block {
RKObjectManager *manager = [[MFRestKit sharedDataManager] objectManager];
NSData *postData = [params dataUsingEncoding:NSUTF8StringEncoding];
NSURL *url = [NSURL URLWithString:baseUrl];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:path relativeToURL:url]];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
[AFNetworkActivityIndicatorManager sharedManager].enabled = YES;
RKManagedObjectRequestOperation *operation = [manager managedObjectRequestOperationWithRequest:request managedObjectContext:manager.managedObjectStore.persistentStoreManagedObjectContext success:^(RKObjectRequestOperation *operation1, RKMappingResult *mappingResult) {
block ([mappingResult array]);
} failure:^(RKObjectRequestOperation *operation1, NSError *error) {
RKLogDebug(#"Failure %#",error.debugDescription);
block (error);
}];
[manager enqueueObjectRequestOperation:operation];
}
I want to wait until server reponse and parse XML done, then call another function. How can i do that? I used this code to send request to server and use NSXMLParser to parse XML response.
NSURL *url1 = [NSURL URLWithString:#"linkserver"];
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL: url1] ;
NSDictionary *params1 = #{
#"a" : vd;
#"b" : #"all"
};
NSMutableURLRequest *afRequest = [httpClient requestWithMethod:#"GET" path:nil parameters:params1] ;
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:afRequest];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Success");
NSString * parsexmlinput = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
[self parseXMLFile:parsexmlinput];// parse xml
[self getItemFromStatus];// wait to call another function at here???
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"error: %#", error);
}
];
[httpClient enqueueHTTPRequestOperation:operation];
}
Please give me any suggestion. Thanks much
You have to make your request synchronous.
refer code something like:
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"https://api.twitter.com/1.1/friends/ids.json?"]
cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData
timeoutInterval:10];
[request setHTTPMethod: #"GET"];
NSError *requestError;
NSURLResponse *urlResponse = nil;
NSData *response1 = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&requestError];
check this tutorial Ray Wenderlich using AFnetworking.
Using blocks and callbacks
- (IBAction)xmlTapped:(id)sender{
NSString *weatherUrl = [NSString stringWithFormat:#"%#weather.php?format=xml",BaseURLString];
NSURL *url = [NSURL URLWithString:weatherUrl];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
AFXMLRequestOperation *operation =
[AFXMLRequestOperation XMLParserRequestOperationWithRequest:request
success:^(NSURLRequest *request, NSHTTPURLResponse *response, NSXMLParser *XMLParser) {
XMLParser.delegate = self;
[XMLParser setShouldProcessNamespaces:YES];
[XMLParser parse];
}
failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, NSXMLParser *XMLParser) {
UIAlertView *av = [[UIAlertView alloc] initWithTitle:#"Error Retrieving Weather"
message:[NSString stringWithFormat:#"%#",error]
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[av show];
}];
[operation start];
}
You can do it in synchronous way...
NSURLResponse *response = nil;
NSError *error = nil;
NSURL *url = [NSURL URLWithString:urlStr];
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
httpClient.parameterEncoding = AFFormURLParameterEncoding;
NSMutableURLRequest *request = [httpClient requestWithMethod:#"POST" path:[url path] parameters:params];
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString * parsexmlinput = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
if(error) {
errorCallback(error, nil);
} else {
//parse the xml here
}
OR
You can achive it by adding [operation waitUntilFinished],after it's added to the operation queue.Refer this==>Can AFNetworking return data synchronously (inside a block)?
OR
EDIT: In case you don't want to use the AFNetworking library.I prefer this way.
NSString *action_Post =[[NSString alloc] initWithFormat:#"authToken=%#",theMutableString];
NSURL *action_Url =[NSURL URLWithString:#"ur url here"];
NSData *action_PostData = [action_Post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *action_postLength = [NSString stringWithFormat:#"%d", [action_PostData length]];//your parameter to be posted here
NSMutableURLRequest *action_Request = [[NSMutableURLRequest alloc] init];
[action_Request setURL:action_Url];
[action_Request setHTTPMethod:#"POST"];
[action_Request setValue:action_postLength forHTTPHeaderField:#"Content-Length"];
[action_Request setValue:#"application/xml" forHTTPHeaderField:#"Accept"];
//[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[action_Request setHTTPBody:action_PostData];
NSURLResponse *action_response;
NSData *action_Result = [NSURLConnection sendSynchronousRequest:action_Request returningResponse:&action_response error:&error];
if (!action_Result)
{
NSLog(#"Error");
}
else
{
//Parse your xml here
//call ur function
}
Modify it according to your GET/PUT methods.But i suggest you to go for POST method,as it is refered to be as secured one.
I want to post an array value in JSON.
Below is my code :
-(void)getConnection {
NSArray *comment=[NSArray arrayWithObjects:#"aaa",#"bbb",#"ccc",#"hello,yes,tell", nil];
NSURL *aurl=[NSURL URLWithString:#"http://sajalaya.com/taskblazer/staffend/form/iphonearraytest.php"];
NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:aurl cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPMethod:#"POST"];
NSData *jsonData2 = [NSJSONSerialization dataWithJSONObject:comment options:NSJSONWritingPrettyPrinted error:nil];
NSString *new = [[NSString alloc] initWithData:jsonData2 encoding:NSUTF8StringEncoding];
// NSString *new = [comment JSONString];
// NSArray *new=[comment jsonvalue];
NSString *postString=[NSString stringWithFormat:#"tag=&comment=%#&total=%#",new,#"4"];
NSLog(#"this is post string%#",postString);
[request setHTTPBody:[postString dataUsingEncoding:NSUTF8StringEncoding]];
[NSURLConnection connectionWithRequest:request delegate:self];
}
We don't know your question, but my answer is short and simple. You should use great open source library for this, which is: AFNetworking, and do request like this:
_httpClient = [[AFHTTPClient alloc] initWithBaseURL:[[NSURL alloc] initWithString:#"http://sajalaya.com"]];
[_httpClient registerHTTPOperationClass:[AFJSONRequestOperation class]];
NSData *jsonData2 = [NSJSONSerialization dataWithJSONObject:comment options:NSJSONWritingPrettyPrinted error:nil];
NSString *new = [[NSString alloc] initWithData:jsonData2 encoding:NSUTF8StringEncoding];
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
new, #"comment",
#4, #"total,
nil];
NSMutableURLRequest *request = [self.httpClient requestWithMethod:#"POST"
path:#"/taskblazer/staffend/form/iphonearraytest.php"
parameters:params];
request.timeoutInterval = 8;
AFJSONRequestOperation *operation = [[AFJSONRequestOperation alloc] initWithRequest:request];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
// success
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
// failure
}];
Please use the following Mutable Array Operation componentsJoinedByString.
e.g.
NSMutableArray *commennts=[NSMutableArray arrayWithObjects:#"aaa",#"bbb",#"ccc",#"hello,yes,tell", nil];
NSString* strCommentsJoin = [commennts componentsJoinedByString:#","]; // Please use your separator
I am using MGtwitterengine in iPhone , I want to use USER search API http://api.twitter.com/1/users/search.json?q={username} but I don't find any method for this in MGTwitterengine. how can I use this API in iphone to get users.
Thanks
Use like This :-

if ([spaceString rangeOfCharacterFromSet:set].location == NSNotFound)
{
NSString *Name = [self.searchName stringByReplacingOccurrencesOfString:#" " withString:#"%20"];
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"https://api.twitter.com/1/users/search.json?q=%#",Name]];
