mailcore2 setConnectionType:MCOConnectionTypeClear，can’t get mail！！！！what is matter？
//initialize the session
self.session = [[MCOIMAPSession alloc] init];

I'm try to do synchronous NSURLSessionDataTask with the below code but unable to proceed.
__block NSData *rData = nil;
__block BOOL taskDone = NO;
__block NSData *rError = nil;
NSURL *url = [NSURL URLWithString:dataURL];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url cachePolicy:1 timeoutInterval:30];
NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration ephemeralSessionConfiguration] delegate:nil delegateQueue:nil];
NSURLSessionDataTask *taskData = [session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
rData = [NSData dataWithData:data];
rError = [error copy];
taskDone = YES;
}];
[taskData resume];
while (taskDone == NO) {
if (_close == YES) {
[taskData cancel];
return nil;
}
usleep(20000);
}
I need to synchronous call so that I can remove the while loop which is not needed.
Below is my code with synchronous call using semaphore
dispatch_semaphore_t sem;
__block NSData *rData = nil;
__block BOOL taskDone = NO;
__block NSData *rError = nil;
NSURL *url = [NSURL URLWithString:dataURL];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url cachePolicy:1 timeoutInterval:30];
// creating semaphore
sem = dispatch_semaphore_create(0);
NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration ephemeralSessionConfiguration] delegate:nil delegateQueue:nil];
NSURLSessionDataTask *taskData = [session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
rData = [NSData dataWithData:data];
rError = [error copy];
taskDone = YES;
//call semaphore
dispatch_semaphore_signal(sem);
}];
[taskData resume];
dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);
dispatch_release(sema);
// THIS part not sure... how can we accommodate this below code
while (taskDone == NO) {
if (_close == YES) {
[taskData cancel];
return nil;
}
usleep(20000);
}
above code could be correct ?
I understand that what you want to do is wait for the DataTask to be completed before continue with you code, the best way is to put your request in a function with a completionHandler.
First create a function that will return a NSURLSessionDataTask with a completion handler:
-(NSURLSessionDataTask*)startSessionDataTaskWithCompletionHandler:(void (^)(NSData *myData))completionBlock {
//Set your request
NSString *dataURL = #"www.yoururl.com";
NSURL *url = [NSURL URLWithString:dataURL];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url cachePolicy:1 timeoutInterval:30];
// I recommend to use sharedSession because is a simple request, so its not needed a specific session configuration.
NSURLSessionDataTask *dataTask = [[NSURLSession sharedSession] dataTaskWithRequest: request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
if (!error) {
if (completionBlock){
completionBlock(data);
return;
//When you call this function, the completionBlock will use this data
}
} else {
//Error handle
return;
}
}];
[dataTask resume];
return dataTask;
}
Then you can call this function from anywhere:
NSURLSessionTask *task = [self startSessionDataTaskWithCompletionHandler:^(NSData *myData) {
// put whatever code you want to perform when the asynchronous data task finish, for example:
rData = [NSData dataWithData:myData];
}];
if (!task) {
// handle failure to create task any way you want
}
You can make NSURLSessionDataTask synchronous with PromiseKit. Install it manually or add the following line to the Podfile if you use CocoaPods (tested with CocoaPods 1.7.3):
pod "PromiseKit", "6.10.0"
Add the following line to the top of the code file:
#import PromiseKit;
Then create a wrapper for your task:
- (AnyPromise*)promiseToLoadData:(NSString*)dataURL {
return [AnyPromise promiseWithResolverBlock:^(PMKResolver _Nonnull resolver) {
NSURL *url = [NSURL URLWithString:dataURL];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url cachePolicy:1 timeoutInterval:30];
NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration ephemeralSessionConfiguration] delegate:nil delegateQueue:nil];
NSURLSessionDataTask *taskData = [session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
if (error != nil) {
resolver([error copy]);
} else {
resolver([NSData dataWithData:data]);
}
}];
[taskData resume];
}];
}
Use wait to resolve the promise synchronously:
id value = [self promiseToLoadData:#"http://your.url"].wait;
if ([value isKindOfClass:[NSData class]]) {
NSLog(#"%#", [[NSString alloc] initWithData:value encoding:NSUTF8StringEncoding]);
}
I was trying to load data for the table using values from server.I am using NSURLSession datatask with completion handler. Whenever it reaches the nsurlsession, it shows error.This is the code which i used for getting data.
- (void)geturl:(NSString *)urlvalue datavalues:(NSString *)string fetchGreetingcompletion:(void (^)(NSDictionary *dictionary, NSError *error))completion{
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"%#%#?%#",common.getUrlPort,urlvalue,common.getappversion]];
NSLog(#"url=%#",url);
NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration: defaultConfigObject delegate: nil delegateQueue: [NSOperationQueue mainQueue]];
NSMutableURLRequest * urlRequest = [NSMutableURLRequest requestWithURL:url];
[urlRequest addValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[urlRequest addValue:common.getauthtoken forHTTPHeaderField:#"Authorization"];
//Create POST Params and add it to HTTPBody
[urlRequest setHTTPMethod:#"GET"];
NSURLSessionDataTask * dataTask =[defaultSession dataTaskWithRequest:urlRequest
completionHandler:^(NSData *data, NSURLResponse *response, NSError *connectionError) {
NSLog(#"Response:%# %#\n", response, connectionError);
if (data.length > 0 && connectionError == nil)
{
NSDictionary *greeting = [NSJSONSerialization JSONObjectWithData:data options:0 error:NULL];
NSString *code = [NSString stringWithFormat:#"%#",[greeting valueForKey:#"code"]];
if([code isEqualToString:#"-1"]){
[self loaderrorview:greeting];
}
else{
if (completion)
completion(greeting, connectionError);
}
}
else if(data == nil){
NSDictionary *errorDict=[[NSDictionary alloc]initWithObjectsAndKeys:#"Server Connection Failed",#"error", nil];
if (completion)
completion(errorDict,connectionError);
}
else
{
NSDictionary *greeting = [NSJSONSerialization JSONObjectWithData:data options:0 error:NULL];
if (completion)
completion(greeting, connectionError);
}
}];
[dataTask resume];
}
The code which i used for getting data from server:
-(void)getdataexplore{
if (!common.checkIfInternetIsAvailable) {
[self.view makeToast:Nointernetconnection];
} else {
NSLog(#"There is internet connection");
[SVProgressHUD setDefaultMaskType:SVProgressHUDMaskTypeBlack];
[SVProgressHUD showWithStatus:#"Loading..."];
[apiservice geturl:loadexploredata datavalues:nil fetchGreetingcompletion:^(NSDictionary *dictionary, NSError *error) {
//NSLog(#"Test %# Error %#",dictionary,error);
if(error == nil){
authDictionary = dictionary;
[self loaddata];
}
else{
[SVProgressHUD dismiss];
[view_business makeToast:#"Request timed out" duration:2.0 position:CSToastPositionCenter];
}
}];
}
}
The code which i used for storing server data to array:
-(void)loaddata
{
[SVProgressHUD setDefaultMaskType:SVProgressHUDMaskTypeBlack];
[SVProgressHUD showWithStatus:#"Loading..."];
//[SVProgressHUD dismiss];
NSString *msg = [authDictionary valueForKey:#"msg"];
NSString *code = [NSString stringWithFormat:#"%#",[authDictionary valueForKey:#"code"]];
if([code isEqualToString:#"201"]){
NSDictionary *explore = [authDictionary valueForKey:#"explore_obj"];
arr_CBcategories = [explore valueForKey:#"cb_categories"];
[common setarrCBCaterory:arr_CBcategories];
arr_CBcategoryid = [arr_CBcategories valueForKey:#"id"];
[common setarrCateroryID:arr_CBcategoryid];
arr_CBcategorytitle = [arr_CBcategories valueForKey:#"title"];
[common setarrCaterorytitle:arr_CBcategorytitle];
arr_CBcategoryslug = [arr_CBcategories valueForKey:#"slug"];
[common setarrCateroryslug:arr_CBcategoryslug];
arr_CBcategoryimage = [arr_CBcategories valueForKey:#"image"];
[common setarrCateroryimage:arr_CBcategoryimage];
arr_CBcategorycode = [arr_CBcategories valueForKey:#"code"];
}
I am getting error like "Unable to run main thread". Any solution for this.
I am using NSMutableURLRequest is working correct when I am using
- (void)postAsynchronousOnQueue:(NSOperationQueue*)queue completionHandler:(void (^)(NSURLResponse*, NSData*, NSError*))completionHandler {
NSURLRequest* request = [self createPostRequest];
[NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:completionHandler];
}
-(NSURLRequest*)createPostRequest {
NSMutableURLRequest* request = [[HttpRequest requestWithRelativePath:#"/photo"] toNSMutableURLRequest];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:[self encodeParamsForUpload]];
return request;
}
But the issue is when my app is in background mode it won't work.
Here is my HttpRequest class method:
+(id)requestWithRelativePath:(NSString*)docpath {
return [[HttpRequest alloc] initWithRelativePath:docpath server:server username:email password:password];
}
-(id)initWithRelativePath:(NSString*)docpath server:(NSString*)server username:(NSString*)username password:(NSString*)password {
if (self = [super init]) {
docpath = [docpath stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding];
_request = [self createRequestWithDocPath:docpath server:server username:username password:password];
}
return self;
}
- (NSMutableURLRequest*)createRequestWithDocPath:(NSString*)docpath server:(NSString*)server username:(NSString*)username password:(NSString*)password {
NSURL* url = [NSURL URLWithString:[NSString stringWithFormat:#"https://%#%#", server, docpath]];
NSMutableURLRequest* request = [[NSMutableURLRequest alloc] initWithURL:url];
[request setTimeoutInterval:120.0];
if ((username != nil) && (password != nil)){
NSString *authStr = [NSString stringWithFormat:#"%#:%#", username, password];
NSData *authData = [authStr dataUsingEncoding:NSUTF8StringEncoding];
NSString *authValue = [NSString stringWithFormat:#"Basic %#", [self base64Encoding:authData]];
[request setValue:authValue forHTTPHeaderField:#"Authorization"];
}
return request;
}
From, stack overflow I found NSURLSession to work API calls in background. So I used NSURLSession. Here is my updated code which I did:
- (void)postAsynchronousOnQueue:(NSOperationQueue*)queue completionHandler:(void (^)(NSURLResponse*, NSData*, NSError*))completionHandler {
NSURLRequest* request = [self createPostRequest];
[NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:completionHandler];
}
-(NSURLRequest*)createPostRequest {
NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration ephemeralSessionConfiguration];
NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration: defaultConfigObject delegate: nil delegateQueue: [NSOperationQueue mainQueue]];
NSMutableURLRequest* request = [[HttpRequest requestWithRelativePath:#"/photo"] toNSMutableURLRequest];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:[self encodeParamsForUpload]];
//Create task
NSURLSessionDataTask *dataTask = [defaultSession dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
//Handle your response here
[[NSURLSession sharedSession]invalidateAndCancel];
}];
[dataTask resume];
return request;
}
But, when I am using NSURLSession the request is sending two times I already put the breakpoints in NSMutableURLRequestline but it call only once.
Please, help me to solve the issue.
Your createPostRequest is creating a request and submitting it via NSURLSession. But it also returns the NSURLRequest and postAsynchronousOnQueue proceeds to submit it again, this time through the deprecated NSURLConnection.
Remove the NSURLConnection code and just rely upon NSURLSession to issue the request.
For example:
- (void)postAsynchronousOnQueue:(NSOperationQueue*)queue completionHandler:(void (^)(NSData *, NSURLResponse*, NSError*))completionHandler {
NSURLSession *defaultSession = [NSURLSession sharedSession];
NSMutableURLRequest* request = [[HttpRequest requestWithRelativePath:#"/photo"] toNSMutableURLRequest];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:[self encodeParamsForUpload]];
NSURLSessionDataTask *dataTask = [defaultSession dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
//Handle your response here
[queue addOperationWithBlock:^{
completionHandler(data, response, error);
}];
}];
[dataTask resume];
}
I'm working with AFNetworking (2.4.1) in a mac application. I'm hoping to add my own block operation that is for after completion of all of the other operations (which are AFHTTPRequestOperation). I have tried adding dependencies between the completionOperation and the others, but the completionOperation block still executes before the others have completed with success or failure.
A cut down version of the code that illustrates the basics is below. Is anyone able to suggest how to make this work? Thanks.

While implementing this code, Here I am getting few errors,

twittername is undeclared. can any tell what is right parameter here?
