I am new bie in IOS developement.I am stuck in this problem
I am using Mailcore2 api in my ios app.I want to get the new emails which are recently coming in Inbox.
Here is my Code
In ViewDidLoad method..
-(void)viewDidLoad
{
[super viewDidLoad];
NSUserDefaults *defaules = [NSUserDefaults standardUserDefaults];
NSString *emailid = [defaules objectForKey:#"emailid" ];
NSString *password = [defaules objectForKey:#"password" ];
session = [[MCOIMAPSession alloc] init];
session.hostname = #"imap.gmail.com";
session.port = 993;
session.username = emailid;
session.password = password;
session.connectionType = MCOConnectionTypeTLS;
MCOIMAPIdleOperation *idle=[session idleOperationWithFolder:#"INBOX" lastKnownUID:64];
[idle start:^(NSError *error)
{
NSLog(#"finished checking account.");
if (error) {
NSLog(#"ERROR-%#",error);
}
else
{
NSLog(#"DONE");
[self fetchemail:10 folder:#"INBOX"];
}
}];
double delayInSeconds = 2.0;
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
[idle interruptIdle];
NSLog(#"HELOO");
});
}
by this method all the emails are loaded when the view is load.
I have use MCOIMAPIdleoperation to get latest emails but it is not working.
but latest email is not fetched.
Please Help to get over it..

I'm getting this message regularly in iOS when I try to load HTML in WKWebView. Also it's repeating when I open a WKWebView page.
WKWebViewConfiguration *conf = [[WKWebViewConfiguration alloc] init];
_articleWebView = [[WKWebView alloc] initWithFrame:_mainView.containterViiew.bounds configuration:conf];
_articleWebView.navigationDelegate = self;
_articleWebView.scrollView.scrollEnabled = NO;
[_mainView.containterViiew addSubview:_articleWebView];
[_articleWebView loadHTMLString:_articleDesc.pageContent baseURL:nil];
Also I'm trying to get the content height of the WKWebView in finish method. When the above error occurs, I am getting different height values.
- (void)webView:(WKWebView *)webView didFinishNavigation:(null_unspecified WKNavigation *)navigation {
[webView evaluateJavaScript:#"document.readyState"
completionHandler:^(id complete, NSError * _Nullable error) {
if (complete != nil) {
NSString *javascriptString = #"var body = document.body;var html = document.documentElement;Math.max(html.offsetHeight);";
[webView evaluateJavaScript:javascriptString
completionHandler:^(id _Nullable result, NSError * _Nullable error) {
if (!error) {
NSNumber *height = result;
NSLog(#"height ----------->>>%#", height);
});
}
}];
}
I am using QuickBlox-iOS SDK for chatting. Login/Signup is working perfectly. Also I am able to send message but the delegate method
- (void)chatDidReceiveMessage:(QBChatMessage *)message;
is not getting called. Here's the code I am using to setup chat. Adding the following code in appDelegate :
// connect to Chat
[[QBChat instance] addDelegate:self];
QBUUser *currentUser = [QBUUser user];
currentUser.ID = [Global sharedInstance].currentUser.ID;
currentUser.password = #"password";
[[QBChat instance] connectWithUser:currentUser completion:^(NSError * _Nullable error) {
NSLog(#"connect to chat error %#",error);
}];
And the below code I am using to send message :
QBChatMessage *message = [QBChatMessage message];
message.recipientID=[Global sharedInstance].QBUserID;
message.senderID=[Global sharedInstance].currentUser.ID;
[message setText:messageTextView.text];
message.dateSent = [NSDate date];
NSMutableDictionary *params = [NSMutableDictionary dictionary];
params[#"save_to_history"] = #YES;
[message setCustomParameters:params];
[QBRequest createMessage:message successBlock:^(QBResponse *response, QBChatMessage *createdMessage) {
NSLog(#"success: %#", createdMessage);
} errorBlock:^(QBResponse *response) {
NSLog(#"ERROR: %#", response.error);
}]
I checked on QuickBlox dashboard. It shows all the sent/received messages. But the delegate is not getting called when I send message to another user. I am not using any additional services classes (QMServices) like they are using in their Example Project. Any help would be appreciated. Thanks
I don't understand why you're using the [QBRequest createMessage:successBlock:errorBlock:] method to send messages to another user.
For me what always worked was to create a chatDialog with the user you're trying to message, like so:
QBChatDialog *dialog = [[QBChatDialog alloc] initWithDialogID:nil
type: QBChatDialogTypePrivate];
dialog.occupantIDs = #[#([Global instance].QBUserID),
#([Global instance].currentUser.user.ID)];
Afterwards, you can call Quickblox method to create the dialog on the servers:
if (dialog.ID == nil) {
[QBRequest createDialog:dialog successBlock:^(QBResponse *response, QBChatDialog *createdDialog) {
[self sendMessageToDialog: dialog withText:#"Hello friend!"];
} errorBlock:^(QBResponse *response) {
NSLog(#"dialog creation err: %#", response);
}];
}
Create the message:
- (QBChatMessage *) createMessageWithText: (NSString *)text andDialog: (QBChatDialog*)dialog {
QBChatMessage *message = [QBChatMessage message];
message.text = text;
message.senderID = [Global instance].currentUser.ID;
message.markable = YES;
message.deliveredIDs = #[#([Global instance].currentUser.ID)];
message.readIDs = #[#([Global instance].currentUser.ID)];
message.dialogID = dialog.ID;
message.dateSent = [NSDate date];
message.recipientID = dialog.recipientID;
message.customParameters = [NSMutableDictionary dictionary];
message.customParameters[kQMCustomParameterDialogID] = dialog.ID;
message.customParameters[kQMCustomParameterDialogType] = [NSString stringWithFormat:#"%lu",(unsigned long)dialog.type];
message.customParameters[#"application_id"] = #"<your-application-id>";
message.customParameters[#"save_to_history"] = #"1";
if (dialog.lastMessageDate != nil){
NSNumber *lastMessageDate = #((NSUInteger)[dialog.lastMessageDate timeIntervalSince1970]);
message.customParameters[kQMCustomParameterDialogRoomLastMessageDate] = [lastMessageDate stringValue];
}
if (dialog.updatedAt != nil) {
NSNumber *updatedAt = #((NSUInteger)[dialog.updatedAt timeIntervalSince1970]);
message.customParameters[kQMCustomParameterDialogRoomUpdatedDate] = [updatedAt stringValue];
}
return message;
}
And then send the message to the dialog:
- (void) sendMessageToDialog: (QBChatDialog *)dialog withText: (NSString *)text {
QBChatMessage *message = [[ChatService shared] createMessageWithText:text andDialog:self.dialog];
[dialog sendMessage:message completionBlock:^(NSError * _Nullable error) {
if (error != nil) {
NSLog(#"error creating message %#", error);
} else {
NSLog(#"message sent!");
}
}];
}
I think following this flux you'll be able to receive the callback through the delegate.
EDIT - I forgot to mention the consts I used in the code above are:
NSString const *kQMCustomParameterDialogID = #"dialog_id";
NSString const *kQMCustomParameterDialogRoomName = #"room_name";
NSString const *kQMCustomParameterDialogRoomPhoto = #"room_photo";
NSString const *kQMCustomParameterDialogRoomLastMessageDate = #"room_last_message_date";
NSString const *kQMCustomParameterDialogUpdatedDate = #"dialog_updated_date";
NSString const *kQMCustomParameterDialogType = #"type";
NSString const *kQMCustomParameterDialogRoomUpdatedDate = #"room_updated_date";
Have you added <QBChatDelegate> into your .h file.
I'm working on an app for iPad iOS 8, and I need to make my app wait for an answer from:
[directions calculateETAWithCompletionHandler:^(MKETAResponse *response, NSError *error) {}]
This method is inside 3 loops. I tried dispatch_semaphore_t, but the app can't continue after this line:
dispatch_semaphore_wait(semaphore, DISPATCH_TIME_FOREVER);
and gets stuck. I tried with dispatch_group_t and got the same result.
I guess that I'm doing something wrong, but I don't know what. I tried to search SO for similar problems and but found nothing. Can someone explain how I could accomplish this?
-(void)setTimesMissions {
for (Driver *d in self.dataList) {
for (Period *p in d.periods) {
for (Mission *m in p.missions) {
MKDirections *directions = ....
// HERE i want the for loop stop until this completionHandler finish
[directions calculateETAWithCompletionHandler:^(MKETAResponse *response, NSError *error) {
//and when he finish here continue
}];
}
}
}
}
Call your method in dispatch_async block.
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
[youClassInstance setTimesMissions];
});
And use dispatch_semaphore_wait in your loop
- (void)setTimesMissions {
Mission *home = [[Mission alloc]init];
Mission *next = [[Mission alloc]init];
for (Driver *d in self.dataList) {
home.clientLat = d.centralPointLat;
home.clientLon = d.centralPointLon;
home.clientPaddres = d.centralAddress;
for (Period *p in d.periods) {
home.times = [[NSMutableArray alloc]init];
if ([p.periodIx isEqualToString:self.thisPeriodIX]) {
for (Mission *m in p.missions) {
Mission *source = home;
Mission *destination = m ;
MKPlacemark *placemarkSource = [[MKPlacemark alloc] initWithCoordinate:CLLocationCoordinate2DMake([source.clientLat doubleValue], [source.clientLon doubleValue]) addressDictionary:nil] ;
MKMapItem *mapItemSource = [[MKMapItem alloc] initWithPlacemark:placemarkSource];
MKPlacemark *placemarkDestination = [[MKPlacemark alloc] initWithCoordinate:CLLocationCoordinate2DMake([destination.clientLat doubleValue], [destination.clientLon doubleValue])addressDictionary:nil] ;
MKMapItem *mapItemDestination = [[MKMapItem alloc] initWithPlacemark:placemarkDestination];
MKDirectionsRequest *directionsRequest = [[MKDirectionsRequest alloc] init];
[directionsRequest setSource:mapItemSource];
[directionsRequest setDestination:mapItemDestination];
directionsRequest.transportType = MKDirectionsTransportTypeAutomobile;
[directionsRequest setRequestsAlternateRoutes:NO];
MKDirections *directions = [[MKDirections alloc] initWithRequest:directionsRequest];
dispatch_semaphore_t semaphore = dispatch_semaphore_create(0);
__block double timeTo;
[directions calculateETAWithCompletionHandler:^(MKETAResponse *response, NSError *error) {
if ( response.expectedTravelTime) {
timeTo = response.expectedTravelTime;
double ans = timeTo;
Time *t = [[Time alloc]init];
t.ix = m.serviceIX;
t.time = ans;
[home.times addObject:t];
}
dispatch_semaphore_signal(semaphore);
}];
dispatch_semaphore_wait(semaphore, DISPATCH_TIME_FOREVER);
}
dispatch_async(dispatch_get_main_queue(), ^{
// code that should be executed on main queue
});
if (next.clientPaddres) {
home = next;
}
}
}
}
}
I am totally new in IOS Development, And I am making a app using MailCore2 api.
Company has told me to use MCOIMApIdleOperation to get the emails from Gmail Server.
I have google all the way to find out solution about this but it is not worth it.
Here is detail about the Problem,
First I want to load the emails from the INBOX folder through MCOIMAPIdleOperation.Below is my code for fetching emails.
- (void)viewDidLoad{
[super viewDidLoad];
//Do any additional setup after loading the view from its nib.
//Made connection with Gmail Imap Server
NSUserDefaults *defaules = [NSUserDefaults standardUserDefaults];
NSString *emailid = [defaules objectForKey:#"emailid" ];
NSString *password = [defaules objectForKey:#"password" ];
session = [[MCOIMAPSession alloc] init];
session.hostname = #"imap.gmail.com";
session.port = 993;
session.username = emailid;
session.password = password;
session.connectionType = MCOConnectionTypeTLS;
idle=[session idleOperationWithFolder:#"INBOX" lastKnownUID:0];
[idle start:^(NSError *err){
MCOIMAPMessagesRequestKind requestKind = (MCOIMAPMessagesRequestKind)
(MCOIMAPMessagesRequestKindHeaders | MCOIMAPMessagesRequestKindStructure |MCOIMAPMessagesRequestKindInternalDate | MCOIMAPMessagesRequestKindHeaderSubject |MCOIMAPMessagesRequestKindFlags);
MCOIMAPFolderInfoOperation *inboxFolderInfo = [session folderInfoOperation:Folder];
NSLog(#"statrt1");
[inboxFolderInfo start:^(NSError *error, MCOIMAPFolderInfo *info)
{
NSLog(#"start2");
BOOL totalNumberOfMessagesDidChange =
self.totalNumberOfInboxMessages != [info messageCount];
self.totalNumberOfInboxMessages = [info messageCount];
NSUInteger numberOfMessagesToLoad =MIN(self.totalNumberOfInboxMessages, nMessages);
if (numberOfMessagesToLoad == 0)
{
self.isLoading = NO;
return;
}
// If total number of messages did not change since last fetch,
// assume nothing was deleted since our last fetch and just
// fetch what we don't have
MCORange fetchRange;
if (!totalNumberOfMessagesDidChange && msgbody.count)
{
numberOfMessagesToLoad -= msgbody.count;
fetchRange = MCORangeMake(self.totalNumberOfInboxMessages -msgbody.count -(numberOfMessagesToLoad - 1),(numberOfMessagesToLoad - 1));
}
// Else just fetch the last N messages
else
{
fetchRange =MCORangeMake(self.totalNumberOfInboxMessages -(numberOfMessagesToLoad - 1),(numberOfMessagesToLoad - 1));
}
MCOIMAPFetchMessagesOperation *imapMessagesFetchOp =[session fetchMessagesByNumberOperationWithFolder:Folder requestKind:requestKind numbers:
[MCOIndexSet indexSetWithRange:fetchRange]];
[imapMessagesFetchOp start:^(NSError *error, NSArray *messages, MCOIndexSet *vanishedMessages)
{
NSSortDescriptor *sort =[NSSortDescriptor sortDescriptorWithKey:#"header.date" ascending:NO];
NSMutableArray *combinedMessages = [NSMutableArray arrayWithArray:messages];
[combinedMessages removeAllObjects];
[combinedMessages addObjectsFromArray:messages];
msgbody=[combinedMessages sortedArrayUsingDescriptors:#[sort]];
[uitable reloadData];
}];
}];
}];
}
By Above code mails are fetched successfully.Problem is when new mail is arrive above code is not running again.what to do so that i can get the new mails when they arrive..
Please help me to solve this issue.
How do I prevent duplicate select from an Array in an NSTokenField. I've implemented the delegate completionsForSubstring.
I was able to remove any duplicates with this approach, which admittedly is a little hacky but it works:
// Be sure to set the delegate of your NSTokenfield either in IB or in code.
#pragma mark - NSTokenFieldDelegate
-(NSArray *)tokenField:(NSTokenField *)tokenField shouldAddObjects:(NSArray *)tokens atIndex:(NSUInteger)index{
double delayInSeconds = .1;
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
NSArray *aray = [tokenField objectValue];
NSOrderedSet *set = [NSOrderedSet orderedSetWithArray:aray];
aray = [set array];
[tokenField setObjectValue:aray];
});
return tokens;
}
The best method I would say is to implement the delegate shouldAddObjects. Write the following code in the delegate.
NSString *newVal = [[tokens objectAtIndex:0] description];
NSArray *aray = [tokenField objectValue];
for (NSString * token in aray) {
#try{
if ([token isEqual:newVal]){
return nil;
}
}
#catch (NSException *exception) {
;
}
}
