I want to present a MFMailComposeViewController from a modal view controller. Basically this method works, but it does not work reliably:
-(void)sendMailTapped:(id)sender{
[self resetButtonsStateAfterTapping:sender];
[self dismissPopover];
if (filesize>10) {
[self showAlertForExceededMaximumAttachmentSize];
return;
}
#try {
MFMailComposeViewController *picker =
[[MFMailComposeViewController alloc] init];
if ([MFMailComposeViewController canSendMail]) {
picker.mailComposeDelegate = self;
NSURL *path =[NSURL urlWithPath:[pageInfoDict valueForKey:#"file_name"]
docId:[pageInfoDict valueForKey:#"id_doc"]
encrypted:[[pageInfoDict valueForKey:#"encrypted"]
boolValue]] ;
NSString *fileName = [pageInfoDict valueForKey:#"title"];
if([fileName length] == 0) {
fileName = [path lastPathComponent];
}
if(![fileName hasSuffix:[path pathExtension]]){
fileName=[fileName stringByAppendingFormat:#".%#",[path pathExtension]];
}
[picker setSubject:[#"Send document: " stringByAppendingString:fileName]];
NSArray *ccRecipients = [NSArray arrayWithObjects:
[[CustomisationConfig getAppConfig] getCCMail],nil];
[picker setCcRecipients:ccRecipients];
NSArray *bccRecipients = [NSArray arrayWithObjects:
[[CustomisationConfig getAppConfig] getBCCMail],nil];
[picker setBccRecipients:bccRecipients];
NSData *myData = [path decryptedData];
[picker addAttachmentData:myData
mimeType:fileMIMEType(fileName) fileName:fileName];
NSString *emailBody = [NSString stringWithFormat:
#"\n\nThis file was sent using %#.",
[DCConfiguration getHumanReadableAppName] ];
[picker setMessageBody:emailBody isHTML:NO];
[self presentViewController:picker animated:true completion:^(void){}];
}
}
#catch (NSException *exception) {
NSLog(#"ContextMenuViewController sendMailTapped:%#",exception.description);
}
}
If I restart my iPad and open the app, the picker will be presented only on the second tap on the corresponding button.
If I click again on the button after this, the picker will be presented on first touch everytime and it works perfectly, until I shutdown and restart the iPad.
The following is printed to the console:
Warning: Attempt to present <MFMailComposeViewController: 0x200cbb70> on <ContextMenuViewController: 0x200cd1a0> whose view is not in the window hierarchy!
What is calling the sendMailTapped: method? If its interface builder, you need to change it to IBAction instead of void, and connect them in interface builder.

I am sending SQLite(Coredata sqlite file) file via email but found empty data in all tables in the received mail.
I am using below code:
MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];
mc.mailComposeDelegate = self;
[mc setSubject:subject];
[mc setMessageBody:body isHTML:FALSE];
if (attachmentData) {
[mc addAttachmentData:attachmentData mimeType:fileMimeType fileName:fileName];
}
if (!recipients || recipients.count == 0) {
recipients = #[];
}
[mc setToRecipients:recipients];
[presentedViewController presentViewController:mc animated:YES completion:nil];
Here, fileMimeType = "application/x-sqlite3" and fileName: xyz.sqlite
Found the same question here, but with no solution. Any idea how to do that?
As I indicated in comments, iOS uses SQLite’s WAL mode by default, so you need to include the WAL file as an attachment.
Are you sure that you attachmentData isn't nil?
How large is your attachmentData?
How are you constructing your data from the sqlite file?
This test code seemed to work fine for me with sending a simple sample database:
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
[self sendSampleMailWithDbAttached];
}
- (void)sendSampleMailWithDbAttached {
MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];
mc.mailComposeDelegate = self;
[mc setSubject:#"Message Subject"];
[mc setMessageBody:#"Message Body" isHTML:NO];
NSString *sqliteFilePath = [self createTestDb];
NSData *attachmentData = [NSData dataWithContentsOfFile:sqliteFilePath];
if (attachmentData) {
[mc addAttachmentData:attachmentData mimeType:#"application/x-sqlite3" fileName:#"xyz.sqlite"];
}
[mc setToRecipients:#[#"fake#email.com"]];
[self presentViewController:mc animated:YES completion:nil];
}
- (NSString *)createTestDb {
NSString *databasePath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]
stringByAppendingPathComponent: #"xyz.sqlite"];
sqlite3 *db;
if (sqlite3_open([databasePath UTF8String], &db) == SQLITE_OK) {
NSString *query = #"CREATE TABLE IF NOT EXISTS test(abc TEXT, def TEXT);";
if (sqlite3_exec(db, [query UTF8String], NULL, NULL, NULL) == SQLITE_OK) {
query = #"INSERT INTO test(abc, def) VALUES('ABC', '123');";
}
sqlite3_close(db);
}
return databasePath;
}
I'm having a problem where every time I click the button that calls on my MFMessageComposeViewController nothing happens. More specifically it freezes before it displays the controller and I am not able to do anything.
Here's my code:
- (IBAction)getQuote:(id)sender {
NSString * inputProduct =_productTextField.text;
NSString * inputYear = _yearTextField.text;
NSString * inputMake = _makeTextField.text;
NSString * inputEmail = email.text;
NSString * inputDescript = _descript.text;
emailConfirmation.text = email.text;
//email subject
NSString *emailTitle = #"Love Shack Electronics";
//email content
if ([conditionlabel isEqual: #"Fair"]) {
NSString *emailBody = [NSString stringWithFormat:#"Product:%# Make:%# Year Manufactured:%# Description:%# Condition:Fair Email:%#",inputProduct,inputMake,inputYear,inputDescript, inputEmail];
NSArray *recipient = [NSArray arrayWithObject:#"LoveShackElectronics#gmail.com"];
MFMailComposeViewController *SuperLovedEmail = [[MFMailComposeViewController alloc]init];
[SuperLovedEmail setTitle:emailTitle];
[SuperLovedEmail setToRecipients:recipient];
[SuperLovedEmail setMessageBody:emailBody isHTML:NO];
[SuperLovedEmail setUserActivity:false];
[self presentViewController:SuperLovedEmail animated:YES completion:nil];
[SuperLovedEmail setEditing:false];
If anyone can help or figure out what is wrong with my code it would be greatly appreciated.
Please check in device and latest Xcode version. it's work fine. it not work then put into dispatch method like below
dispatch_async(dispatch_get_main_queue(),
^{
if ([conditionlabel isEqual: #"Fair"])
{
NSString *emailBody = [NSString stringWithFormat:#"Product:%# Make:%# Year Manufactured:%# Description:%# Condition:Fair Email:%#",inputProduct,inputMake,inputYear,inputDescript, inputEmail];
NSArray *recipient = [NSArray arrayWithObject:#"LoveShackElectronics#gmail.com"];
MFMailComposeViewController *SuperLovedEmail = [[MFMailComposeViewController alloc]init];
[SuperLovedEmail setTitle:emailTitle];
[SuperLovedEmail setToRecipients:recipient];
[SuperLovedEmail setMessageBody:emailBody isHTML:NO];
[SuperLovedEmail setUserActivity:false];
[self presentViewController:SuperLovedEmail animated:YES completion:nil];
[SuperLovedEmail setEditing:false];
}
});
I am using a custom tableview cell that displays text in chat bubbles and its working fine.
But i want to display images in chat.
For that i am doing belowed steps:
TO choose and upload file:
- (IBAction)btnAttachments:(id)sender{
self.imagePicker = [[UIImagePickerController alloc] init];
self.imagePicker.allowsEditing = NO;
self.imagePicker.delegate = self;
self.imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:self.imagePicker animated:YES completion:nil];}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
UIImage *imgChosen = info[UIImagePickerControllerOriginalImage];
imgChat = imgChosen;
[picker dismissViewControllerAnimated:YES completion:NULL];
// Upload new avatar to Content module
NSData *avatar = [[NSData alloc] initWithData:UIImagePNGRepresentation(imgChat)];
//
//[QBContent TUploadFile:avatar fileName:#"MyAvatar" contentType:#"image/png" isPublic:NO delegate:self];
[QBContent TUploadFile:avatar fileName:#"userChat" contentType:#"image/png" isPublic:YES delegate:self];}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker{
[picker dismissViewControllerAnimated:YES completion:NULL];
}
in Completed with result:
if(result.success && [result isKindOfClass:[QBCFileUploadTaskResult class]])
{
QBCFileUploadTaskResult *res = (QBCFileUploadTaskResult *)result;
NSUInteger uploadedFileID = res.uploadedBlob.ID;
QBChatMessage *message = [[QBChatMessage alloc] init];
message.recipientID = self.opponent.ID;
NSMutableDictionary *msgDict = [[NSMutableDictionary alloc]init];
[msgDict setValue:[NSNumber numberWithInt:uploadedFileID] forKey:#"fileID"];
message.customParameters = msgDict;
[[QBChat instance] sendMessage:message];
}
To download file:
- (void)chatDidReceiveMessageNotification:(NSNotification *)notification{
QBChatMessage *message = notification.userInfo[kMessage];
if(message.customParameters != nil)
{
NSUInteger fileID = [message.customParameters[#"fileID"] integerValue];
// download file by ID
[QBContent TDownloadFileWithBlobID:fileID delegate:self];
}
in completed with result:
if(result.success && [result isKindOfClass:[QBCFileDownloadTaskResult class]])
{
QBCFileDownloadTaskResult *res = (QBCFileDownloadTaskResult *)result;
if ([res file])
{
UIImageView* imageView = [[UIImageView alloc] initWithImage:
[UIImage imageWithData:[res file]]];
[self.messages addObject:imageView];
[self.tblObj reloadData];
}
}
Now, How to display that downloaded image in my chat?
Instruct me about the custom cell which will be used for displaying images.
I am using tab bar in my iOS app. When I tap on the scan tab, i invoked the delegate method to start the camera immediately on scan tab. When I start the camera to scan the QR Code and tap on cancel button before scanning, I get the blank view. How to display the view when camera is dismissed
- (void) openCameraScanner
{
ZBarReaderViewController *reader = [[ZBarReaderViewController alloc] init];
reader.readerDelegate = self;
reader.supportedOrientationsMask = ZBarOrientationMaskAll;
reader.showsZBarControls = YES;
ZBarImageScanner *scanner = reader.scanner;
[scanner setSymbology: ZBAR_I25
config: ZBAR_CFG_ENABLE
to: 0];
[self presentViewController:reader animated:YES completion:nil];
reader.showsZBarControls = YES;
//reader.cameraOverlayView = [self commonOverlay];
}
- (void) imagePickerController: (UIImagePickerController*) reader
didFinishPickingMediaWithInfo: (NSDictionary*) info
{
// ADD: get the decode results
id<NSFastEnumeration> results =
[info objectForKey: ZBarReaderControllerResults];
ZBarSymbol *symbol = nil;
for(symbol in results)
// EXAMPLE: just grab the first barcode
break;
// EXAMPLE: do something useful with the barcode data
//resultsView.text = symbol.data;
NSString *urlString = symbol.data;
NSURL *url = [NSURL URLWithString:urlString];
NSLog(#"Query after scan = %#", [url query]);
//Extract id from URL which is there in QR Code --- start
NSMutableDictionary *dictionary = [[NSMutableDictionary alloc] init];
for(NSString *param in [urlString componentsSeparatedByString:#"&"])
{
NSArray *elements = [param componentsSeparatedByString:#"="];
if([elements count]<2)
continue;
[dictionary setObject:[elements objectAtIndex:1] forKey:[elements objectAtIndex:0]];
NSLog(#"value is == %#", [elements objectAtIndex:1]);
//Extract id from URL which is there in QR Code --- end
if([[elements objectAtIndex:1] intValue])
{
NSUserDefaults *defaultsForAsk = [NSUserDefaults standardUserDefaults];
idToAsk = [NSString stringWithFormat:#"%d",[[elements objectAtIndex:1] intValue]];
[defaultsForAsk setObject:idToAsk forKey:#"IDTOASKVIEW"];
flagToShowView = YES;
listViewCntrl.getFlag = flagToShowView;
[self viewDidLoadForDynamicFields];
}
else if([elements objectAtIndex:1] == [NSNull null])
{
[reader dismissViewControllerAnimated:YES completion:Nil];
UIAlertView *message = [[UIAlertView alloc] initWithTitle:#"Invalid QR Code scanned" message:#"Please scan Collaborator's QR Code" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[message show];
}
}
image.image =
[info objectForKey: UIImagePickerControllerOriginalImage];
// ADD: dismiss the controller (NB dismiss from the *reader*!)
//[reader dismissViewControllerAnimated:YES completion:nil];
[reader dismissViewControllerAnimated:YES completion:Nil];
}
You can re display the view using -(void)viewWillAppear:(BOOL)animated method of your ViewController class.
I need one button called email button to do one selection from multiple item from picker view to attach that selected item via email. I am stuck at the IBAction. Here is my progress.
M File :
-(void)pickerViewEmail:(UIPickerView *)pickerViewEmail didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
if ([[musicList objectAtIndex:row] isEqual:#"m1"])
{
MFMailComposeViewController *pickerEmail = [[MFMailComposeViewController alloc] init];
pickerEmail.mailComposeDelegate = self;
NSString *path = [[NSBundle mainBundle] pathForResource:#"m1" ofType:#"mp3"];
NSData *myData = [NSData dataWithContentsOfFile:path];
[pickerEmail addAttachmentData:myData mimeType:#"audio/mp3" fileName:#"m1"];
[pickerEmail setSubject:#"Hello!"];
// Set up recipients
NSArray *toRecipients = [NSArray arrayWithObject:#"first#example.com"];
NSArray *ccRecipients = [NSArray arrayWithObjects:#"second#example.com", #"third#example.com", nil];
NSArray *bccRecipients = [NSArray arrayWithObject:#"fourth#example.com"];
[pickerEmail setToRecipients:toRecipients];
[pickerEmail setCcRecipients:ccRecipients];
[pickerEmail setBccRecipients:bccRecipients];
// Fill out the email body text
NSString *emailBody = #"Hello";
[pickerEmail setMessageBody:emailBody isHTML:NO];
[self presentModalViewController:pickerEmail animated:YES];
[pickerEmail release];
}
if ([[musicList objectAtIndex:row] isEqual:#"m2"])
{
}
if ([[musicList objectAtIndex:row] isEqual:#"m3"])
{
}
IBAction :
-(IBAction)showEmail
{
if ([MFMailComposeViewController canSendMail])
{
[self pickerEmail]; I have a yellow error when i call this. What is the right solution?
}
else
{
}
}
iOS : How to attach a multiple attachment file in one button using pickerview method?
I don't understand your call [self pickerEmail]
Higher in your code, pickerEmail seems to be an object, of type MFMailComposeViewController, not a method. So the call [self pickerEmail] does not have any sense in Objective-C
