iphone email allegato

Question

Ho utilizzato il MessageUI framework per inviare la posta con allegato dalla mia applicazione. Ma ho ottenuto il seguente errore,

2009-09-07 19:52:23.483 emailTest[11711:5b17] 
Error loading /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/DataClassMigrators/AccountMigrator.migrator/AccountMigrator: dlopen(/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/DataClassMigrators/AccountMigrator.migrator/AccountMigrator, 265): Library not loaded: /System/Library/PrivateFrameworks/MobileWirelessSync.framework/MobileWirelessSync

[Switching to process 11711 local thread 0xf03] 

il mio codice è,

MFMailComposeViewController *picker = [[MFMailComposeViewController alloc]init]; 
picker.mailComposeDelegate = self; 
[picker setSubject:@"This is iPhone email attachment test"]; 

UIImage *sampleImg = [UIImage imageNamed:@"iPhone.jpg"]; 
NSData *imageData = UIImageJPEGRepresentation(sampleImg, 1); 
[picker addAttachmentData:imageData mimeType:@"image/png" fileName:@"iPhone.jpg"]; 


NSString *emailBody = @"I am sending the image attachment with iPhone email service"; 
[picker setMessageBody:emailBody isHTML:YES]; 

[self presentModalViewController:picker animated:YES]; 
[picker release]; 

ti prego, aiutami.

Non è necessario digitare l'estensione nel nome file. come "iphone.jpg" non funziona. basta scrivere "iphone" nel nome del file perché già si definisce mimeType. E devi anche definire il percorso per la risorsa.

Di seguito è riportato il codice di esempio per allegare il file "rainy.png" con la posta.

MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init]; 
picker.mailComposeDelegate = self; 

[picker 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"]; 

[picker setToRecipients:toRecipients]; 
[picker setCcRecipients:ccRecipients]; 
[picker setBccRecipients:bccRecipients]; 

// Attach an image to the email 
NSString *path = [[NSBundle mainBundle] pathForResource:@"rainy" ofType:@"png"]; 
NSData *myData = [NSData dataWithContentsOfFile:path]; 
[picker addAttachmentData:myData mimeType:@"image/png" fileName:@"rainy"]; 

// Fill out the email body text 
NSString *emailBody = @"It is raining"; 
[picker setMessageBody:emailBody isHTML:NO]; 

[self presentModalViewController:picker animated:YES]; 
[picker release];

Questo errore sembra essere correlato alla posta in esecuzione nel simulatore e non al codice. Anche campione azioni Apple MailComposer segnala l'errore identico nel simulatore:

Add seguente metodo per chiudere la MFMailComposeViewController:

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult: (MFailComposeResult)result error:(NSError*)error 

{ 
// NEVER REACHES THIS PLACE 
[self dismissModalViewControllerAnimated:YES]; 

NSLog (@"mail finished"); 
} 

Answer 4

uso questo per collegare immagine in una mail, testato in ios 4,5, 6

MFMailComposeViewController *mailer = [[MFMailComposeViewController alloc] init]; 
    UIImage *myImage = [UIImage imageNamed:@"image.png"]; 
    NSData *imageData = UIImagePNGRepresentation(myImage); 
    [mailer addAttachmentData:imageData mimeType:@"image/png" fileName:@"image"];
