Problem with UITextView, NSUTF8StringEncoding and email

[freshking]

Hi,

I have a uitextview which displays me the some data. Sometimes it fills out my textview (you need to scroll down) and sometimes it doesn't.
Now I want to send this data via email useing NSUTF8StringEncoding.
The problem is when the textview is not filled out the app imports the data properly into Mail but if the text is filled out the email-button doesn't call any action. It just gets clicked down but nothing happen.
This is my code I am using:

- (IBAction)start {

myTimer1 = [NSTimer scheduledTimerWithTimeInterval:0.10 target:self selector:@selector(timerFired: ) userInfo:nil repeats:YES];

recordingText.text = [NSString stringWithFormat: @"Recording Started:\n%s\n", [[[NSDate date]
descriptionWithCalendarFormat:@"%a, %d %b %Y %H:%M:%S" timeZone:nil
locale:[[NSUserDefaults standardUserDefaults] dictionaryRepresentation]]
UTF8String]];

- (void)timerFired: (NSTimer *)timer{

recordingText.text = [NSString stringWithFormat:@"%@\nX: %f Y: %f Z: %f", recordingText.text, x , y , z];
}

- (IBAction)email {

NSString *gtv = recordingText.text;

NSString *urlString = [NSString stringWithFormat:@"mailto:?subject=iPhone&body=%@" , gtv];

NSString *fixedURL = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8St ringEncoding];
NSURL *url = [NSURL URLWithString:fixedURL];

[[UIApplication sharedApplication] openURL:url];
}

Doe anybody see the problem? What am I doing wrong?
Thanks alot!

I have noticed that this problem only occurs when the text gets too long. If its just short mail will be fired without any problems. But when too long you can tap the button to send via email as much as you like and nothing happens.
Maybe this gives somebody the clue to solving my problem here.
Thanks!

I'm having the same problem with a long body in my mailto URL. Did you find a solution to your problem?

[freshking]

Actually I did. This is the code I am using. Note that I use the NSUTF8StringEncoding for the subject and the NSUTF32BigEndianStringEncoding for the body.

- (IBAction)someAction {

NSString *subject = [@"Some subject" stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding];

NSString *body = [myUITextView.text stringByAddingPercentEscapesUsingEncoding: NSUTF32BigEndianStringEncoding];

NSString *urlString = [NSString stringWithFormat:@"mailto:?subject=%@&body=%@",bet reff,body];
NSURL *url = [NSURL URLWithString:urlString];

[[UIApplication sharedApplication] openURL:url];

}

I'm having limited success with this solution. It works for short messages, but I'm still having problems with long messages. It doesn't seem to matter if I use NSUTF32BigEndianStringEncoding or NSUTF8StringEncoding. The body of my message is sometimes 2-3KB. Does anyone know what the URL size limit is for the iPhone mail application? Without support for attachments, this is really a limiting factor for getting data off the iPhone.
