Hello, there is a error in my iPhone app. I use the CameraPicker to make and get a picture and then I give it to my methode sendPhoto, which will send the photo to TweetPhoto. Everything works great until I initialize an NSMutableDate with NSData. Here is the code:
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[picker dismissModalViewControllerAnimated:YES];
NSData *imageData = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
[self sendPhoto:(NSString*)@"lola" tweet:(BOOL)TRUE photo:(NSData*)imageData tags:(NSString*)@"" longitude:(float)1024 latitude:(float)512];
}
Here is the sendPhoto-methode:
- (void)sendPhoto:(NSString*)message tweet:(BOOL)tweet photo:(NSData*)photo tags:(NSString*)tags longitude:(float)longitude latitude:(float)latitude {
NSString *url;
if (tweet) {
url = [NSString stringWithFormat:@"http://www.tweetphoto.com/uploadandpostapiwithkey.php"];
} else {
url = [NSString stringWithFormat:@"http://www.tweetphoto.com/uploadapiwithkey.php"];
}
NSString * boundary = @"tweetPhotoBoundaryParm";
NSMutableData *postData = [NSMutableData dataWithCapacity:[photo length] + 1024];
//!!!Here is the error!!!!
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
NSString * userNameString = [NSString stringWithFormat:@"Content-Disposition: form-data; name=\"username\"\r\n\r\n%@", [prefs stringForKey:@"username_preference"]];
NSString * passwordString = [NSString stringWithFormat:@"Content-Disposition: form-data; name=\"password\"\r\n\r\n%@", [prefs stringForKey:@"password_preference"]];
NSString * apiString = [NSString stringWithFormat:@"Content-Disposition: form-data; name=\"api_key\"\r\n\r\n3eceaa7c-6d4d-41ab-be90-2a780e2d1961"];
NSString * messageString = [NSString stringWithFormat:@"Content-Disposition: form-data; name=\"message\"\r\n\r\n%@", message];
NSString * tagsString = [NSString stringWithFormat:@"Content-Disposition: form-data; name=\"tags\"\r\n\r\n%@", tags];
NSString * latString = [NSString stringWithFormat:@"Content-Disposition: form-data; name=\"latitude\"\r\n\r\n%f", latitude];
NSString * longString = [NSString stringWithFormat:@"Content-Disposition: form-data; name=\"longitude\"\r\n\r\n%f", longitude];
NSString * boundaryString = [NSString stringWithFormat:@"\r\n--%@\r\n", boundary];
NSString * boundaryStringFinal = [NSString stringWithFormat:@"\r\n--%@--\r\n", boundary];
[postData appendData:[boundaryString dataUsingEncoding:NSUTF8StringEncoding]];
[postData appendData:[userNameString dataUsingEncoding:NSUTF8StringEncoding]];
[postData appendData:[boundaryString dataUsingEncoding:NSUTF8StringEncoding]];
[postData appendData:[passwordString dataUsingEncoding:NSUTF8StringEncoding]];
[postData appendData:[boundaryString dataUsingEncoding:NSUTF8StringEncoding]];
[postData appendData:[apiString dataUsingEncoding:NSUTF8StringEncoding]];
[postData appendData:[boundaryString dataUsingEncoding:NSUTF8StringEncoding]];
//(...)
}

The console also says this: * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[UIImage length]: unrecognized selector sent to instance 0x3b28df0'
Thanks for your help. Maybe there is just a stupid mistake in the code by me, but please don´t be angry, because I´m just learning programming for 2 1/2 weeks.
