Summary: 
The documentation for UIActivityTypeMail specifies that a mailto: url can be passed in as one of the activity items.


Steps to Reproduce:
NSURL *mailURL = [NSURL URLWithString:@"mailto:?Content-type=text/html&subject=Awesome%20Photo&body=Check%20it%20out"];
        
UIActivityViewController *vc = [[UIActivityViewController alloc] initWithActivityItems:@[mailURL] applicationActivities:nil];
    
[self presentViewController:vc animated:YES completion:nil];


Expected Results:
The mail sheet would be presented with the subject "Awesome Photo" and the body would read "Check it out".


Actual Results:
The mail sheet is presented with a body that reads "mailto:?Content type=text/html&subject=Awesome%20Photo&body=Check%20it%20out"


Regression:
Not really a regression since iOS 5 did not have UIActivity however iOS 5 was able to parse mailto: urls  when using

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:mailtoURL]];

I have confirmed that this issue is still present in apps built using the iOS7 SDK both on devices running iOS 6 and those running iOS 7.
