FYI have the same problem with the iOS 8 simulator, having not seen the issue on iOS 6/7 simulators or iOS 7 hardware. Found this useful link:
I have REAL misunderstanding with MFMailComposeViewController in Swift (iOS8) in Simulator (note that Swift is not part of the problem)
On the 19th I'll have proper iOS 8 hardware to test on so might be able to confirm if it only happens on the simulator!
EDIT: I can confirm that I'm not seeing it on my iPhone 6 Plus device having seen it every single time I launched it in the iPhone 6 Plus simulator.

Issue is with IOS 8 Simulater . When checked with all devices in IOS 7 and 7.1 Simulater ,MFMailComposeViewController works fine .
