#define URLEMail @"mailto:[email protected]?subject=title&body=content"
NSString *url = [URLEMail stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding ];
[[UIApplication sharedApplication] openURL: [NSURL URLWithString: url]];

Try this out.
试试这个。
-(void)launchMailAppOnDevice
{
NSString *recipients = @"mailto:[email protected]?subject=subjecthere";
NSString *body = @"&body=bodyHere";
NSString *email = [NSString stringWithFormat:@"%@%@", recipients, body];
email = [email stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:email]];
}

stringByAddingPercentEscapesUsingEncoding and openURL are deprecated.
stringByAddingPercentEscapesUsingEncoding 和 openURL 已弃用。
Now use this:
现在使用这个：
#define URLEMail @"mailto:[email protected]?subject=title&body=content"
NSString * encodedString = [URLEMail stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLFragmentAllowedCharacterSet]];
UIApplication *application = [UIApplication sharedApplication];
[application openURL:[NSURL URLWithString: encodedString] options:@{} completionHandler:nil];

Ahoy!
哎呀！
The long and short of it is; you can't.
它的长短是; 你不能。
You can create an email compose view for the purpose of sending emails (see MFMailComposeViewController), but you cannot open applications arbitrarily without a purpose.
您可以创建用于发送电子邮件的电子邮件撰写视图（请参阅MFMailComposeViewController），但您不能无故随意打开应用程序。
See this previous post for clarification: Launch an app from within another (iPhone)
请参阅上一篇文章的说明：从另一个 (iPhone) 中启动应用程序
Really though, it's not much effort for the user to close your app and open Mail so I wouldn't worry too much about it anyway.
不过，实际上，用户关闭您的应用程序并打开邮件并不需要太多努力，因此无论如何我都不会太担心。
