Answer 1

#define URLEMail @"mailto:sb@sw.com?subject=title&body=content"

 NSString *url = [URLEMail stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding ]; 
 [[UIApplication sharedApplication]  openURL: [NSURL URLWithString: url]];

Answer 2

试试吧.

-(void)launchMailAppOnDevice
{
    NSString *recipients = @"mailto:myemail@gmail.com?subject=subjecthere";
    NSString *body = @"&body=bodyHere";

    NSString *email = [NSString stringWithFormat:@"%@%@", recipients, body];
    email = [email stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:email]];
}

Answer 3

stringByAddingPercentEscapesUsingEncoding 和 openURL 已弃用。

现在使用这个：

#define URLEMail @"mailto:sb@sw.com?subject=title&body=content"

NSString * encodedString = [URLEMail stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLFragmentAllowedCharacterSet]];

UIApplication *application = [UIApplication sharedApplication];
    [application openURL:[NSURL URLWithString: encodedString] options:@{} completionHandler:nil];
