iOS 常用小功能——发邮件

//方法1
//用自带的邮件客户端，发完邮件后不会自动回到原应用
NSURL *url = [NSURL URLWithString:@"mailto://10010@qq.com"];
[[UIApplication sharedApplication] openURL:url];

//方法2
//跟发短信的第2种方法差不多，只不过控制器类名叫做：MFMailComposeViewController
邮件发送后的代理方法回调，发完后会自动回到原应用
- (void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
// 关闭邮件界面
[controller dismissViewControllerAnimated:YES completion:nil];

if (result == MFMailComposeResultCancelled) {
NSLog(@"取消发送");
} else if (result == MFMailComposeResultSent) {
NSLog(@"已经发出");
} else {
NSLog(@"发送失败");
}
}
