ios如何利用系統郵件發送反饋 代碼

    主要是使用MFMailComposeViewController  這個類，封裝下就ok.   

  1.  

將ios的appDelegate類  的laungh函數中，將相應的代碼修改為：

[cpp] view
plaincopy

1. // Set RootViewController to window  
2. if ( [[UIDevice currentDevice].systemVersion floatValue] < 6.0)  
3. {  
4.     // warning: addSubView doesn't work on iOS6  
5.      [window setRootViewController:viewController];  
6.     [window addSubview: viewController.view];  
7. }  
8. else  
9. {  
10.     // use this method on ios6  
11.     [window setRootViewController:viewController];  
12. }  

   
主要目的是 當SDK< 6.0的時候，也設定  

    [window  setRootViewController:viewController];

   以免後面調用 window.rootViewController的時候crash.

2.   標頭檔內容如下:

   

@interface EmailIOS : UIViewController <MFMailComposeViewControllerDelegate>{    MFMailComposeViewController* mailPicker;    UIWindow * window;}- (void)SendMail;@end

3. *.mm檔案實現如下：

   

@implementation EmailIOS- (void)SendMail{    if (![MFMailComposeViewController canSendMail])    {        UIAlertView *alert = [[UIAlertView alloc]  initWithTitle:nil  message:[NSString stringWithUTF8String:LanguageManager::sharedLanguageManager()->getLocalizedString("Please configure your Email first").c_str()]  delegate:nil  cancelButtonTitle:@"OK"  otherButtonTitles:nil];        [alert show];        [alert release];        return ;    }    if(mailPicker != nil)    {        [mailPicker release];    }        mailPicker = [[MFMailComposeViewController alloc] init];    mailPicker.mailComposeDelegate = self;    mailPicker.navigationBar.tintColor=[UIColor colorWithRed:(11.0/255.0) green:(81.0/255.0) blue:(112.0/255.0) alpha:1];    //    mailPicker.navigationBar.tintColor=[UIColor colorWithRed:(90.0/255.0) green:(182.0/255.0) blue:(45.0/255.0) alpha:1];    NSString* strSubject = [NSString stringWithFormat:@"XXX APP反饋"];    [mailPicker setSubject:strSubject];    // Set up recipients    NSArray *toRecipients = [NSArray arrayWithObject:@"XXX@fuckU.com"];    [mailPicker setToRecipients:toRecipients];        NSString * device = [[UIDevice currentDevice] model];    NSString * ios = [[UIDevice currentDevice] systemVersion];         NSString *body = [NSString stringWithFormat:@"請留下您的寶貴建議和意見：\n\n\n以下資訊有助於我們確認您的問題，建議保留。\nApp id:\nApp Version: %s\nDevice: %@\nOS Version: %@\n", GAME_VERSION, device, ios];    [mailPicker setMessageBody:body isHTML:NO];        [self presentModalViewController:mailPicker animated:YES];         mailPicker.view.frame = [UIScreen mainScreen].bounds;    window = [[UIWindow alloc] initWithFrame: [[UIScreen mainScreen] bounds]];        if ( [[UIDevice currentDevice].systemVersion floatValue] < 6.0)    {        // warning: addSubView doesn't work on iOS6        [window addSubview: mailPicker.view];    }    else    {        // use this method on ios6        window.rootViewController = self;        [window setRootViewController:self];    }         [window makeKeyAndVisible];     //    cocos2d::CCDirector::sharedDirector()->////[[[CCDirector sharedDirector] view] insertSubview:mailPicker.view atIndex:30];}- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error{   NSString * message;// Notifies users about errors associated with the interfaceswitch (result){case MFMailComposeResultSent:{message = @"Successfully sent!";UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Email"message:message   delegate:self  cancelButtonTitle:@"OK"  otherButtonTitles:nil];[alert show];[alert release];}break;case MFMailComposeResultFailed:{//message = @"Result: failed";UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Email"message:[NSString stringWithFormat:@"Error!
