UIActivityViewController ne montrant pas le corps du texte dans gmail

j'utilise uiactivityviewcontroller pour afficher l'option de partage. Tout fonctionne sauf lorsque L'utilisateur sélectionne L'option Gmail sharing. Si l'utilisateur choisit e-mail, puis il affiche le contenu correctement. Mais si je choisis gmail alors rien n'est affiché dans le corps du texte.

voici le code: 

 NSString *str = [NSString stringWithFormat:@"%@",@"Check the application"];
 NSArray* dataToShare = @[str];  // ...or whatever pieces of data you want to share.

UIActivityViewController* activityViewController = [[UIActivityViewController alloc] initWithActivityItems:dataToShare applicationActivities:nil];
[activityViewController setValue:@"Check it out" forKey:@"subject"];

if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0")) {
    activityViewController.popoverPresentationController.sourceView = self.view;
    activityViewController.popoverPresentationController.sourceRect = CGRectMake(0,self.view.frame.size.height, self.view.frame.size.width, 400);

}

[self presentViewController:activityViewController animated:YES completion:nil];

[activityViewController setCompletionHandler:^(NSString *activityType, BOOL completed) {
    if(completed){

    }
}];
}

- (NSString *)activityViewController:(UIActivityViewController *)activityViewController subjectForActivityType:(NSString *)activityType{
    return @"Check it out";
}

vous pouvez utiliser le schéma D'URL Gmail pour créer une sous-classe D'UIActivity:

le code ci-dessous a été extrait cette réponse: https://stackoverflow.com/a/12766330/3726577 

//ActivityViewCustomActivity.h
@interface ActivityViewCustomActivity : UIActivity

@end

//ActivityViewCustomActivity.m
@implementation ActivityViewCustomActivity

- (NSString *)activityType {
    return @"googlegmail";
}

- (NSString *)activityTitle {
    return @"Gmail";
}

- (UIImage *)activityImage {
    // Note: These images need to have a transparent background and I recommend these sizes:
    // iPadShare@2x should be 126 px, iPadShare should be 53 px, iPhoneShare@2x should be 100
    // px, and iPhoneShare should be 50 px. I found these sizes to work for what I was making.

    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
    {
        return [UIImage imageNamed:@"iPadShare.png"];
    }
    else
    {
        return [UIImage imageNamed:@"iPhoneShare.png"];
    }
}

- (BOOL)canPerformWithActivityItems:(NSArray *)activityItems {
    NSLog(@"%s", __FUNCTION__);
    return YES;
}

- (void)prepareWithActivityItems:(NSArray *)activityItems {
    NSLog(@"%s",__FUNCTION__);
}

- (UIViewController *)activityViewController {
    NSLog(@"%s",__FUNCTION__);
    return nil;
}

- (void)performActivity {
    NSString *email = @"googlegmail:///co?subject=Check it out&body=Check the application";
    email = [email stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

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

    [self activityDidFinish:YES];
}

@implementation ViewController2

- (void)viewDidLoad{
    [super viewDidLoad];

    NSString *textItem = @"Check the application";

    ActivityViewCustomActivity * ca = [ActivityViewCustomActivity new];

    UIActivityViewController *activityVC =
    [[UIActivityViewController alloc] initWithActivityItems:@[textItem] applicationActivities:[NSArray arrayWithObject:ca]];

    activityVC.excludedActivityTypes = @[UIActivityTypePostToWeibo, UIActivityTypeAssignToContact, UIActivityTypePrint, UIActivityTypeCopyToPasteboard, UIActivityTypeSaveToCameraRoll];
    [activityVC setValue:@"Check it out" forKey:@"subject"];

    activityVC.completionHandler = ^(NSString *activityType, BOOL completed)
    {
        NSLog(@" activityType: %@", activityType);
        NSLog(@" completed: %i", completed);
    };

    [self presentViewController:activityVC animated:YES completion:nil];
}

ressemble à un bug dans Gmail Share extension. S'il vous plaît vérifier si votre URL a &, passing & caractère rend le sujet et le corps du message vide. Vous pouvez utiliser & à la place.

PS: je n'ai pas vérifié les autres caractères spéciaux.

C'est un peu délicat dans Swift 3 et iOS 9+.

D'abord, vous devez ajouter googlegmail à LSApplicationQueriesSchemes dans Info.plist

Deuxièmement, voici à quoi ressemble ma sous-classe UIActivity :
