无法在iOS 9中与Whatsapp共享文本

Question

在iOS 8及更低版本上与Whatsapp共享文本时，此代码运行正常，但在iOS 9上共享时无效。

- (IBAction)btnWhatsApp:(id)sender {
    NSString *msg = shareText;
    NSString *urlWhats = [NSString stringWithFormat:@"whatsapp://send?text=%@",msg];
    NSURL *whatsappURL = [NSURL URLWithString:[urlWhats stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

    if ([[UIApplication sharedApplication] canOpenURL: whatsappURL]) {
        [[UIApplication sharedApplication] openURL: whatsappURL];
    }
    else {
        UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"WhatsApp not installed." message:@"Your device has no WhatsApp installed." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
        [alert show];
    }

    [self.tabBarController.tabBar setHidden:NO];
    [viewShare setHidden:YES];
}
