Как отправить изображение или текст в whatsapp из моего приложения ios?

Question

Я использую этот код для обмена изображениями с Whatsapp из моего приложения iOS, но контроллер всегда входит в состояние else. Пожалуйста, дайте мне решение.

if ([[UIApplication sharedApplication] canOpenURL: [NSURL URLWithString:@"whatsapp://app"]]) 
{ 
    UIImage *iconImage = [UIImage imageNamed:dict23[@"profileimg"]]; 
    NSString *savePath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/whatsAppTmp.wai"]; 
    [UIImageJPEGRepresentation(iconImage, 1.0) writeToFile:savePath atomically:YES];  
    documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:savePath]]; 
    documentInteractionController.UTI = @"net.whatsapp.image";    
    documentInteractionController.delegate = self; 

    [documentInteractionController presentOpenInMenuFromRect:CGRectMake(0, 0, 0, 0) inView:self.view animated: YES]; 
} 
else 
{   
    UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"WhatsApp not installed." message:@"Your device has no WhatsApp installed." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; 
    [alert show]; 
}

Используйте этот код для обмена только текст на Whats приложение.

NSString * msg = @"Hi! I am using app! download it at https://itunes.apple.com/us/app/google-search/id284815942?mt=8"; 

    msg = [msg stringByReplacingOccurrencesOfString:@" " withString:@"%20"]; 
    msg = [msg stringByReplacingOccurrencesOfString:@":" withString:@"%3A"]; 
    msg = [msg stringByReplacingOccurrencesOfString:@"/" withString:@"%2F"]; 
    msg = [msg stringByReplacingOccurrencesOfString:@"?" withString:@"%3F"]; 
    msg = [msg stringByReplacingOccurrencesOfString:@"," withString:@"%2C"]; 
    msg = [msg stringByReplacingOccurrencesOfString:@"=" withString:@"%3D"]; 
    msg = [msg stringByReplacingOccurrencesOfString:@"&" withString:@"%26"]; 

    NSString * urlWhats = [NSString stringWithFormat:@"whatsapp://send?text=%@",msg]; 
       NSURL * whatsappURL = [NSURL URLWithString:urlWhats]; 
    if ([[UIApplication sharedApplication] canOpenURL: whatsappURL]) 
    { 
      [[UIApplication sharedApplication] openURL: whatsappURL]; 
    } 
    else 
    { 
      UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"WhatsApp" message:@"Your device has no WhatsApp installed." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; 
        [alert show]; 
    }

Вы можете поделиться текстом с WhatsApp, как указано ниже:

NSString *msgStr = [NSString stringWithFormat:@"whatsapp://send?text=%@ ,msgString]; 
     NSURL * whatsappURL = [NSURL URLWithString:[msgStr 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]; 
     }

NSString * urlWhats = [NSString stringWithFormat:@"whatsapp://send?text=%@",@"YOUR STRING"]; 
    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 WhatsApp installed." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
