通過whatsapp發送文本無法正常工作

Question

我是新來的flex移動應用程序開發，我想通過whatsapp分享一個文本。這是一些代碼，但它不工作。

navigateToURL(new URLRequest("whatsapp://send?text=Hello how r u???") 

你能幫我嗎。 在此先感謝。

試試看看這個代碼。應該完美地工作。

-(void)whatsapp{ 
     NSString *massage = [self stringByEncodingString:@"Your massage"]; 
     NSString *urlWhats = [NSString stringWithFormat:@"whatsapp://send?text=%@",massage]; 
     NSURL *whatsappURL = [NSURL URLWithString:urlWhats]; 
     if ([[UIApplication sharedApplication] canOpenURL: whatsappURL]) { 
      [[UIApplication sharedApplication] openURL: whatsappURL]; 
     } else { 
      UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"WhatsApp not installed." message:@"Your device has to have WhatsApp installed." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; 
      [alert show]; 
     } 
} 

-(NSString *)stringByEncodingString:(NSString *)string{ 
     CFStringRef encodedString = CFURLCreateStringByAddingPercentEscapes(NULL, (CFStringRef)string, NULL, 
                    (CFStringRef)@"!*'();:@&=+$,/?%#[]", kCFStringEncodingUTF8); 
     return CFBridgingRelease(encodedString); 
}
