【问题描述】：

我正在尝试通过 WhatsApp 共享文本 + url，但没有在 WhatsApp 文本字段中填充任何内容。

我尝试了以下代码：

NSString *urlString = [NSString stringWithFormat:@"http://www.mouthshut.com/contest?ref=%@&inv_via=whatsapp&act=reg", UserName];

//NSURL *url = [NSURL URLWithString:urlString];
//urlString = [urlString stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

NSString * urlWhats = [NSString stringWithFormat:@"whatsapp://send?text=Writing a review is better than whatsapp. Win cash prizes daily on MouthShut.com \n Join Now %@", urlString];

NSURL * whatsappURL = [NSURL URLWithString:[urlWhats stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

if ([[UIApplication sharedApplication] canOpenURL: whatsappURL]) {
  [[UIApplication sharedApplication] openURL: whatsappURL];
} else {
  UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Alert!" message:@"Your device has no WhatsApp installed." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
  [alert show];
}

我可以知道为什么这个问题被否决了吗？
