跟随误差显示白名单您的应用希望在Info.plist中查询LSApplicationQueriesSchemes键（字符串数组）下的任何URL方案：

随着方案包括在Info.plist的一切和以前一样。当你连接到iOS 9时，你不仅限于50个不同的方案，你只需要在Info.plist中声明你需要的东西。对于您可以包含多少计划似乎没有限制，但如果他们认为您滥用此机制，我会希望App Store审核团队提出问题。

Note that this mechanism only applies to canOpenURL and not openURL. You do not need to have a scheme listed in Info.plist to be able to open it with openURL.

NSString * msg = @"Application%20Name%20https://itunes.apple.com/in/app/myapp/id1054375332?ls=1&mt=8"; 

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 not installed." message:@"Your device has no WhatsApp installed." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; 
    [alert show]; 
}

如果使用 “[[UIApplication的sharedApplication]的OpenURL：whatsappURL];” 后弦replcement它会打开Safari浏览器没有的WhatsApp，

如果你想打开的WhatsApp不检查canOpenURL

failed for URL: "whatsapp://" - error: This app is not allowed to query for scheme whatsapp

当在iOS中9，你必须替换字符串

添加到您的Info.plist

<key>LSApplicationQueriesSchemes</key> 
    <array> 
     <string>whatsapp</string> 
    </array> 

，你需要打开WhatsApp的共享实现此代码到ViewController。 （例如像说一个按钮动作） 更新迅速版本3（Xcode的8.x中）：更新了弃用：

var str = "This is the string which you want to share to WhatsApp" 
str=str.addingPercentEncoding(withAllowedCharacters: (NSCharacterSet.urlQueryAllowed))! 
let whatsappURL = URL(string: "whatsapp://send?text=\(str)") 
if UIApplication.shared.canOpenURL(whatsappURL) { 
    UIApplication.shared.open(whatsappURL!, options: [:], completionHandler: nil) 
} else { 
    showAlert(message: "Whatsapp is not installed on this device. Please install Whatsapp and try again.") 
} 

这里showAlert（）是用于显示警报的自定义功能。
