推荐答案

如果您要检查的应用程序已注册了URI方案，您可以进行探测，并假设该应用是安装。看看 - （BOOL）canOpenURL：（NSURL *）网址，尝试一下

If the app you're checking for has a URI scheme registered, you can probe for that and assume the app is installed. Have a look at -(BOOL)canOpenURL:(NSURL *)url, try something along the lines of

if ( [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"fb://"]] )
{
     NSLog(@"will open facebook urls");
}

然而，这并不保证正版Facebook应用会响应fb：//

However, this does not give the guarantee that the genuine facebook app will respond to fb://
