ios - Swift:点击 UIButton 时如何打开新应用程序

Question

我有一个应用程序，当点击一个 ui 按钮时，我想打开另一个已安装的应用程序(即 Waze)。我该怎么做？非常感谢。

Answer 1

试试这个。例如你想打开一个 Instagram 应用程序:

let instagramHooks = "instagram://user?username=johndoe"
let instagramUrl = URL(string: instagramHooks)!
if UIApplication.shared.canOpenURL(instagramUrl)
{  
    UIApplication.shared.open(instagramUrl)
} else {
    //redirect to safari because the user doesn't have Instagram
    UIApplication.shared.open(URL(string: "http://instagram.com/")!)
}
