iphone - 如何打开 iPhone 的默认浏览器？

Question

我在我的 iPhone 应用程序中放置了一个 Facebook 按钮。单击该按钮并加载 Facebook 登录页面时如何打开 iPhone 的默认浏览器？

Answer 1

iOS 10 引入了打开 URL 的新方法，如下所示:

swift 3:

let url = URL(string:"http://www.booleanbites.com")!
if #available(iOS 10.0, *) {
    UIApplication.shared.open(url, options: [:], completionHandler: nil)
} else {
    // Fallback on earlier versions
    UIApplication.shared.openURL(url)
}

objective-c :

NSURL *url = [NSURL URLWithString:@"http://www.booleanbites.com"];

if ([[UIApplication sharedApplication] respondsToSelector:@selector(openURL:options:completionHandler:)]) {
    [[UIApplication sharedApplication] openURL:url options:@{} completionHandler:NULL];
}else{
    // Fallback on earlier versions
    [[UIApplication sharedApplication] openURL:url];
}
