Swift(iOS 9 Xcode7)   一个app打开另一个

两个app： Test 和 BasicGrammar

目的：从Test app 中打开 BasicGrammar app内指定的某个页面，并传参数过去：

---

BasicGrammar：

配置info.plist AppDelegate

 func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {
        
        //这里进行判断是哪一个app在打开此app，然后分别进行操作
        let scheme = url.scheme
        //不分大小写比较
        if scheme.caseInsensitiveCompare("OpenAppTest") == .OrderedSame{
        
            //执行跳转，跳转到你想要的页面
            let alert = UIAlertView(title: "\(scheme)", message: "\(url)", delegate: self, cancelButtonTitle: "确认")//iOS, introduced=2.0, deprecated=9.0
            alert.show()
            
            let vc = NextViewController()
            if let navVC = self.window?.rootViewController as? UINavigationController{
                navVC.pushViewController(vc, animated: true)
            }
            
        
            return true
            
        }
        
        return true
    }

Test：

记得设置info.plist里面的LSApplicationQueriesSchemes，iOS9之后需要，iOS9之后提高了app的安全性，需要给出一个类似白名单的东西，在白名单里面的才能打开app。不然报错： -canOpenURL: failed for URL: "OpenAppTest://mark?id=007" - error: "This app is not allowed to query for scheme OpenAppTest"

func openAppButton(){
    
        let button = UIButton()
        self.view.addSubview(button)//(必须要先把button加进来，才可以用去写它的布局)erminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'couldn't find a common superview for <UIButton: 0x136682f20; frame = (0 0; 0 0); opaque = NO; layer = <CALayer: 0x136682e70>> and <UIView: 0x136683900; frame = (0 0; 414 736); autoresize = W+H; layer = <CALayer: 0x136682be0>>'*** First throw call stack:

        //OpenAppTest://mark?id=xxxx   (调用BasicGrammar app 拼接参数字符串，拼接的时候就像url那样子  OpenAppTest://标记名字?name＝xiaomin&age＝23)
