Question

我想从URL和URL打开我的iOS应用程序，但是当我将NSURL放入资金申请时，print（）无法正常工作。

请参考这里

public static void main(String[] args) {
    long start = System.currentTimeMillis();

    Stream<Container> s = Stream.from(new Iterator<Container>() {
        int i = 0;

        @Override
        public boolean hasNext() {
            return i < 10000000;
        }

        @Override
        public Container next() {
            return new Container(i++);
        }
    });

    s = s.map((Container _source) -> new Container(_source.value * 2));

    int j = 0;
    while (s.hasNext()) {
        s.next();
        j++;
    }

    System.out.println(System.currentTimeMillis() - start);

    System.out.println("j:" + j);
}

public static class Container {

    int value;

    public Container(int v) {
        value = v;
    }

}

没有具有该签名的AppDelegate方法，因此不会被称为

func application(_ application: UIApplication, openURL url: NSURL, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool

正确的方法签名是：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool`

你对此方法感到困惑

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool

修改要响应从网络到iOS的链接，请使用

func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([Any]?) -> Void) -> Bool {

Appdelegate print（）不起作用
