我想打开具有多个图像选择功能的图库，我正在使用以下代码。

        Intent intent = new Intent();
        intent.setType("image/*");
        intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
        intent.setAction(Intent.ACTION_GET_CONTENT);
        startActivityForResult(Intent.createChooser(intent,"Select Picture"), 1);

它打开图库应用程序，但不允许我选择多个图像。

我想在recyclerview项目上实现onClickListener.这是我的CustomAdapter.kt代码.

package com.png.kotlinsample

import android.support.v7.widget.RecyclerView
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import android.widget.TextView

/**

class CustomAdapter(val userList: ArrayList<User>, val listener: (User) -> Unit) : RecyclerView.Adapter<CustomAdapter.ViewHolder>() {

    //this method is returning the view for each item in the list
        class MyAdapter(val userList: ArrayList<User>)
    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): CustomAdapter.ViewHolder {
        val v = LayoutInflater.from(parent.context).inflate(R.layout.row_layout, parent, false)
        return ViewHolder(v)
    }

    //this method is binding …

我正在尝试使用segue在视图控制器之间进行转换.它正确导航但运行了两次.

这是我的代码:

- (IBAction)onActionNext:(id)sender {
    if ([[nameField.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]]isEqualToString:@""]) {

    }else if([[emailField.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]] isEqualToString:@""]){

    }else if([[mobileField.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]] isEqualToString:@""]){

    }else{
        [self performSegueWithIdentifier:@"VerifyNext" sender:sender];
    }
}


- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
    if ([[segue identifier] isEqualToString:@"VerifyNext"]) {

        // Get destination view
        OTPSceneViewController *vc = [segue destinationViewController];
        [vc setTitle:@"myapp"];
    }
}

UNUserNotificationCenterDelegate从后台删除时不起作用。当应用程序停留在前台和后台时，它工作正常。

这是代码

extension AppDelegate: UNUserNotificationCenterDelegate {

    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        completionHandler([.alert, .sound])
    }

    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {


        let rootViewController = self.window!.rootViewController as! UINavigationController
        let mainStoryboard = UIStoryboard(name: "Main", bundle: nil)
        let profileViewController = mainStoryboard.instantiateViewController(withIdentifier: "SampleViewController") as! SampleViewController
        rootViewController.pushViewController(profileViewController, animated: true)

        completionHandler()
    }
}

当应用程序从后台删除时，不会调用委托方法。请帮帮我
