Question

嗨我有两个nsarrays。

数组A：

 arrProductSelection = [[NSArray alloc]initWithObjects:@"English",@"German",@"Russian",@"Chinese",@"Spanish",@"French",@"French",@"French",@"French",@"French",@"French",@"French",@"French",nil];

数组B：

arrProductSelectionB = [[NSArray alloc]initWithObjects:@"deselcted",@"selected",@"selected",@"selected",@"deselcted",@"deselcted",@"deselcted",@"deselcted",@"deselcted",@"deselcted",@"deselcted",@"deselcted",@"deselcted",nil];

我需要比较两个数组并通过比较具有所选值的数组B来从数组A获取值。那就是我应该用逗号作为nsstring将德语，中文和俄语分开。

Answer 1

试试这个：

//UNUserNotificationCenterDelegate delegate methods to get userInfo

    @available(iOS 10.0, *)
    func userNotificationCenter(_ center: UNUserNotificationCenter,  willPresent notification: UNNotification, withCompletionHandler   completionHandler: @escaping (_ options:   UNNotificationPresentationOptions) -> Void) {

        //Called when a notification is delivered to a foreground app.

        let userInfo = notification.request.content.userInfo as? NSDictionary
        print("\(userInfo)")

     }

    @available(iOS 10.0, *)
    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

        // Called to let your app know which action was selected by the user for a given notification.
        let userInfo = response.notification.request.content.userInfo as? NSDictionary
        print("\(userInfo)")
    }

Answer 2

首先我要确保两个阵列都有相同的安全计数器，如

ng-app

Answer 3

如果你可以制作这种类型的阵列，那么就可以轻松管理。

(
        {
        flag = deselcted;
        name = English;
    },
        {
        flag = selected;
        name = German;
    },
        {
        flag = deselcted;
        name = Russian;
    },
        {
        flag = deselcted;
        name = Chinese;
    }
)

==＆GT;阵列[（辞典），（词典），...]

Answer 4

如果你需要一个数组的结果，这是函数：

NSMutableArray*resultArray=[[NSMutableArray alloc]init];

    for(int i=0; i<arrProductSelectionB.count;i++){
        if ([[arrProductSelectionB objectAtIndex:i]isEqualToString:@"selected"]) {
            [resultArray addObject:[arrProductSelection objectAtIndex:i]];
        }
    }

resultArray有你需要的值。

如何比较两个具有不同值的nsarray？
