我有一个名为[self.places objectAtIndex:indexPath.row]的数组; 我试图输出到表中.数组中充满了对象,但是我想使用对象内部的数据,将它们分配给对象的最佳方法是什么？数组内部的数据如下:

<Place:eXMSFqDg7B> {
    Location = "<PFGeoPoint: 0x6887480>";
    addressline1 = "address line 1";
    addressline2 = "address line 2";
    agerestrictions = "18+";
    email = "test@aol.com";
    image = "<PFFile: 0x6887af0>";
    name = "Rain NightClub";
    phone = 0123456789;
    postcode = BT11TG;
    type = Club;
}

    Location = "<PFGeoPoint: 0x6888330>";
    addressline1 = "address line 1";
    addressline2 = "address line 2";
    agerestrictions = "18+";
    email = "test@aol.com";
    image = "<PFFile: 0x6888950>";
    name = "Box NightClub";
    phone = 0123456789;
    postcode …

我有一个循环的XML文件集合,并将有错误的文件移动到另一个文件位置.但是,当我使用system.io.file.move函数时,它需要我指定文件名而不是移动文件路径.有没有办法可以将文件从一个位置移动到另一个位置,同时保持相同的名称？我目前正在根据数组中文件的位置创建一个名称,这是不可行的.

string ErrorPath = string.Format(@"{1}ErroredXml{0}.xml", errorLength, errorPaths);

//If type equals "add" then call add method else call update
if (Equals(type, typecomp))
{
    //pass object to data access layer to add record
    value.addNewGamePlay();

    if (value.getGamePlayID() == 0)
    {
        //move to error file
        System.IO.File.Move(value.getFile(), ErrorPath);
        errorLength++;
    }
}

我试图使用Arrays.binarySearch()方法在字符串数组中找到字符串的索引,但是当查找字符串"Free"时,该方法似乎返回位置整数"-5".知道为什么会这样吗？

String[] names = {"Arken","Ben","Darklark", "Free","group"};

void changeFriends(String uname, boolean b)
        {   // change a friend's "online" status

    Arrays.sort(names);
    int index = Arrays.binarySearch(names, uname);

    System.out.println("NAME OF ONLINE USER IS AT INDEX:" + index + "Name:" + uname);
        if(index > -1)
        {

             if(b == true)
            {
                loggedOn[index] = true;
            }
            else
            {
                loggedOn[index] = false;
            }
        }
        // call method to update buttons
        changeNameButtons();
    }

我正在尝试使用数组和array.BinarySearch函数验证密码和用户名.数组中的前两个用户名:bradley和john使用函数0和1返回正确的位置.但是当我尝试验证数组jim和clarke中的最后两个字符串时,binarySearch函数返回的用户名位于数组中的位置-2两次导致验证失败.有任何想法吗？

 String[] names = {"bradley","john","jim","clarke"};
    String[] passwords = {"password","password","test","test"};
    int pos = Arrays.binarySearch(names, uname);
                    System.out.println("Found you in array:" + uname + "here:" + pos);
                    if(pos >= 0)
                    {   
                        System.out.println("Validation password for:" + uname);
                        if(passwords[pos].equals(pword) && !loggedOn[pos])
                        {
    }
