我想在光标的插入点插入标记，而不是数组的末尾

我有一个将令牌添加到 NSTokenField 的按钮。它将标记始终添加到字段的末尾：

NSTokenField *currentField = [sender representedObject];

    // Determine which token should be inserted into the field using the tag of the sender.
    switch( [sender tag] )
    {
        case eFileNameToken_StartDate:
            [currentField setObjectValue:[[currentField objectValue] arrayByAddingObject:[NSMutableDictionary dictionaryWithObjectsAndKeys:kTokenName_StartDate, kTokenKey_Name, @"%m-%d-%Y", kTokenKey_Format, [NSNumber numberWithInt:0], kTokenKey_FormatIndex, nil]]];
            break;

因为它从 currentField objectValue 中获取数组，然后通过添加对象来创建数组。

我想让它知道光标的插入点并将对象插入到生成的 currentField objectValue 中，以便我可以使用正确排序的标记来设置 currentField 的ObjectValue。感谢你们的帮助

I have a button that adds a token to a NSTokenField. It adds the token always to the end of the field:

NSTokenField *currentField = [sender representedObject];

    // Determine which token should be inserted into the field using the tag of the sender.
    switch( [sender tag] )
    {
        case eFileNameToken_StartDate:
            [currentField setObjectValue:[[currentField objectValue] arrayByAddingObject:[NSMutableDictionary dictionaryWithObjectsAndKeys:kTokenName_StartDate, kTokenKey_Name, @"%m-%d-%Y", kTokenKey_Format, [NSNumber numberWithInt:0], kTokenKey_FormatIndex, nil]]];
            break;

Because it is grabbing the array from the currentField objectValue and then creating an array by adding the object.

I would love to have it know the insertion point of the cursor and insert the object into the resulting currentField objectValue so that I can then setObjectValue of the currentField with the correctly ordered tokens.
Thanks for any help yall

所以我想通了，我想我应该分享我的解决方案。

需要获取 fieldEditor 并检查其 selectedRange。

NSText *textEditor = [currentField currentEditor];

这将为您提供当前编辑的文本字段中的插入点。但是，如果您有一个将文本和标记混合在一起的 tokenField，那么您会发现每个标记仅算作 selectedRange 中的一个字符。

如果是这种情况，那么您需要编写一些逻辑来正确插入到 currentField 数组中。

步骤：
1. 创建一个临时 NSMutableArray
2. 用 [currentField objectValue] 填充该值
3. 迭代此临时数组，递增位置计数器 1
  对于种类标记的类别，1 表示
  非标记字符串中的每个字符
4. 在每个循环结束时增加数组索引
5. 确保检查位置计数器是否等于或大于
  比你的 [currentFieldEditor
  selectedRange].location 并中断
  跳出循环
6. 最后将新令牌插入临时数组中，然后
  [currentField setObjectValue: 与
  该数组]

我的令牌以逗号分隔并以 $token$ 样式名称推入 NSDictionaries 中
这就是我在运行循环时划分文本和标记的方式。

快乐的：）

So I figured it out and I thought Id share my solution.

One needs to grab the fieldEditor and check its selectedRange.

NSText *textEditor = [currentField currentEditor];

This gives you the insertion point in the currently edited text field. However if you have a tokenField that has text and tokens mixed together then you will find that each token only counts as one character in the selectedRange.

If this is the case then you need to write some logic to correctly insert into the currentField array.

Steps:
1. make a temp NSMutableArray
2. fill that with the [currentField objectValue]
3. iterate through this temp array, incrementing a postion counter, 1
  for classes of kind token, 1 for
  each character in a non token string
4. at the end of each loop increment your array index
5. make sure to check if the positioncounter is equal or greater
  than your [currentFieldEditor
  selectedRange].location and break
  out of the loop
6. Finally insert your new token into the temp array and then
  [currentField setObjectValue: with
  that array]

My tokens are comma delinated and shoved into NSDictionaries with $token$ style names
This is how I delineate between text and tokens when I run my loop.

happy :)
