将Applescript移植到Scripting Bridge:无法在Excel 2008中获取范围值

Question

我需要将一些Applescript代码移动到Scripting Bridge，以便在不需要Applescript-ObjC的情况下利用一些Cocoa挂钩。

使用带有Applescript的Excel 2008，很容易获得一个范围的值：

set myList to GetValuesFromColumnRange("A", 1, 100)

 on GetValuesFromColumnRange(ColumnLetter, FirstRow, LastRow) -- (string, integer, integer) as list
     set theList to {}
     tell application "Microsoft Excel"
         set theRange to ColumnLetter & FirstRow & ":" & ColumnLetter & LastRow
         set AppleScript's text item delimiters to {return}
         set theList to (get value of range theRange as list)
         set AppleScript's text item delimiters to {""}
     end tell
     set theList to ConvertItemizedListToValueList(theList) of me -- Note this dependency due to how MSE2008 returns the data
     return theList
 end GetValuesFromColumnRange

但是在Scripting Bridge中，我在获取基于范围的工作表的单元格时遇到了问题。以下是我到目前为止所掌握的。

    Excel2008Application *excelApp = [SBApplication applicationWithBundleIdentifier:@"com.microsoft.Excel"];

    Excel2008Workbook *workbook = excelApp.activeWorkbook;

    SBElementArray *sheets = [workbook sheets];

    Excel2008Sheet *targetSheet;
    int thisSheet = 0;
    int lastSheet = [sheets count]; 

    for (thisSheet = 0; thisSheet < lastSheet; thisSheet++) {
        Excel2008Sheet *currentSheet = [sheets objectAtIndex:thisSheet];
        NSString *currentSheetName = currentSheet.name;
        if ([currentSheetName isEqualToString:@"Metadata"]) {
            targetSheet = currentSheet;
            [targetSheet retain];
        }
    }

    Excel2008Range *range = [[[excelApp classForScriptingClass:@"range"] alloc] initWithProperties:[NSDictionary dictionaryWithObjectsAndKeys:@"A1:A10", @"formulaR1c1", nil]];

    [[targetSheet ranges] addObject:range];
    range = [[targetSheet ranges] lastObject]; // not null; stated class in log: MicrosoftExcelRange

    Excel2008Sheet *valueSheet = range.worksheetObject; // supposed to be new worksheet based upon values within the range; not null; stated class in log: MicrosoftExcelSheet
    [valueSheet retain];

    SBElementArray *valueCells = [valueSheet cells]; // not null, but count is 0
    [valueCells retain];

当我实际从valueSheet获取单元格时，最后一行出现了问题，因为返回的SBElementArray不是null，但它也不包含任何对象。同样的道理也适用于在targetSheet中获取单元。

从我所有的搜索来看，几乎不存在这样做的文档，我已经尽我所能地做了这件事。

解决了。

NSString *rangeName = @"A1:A10";

Excel2008Range *range = [[[excelApp classForScriptingClass:@"range"] alloc] initWithProperties:[NSDictionary dictionaryWithObjectsAndKeys:rangeName, @"name", nil]];
[[targetSheet ranges] addObject:range];

Excel2008Range *currentRange;
if ([[[targetSheet ranges] objectWithName:rangeName] exists]) {
    currentRange = [[targetSheet ranges] objectWithName:rangeName];
}

NSLog(@"[currentRange.value get] = %@", [currentRange.value get]);
// result: ((key),(1),(2),(3),(4),(5),(6),(7),(8),(9)) = NSArray

诀窍似乎是将范围字符串设置到Excel2008Range的name属性中。在处理这个问题时，我发现了一个陷阱，那就是永远不会填充范围的formulaR1c1 -就像在[NSDictionary dictionaryWithObjectsAndKeys:rangeName, @"formulaR1c1", nil]-because中一样，它将使用范围字符串的值填充范围。

事后看来，当在两个Applescript中读取完全相同的命令的语法时，这实际上是有意义的。

tell application "Microsoft Excel"
    set theValues to get value of range "A1:A10"
end tell

...and objc-appscript...

NSString *rangeString = @"A1:A10"
MEApplication *microsoftExcel = [MEApplication applicationWithName: @"Microsoft Excel"];
MEReference *cells = [[[microsoftExcel ranges] byName:rangeString] value];
NSArray *cellValues = [cells getItem];

在这两种情况下，范围的值都是通过获取带有其名称的值的范围来获得的。但是使用Scripting Bridge，我可以说，名称必须在创建range对象时显式地应用。

我确信有更好的方法来实现这一点(通常是有的)，但至少这是可行的。
