objective-c - 如何打开文件/目录获取信息窗口？

Question

有没有办法以编程方式在我的应用程序中为某些路径打开 Finder 的“获取信息”窗口？

Answer 1

还有一个简单的解决方案，你可以在苹果的“图片搜索”项目中看到。

以下代码可用于根据示例显示单个文件的“获取信息”窗口。

- (void)infoButtonAction:(NSOutlineView *)sender {
    // Access the row that was clicked on and open that image
    NSInteger row = [sender clickedRow];
    SearchItem *item = [resultsOutlineView itemAtRow:row];
    // Do a "reveal" in finder
    if ([item filePathURL]) {
        NSPasteboard *pboard = [NSPasteboard pasteboardWithUniqueName];
        [pboard declareTypes:[NSArray arrayWithObject:NSStringPboardType] owner:nil];
        [pboard setString:[[item filePathURL] path]  forType:NSStringPboardType];
        NSPerformService(@"Finder/Show Info", pboard);
    }
}

我根据需要进一步修改了代码，以显示多个文件的对话框，如下所示:

NSPasteboard *pboard = [NSPasteboard pasteboardWithUniqueName];
[pboard declareTypes:[NSArray arrayWithObject:NSStringPboardType] owner:nil];

NSMutableArray *fileList = [NSMutableArray new];

//Add as many as file's path in the fileList array
for(FileItem *item in fileItems) {
    [fileList addObject:[[item.filePath filePathURL] path]];
}

[pboard setPropertyList:fileList forType:NSFilenamesPboardType];
NSPerformService(@"Finder/Show Info", pboard);

希望这会有所帮助，仅供引用，这将适用于 Lion 及更高版本中的沙盒应用程序。
