objective-c - 以编程方式添加搜索文本框作为 Cocoa 中的菜单项

Question

我想要一个像 iTunes 那样的搜索输入框。我有我的工具栏显示出来，我有下面的代码显示了一个自定义的toobaritem，它有正确的灰色描述，并以紫色显示文本“Fnurd..”，但文本不可编辑!这让我发疯，我做错了什么？

- (NSToolbarItem *)toolbar:(NSToolbar *)toolbar itemForItemIdentifier:(NSString *)itemIdentifier willBeInsertedIntoToolbar:(BOOL)flag
{
    NSToolbarItem *item = [[NSToolbarItem alloc] initWithItemIdentifier:itemIdentifier];

    if ( [itemIdentifier isEqualToString:@"SearchItem"] ) {

        //Land in sight !
        NSLog(@"### Setting up Search Item Menu Entry");        

        //Starter size
        NSRect cellFrame = NSMakeRect(0,0,200,25);
        //Create/allocate Control
        searchMenuControl = [[NSControl alloc] initWithFrame:cellFrame];
        //Create/allocate Cell
        searchMenuCell = [[NSTextFieldCell alloc] initTextCell:@"Fnurd.."];

        //Assign cell to control        
        [searchMenuControl setCell:searchMenuCell];

        //Do some polishing
        [searchMenuCell setBezelStyle:NSTextFieldRoundedBezel];
        [searchMenuCell setBackgroundColor:[NSColor whiteColor]];
        [searchMenuCell setTextColor:[NSColor blackColor]];     
        [searchMenuCell setEnabled:YES];
        [searchMenuCell setCellAttribute:NSCellEditable to:YES];


        cellFrame = [searchMenuControl frame];

        // Configuration code for "SearchItem"
        [item setLabel:@"Search Records"];
        [item setPaletteLabel:[item label]];
        [item setView:searchMenuControl];
        [item setMinSize:cellFrame.size];
        [item setMaxSize:cellFrame.size];       
    }

    return [item autorelease];
}

发布到 stackoverflow 是一件很神奇的事情，您一定会在 google 查询后找到答案..

Cocoa 基本上有一个您可以使用的搜索字段小部件..

- (NSToolbarItem *)toolbar:(NSToolbar *)toolbar itemForItemIdentifier:(NSString *)itemIdentifier willBeInsertedIntoToolbar:(BOOL)flag
{
    NSToolbarItem *item = [[NSToolbarItem alloc] initWithItemIdentifier:itemIdentifier];

    if ( [itemIdentifier isEqualToString:@"SearchItem"] ) {

        //Land in sight !
        NSLog(@"### Setting up Search Item Menu Entry");        

        searchField = [[NSSearchField alloc] init];
        [searchField sizeToFit];

        NSRect cellFrame = [searchField frame];

        // Configuration code for "SearchItem"
        [item setLabel:@"Search"];
        [item setPaletteLabel:[item label]];
        [item setView:searchField];
        [item setMinSize:cellFrame.size];
        [item setMaxSize:cellFrame.size];       
    }

    return [item autorelease];
}
