使用Cocoa为文件夹创建图标 [英] Using Cocoa to create an icon for a folder
问题描述
在我的Mac OS应用程序中,我提示用户创建一个新文件夹。我想在创建时使用Cocoa将一个图标应用于此文件夹。目前,要创建该文件夹,我使用以下代码:
In my Mac OS application, I'm prompting a user to create a new folder. I would like to apply an icon to this folder using Cocoa when it is created. Currently, to create the folder, I'm using the following code:
- (IBAction)browseFiles:(id)sender
{
NSOpenPanel *oPanel = [[NSOpenPanel openPanel] retain];
[oPanel setCanChooseDirectories:YES];
[oPanel setCanChooseFiles:NO];
[oPanel setDelegate:self];
[oPanel setCanCreateDirectories:YES];
[oPanel beginSheetForDirectory:NSHomeDirectory()
file:nil
types:nil
modalForWindow:nil
modalDelegate:self
didEndSelector:@selector(filePanelDidEnd:
returnCode:
contextInfo:)
contextInfo:nil];
}
选择目录后,用户点击一个调用函数的确认按钮以下方法:
After choosing a directory, the user clicks a confirm button that calls a function with the following method:
bool set = [[NSWorkspace sharedWorkspace] setIcon:[NSImage imageNamed:@"icon.icns"] forFile:path options:NSExcludeQuickDrawElementsIconCreationOption];
虽然上面的代码确实返回YES,但图标未成功应用于文件夹。我在代码中做错了吗?
While the piece of code above does return "YES", the icon is not successfully applied to the folder. Am I doing something wrong in my code?
谢谢。
推荐答案
NSWorkspace
方法就像魅力一样。也许您的图标格式无效?
我尝试 setIcon:
使用Finder图标:
The NSWorkspace
method works like a charm here. Maybe your icon is in an invalid format?
I tried setIcon:
using the Finder icon:
- (IBAction)setFolderIcon:(id)sender
{
NSOpenPanel* openPanel = [NSOpenPanel openPanel];
[openPanel setCanChooseFiles:NO];
[openPanel setCanChooseDirectories:YES];
switch([openPanel runModal])
{
case NSFileHandlingPanelOKButton:
{
NSURL* directoryURL = [openPanel directoryURL];
NSImage* iconImage = [[NSImage alloc] initWithContentsOfFile:@"/System/Library/CoreServices/Finder.app/Contents/Resources/Finder.icns"];
BOOL didSetIcon = [[NSWorkspace sharedWorkspace] setIcon:iconImage forFile:[directoryURL path] options:0];
NSLog(@"%d", didSetIcon);
[iconImage release];
}
case NSFileHandlingPanelCancelButton:
{
return;
}
}
}
