问题描述
我想刷新 Finder 应用程序中特定文件/文件夹的图标.
I want to refresh icon for particular file/folder in Finder application.
FNNotifyByPath( (const UInt8 *)folderPath, kFNDirectoryModifiedMessage, kNilOptions );
FNNotifyByPath
不适用于此.现在我正在尝试使用 appleScript
FNNotifyByPath
is not working for this.
Now i am trying with appleScript
+(void) refreshIconForItem : (NSString *)itemPath
{
NSString *source=[NSString stringWithFormat:@"tell application \"Finder\" to update \"%@\"",[NSString stringWithUTF8String:itemPath]];
NSAppleScript *update=[[NSAppleScript alloc] initWithSource:source];
NSDictionary *err;
[update executeAndReturnError:&err];
}
但是这个功能也不起作用.
but this function is also not working.
有人可以帮我吗?
推荐答案
executeAndReturnError:
调用后,您是否检查了 err
字典的值?
Did you check the value of the err
dictionary after the executeAndReturnError:
call?
正确的 AppleScript 语法是:
The correct AppleScript syntax would be:
@"告诉应用程序\"Finder\"更新POSIX文件\"%@\""
@"tell application \"Finder\" to update POSIX file \"%@\""
编辑添加:或者,您可以下拉到 AppleEvent 级别:
EDIT TO ADD: Alternately, you could drop down to the AppleEvent level:
OSStatus SendFinderSyncEvent( const FSRef* inObjectRef )
{
AppleEvent theEvent = { typeNull, NULL };
AppleEvent replyEvent = { typeNull, NULL };
AliasHandle itemAlias = NULL;
const OSType kFinderSig = 'MACS';
OSStatus err = FSNewAliasMinimal( inObjectRef, &itemAlias );
if (err == noErr)
{
err = AEBuildAppleEvent( kAEFinderSuite, kAESync, typeApplSignature,
&kFinderSig, sizeof(OSType), kAutoGenerateReturnID,
kAnyTransactionID, &theEvent, NULL, "'----':alis(@@)", itemAlias );
if (err == noErr)
{
err = AESendMessage( &theEvent, &replyEvent, kAENoReply,
kAEDefaultTimeout );
AEDisposeDesc( &replyEvent );
AEDisposeDesc( &theEvent );
}
DisposeHandle( (Handle)itemAlias );
}
return err;
}
