So you want a dialog box where the user can choose a directory? If so, then you actually want an NSOpenDialog. Set canChooseDirectories to true, and canChooseFiles and allowsMultipleSelection to false.

NSOpenDialog means NSOpenPanel

i use it like this

NSOpenPanel* openPanel = [NSOpenPanel openPanel];
		
		
		[openPanel setAllowsMultipleSelection:NO];
		[openPanel setCanChooseDirectories:YES];
		[openPanel setCanChooseFiles:NO];
		[openPanel setCanCreateDirectories:YES];
		[openPanel setTreatsFilePackagesAsDirectories:NO];
		[openPanel setResolvesAliases:YES];
			
		[openPanel beginSheetModalForWindow:controlPanel completionHandler:^(NSInteger result) 
		 {
			 if (result == NSOKButton) 
			 {
				 
				 [_path setStringValue:[openPanel filename]];
				 
				 
			 }
		 }];

here the problem is,if i create a folder on desktop and select that folder
than again open the NSOpenPanel after MoveToTrash the created folder,
now create the folder with same name on desktop,now Program received signal: “EXC_BAD_ACCESS”.

and point out here

#0 0x940ee6a2 in TFSInfo::AddPtrReference
#1 0x940ef7f2 in TNode::IsContainer
#2 0x94135bbb in TNode::SetForceSync

so please help me for this.

thanks.

I cannot reproduce your problem a test project under Mac OS X 10.7.2. I opened an NSOpenPanel, created a folder on my desktop and selected that folder. I then moved the newly created folder to the trash. When I opened the NSOpenPanel again, it reverted to my Documents folder. It didn't get an EXC_BAD_ACCESS signal.


BTW The NSOpenPanel's filename is deprecated. You should be using URLs instead of string paths.

Sorry again. I didn't pick up on that you were selecting a second newly created folder that happened to have the same path as the now trashed, previously selected folder. I tried that but again I didn't get an EXC_BAD_ACCESS signal.

Does the EXC_BAD_ACCESS occur as soon as as you click Create, or is it after you click Open?

 

[mkristain]

some time on click Create, or sometimes on click Open

why i receiving this every time,

is there any mistake in my method to open panel?

I've been using your code, with one difference.

Instead of your line:

[_path setStringValue:[openPanel filename]];

I have:

NSLog(@"Selected URL: %@", [openPanel URL]);

 

[mkristain]

i am using [_path setStringValue:[openPanel filename]]; because i display the selected path in this text field.
