"Save As" in non-document based application Cocoa
This is pretty straightforward. You tagged this question with NSSavePanel and that's exactly what you want to use.
- (IBAction)showSavePanel:(id)sender{ NSSavePanel * savePanel = [NSSavePanel savePanel]; // Restrict the file type to whatever you like [savePanel setAllowedFileTypes:@[@"txt"]]; // Set the starting directory [savePanel setDirectoryURL:someURL]; // Perform other setup // Use a completion handler -- this is a block which takes one argument // which corresponds to the button that was clicked [savePanel beginSheetModalForWindow:someWindow completionHandler:^(NSInteger result){ if (result == NSFileHandlingPanelOKButton) { // Close panel before handling errors [savePanel orderOut:self]; // Do what you need to do with the selected path } }];}See also "The Save Panel" in the File System Programming Guide.
