Run an NSAlert Sheet in your Cocoa App

Published in: Objective C 

This code runs an alert sheet in your Cocoa app. You first create an NSAlert object, its properties, and define the method that should be called when the user dismisses the sheet. Then write the corresponding handler that tests for an "OK" or "Cancel" button press.


Plain TextExpand 
  1. NSAlert *alert = [[[NSAlert alloc] init] autorelease];
  2. [alert addButtonWithTitle:@"OK"];
  3. [alert addButtonWithTitle:@"Cancel"];
  4. [alert setMessageText:@"Sheet Title"];
  5. [alert setInformativeText:@"Message text goes here."];
  6. [alert setAlertStyle:NSWarningAlertStyle];
  7. [alert beginSheetModalForWindow:mainWindow modalDelegate:self didEndSelector:@selector(someMethodDidEnd:returnCode:contextInfo:) contextInfo:nil];
  8.  
  9. - (void) someMethodDidEnd:(NSAlert *)alert returnCode:(int)returnCode contextInfo:(void *)contextInfo
  10. {
  11. 	if(returnCode == NSAlertFirstButtonReturn)
  12. 	{
  13. 		// Do something
  14. 	}
  15. }
