How to use sheets on Yosmite 10.10 and above.
Sheets are easy to use. However, it wasn't initially obvious how.
Launch the sheet and control the repsonse using the following code:
[[self window] beginSheet:self.sheetWindowController.window completionHandler:^(NSModalResponse returnCode) {
switch (returnCode) {
case NSModalResponseCancel:
NSLog(@"%@", @"NSModalResponseCancel");
break;
case NSModalResponseOK:
NSLog(@"%@", @"NSModalResponseOK");
break;
default:
break;
}
}];
Dismiss the sheet with one of the following model responses, you might want to do this using action methods assigned to your OK and Cancel buttons,
- (IBAction)cancelButtonAction:(id)sender {
[[[self window] sheetParent] endSheet:self.window returnCode:NSModalResponseCancel];
}
- (IBAction)OKButtonAction:(id)sender {
[[[self window] sheetParent] endSheet:self.window returnCode:NSModalResponseOK];
}
