Sometime I get this strange log when I add a button at NSDocument's savePanel to close app after save operation end. This log surprise me! How can I solve it? Or How can I use cocoa’s save panel for have a @"Don't Save" button?

- (BOOL)prepareSavePanel:(NSSavePanel *)savePanel {
    if (self.noNeedSave) {
        NSButton * aBtn = [NSButton new];
        [aBtn setButtonType:NSMomentaryLightButton];
        [aBtn setBezelStyle:NSRoundedBezelStyle];
        [aBtn setFrame:NSMakeRect(40, 10, 100, 24)];
        [aBtn setAction:@selector(closeWindowNoSave)];
        [aBtn setTarget:self];
        [aBtn setTitle:@"Don't Save"];
        [aBtn setAlignment:NSCenterTextAlignment];
        [savePanel.contentView addSubview:aBtn];
    }
    return YES;
}
Solution

  • Finally I found the "Don't Save" button of save panel of document. Change the action to use my method for close window and don't save.
