MacApp 开发，添加的 NSTextView 无法滚动，显示不全？求大佬指点 https://github.com/shang1219178163/MacTemplet.git

-(NSTextView *)textView{
    if (!_textView) {
        _textView = ({
            NSTextView * view = [[NSTextView alloc]init];
//            view.autoresizingMask = NSViewWidthSizable | NSViewHeightSizable;
            
            view.horizontallyResizable = false;
            view.verticallyResizable = true;
            view.maxSize = CGSizeMake(FLT_MAX, FLT_MAX);
//            view.textContainer.containerSize = NSMakeSize(FLT_MAX, FLT_MAX);
            view.textContainer.widthTracksTextView = true;
            view.autoresizingMask = NSViewWidthSizable;

            view.delegate = self;
            view.backgroundColor = NSColor.yellowColor;
            view.selectable = true;
            view.drawsBackground = true;
            
            view.font = [NSFont systemFontOfSize:17];
            view.string = @"NSScrollView 上无法滚动的 NSTextView";
            
            view;
        });
    }
    return _textView;
}
