1、升级到iOS16的小伙伴会发现一个问题CPU直接100%，啥也没干啊

经过挨个测试发现是导航栏根据title初始化一个按钮导致的，在UIBarButtonItem+Category扩展中新增这个方法覆盖原来的方法

- (instancetype)initWithTitle:(NSString*)title style:(UIBarButtonItemStyle)style target:(id)target action:(SEL)action{

    UIButton * btn = [UIButton buttonWithType:UIButtonTypeCustom];

    [btn setTitle:title forState:UIControlStateNormal];

    [btn setTitleColor:UIColor.blueColor forState:UIControlStateNormal];

    [btn addTarget:target action:action forControlEvents:UIControlEventTouchUpInside];

    [btn sizeToFit];

    return [[UIBarButtonItem alloc] initWithCustomView:btn];

}
