在日常的开发中我们都会遇到这样的一个需求，就是在当前控制器里面弹出一个提示框，如下面的图。

如果只是弹出一个框只是用于显示的话。就是框里面不用进行点击操作的话，就简单了。我们可以自定义一个view 我之前是添加到win里面的，为什么添加到win，目的就是想整个屏幕显示。如果添加到控制器的view里面的话，控制器有系统自带的导航栏，view不会覆盖住导航栏，就显得不好看，所以就加到win里面去。

但是如果，view里面还有还有点击的操作跳转到其他去，例如下面的需求

如果添加到win里面去进行跳转最好用模态弹出（Modal）方法去跳转不回影响界面效果，例如：下面的图片效果

但是这种需求局限于 界面弹出来是用于看的，如果需求弹出的是登录页面，登录页面又要出注册页面，而等于页面本身是用push去注册页面的这样就麻烦了，入下面的图片

如果添加到win的话 用push跳转回出现不好修复的BUG 如果添加到view的话解决跳转的问题，控制器有系统自带的导航栏，view不会覆盖住导航栏，就显得不好看。

其实解决这个办法。还是要添加到控制器的view里面去的，我们把系统自定的导航栏，隐藏它，改为自定义的导航栏，其实就是一个自定义的view，这样子就能解决问题，覆盖全屏，跳转就没有问题。
