iOS 7.x的设备跳转AXWebViewController时，会出现闪退问题。

[wanderer9527]

打扰一下，请教一个问题，我在使用AXWebViewController作为显示载体时，在7.x的设备上会出现闪退问题，其他系统版本显示正常。还是说 我在7.x的设备使用AXWebViewController，需要做其他处理？？

@wanderer9527 是真机设备吧？

[wanderer9527]

没错，是在真机设备，iOS 7.1.2

[devedbox]

@wanderer9527 要不你帮忙看看什么原因吧？😆我没有iOS7的设备啊.

[devedbox]

@wanderer9527 再说现在iOS7都是古董了= =

[wanderer9527]

@devedbox 已经定位到问题了。 下面这个宏定义有点问题，在iOS7.x的设备，返回YES， __IPHONE_OS_VERSION_MAX_ALLOWED = 103000 这个应该是SDK版本号？？

ifndef AX_WEB_VIEW_CONTROLLER_USING_WEBKIT

define AX_WEB_VIEW_CONTROLLER_USING_WEBKIT IPHONE_OS_VERSION_MAX_ALLOWED >= IPHONE_8_0

endif

@wanderer9527 你看要不你提个pr上来呢？谢谢

[wanderer9527]

@devedbox 嘿嘿，不客气，我只是找到问题，没想到什么解决方法， 所以我目前从iOS8.x开始支持起，使用AXWeb.
