以上是ios4.1系统报的一个崩溃，请问有没有高手遇到过此问题，或有相关的想法，烦告之，不胜感激。
（其它系统基本无此问题；程序中没用到CommonToolsView）
------解决方案--------------------
unrecognized selector sent to instance 没有那个方法名
这种问题在debug环境下很容易就看到是哪句引起的
------解决方案--------------------
[CommonToolsView onClickCellBtn:]
全局搜索看看这个方法都在哪儿调用了,看看有没有可能找到线索
------解决方案--------------------
CommonTools这是 91桌面的库， 用户装了91桌面后，在4.x的设备上可能通过 “退出当前程序” 来直接退出当前程序，退出时，就会产生一条上面的crash log，是91桌面的bug
