什么是崩溃日志？ 2016-12-15 13:02:10.836 AffordPlan[2884:91271] *** 由于未捕获的异常“NSUnknownKeyException”而终止应用程序，原因：“[name是什么？

您的崩溃日志说方法中谓词的键值存在问题
- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope
放置断点，检查代码运行时间并根据数据源更正谓词。
【讨论】：
我的应用程序在 - (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope method : arrsearchresult = [arrfullname filteredArrayUsingPredicate:resultPredicate]; 我更改了谓词的键值。现在我得到了这个错误日志。以上是关于当我在搜索栏中输入时，我的应用程序崩溃了的主要内容，如果未能解决你的问题，请参考以下文章
