我的应用程序使用 SearchGraphical 在应用程序中搜索注册用户......我的问题是，当我去做研究时，我会看到重复的结果：
名称搜索: Francesca 结果: Francesca (1 cell) Francesca (2 Cell)
**09/14/2013 22:18:17.817 Unipot v.02 [63396: a0b] Successfully retrieved 1 scores.
09/14/2013 22:18:17.818 Unipot v.02 [63396: a0b] Content: Antonella Folino
09/14/2013 22:18:17.818 Unipot v.02 [63396: a0b] Content: francesca Folino
09/14/2013 22:18:17.818 Unipot v.02 [63396: a0b] Content: francesca Folino
09/14/2013 22:18:17.819 Unipot v.02 [63396: a0b] Content: francesca Folino**
我不明白为什么。当您在搜索栏中快速完成键入时会出现此问题。
此外，应用程序会在短时间内返回此通知而崩溃：
**Terminating apt two to uncaught exception 'NSRangeException', reason: '*** - [__NSArrayM objectAtIndex:]: index 10 beyond bounds [0 .. 9] '**
这是我的文件。M 你能帮帮我吗？
