searchDisplayController 時引起的數組越界，數組越界

當  [searchDisplayController.searchResultsTableView setSeparatorStyle:UITableViewCellSeparatorStyleNone] 時， 發送了崩潰

錯誤提示如下：

Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayI objectAtIndex:]: index 1 beyond bounds [0 .. 0]'*** First throw call stack:(0   CoreFoundation                      0x000000010c6c6c65 __exceptionPreprocess + 1651   libobjc.A.dylib                     0x000000010c35fbb7 objc_exception_throw + 452   CoreFoundation                      0x000000010c5bd17e -[__NSArrayI objectAtIndex:] + 1903   UIKit                               0x000000010d230fd2 -[UITableViewDataSource tableView:indentationLevelForRowAtIndexPath:] + 1064   UIKit                               0x000000010cdfb1b9 __53-[UITableView _configureCellForDisplay:forIndexPath:]_block_invoke + 1711

查了好久才查到原因： 在錯誤log中有提示

3   UIKit                               0x000000010d230fd2 -[UITableViewDataSource tableView:indentationLevelForRowAtIndexPath:] + 106

解決方案：

-(NSInteger)tableView:(UITableView *)tableView indentationLevelForRowAtIndexPath:(NSIndexPath *)indexPath{    return 0;}
