[操作系统]searchDisplayController 时引起的数组越界


当  [searchDisplayController.searchResultsTableView setSeparatorStyle:UITableViewCellSeparatorStyleNone] 时, 发送了崩溃

错误提示如下:

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: 在错误log中有提示

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

解决方法:

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