当用户想删除一个单元格时,我创建了一个更新我的UITableView的方法.
-(void)removeMoreFriendsRow:(NSNotification *)notification {
NSDictionary *d = [notification userInfo];
NSIndexPath *index = [d objectForKey:@"indexPath"];
[self.p_currentFriends removeObjectAtIndex:index.row];
[self.o_table deleteRowsAtIndexPaths:[NSArray arrayWithObject:index] withRowAnimation:UITableViewRowAnimationRight];
}

p_currentFriends是一个NSMutableArray,它包含UITableView打印的所有对象.
当我使用它一次时,此方法可以正常工作,但是当我多次使用它时它会失败.
似乎每次调用deleteRowsAtIndexPaths时indexPath都保持不变.
例如, - 在第一次调用时,用户点击第二个单元格,indexPath = [0,1]并删除正确的单元格 - 在第二次调用时,用户点击第三个单元格并且indexPath = [0, 3]而不是[0,2]
/*希望我足够清楚:/*/
我发现使其工作的唯一方法是使用reloadData,但我希望在删除单元格时有动画.
有没有人有解决方案或提示?
我在使用带有UITableView的UISearchDisplayController时有一个僵尸.
UISearchDisplayController(以及视图的其余部分)是通过界面构建器设置的(xcode 5上的故事板,仅使用ARC和iOS 7).
searchDisplayController由这两种方法使用
-(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString {
[self filterContentForSearchText:searchString scope:
[[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:[self.searchDisplayController.searchBar selectedScopeButtonIndex]]];
return YES;
}
-(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchScope:(NSInteger)searchOption {
[self filterContentForSearchText:self.searchDisplayController.searchBar.text scope:
[[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:searchOption]];
return YES;
}
