tableView 删除小技巧

//滑动删除

-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath

{  

    NSUInteger row = [indexPath row];

    [bookInforemoveObjectAtIndex:row];//bookInfo为当前table中显示的array

    [tableView deleteRowsAtIndexPaths:[NSArrayarrayWithObject:indexPath]withRowAnimation:UITableViewRowAnimationLeft];

}

 

/*此时删除按钮为Delete，如果想显示为“删除” 中文的话，则需要实现

UITableViewDelegate 中的- (NSString *)tableView:(UITableView *)tableView titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath方法*/

 

- (NSString *)tableView:(UITableView *)tableView titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath{   

    return @"删除";   

}   

//或者，最简单的方式，将plist中的Localization native development region改为China即可

 

//这只是让默认的Delete按钮显示成了中文的删除按钮而已，如果想将这个删除按钮换成其他图片形式的，怎么办呢？
