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？
