常用代码

UITableView

#pragma mark - 设置分割线为屏幕宽度
-(void)viewDidLayoutSubviews{
    [super viewDidLayoutSubviews];
    if ([self.tableView respondsToSelector:@selector(setSeparatorInset:)]) {
        [self.tableView setSeparatorInset:UIEdgeInsetsZero];
    }
    if ([self.tableView respondsToSelector:@selector(setLayoutMargins:)]) {
        [self.tableView setLayoutMargins:UIEdgeInsetsZero];
    }
}
-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath{
    
    if ([cell respondsToSelector:@selector(setSeparatorInset:)]) {
        cell.separatorInset = UIEdgeInsetsMake(0, 0, 0, 0);
    }
    
    if ([cell respondsToSelector:@selector(setLayoutMargins:)]) {
        cell.layoutMargins = UIEdgeInsetsZero;
    }
}

侧滑返回执行协议方法

- (void)viewDidDisappear:(BOOL)animated
{
    [super viewDidDisappear:animated];
    if (![self.navigationController.viewControllers containsObject:self])//等效[self.navigationController.viewControllers indexOfObject:self] == NSNotFound
    {
      //自定义实现协议方法
       // [self executeDelegateMethods];
    }
}
