我的代码（EasyTableView.m：291）如下所示

- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
    if ([delegate respondsToSelector:@selector(easyTableView:scrolledToOffset:)])
        [delegate easyTableView:self scrolledToOffset:self.contentOffset];
}

- (CGPoint)contentOffset {
    CGPoint offset = self.tableView.contentOffset;

    if (_orientation == EasyTableViewOrientationHorizontal)
        offset = CGPointMake(offset.y, offset.x);

    return offset;
}


- (void)setContentOffset:(CGPoint)offset {
    if (_orientation == EasyTableViewOrientationHorizontal)
        self.tableView.contentOffset = CGPointMake(offset.y, offset.x);
    else
        self.tableView.contentOffset = offset;
}

我尝试使用Zombie进行调试并查看了仪器泄漏。但我找不到任何东西。我该如何解决这个问题？提前致谢

Answer 1

您应该清除scrollView

中的tableView和dealloc代表

Answer 2

在斯威夫特：

deinit {
   self.scrollView.delegate = nil
   self.tableView.delegate = nil
}
