Ios IndExpathForVisibleRows包含不正确的行计数

我有一个带有tableView的viewController。在6s+上，5行是可见的，没有任何滚动。如果我点击一行并导航到下一个viewController，当我返回到我的tableView时，它的

indExpathForVisibleRows

是错误的

以下是我设置的测试代码：

- (void)viewWillAppear:(BOOL)animated
{
    ...
    NSLog(@"will appear: %@", self.tableView.indexPathsForVisibleRows);
}

- (void)viewDidAppear:(BOOL)animated
{
    ...
    NSLog(@"did appear: %@", self.tableView.indexPathsForVisibleRows);
}

当我第一次使用tableView进入viewController时，我得到以下结果：

will appear: (null)
did appear: (
    "<NSIndexPath: 0xc000000000000016> {length = 2, path = 0 - 0}",
    "<NSIndexPath: 0xc000000000200016> {length = 2, path = 0 - 1}",
    "<NSIndexPath: 0xc000000000400016> {length = 2, path = 0 - 2}",
    "<NSIndexPath: 0xc000000000600016> {length = 2, path = 0 - 3}",
    "<NSIndexPath: 0xc000000000800016> {length = 2, path = 0 - 4}"
)

will appear: (
    "<NSIndexPath: 0xc000000000000016> {length = 2, path = 0 - 0}",
    "<NSIndexPath: 0xc000000000200016> {length = 2, path = 0 - 1}",
    "<NSIndexPath: 0xc000000000400016> {length = 2, path = 0 - 2}",
    "<NSIndexPath: 0xc000000000600016> {length = 2, path = 0 - 3}",
    "<NSIndexPath: 0xc000000000800016> {length = 2, path = 0 - 4}",
    "<NSIndexPath: 0xc000000000a00016> {length = 2, path = 0 - 5}"  <----THIS IS MY PROBLEM
)
did appear: (
    "<NSIndexPath: 0xc000000000000016> {length = 2, path = 0 - 0}",
    "<NSIndexPath: 0xc000000000200016> {length = 2, path = 0 - 1}",
    "<NSIndexPath: 0xc000000000400016> {length = 2, path = 0 - 2}",
    "<NSIndexPath: 0xc000000000600016> {length = 2, path = 0 - 3}",
    "<NSIndexPath: 0xc000000000800016> {length = 2, path = 0 - 4}"
)

将显示：（空）
确实出现了：(
“{length=2，path=0-0}”，
“{length=2，path=0-1}”，
“{length=2，path=0-2}”，
“{length=2，path=0-3}”，
{length=2，path=0-4}
)

点击一行，然后返回带有tableView的viewController后，我得到以下结果：

will appear: (null)
did appear: (
    "<NSIndexPath: 0xc000000000000016> {length = 2, path = 0 - 0}",

    "<NSIndexPath: 0xc000000000400016> {length = 2, path = 0 - 2}",
    "<NSIndexPath: 0xc000000000600016> {length = 2, path = 0 - 3}",
    "<NSIndexPath: 0xc000000000800016> {length = 2, path = 0 - 4}"
)

will appear: (
    "<NSIndexPath: 0xc000000000000016> {length = 2, path = 0 - 0}",

    "<NSIndexPath: 0xc000000000400016> {length = 2, path = 0 - 2}",
    "<NSIndexPath: 0xc000000000600016> {length = 2, path = 0 - 3}",
    "<NSIndexPath: 0xc000000000800016> {length = 2, path = 0 - 4}",
    "<NSIndexPath: 0xc000000000a00016> {length = 2, path = 0 - 5}"  <----THIS IS MY PROBLEM

    "<NSIndexPath: 0xc000000000800016> {length = 2, path = 0 - 4}"

将出现：(

“{length=2，path=0-2}”，
“{length=2，path=0-3}”，
“{length=2，path=0-4}”，
{length=2，path=0-5}方法
indexPathsForVisibleRows
返回表视图认为可见的单元格数。即使只有一行像素可见。此外，它可能会被剪裁，但如果它在内容区域内，表视图将对其进行计数。更重要的问题是，除了智力好奇之外，为什么要在意？方法
