iOS UITableView cellForRowAtIndexPath未调用

是UITableView numberOfRowsInSection未呼叫。但是没有调用CellForRowatineXpath。我不明白为什么不调用CellForRowatineXpath。如果我重新运行节中的行数

 return (allOfficedata.count >0)? allOfficedata.count + 1 : allOfficedata.count; 

 Feedmodel *fmodel=[allOfficedata objectAtIndex:indexPath.row];

或

 Feedmodel *fmodel=[allOfficedata objectAtIndex:indexPath.row];

如果我给出返回数组计数，则不调用cellforrowatindexpath；或返回11；工作正常，我附上了我的代码，错误

 Feedmodel *fmodel=[allOfficedata objectAtIndex:indexPath.row];

*****由于未捕获的异常“NSRangeException”而终止应用程序，原因：“*-[\uu NSArrayM objectAtIndex:]：索引10超出边界[0..9]”

 Feedmodel *fmodel=[allOfficedata objectAtIndex:indexPath.row];

---

因此，您说allOfficedata+1表示部分中的行数，但高度表示行数：您有以下行：

 Feedmodel *fmodel=[allOfficedata objectAtIndex:indexPath.row];

 Feedmodel *fmodel=[allOfficedata objectAtIndex:indexPath.row];

这会导致最后一个单元格崩溃，因此您需要检查它是否是最后一个单元格，以及它是否正在执行其他操作

 Feedmodel *fmodel=[allOfficedata objectAtIndex:indexPath.row];

编辑：

 Feedmodel *fmodel=[allOfficedata objectAtIndex:indexPath.row];

而且你似乎在CellForIndexath中也做了类似的事情

 Feedmodel *fmodel=[allOfficedata objectAtIndex:indexPath.row];

如果（indexPath==0），您将执行某些操作，但在这之后，对于下一个单元格，您将获得：

 Feedmodel *fmodel=[allOfficedata objectAtIndex:indexPath.row];

您应该从indexPath.row中得到-1，因为当前您对位于的单元格的get，比如indexPath.row==1，您在索引1处请求对象，我认为您应该请求0。当你到达最后一个单元格时，应用程序将在上面的一行崩溃

 Feedmodel *fmodel=[allOfficedata objectAtIndex:indexPath.row];

编辑2：

 Feedmodel *fmodel=[allOfficedata objectAtIndex:indexPath.row];

因此，问题是您向allOfficedata请求一个不存在的索引，当您对行说allOfficedata+1时，当它到达表中最后一个单元格的高度ForRowAtIndexPath时，它向allOfficedata请求不存在的索引的数据，因为它正在查找您在numberOfRowsInSection中给出的+1

 Feedmodel *fmodel=[allOfficedata objectAtIndex:indexPath.row];

假设allOfficedata的计数是10（索引0-9），我们已经说过表中的行数是allOfficedata+1，所以它是11（索引0-10）

 Feedmodel *fmodel=[allOfficedata objectAtIndex:indexPath.row];

---

现在在HeightForRowatineXpath中，我们看到最后一个单元格（索引10），allOfficedata没有它，因为它的索引是0-9。如果向allOfficedata请求索引10，它将崩溃

NSArray

出界了

 Feedmodel *fmodel=[allOfficedata objectAtIndex:indexPath.row];

• 数组0到9中的10个值[非1到10]
• 表中的索引也是 相同的0到9[不是1到10]

---

因此，

indexpath.row

将为您提供正确的值，用于从位于正确位置的数组中确定值

除了行计数错误之外，cellForRowAtIndexPath从未被调用的最可能原因是表视图认为没有要显示的行

 Feedmodel *fmodel=[allOfficedata objectAtIndex:indexPath.row];

cellForRowAtIndexPath仅在需要单元格时调用。您的代码中似乎有高度非常大的单元格。无法看到节标题视图或高度的任何代码

 Feedmodel *fmodel=[allOfficedata objectAtIndex:indexPath.row];

因此，考虑到很大的高度，特别是对于第0行（根据您的代码为300或400），除非您向上滚动，否则不会有太多对该函数的调用。滚动时，您应该会看到更多对单元格的调用

 Feedmodel *fmodel=[allOfficedata objectAtIndex:indexPath.row];

还要检查高度是否返回0，因为这也会阻止它尝试显示单元格，我认为它不会被看到

 Feedmodel *fmodel=[allOfficedata objectAtIndex:indexPath.row];

---

它将要求每行的高度来估计所需的滚动条大小。

检查

numberofrowsinssection

返回的值。我正在返回return[allOfficedata count]+1；同样的问题我不知道

[allOfficedata count]+1的值是多少，我怎么知道？你能解释一下你想做什么吗？allOfficedata是一个数组，检查：[Array count]+1；或数组。计数+1；它不是调用CellForRowatineXpath。我已经尝试了更多的例子。它不会到达cellAtIndexPath，因为在那之前它会在Rowatindexpath的高度坠毁。我检查了这个东西。当我在那里返回值时，它的获取错误。如果我手动返回11表示其工作，如果我这样返回表示返回NSArray.count+1；意思是显示错误。安德问题解决-切扬帮我
 Feedmodel *fmodel=[allOfficedata objectAtIndex:indexPath.row];
