推荐答案

似乎 numberOfSectionsInTableView 和 numberOfRowsInSection 是0.如果是这种情况，则不会调用cellForRowAtIndexPath ..

It seems the numberOfSectionsInTableView and numberOfRowsInSection returned are 0.If this is the case then cellForRowAtIndexPath will not get called..

从上面的注释看来，似乎YourAppDelegate变量是 null 或yourArray null 。尝试在这些代理上保留断点，检查它们返回的值

From the comment above..it seems that "YourAppDelegate" variable is null or yourArray is null.Try keeping the break point on these delegates ,to check the values returned by them
