tableview加载时,在cellForRowAtIndexPath里会报错,这是因为里面确实返回了nil的cell,一定要相信程序给你的反馈
self.dataArray = [NSMutableArray arrayWithArray:award_array];
[self.dataArray insertObject:[NSNull null] atIndex:];
if (self.recommendAppDic)
[self.dataArray insertObject:self.recommendAppDic atIndex:];
self.dataArray = [NSMutableArray arrayWithArray:award_array];
if (self.recommendAppDic)
[self.dataArray insertObject:self.recommendAppDic atIndex:];
[self.dataArray insertObject:[NSNull null] atIndex:];
看看上面两块代码有什么区别.
