您正在空
NSMutableArray上使用参数0调用objectAtIndex:。如果您知道 NSMutableArray 可以为空，则应考虑调用
count来查看它是否确实包含任何元素，在尝试访问元素之前。You're calling
objectAtIndex:with the argument0on an emptyNSMutableArray.If you know the
NSMutableArraycan be empty, you should consider callingcounton it to see if it does indeed contain any elements, before trying to access the elements.显然，
-[UMMFlickrView photoGallery:urlForPhotoSize:atIndex:]中有一个空的NSMutableArray，并且您使用参数 0 发送了objectAtIndex:。Obviously, there's an empty
NSMutableArrayin-[UMMFlickrView photoGallery:urlForPhotoSize:atIndex:]and you sent itobjectAtIndex:with argument 0.这意味着你的 NSMutableArray 是空的。我认为你没有为 NSMutableArray 分配内存。阅读此链接，它可能对您有帮助。

That means your NSMutableArray is empty. I think you didn't allocate the memory for NSMutableArray. Read this link, it may be helpful for you.

可能在第四次单击时，没有任何内容被推入数组中，我不确定，因为我不知道您要做什么。如果您可以添加将对象添加到数组中的代码行，我们可以帮助您。
发生此错误是因为数组肯定是空的。
May be on the 4th click nothing is pushed into the array, I'm not sure as I have no idea what you are trying to do.If you can add the code line that adds the object into your array, we could help you.
This error is occurring because the array is empty for sure.
