#存储

本文介绍了一种通过指针操作来直接修改容器中元素的方法。使用这种方法时, 对指针所指向的对象进行的任何更改都会反映到容器中的相应元素上。

dict = [ _mutableArray objectAtIndex:indexPath.row ];

 

返回 的存储在容器中的指针，修改dict会影响到容器中的数值。

一句平常得不能再平常得代码NSArray *array = @[@1,@2,@3]; NSNumber *num = [array objectAtIndex:3];很容易看出，要取出的值已经超过了数组最大长度，出现数组越界的情况。在平常开发中，这种错误还是比较容易定位，但是crash机制还是比较让人头痛，而且如果在项目中多处使用到这个，发生崩溃后也难以一下子找出发生崩溃的数组。所以自然想改造一下...

NSArray、NSMutableArray、NSDictionary、NSMutableDictionary、是我们的在iOS开发中非常常用的类。当然，在享受这些类的便利的同时，它们也给我们带来一些困扰。粗心我们可能会调用addObject:传入一个nil, 也有可能是会objectAtIndex:传入一个越界的index。尤其是在数据基本依赖于服务端返回的的情况，这种crash大幅增加。最近项...
iOS reason: '*** -[__NSArrayM objectAtIndex:]: index 0 beyond bounds for empty array'

原因： 意思是你在使用数组的时候，比如你有0-8 共9个对象，可你要去取第10个元素array[9]（[array objectAtIndex:9] ）那肯定出错了，可以看看是哪个地方的数组下标用错了。

错误原因： 数组中有5个元素，列表有5个数据，在删除列表数据并刷新列表后，数组取值的时候没有进行判断。 解决方法： 在取值的时候，需要判断数组元素大于列表数据或者列表数据小于数组元素  if(self.dataSources.count&gt;indexPath.row)或者 if(indexPath.row&lt;self.dataSources.count)...
