从调试的角度讲,NSPointerArray没有受到太多欢迎。description方法只是简单的返回了<NSConcretePointerArray: 0x17015ac50>。为了得到所有的对象需要执行[pointerArray allObjects],当然,如果存在NULL的话会改变索引。 NSPointerArray性能特征 在性能方面,NSPointerArray真的非常非常慢,所以当你打算在一个很大的数据集合上使...

The pointer created through implicit bridging of an instance or of an array’s elements is only valid during the execution of the called function. Escaping the pointer to use after the execution of the function is undefined behavior. In particular, do not use implicit bridging when cal...
