我们如何在ARC中显式调用垃圾收集器?(How can we explicitly call garbage collector in ARC? Also is there a way we can decide when to release memory in ARC?)

我是一名iPhone开发人员。 我在我的应用程序中使用ARC。 我正在分配对象,一旦它的使用结束,我将“无”分配给它。 还有什么我需要做的,以释放内存?

还有一种方法,我们可以在ARC中显式调用垃圾回收器? 还有,我们可以决定何时在ARC中释放内存?


I am an iPhone Developer. I am using ARC in my application. I am allocating objects and once its use is over I assign "nil" to it. Is there anything else I need to do in order to get the memory released?

Also is there a way, we can explicitly call garbage collector in ARC? Also is there a way we can decide when to release memory in ARC?

使用remove()函数时,元素确实从DOM树中remove()

查看页面源将显示服务器上的原始内容,并且不考虑客户端对DOM的修改。


The element is indeed removed from the DOM tree when you use the remove() function.

Viewing the source of page shows you the original content on the server, and does not take into consideration client-side modifications to the DOM.
