One of the most significant advantages of Java is its memory management. You simply create objects and Java Garbage Collector takes care of allocating and freeing memory. However, the situation is not as simple as that, because memory leaks frequentl…

什么是内存泄露 内存管理一直是Java 所鼓吹的强大优点.开发者只需要简单地创建对象,而Java的垃圾收集器将会自动管理内存空间的分配和释放. 但在很多情况下,事情并不那么简单,在 Java程序中总是会频繁地发生内存泄露(Memory Leaks).   内存泄露的定义: 当某些对象不再被应用程序所使用,但是由于仍然被引用而导致垃圾收集器不能释放他们. 用白话来说就是: 该回收的内存没被回收,最后因为内存不够用而导致程序报错.   要理解这个定义,我们需要理解内存中的对象状态. 下图展示了什么是…

Android applications are, at least on the T-Mobile G1, limited to 16 MB of heap. It's both a lot of memory for a phone and yet very little for what some developers want to achieve. Even if you do not plan on using all of this memory, you should use a…

教程截图: 作为一名无证程序员,无论你多么精通Objective-C的内存管理,随着时间的推移,你也不可避免的犯内存相关的错误.但通常因为代码量太大,以至于你不可能一行一行的去排除(等你解决完,你设计的动车早相撞了!) 幸运的是,苹果已经提供了一些好的方式来帮助你找到应用程序中内存相关的问题.有时,这些工具可能吓到初学者,但它们实际上相当有用并易于掌握! 这就是本教程说要介绍的.你会亲手使用内存工具在XCode环境下很轻松的检测内存问题. 这篇教程是建立在你非常熟悉Objective-C内存管理…
在ARC(自动引用技术)前,Objective-c都是手动来分配释放 释放 计数内存,其过程非常复杂. ARC技术推出后,貌似世界和平了很多,但是其实ARC并不等同于Java或者C#中的垃圾回收,ARC计数只是在XCode在编译的时候自动帮我们加上了释放 计数+1 计数-1. 内存泄露例子: 然而在一些特殊的情况下,内存泄露依然存在,而且防不慎防,这里讲一下Objective-C中Block计数是如何产生内存泄露的,如下代码 .h中 typedef void (^CompletionBlock)…
