首先看一下官方解释: - (void)loadView; // This is where subclasses should create their custom view hierarchy if they aren't using a nib. Should never be called directly. - (void)viewDidUnload NS_DEPRECATED_IOS(3_0,6_0); // Called after the view controller's vi…

- (instancetype)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil viewDidLoad viewWillAppear viewWillDisapppear <iOS编程>P137关于视图的初始化代码不能写在视图控制器的初始化(1),原因如下:为了实现视图延迟加载,在initWithNibName:bundle:中不应该访问view或view的子视图,而应该放在viewDidLo…

对于iphone开发人员来说,内存管理是极为重要的技巧,哪怕程序的功能再强大,设计再漂亮,如果内存控制不好,也难逃程序莫名退出的噩运,这与网页开发是完全不同的. 内存控制里面有很多门道,在这里分析一下 viewDidUnload 和 dealloc 的区别,关于这两者的区别的文章很多,但是大都是摘抄和翻译官方文档,有的也只是简单的说两句,并没有详细说出两者具体的区别. 在了解两者之间的区别,首先要知道 view 的生命周期,google 里面有很多文章,可以先去搜一下,这里就不详解了. 顾名思义…
