If you are developing applications without using <code>xib</code> <code>LoadView()</code> method is called and if there is an xib then <code>ViewDidLoad</code> method is called

So it is better to use LoadView method.

<code>ViewDidLoad</code> is called when your view loading is finished and <code>loadView</code> is called when loading starts.

And when you make a new project you see comments on these methods which clearly gives a tip when you should use which function

see this

<pre><code>/*
// Implement loadView to create a view hierarchy programmatically, without using a nib.
- (void)loadView {
}
*/


/*
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
 [super viewDidLoad];
}
*/
</code></pre>

These comments are clear and easy to understand.

blocks|key|664805|text|如果您打算使用IB来构建您的UI，那么您应该在viewDidLoad中完成所有后IB初始化。如果使用nib初始化控制器，该类将根本不调用loadView。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|664806|如果您用代码初始化控制器，viewController将首先调用loadView，然后调用viewDidLoad。根据您的首选项，可以使用loadView或viewDidLoad完成所有初始化。|664807|但是，如果您决定使用loadView，请确保在尝试读取self.view之前设置self.view属性，否则将进入无限循环并崩溃。|664808|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

If you intend to use IB to build your UI, you should do all your post IB initialization in viewDidLoad. The class will not call loadView at all if you use a nib to initialize a controller.

If you initialize the controller in code, the viewController will call loadView first, then viewDidLoad. You can do all your initialization in loadView, or viewDidLoad, depending on your preferences.

However, if you decide to use loadView, be sure to set the view property before attempting to read self.view, otherwise you will enter into an infinite loop and crash.

blocks|key|686720|text|如果您从闪存板或xib文件初始化视图，请不要覆盖此方法或调用内部的超级loadView。如果在方法中调用超级loadView，则最好不要重写此方法，并将以下代码放入viewDidLoad方法。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|686721|如果以编程方式初始化视图，则不应调用超级loadView。您必须将rootView分配给self.view属性，否则可能会出现完美的崩溃。|686722|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

If you initialize your view from stroyboard or xib file, don't override this method or call [super loadView] inside.
if you call [super loadView] inside the method, you better never override this method and put the following code to your viewDidLoad method.

if you initialize your view programmatically, you should NEVER call [super loadView]. and You must assign your rootView to self.view property, or you may get a perfect crash.

blocks|key|664738|text|这不是很明显吗？|type|unstyled|depth|inlineStyleRanges|entityRanges|data|664739|viewDidLoad叫做..。当视图完成加载时。|offset|length|style|CODE|664740|当视图被告知加载时，将调用loadView。|664741|无论是好是坏。这都取决于你的设计。|664742|祝你好运:)|664743|entityMap^0|0|0|B|0|D|8|0|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Q|8|@$D|R|E|S|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|T|8|@$D|U|E|V|F|G]]|9|@]|A|$]]|$1|J|3|K|5|6|7|W|8|@]|9|@]|A|$]]|$1|L|3|M|5|6|7|X|8|@]|9|@]|A|$]]|$1|N|3|-4|5|6|7|Y|8|@]|9|@]|A|$]]]|O|$]]

Isn't it obvious? 

<code>viewDidLoad</code> is called... When the view finishes loading. 

<code>loadView</code> is called when the view is told to load. 

Neither is better or worse. It's all dependent on your design.

Good luck :)

blocks|key|2805371|text|如果没有关联的nib，视图控制器将从与其关联的nib加载其视图，然后自动调用它的loadView()方法来填充它的视图。在这种情况下，您需要实现loadView()方法。默认情况下，它返回零。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2805372|当您的视图加载到内存viewDidLoad()方法时，您可以根据需要进行自定义初始化。|2805373|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

view controller loads its view from nib associated with it if there is no nib associated, then it automatically called it's loadView() method to fill it's View.
In that case you need to implement loadView() method.
by default it returns nil 

when your view loads in to the memory viewDidLoad() method is called here you can do your custom initialization according to your requirement.

What is the difference between viewDidLoad() and LoadView()? In what way are they different from each other?

Which one is better when we develop applications without using XIB ? 

Thanks .
