After setting a webview as a property, do we have to init it before using it ?

I can see Amit set webview as a property in h file, then in m file when he used it in viewdidload method, he use it directly as "self.webview" without initializing it , and it just worked!

I am very confused. Should the teacher write something like 

self.webview=[[UIWebView alloc] init];

before using it ?

Hi Jack,

You only ever need to initialize classes if you're creating them programmatically, if you add the view using the storyboard editor Xcode will automatically add the constructor code in when it's compiling your code.

thanks chris! i have considered this possibility, but if this is the case, Atim should have sent this webview to WEAK because this controller doesn't own it ,instead, the view owns it. Am I right?
