question related to NSUserDefault class
<p>I have problem in setting the object of NSUserDefault Class.</p>

<p>in a.m file i 'm setting the value of subject_textfield.
in b.m file i'm getting this value
this two operations are done by NSUserDefault class</p>

<p>now i'm setting that value for object of NSUSerDefault.
NSUserDefaults* defs7 = [NSUserDefaults standardUserDefaults];
[defs7 setObject:string4 forKey:@"subject_textfield"];</p>

<p>here string4 gives the value of subject and subject_textfield is nothing but object of UITextField in a.m file</p>
