how can i set mTextView to show on button click
<p>i have a UITextView object which i have created in interface builder with it's hidden property unmarked.Now i want this textView to be invisible when my application launches and first view appears.Further i want it to be displayed when a particular method is called.Now this is what i have written in view did load</p>

<pre><code>[mTextView setHidden:YES];

self.mTextView=[[UITextView alloc] init];
</code></pre>

<p>it hides the textView ats the first view appears but when my desired method is called and i write</p>

<p>[mTextView setHidden:NO];
it does not show it again..
Is it like we cant change the appearance of a textView once it is assigned because after assigning memory as</p>

<p>self.mTextView=[[UITextView alloc] init];
and then writing</p>

<p>[mTextView setHidden:YES];</p>

<p>it does not hide textView in viwDidLoad either.....</p>
