Caculate the size of string:

<pre><code> NSString *choiceDString = @"Equal the present value....";
 CGSize size = [choiceDString sizeWithFont:[UIFont systemFontOfSize:CHOICE_FONT_SIZE] constrainedToSize:CGSizeMake(CHOICE_WIDTH, 100000)];
</code></pre>

Init a label to content the choice string:

<pre><code> UILabel *choiceDLabel = [[UILabel alloc] initWithFrame:CGRectMake(0,0,size.width,size.height)];
 choiceDLabel.text= choiceDString;
</code></pre>

Add the subview label for button:

<pre><code> [button addSubview:choiceLabel];
</code></pre>

Use this code..Yo have define height of label according to your text length...

<pre><code>NSString *summary;
summary = @" your text";
CGSize sizeofbuttonorlable = [summary sizeWithFont:[UIFont systemFontOfSize:30] 
 constrainedToSize:CGSizeMake(self.view.bounds.size.width - 40, MAXFLOAT) 
 lineBreakMode:UILineBreakModeWordWrap];

CGRect frame = CGRectMake(0.0f, 0.0f, 320.0f, sizeofbuttonorlable.height);
UILabel *choiceDLabel = [[UILabel alloc] initWithFrame:frame];
choiceDLabel.text= summary;
[button addSubview:choiceLabel];
</code></pre>

Hope, this will help you...chill

blocks|key|5243892|text|我的建议是首先计算您在textView中输入的文本的大小，如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5243893|++++++//Give+the+maximum+size+of+label+which+that+label+can+have.

My suggestion is to first Calculate the size of the text entered by you in the textView like:-

<pre><code> //Give the maximum size of label which that label can have.
CGSize maximumLabelSize = CGSizeMake(300,500);
CGSize expectedLabelSize = [Label.text sizeWithFont:Label.font constrainedToSize:maximumLabelSize lineBreakMode:UILineBreakModeWordWrap];

 //adjust the label the new height.
CGRect newDescFrame = Label.frame;
newLabelFrame.size.height = expectedLabelSize.height;
NSLog(@"%f",newLabelFrame.size.height);
 //adjust the label the new width.
newLabelFrame.size.width = expectedLabelSize.width;
NSLog(@"%f",newLabelFrame.size.width);
 //Set the label size according to the new height and width.
label.frame = newLabelFrame;
</code></pre>

Write above mention code after entering the text in the textView.
Hope it helps.Thanks :)

I need help with this peculiar problem. I have a multiple choice question app and I have the choices as UITextview. Sometimes, choice D gets cut in half for whatever reason.

Screenshot:
<img src="https://i.stack.imgur.com/UtF23.png" alt="Choice D is halved!">

Not sure what's going on here. I basically have the UITextView frame adjust to its contentSize.

<pre><code> CGRect dFrame = choiceD.frame;
 dFrame.size.height = choiceD.contentSize.height;
 choiceD.frame = dFrame;
</code></pre>

Any ideas? Thanks in advance.

EDIT: UITextView Label is Cut in Half (Horizontally)
