Use with :

For Accept Button:

btnAccept!.frame = CGRectMake(CGRectGetMinX(txtView!.frame), CGRectGetMaxY(txtView!.frame) + 20, btnAccept!.frame.size.width, btnAccept!.frame.size.height)

For Decline Button:

btnDecline!.frame = CGRectMake(CGRectGetMinX(txtView!.frame), CGRectGetMaxY(txtView!.frame) + 20, btnAccept!.frame.size.width, btnAccept!.frame.size.height)

variable btnAccept is accept button

variable btnDecline is decline button

variable txtView is textview

Instead of hardcoding, use Autolayout. 

Set Accept button left edge constraint to label left edge constraint.
Set Decline button right edge constraint to label right edge constraint. 
Add vertical space between buttons and label.

Take label height constraint reference and set it's constant at runtime which is equal to label height.

CGSize maximumLabelSize = CGSizeMake(296, FLT_MAX);

CGSize expectedLabelSize = [yourString sizeWithFont:yourLabel.font constrainedToSize:maximumLabelSize lineBreakMode:yourLabel.lineBreakMode];   

//adjust the label the the new height.
CGRect newFrame = yourLabel.frame;
newFrame.size.height = expectedLabelSize.height;
yourLabel.frame = newFrame;

According to label's height set your button's frame
