line 102 is behaving wrongly on iOS7, but seems to work correctly on iOS6. 
If the text is really long and exceeds the frame, line102 makes the UITextView unable to scroll.

To fix this, remove line 102, and thus line 104, 105 and 106 should be now be removed too. This fix has another benefit that now the creator label and the join button won't float on the UI according to different length of informedConsentForm.
