I am new to iOS and i have some serious problem i don't know why this happened, i also tried to find out the reason behind this but i failed.
I am creating a app in iPhone which take tweet of particular user using twitter api, i have no problem in getting the json data, also able to display it in UITableView in iOS 6 using storyboard, i had changed the row height to 200 px, so that i can display user name text tweet and image.
But when I scroll up or down the UITableViewCell the scrollbar goes out of the screen.
What may be the reason?how can I fix it?
ScreenShots
First it shows like this when the app loads the scrollbar takes the full screen
then when i scroll it get out of the screen
at last it completely gets out of screen
