Add scrollview iOS Objective-C

Question

I have the following code in viewDidLoad on my ViewController:

self.navigationController.navigationBar.tintColor = [UIColor colorWithRed:204.0/255 green:00.0/255 blue:00.0/255 alpha:1];
self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"background.png"]]; 

autoNameLabel.text = (NSString *)[vendorDetails objectForKey:@"autoname"];
homeLabel.text = (NSString *)[vendorDetails objectForKey:@"homelab"];
descriptionTextView.text = (NSString *)[vendorDetails objectForKey:@"description"];

This all fits perfectly on the view. I know need to add an additional textView on the bottom so need the user to be able to scroll to see it. How can I add this info to a scrollable view and add my additional textView?

Answer 1

you could have your UIViewController extend UISCrollViewController. Or you could add a UIScrollView to your view controller's view in the method viewDidLoad . Then add all subviews of your view to the scrollview instead.

self.scrollView = [[UIScrollView all] initWithFrame:self.view.bounds]
self.scrollView.contentSize = CGSizeMake(self.scrollView.bounds.width, HEIGHT_OF_SCROLLABLE_AREA).

I would also do something like this for the scroll view height if your last textview is named lastTextView

HEIGHT_OF_SCROLLABLE_AREA = CGRectGetMaxY(lastTextView.frame + bottomPadding)

Answer 2

Are you sure you dragged all the other views on the scrollview? Make sure the contentSize of the scrollview is high enough(you know, higher than the screen) to scroll.

Answer 3

have u set delegate of UIScrollView. if you have not set delegate of UIScrollView then also it may possible that your scroll is not working.
