UIScrollView isn't working (can't scroll)

Question

I'm adding a UIScrollView to the reusable view I'm making and then adding that reusable view to a UIViewController.

In my reusable view I'm adding UIViews to the UIScrollView :

 int yLocation = 20;
    for (int i= 0 ; i < 5; i++) {
        UIView *tempView = [[offerCell alloc]initWithDelegate:self];
        tempView.frame = CGRectMake(5, yLocation, 290.0F, 70.0F);

        yLocation += 90;

        [self.scrollView addSubview:tempView];
        UILabel *tempLabel = [tempView viewWithTag:1000];
        tempLabel.text = [NSString stringWithFormat:@"Label Number %d" , i];
        [tempLabel sizeThatFits:CGSizeMake(1000, 1000)];
    } 
    self.scrollView.contentSize = CGSizeMake(self.scrollView.frame.size.width, yLocation);

Then I'm adding the UIView to my UIViewController

UIView *tempView = [[BuyTokensView alloc] initWithDelegate:self andViewController:self];
[self.view addSubview:tempView];
CGPoint point = CGPointMake(10, 0);
tempView.center = point;

The view is shown correctly but I can't scroll the UIScrollView. My UIScrollView height is smaller than the Height I'm assigning in ContentSize, so why can't I scroll?

Here is a picture of the UIViewController:

log scrollview height. Check whether you add scrollview as subview. — Aravind Bhuvanendran
I add the scrollview as a subview I wrote that, and the height is fine. — Eli Braginskiy
i think you should add tempview over scrollview [self.scrollView addSubView:tempView] — Aravind Bhuvanendran
@AravindBG what do you mean? I add tempView to scrollView.. [self.scrollView addSubview:tempView]; — Eli Braginskiy

Either you can try to disable autolayout or use the strategies in this technical note:
