UIScrollView to start at bottom view - ios

Question

I am new in IOS Program.
I have UIscrollview with 2 vertical views and would like the page to load automatically on the 2nd/bottom view and to scroll upwards
here is my code for UIScrollView:
// Set up ScrollView
UIScrollView *scrollview = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
NSInteger numberOfViews = 2;
for (int i = 0; i < numberOfViews; i++) {
CGFloat y = i * self.view.frame.size.height;
UIView *pageView = [[UIView alloc] initWithFrame:CGRectMake(0, y, self.view.frame.size.width, self.view.frame.size.height)];
[scrollview addSubview:pageView];
scrollview.contentSize = CGSizeMake(self.view.frame.size.width, self.view.frame.size.height *numberOfViews);
scrollview.bounces = NO;
[self.view addSubview:scrollview];
}

Answer 1

Use this in viewDidLoad:
- (void)viewDidLoad {
[super viewDidLoad];
CGPoint contentOffset = CGPointMake(0, self.view.frame.size.height);
scrollView.contentOffset = contentOffset;
}
and in viewDidAppear:
- (void)viewDidAppear:(BOOL)animated {
[super viewWillAppear:animated];
CGPoint contentOffset = CGPointZero;
[scrollView setContentOffset:contentOffset animated:true];
}

Answer 2

I assume you are creating that scrollview in viewDidLoad - just add this code into viewDidAppear and set up proper animation duration:
[scrollView setContentOffset:CGPointMake(0, self.view.frame.size.height)];
[UIView animateWithDuration:5.0 animations:^{
[scrollView setContentOffset:CGPointZero];
}];
