UIScrollview Autolayout Issue


The following code snippet in the containing view controller also seems to solve the problem, without relying on explicit sizes:

- (void)viewDidDisappear:(BOOL)animated {  [super viewDidDisappear:animated];  self.mainScrollView.contentOffset = CGPointZero;}

It does reset the content offset to the origin, but it seems that so do the other answers.


if you are still searching for an answer i found it today after two days of headbanging the wall. I will just paste you the code, but the most important thing is when you load your scrollView..

    -(void)viewWillAppear:(BOOL)animated{    [scrollView setFrame:CGRectMake(0, 0, 320, 800)];}-(void)viewDidAppear:(BOOL)animated{    [scrollView setScrollEnabled:YES];    [scrollView setContentSize:CGSizeMake(320, 800)];}

all this is loaded before -(void)viewDidLoad

notice the height is in both instances 800, which is crucial for resolving this problem. good luck with your project ;)


I was using adam's solution, but started to have problems when i was dismissing with animated:YES. In my code, content offset gets set a while after viewWillAppear (as viewWillAppear appears to be too soon).

- (void)viewDidDisappear:(BOOL)animated{    self.scrollOffsetToPersist = self.scrollView.contentOffset;    self.scrollView.contentOffset = CGPointZero;    [super viewDidDisappear:animated];}- (void)viewWillAppear:(BOOL)animated{    [super viewWillAppear:animated];    [[NSOperationQueue mainQueue] addOperationWithBlock:^     {         self.scrollView.contentOffset = self.scrollOffsetToPersist;     }];}

EDIT: another, better way is to reset it back in viewDidLayoutSubviews :)

- (void)viewDidLayoutSubviews{    [super viewDidLayoutSubviews];    if(!CGPointEqualToPoint(CGPointZero, self.scrollOffsetToPersist))    {        self.scrollView.contentOffset = self.scrollOffsetToPersist;        self.scrollOffsetToPersist = CGPointZero;    }}
