UILabel too large to display Ignoring bogus layer - objective-c

Question

I want to display a whole chapter of a book with UILabel in a scrollview. But seems the content is too large to display, and gives following error:
[2835:157182] -[<_UILabelContentLayer: 0x60400023b040> display]: Ignoring bogus layer size (378.666667, 883959.333333), contentsScale 3.000000, backing store size (1136.000000, 2651878.000000)
And I searched for answers and some guys suggest I should use a CATiledLayer to solve this, but they didn't give a clear clue of how to do this, anyone could give some help?
Thanks,
- (void)viewDidLoad {
[super viewDidLoad];
/*** Init the scrollview and the label ***/
UIScrollView *scrollView= [UIScrollView new];
scrollView.translatesAutoresizingMaskIntoConstraints = NO;
[self.view addSubview:scrollView];
UILabel *scrollViewLabel = [[UILabel alloc] init];
scrollViewLabel.numberOfLines = 0;
scrollViewLabel.translatesAutoresizingMaskIntoConstraints = NO;
[scrollView addSubview:scrollViewLabel];
scrollViewLabel.text = #"";
NSArray *array = [Utils getCharptersWithName:#"mybook"];
for(NSDictionary *dic in array){
scrollViewLabel.text = [scrollViewLabel.text stringByAppendingString:[dic objectForKey:#"content"]];
}
NSLog(#"%#", scrollViewLabel.text);
/*** Auto Layout ***/
NSDictionary *views = NSDictionaryOfVariableBindings(scrollView, scrollViewLabel);
NSArray *scrollViewLabelConstraints = [NSLayoutConstraint constraintsWithVisualFormat:#"H:|[scrollViewLabel(scrollView)]" options:0 metrics:nil views:views];

[self.view addConstraints:scrollViewConstraints];
// Do any additional setup after loading the view.
