iPhone - UIScrollView inside UIView not scrolling

问题

I have a UIView which contains lot of labels, buttons, textviews. But there is a certain part of that UIView that I want to make scrollable.Here is how the structure of my nib is.

-UIVIew
-UIImageView - backgroundImage
-UILabels
-UIButtons
-UIScrollView
-UITextViews

Are touch events getting assigned to somewhere else? Here is a code of my scrollview which I have written in viewDidLoad. I only want the textview inside UIScrollview to be scrollable

scrollView.delegate = self;    
[scrollView setCanCancelContentTouches:NO];
scrollView.indicatorStyle = UIScrollViewIndicatorStyleWhite;
scrollView.clipsToBounds = YES;
scrollView.scrollEnabled = YES;
scrollView.pagingEnabled = YES;
scrollView.autoresizesSubviews=YES;
[scrollView setContentMode:UIViewContentModeScaleAspectFit];
[scrollView addSubview:textview]; 

Am I mising something? is my approach right?

Thanks and regards

回答1:

scroll.contentSize= CGSizeMake(320,2700);// You can use contentsize according to your requirements

You have put here only scrollview code. So,I can't figure out what is wrong. Use following reference...

UIScrollView With UITextField

Hope, this will help you..

回答2:

[scrollView setContentSize:theSizeYouWantToScroll]

回答3:

You better should let the compiler figure out the height, instead of setting it yourself.

CGFloat height = 0;
for (UIView *v in _scrollView.subviews) {
    height += v.frame.size.height;
}

_scrollView.contentSize = CGSizeMake(self.view.frame.size.width, height);
