如何增加UIScroll视图的滚动区域

Question

I have a scroll view with 5 images and some text views. It scrolls horizontally.

Now, when I scroll the content of the scroll view moves to an area.
How can I increase this limit?

I mean: I need to scroll more on single scrolling.

I have tried with increasing the contentSize .
It does not have the desired result: only the content of scroll view got increased.

Answer 1

尝试使用代码。

[scrollView setDecelerationRate:UIScrollViewDecelerationRateFast];

Answer 2

您可以在scrollview委托方法中设置scrollview的contentoffset属性

- (void)scrollViewDidScroll:(UIScrollView *)scrollView

Answer 3

You can try it on viewDidLoad method :: scr.contentSize = CGSizeMake(320, 500);
or whatever you want height.

Otherwise you can set it dynamically after all images & textviews will be loaded.

eg. float h = [imagesCount * imageHeight] + [textVwCount *textVwHeight] + 100;

then set to scr.contentSize = CGSizeMake(320, h);

But keep in mind, always put height's value greater than actual size for ScrollView control.

Hopefully it will help you.

Thanks.

Try this

use UIScrollviewdelegate in .h file

and then use

-(void)scrollViewDidEndScrollingAnimation:(UIScrollView *)scrollView
{

in that function use

[scrollview setContentOffset:CGPointMake(scrollview.frame.origin.x+(value u want to scroll more) , 0) animated:TRUE];

The above code will allow ur scrollview to scroll more
