I have a scrollView and inside it some scrollViews , and everyone have a webview to show html file, using this method I will zooming every html file , but Now I found that when I scroll the html file it didn't work. I think I scroll the scrollview inside and it autosize the html file , but How to let the scrollview inside not to call the scroll function and when I scroll the html it can call the scroll function outside, and I have disable the scroll property of inside scrollview, but it didn't work, and How to do with it? Thank you very much!
UIScrollView in UIScrollView is a common use. See apple stocks app...
I am trying to send ScrollView Gesture events like pan and zoom from outside the scrollview itself. It doesn't look like apple lets you send to the UIScrollViews handlePan: and handleZoom: methods
A quote from UIScrollView Class reference :-
Important: You should not embed
UIWebView or UITableView objects in
UIScrollView objects. If you do so,
unexpected behavior can result because
touch events for the two objects can
be mixed up and wrongly handled
I would add : "You should not embed UIScrollView objects in UIScrollView "

I am trying to add a UILabel along with a UIWebView together in a view controller and want them to scroll together. So to accomplish that, i have added a UIScrollView behind these two views but the UIScrollView is just not scrolling. I am using Storyboard and iOS 7 SDK.
I have seen many questions but they are not of much help. Some are suggesting that i should disable the AutoLayout that i cannot do due to the requirements of my project. What else can i do to make it work? Thanks!
According to Apple's documentation, you shouldn't use UIWebView inside UIScrollView. What you can do is to add your UILabels and UIWebView inside aother UIView and then add this UIview inside the UIScrollView.
Secondly, you have to set the contentSize of the UIScrollView in order for it to work.
You also have to disable the scrolling of UIWebView that is embeded inside the UIScrollView.
Still if your problem is not solved. It is better to just turn of AutoLayout. I have had the same issue and i wasnt able to solve it without disable the AutoLayout.
The documentation for UIWebView states:
Important: You should not embed UIWebView or UITableView objects in
UIScrollView objects. If you do so, unexpected behavior can result
because touch events for the two objects can be mixed up and wrongly
handled.
You need to wrap the label and web view in a regular UIView. Add the regular view to the scroll view.
I have added a UIWebView along with some labels inside UIScrollView (using StoryBoards) by adding it as a subview and then setting the ScrollView height to show all the html content of WebView that is loaded in it using loadHtmlString.
The links in the html content are not working. A little searching revealed that Apple does not recommend putting UIWebView inside UIScrollView to avoid unexpected behaviour. But as i also have to add labels and other stuff other than the UIWebView, so i have to embed them inside UIScrollView.
Is there any way I can make the links work in the html content without violating and Apple's recommendation?
There is no reason to put a UIWebView inside a ScrollView. UIWebView will scroll and zoom and pan the content properly as is. It is sort of redundant unless you have some other layout reasons for example combining it with some other views.
The correct way to add your labels is to add them to a UIViewController or NavigationController and have them positioned around the UIWebView and to also add the UIWebView to that as well.
i've got a tableview. inside this, i have a tableviewcell with a horizontal scrollview inside it.
it works fine, but if i start scrolling horizontal inside a tableviewcell and move a bit up or down, the horizontal scrolling stops and the tableview gets scrolled.
is there a way to prevent the tableview from scrolling while scrolling horizontal inside a tableviewcell?
thanks for all help
try scrollView.canCancelContentTouches = NO
If that doesn't work you may have to do more complicated handling of touch events by subclassing UIScrollView. (Look at touchesBegan:event:, touchesMoved:event:, touchesEnded:event:, touchesCancelled:event:)
you should not put the UIScrollView inside an UITableView. you could show the content of your cell vertically Or show on the details view
UITableView is a subclass of UIScrollView.
Form Apple Documentation.

I need following view structure, with embedded 2 UIWebViews and 1 UIView (loaded from other xib).
But the problem is, because this need to be inside UIScrollView, with same impression like this is single page. (only vertical scrolling need to be enabled).
In those UIWebViews, html content is loaded from NSString.
Size (height) of UIWebViews and child view is variable.
Any advice, how to do that?

However why cant you make a webview that has two iframes, with the content of your two html-files? Then attach this webview to the uiview?

I'm displaying a UISearchBar at the top of a UIWebView for entering information that I use to display content in the UIWebView. Is there a way to attach the UISearchBar (or perhaps a UITextField?) to the UIWebView "header" so that when the user scrolls down on the webview the UISearchBar also scrolls out of view and the full window is able to display text?
If this is not possible, how else could I accomplish this while still using the UIWebView for it's inherent text formatting capabilities?
You may try containing the UIWebView and UISearchBar within a UIScrollView. That is, create a controller that has the main view as a UIScrollView and then add in the UISearchBar and UIWebView as subviews. If you want custom behavior when you're scrolling you may have to override the event callbacks for scrolling. I haven't tried this but in theory you could have it so that when you get a scroll down and the UISearchBar is in view, you hide it up to a certain # of pixels until the UISearchBar is hidden. Afterwards you forward the scroll request to the UIWebView so it can deal with things. Basically have a middleman that delegates the scroll events as necessary.
