i have a tableview with different kind of cells, one of which has some UITextFields's and UIButton. When i try to scroll this view with the touch starting in any of those subviews the table won't scroll and recognizes it as a 'touch inside' of a subview. I had it before with "delays content touches' but the touch inside button doesn't work well. Any ideas how i might fix this problem?
I just found i had an 'UITapGestureRecognizer' that was creating the problem. thank you for the help
Turning off "Cancellable Content Touches" in the UITableView solved this for me (in the UITableView attributes inspector under Scroll View / Touch). I got this from this SO question: Scrolling a UITableView inside a UIScrollView
From the UIScrollView:canCancelContentTouches doc:
If the value of this property is NO, the scroll view does not scroll regardless of finger movement once the content view starts tracking.

In my application I want add a tableview inside a UIScrollView .When the scroll of UITableView reaches the bounce, it should scroll the outer scrollview. But its not happening for me, UITableView is scrolling smoothly.Once it reaches the bounds, it stops. I need the functionality similar to the attached gif .
Please provide some code & you UIScrollView must be smaller than the view.
I am trying to create the same type of slide-up/pull-up menu (from the bottom) as the Any.do iPhone app, but not having any success.
The issue I am running into is the app was built with storyboards so I am thinking I might have to scratch that idea and use just code.
Any ideas?
There is no need to get rid of your storyboard to recreate this, that's what IBOutlets are for. Any way, it looks like this was made by creating a UIScrollView that takes up the entire screen. Then add a UITableView to the upper section of the scroll view. Mind you in order for this to work, you'll need to disable scrolling on the scroll view in the background.
From there you can programmatically add the other elements to the scroll view to be rendered off screen, since there are only three they can probably just be buttons. And finally, since scrolling is disabled on the background scroll view you can add an image with a UISwipeGestureRecognizer at the bottom of the screen to manually change the scroll view's content offset property.
My view consists of a toolbar at the top and bottom of the view and an imageView in between.
I am adding subviews to my image view.
When a subview is added, the whole view sometimes becomes distorted. The imageView will stretch, a toolbar and the bar button items shift as well.
What causes this? Has anyone came across this before?
Suggestions to fixing this matter?
Note: I have set up this view in Interface Builder, not programmatically.
Thank you!
I am trying to imbed a scrollView in the detail side of a splitViewController. Should the scrollView be added inside the 'View', as displayed in the image below?
Or does the 'View' need to be removed, leaving a View Controller and a Scroll View only?
Also, when I add the scrollView to the page, the bottom is being cut off, preventing it from scrolling all the way to the bottom. I also tried resizing the scrollView in the ViewDidLoad method of the View Controller to something extremely large such as:
theScrollView.contentSize = CGSizeMake(20000, 20000);
That did not work either. It seems that we can hold down the mouse and pan, but the scroll bars are always the same length. Thanks your help!
I have ALWAYS implemented scrollviews as the UIScrollView with a UIView inside of it, then your other elements (i.e. buttons, text views, etc...) SO the hierarchy would be
UIScrollView
UIView
UILabel
UIButton
.
.
.
Because you dont really have a top UIView WITHIN the scrollview, this is most likely why your
theScrollView.contentSize = CGSizeMake(20000, 20000);
line is not working as intended.
First off, how do you test scrolling in the iPad simulator? I have a touch pad and I've tried dragging two fingers and I've tried click & dragging two fingers, but I can't get it to scroll. Am I doing that part correctly?
Assuming that I'm testing properly, why won't my scrollview scroll? I have a basic view controller in my storyboard and I dragged a scrollview into it. I made an outlet from it into my code and then in my code I generate a bunch of buttons and add them to this scrollview. They get displayed properly. Am I missing something?
set scrollview content size such
[MyScrollView setContentSize:CGSizeMake(320, 500)];
this is for iPhone for example.
You can also make two fingers by press the alt key next to cmd in mac
HOLD PRESS alt + mouse move on simulator
set contentsize of the scrollview,to enable scroll.
Detailed explanation

You have to define the contentSize of scrollView which is generally bigger in frame than parentview or its frame to make it scrollable.
[viw setContentSize:CGRectMake(width,height)];
set it in viewDidLoad or where You alloc srollview.
