I have a small Doubt, If i want to have a menu fixed on top how can i achieve it? Therefore you need to set an explicit height or make their height relative to other controls. A scroll view also handles zooming and panning of content. Sample code can be found here: To do this click on the view controller, select the size inspector and select Freeform size.
iOS: Maintaining Content Offset When The Size Of Your UIScrollView Changes
The first solution is to disable shadows when UIView is uiscro,lview visible by setting a “0” value for the shadowOpacity parameter. In this solution, you use a special service to perform the required operations. You take the minimum of the width and height zoom scales, and set this for both minimumZoomScale and zoomScale on the scroll view.
Does the constraint reference something from outside the subtree of the view? After that, you need to create a convention between all the platforms that includes the content of the asset and information about the basic link uisceollview with a postfix in order to display the t resolution. Thanks for the post. Here’s the link with a postfix used to get the content in a specific resolution: I need some way to expand my content view in the horizontal direction to fill the width of the device.

CGFloat A floating-point value that specifies the minimum scale factor that can be applied to the scroll view’s content. The ey will then stretch on auto rotation and no additional constraints in code are needed.
Hi Mike Woelmer, I am facing issue when the content of my view is going beyond the height of the Scroll View. In the project described within this article, the horizontal UIScrollView served as a container for tables, changing their size in accordance with the currently visible UITableView.
Hi MikeHow can i Set constrain when my scrollview contain view which has greater height than scrollview? Everything works great except for one thing. If you’re using a UIScrollView or any classes that have a scroll view as part of their layout table views and text views, for examplethis means adjusting the contentInset property to account for the keyboard.
Overridden by subclasses to customize the default behavior when a finger touches down in displayed content. Nice post, but the key: I included Swift code samples. Depending on how long the comment is, you may end up with more text than your device can display: We know that — in the words of computer scientist Donald Knuth — “premature optimization is the root of all evil,” but forewarned is forearmed.
However, when I do this part: It gives you access to an awfully large market share in the consumer handheld market after all: Note that the gesture can end and a finger could still be down.
In other words, the scrolling happens only in UIScrollViewwhich was used to detect a gesture. This only allows you to layout all of your controls on the storyboard. I am using a navigationBar with my project. It would be great if someone could clarify the difference. Suppose I have Labels which I need to put on my scroll view vertically one after another. In this case, you need to translate the textView activeTextView in my code below location to self before deciding if scrolling is needed.
And anyway, such knowledge will undoubtedly save you both precious time and nerve cells. I could hard code a width uiscroklview, but that will only work for portrait or landscape and not both.
Using UIScrollView with Auto Layout in iOS
I think I just woke up the neighbors with a loud cheer of joy! Coonvert The point at which the origin of the content view is offset from the origin of the scroll view. The scroll view calls scrollViewDidZoom each time the user scrolls. Forms with UITextFields are working. But as you can see, I have a problem in the horizontal direction.
