I'm programming on objective-c. How can I create scroll with paging enabled like this.
First check the property of scroll view for Paging enabled.Then set your scroll view content size corresponding to how much page you want.
You can try this implementation
https://github.com/100grams/HGPageScrollView
There's also a nice website for custom cocoa controls http://cocoacontrols.com/, where you can find very good stuff, so you won't need to invent the wheel =)

When I try to place objects using the Interface Builder in Xcode into a NSScrollView, they appear fine until runtime in the application, where they do not appear at all for some reason. I want it to be so that I can place multiple buttons and labels in the view, and have the user be able to scroll down to see more.
Am I not meant to use NSScrollView for this purpose?
Is there another way to go about implementing it I am not aware of?
You need to check the where you added the UI objects.
You need to consider these :
Is your autolayout enabled?
Did you flipped the view?
Resizing mask is working good as per your requirement.
Am I not meant to use NSScrollView for this purpose?
No, you picked the correct control for the requirement. NSScrollView is indeed for same kind of use.
I am displaying hundreds of thumbnails in my view . I know default way to handle tap on thumbnail is using UICollectionView delegate method "didSelectItemAtIndexPath" but since its many thumbnails i wanted to look into adding gestures to the screen position so when i tap on a particular spot on the screen, it will handle the event accordingly for that particular thumbnail underneath. I would like to know if it is a good/possible approach?
It would be a hell of a lot easier to use a UICollectionView.
If you need a custom layout then you can subclass UICollectionViewLayout and get some really cool dynamic layouts.
You also get the added bonus of dequeued cells meaning that you get better memory management using it.
You may find UIGestureRecognizer useful. A good tutorial to get you started is here.
The question may be similar with
Designing inside a scrollview in xcode 4.2 with storyboards
but none of the answer there makes sense at all.
Okay I created a new controller and I added a scrollView.
The very first thing I noticed is there is NOWHERE to specify the content size of the scrollView.
Not in attributes inspector, not in size inspector.
Then what?
I am expecting some larger than normal box where I can draw all the view I want to put in. There is no such thing either.
I am very frustated.
All the "tutorial" out there tell about how to fill scrollView using code.
Another thing I tried is to select controller go to size inspector and then choose FREEFORM.
Great. I still can't make that template big.
Should I do this in XIB instead? At least on that one I can have one huge UIView. Or what is the official way industry standard way of doing this? Is there a WWDC for this one?
Say I want to draw something like these:
I don't think you can get a tutorial on this as it is simply impossible in IB. As most people already commented out what you want to do here need to be done programmatically.
If you are using XIB you can set up all your content there. Under the size tab (in the inspector) you will need to change the height to fill all your content but you still need to set up your contentSize programmatically.
For storyboard I don't think it is possible to change the size of your scrollview in IB.
I know there are plenty of Grid Views out there for iOS and Objective-c, but I couldn't find one that fits me. Currently I use a grid view called UIGridView. It included only two files and was very simple to implement. However it cannot have more cells than it can fit on the screen. I want a dynamic grid view where I can have a UIPageControl to have multiple pages with cells. I like the UITableView but for this project it would be more efficient to have a grid view.
I currently use this grid view: http://www.chupamobile.com/products/details/380/Interactive+Grid+View/
Is there a simple grid view with page control? Or can I put my current grid view in in a UIPageControl?
Did you try CHGridView at https://github.com/camh/CHGridView ?
I settled with the MMGridView. It has horizontal page control scrolling. I just modified the cells to my liking. You can find the git source here: https://github.com/provideal/MMGridView
I am currently using AQGridView so surely i recommend that as it is the least buggy and its functions are very similar to UITableView.
Also that If you are trying to do this without XIB it will be little bit difficult for you to handle it but you can create a view controller with Xib file to Create the interface of your choice. Here is the Video of how it can be done in the best possible way by Evadne Wu. And here is the Sample Project
Now for the Paging Control
in AQGridView you just need to set Paging Enabled and it will automatically do the rest. Hope that helps.
I would like to programmatically Add a UIScrollView in a UIAlertView.
I found a way to do that but I was not successful in adding text to this UIScrollView (using the same code as in here: https://www.youtube.com/watch?v=4SG0CAAl5u0).
is there an alternative to do that? the text I have is very long and I need people to be able to scroll but without being able to edit it.
I know that the Apple user interface guideline does not recommend long text in alerts (although detecting WiFi networks does that) but I have no choice but doing it
If you add a large text in UIAlertView it automatically becomes scrollable.
You don't have to do any thing to make it scrollable.
Here is a control on github that has a tabelView inside it. If you need to customize beyond what Inder suggests, you might want to look at the code and replace the tableView with a scrollView.
Also, there are other controls at cocoacontrols.com that might help you directly or give you some ideas.
