I'm working with Xcode developing for iOS using a UIScrollView. I got the scrollview working just fine.
But my issue/question is dealing with how to use the scrollbar on the side of the scrollview:
For example, I have dynamically created 2000 buttons inside the scrollview, in the simulator. The buttons are lined up vertically, so I have to scroll down to see all of the buttons. I do not want to simulate scrolling 30 to 40 times in order to get to the 1500th button.
I have the code to go to the last button, and to scroll to top. But I was wondering if there is anyone that can give insights on whether I can use the scroll bar on the side of that scrollview in order to help me navigate the scrolling better.
That bad boy isn't a scroll bar. It's simply a visual indicator of the current location. There are ways to scroll programmatically, but I'm not sure that's really what you want to do.

How can I implement swipe to see more options? There are lot of libraries that I could readily use, but they all are designed for iPhone apps. In iPad you have a lot of space, and I want to stack the buttons vertically instead of horizontally.
Is there any library for this? If not, how should I go about building this as a custom cell?
I tried building a custom UITableViewCell class which adds a UIScrollView, but it's not the same as showing the buttons beneath the cell.
Based on your inputs I have created a simple custom cell with basic functionality of swipe to see utility buttons and of course buttons stacked vertically.
What I did was, add a UIView beneath the cell's content view and positioned at right. Now depending on the number of buttons provided each button's height is adjusted accordingly. And delegates are provided for button clicks.
Swipe gestures are added. On swiping left it will animate and shift the cell's content view to reveal the button view. On swiping right it will reset the cell to original position.
You can customise it from here onwards as you wish :)

I have a UIScroll view that scrolls between 4 different XIBs. I would like to disable the ability of scrolling by touching the scroll view. There are two buttons at the bottom of my app that I would like to scroll forward and back in a loop. The ViewController is forced to be in landscape orientation, and the scroll view dimensions are 568w x 217h.
Here is an image of the layout: Click Here
What you are tying to do is called "paging", and in my opinion a scroll view in not the best way to do so... here is a great project that looks like what you need:

I would like it to appear the keyboard is pushing another view up. The problem is there is a UITabbar between the UIView I would like to animate in unison with the keyboard, problem being the UITabbar breaks up what would give that appearance. What I would really like to be able to do is detect when the keyboard is at the exact point my view then animate that view.
Is this possible without going into the private API's?
Too be clear I have the animation working, just working out a way to make it smoother. The effect I am trying to create is similar to the messages app, but there is a UITabbar between to UIView and the bottom of the screen.
Perhaps this will work...
The height of the keyboard on the iPhone is 216 pixels. The default animation duration for the keyboard display is 0.25 seconds.
The height for a tab bar is 44 pixels.
So, if you started the UIView transition animation afterDelay:((44.0/216.0) * 0.25), this should look right on an iPhone. Perhaps try and see?
If this works, it's pretty easy how to figure out for landscape, and iPad, etc.
Additionally, if this does work, in your final implementation, I would avoid hardcoding the 0.25.
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.
In my app I use a page control and a UIScrollView to page horizontally, I'd like to be able to enable vertical scrolling on each page. Now I know you can nest UIScrollViews in order to achieve this, there is however one problem in my project. Each of the pages uses a view controller consisting of a view, with a background image (different image for each page). This background image should not move while scrolling up and down.
Now what I want is the ability to have buttons, regular rect buttons, which I create in Interface Builder (since I want to be able to design and update the positions easily) and which then can be scrolled vertically.
So it should be like this:
You see a screen with a page-control on the bottom, above it an image with buttons over it. When you scroll sideways, you go to another page, again with an image (another one) and with different buttons. Now whenever you scroll vertically on a page, the buttons should be scrollable (so I can have a LOT of buttons on 1 page), but the image should maintain it's position.
So I figured, I just add another scroll view on top of the view with the background image. This works fine since I now have my buttons hovering over the background image and I have a separate nib file for each page including the buttons. But when I do it like this, the scrollview with the buttons becomes un-scrollable vertically. I don't know why this is happening, so could anyone suggest me how to achieve the wanted result?
I'd be really really grateful!
Thanks,
Fabian
