I'm looking for some cool libraries out there to display a bunch of images in my iPad application.
I think they are already out there, and I don't have to start from scratch, but I can't find some good ones.
Check out AQGridView as well.
Check out KTPhotoBrowser, I use it in a universal app, and it works pretty good.
Also, search Github : Photo Gallery for more open-source solutions.
See the answers to these questions on Stack Overflow:

There are probably more questions about the same subject. Seek and you shall find.
I would simply create a web page with all the images, and then display it using UIWebView.
Did you want to do the coding yourself?
I found the Apple example "LazyTableImages" to be a useful and elegant way to display many images in a table view. It's important to a) keep the scrolling nice and smooth, and b) not freeze the user interface while downloading.
Have you tried using a UIImageView?

I'm building an iphone photo app. I don't know how to achieve this kind of effect on an image:
When the user drags a finger across the arrow, I want the image to be distorted accordingly. How can I achieve this? Is there any framework that makes this process simple?
Thank you.
No clue about iOS, but the look reminds me of a thin-plate spline warp. It's quite easy to implement in OpenGL, a quick Google search for example code returns plenty of hits.
From the sound of it I think your looking for the CoreImage framework. Look into the various distortion effects...in particular CIBumpDistortionLinear.
I don't have any code so check out this tutorial and read up on CoreImage.
I've been searching for an hour now and can't seem to find out how to use UIPageControl to act as a swipe between images (sort of like the weather application, but with images instead of pages).
I have 7 images and I want to use them to create an instruction manual for a game I'm developing.
I am new to developing so bear with me.
Can anyone provide links to tutorials that will show me this, or show me the code in the comments below?
Thanks.
In this tutorial, check the Paging with UIScrollView section
You can use UIPageViwController to do something similar. Here is the tutorial for it.
I want to create a area of similar colors when user touches into a point on imageview. Who knows library or technique to resolve problems for ios.

Please helping, thanks!
It looks to me like you want to create a magic wand tool, correct? I can't help you come up with a way to handle this and I don't know of any libraries that can select a group of like-colored pixels based on tolerance, but there is this article here I found. It covers implementing a magic wand tool using Objective-C. I found it in the answer to this similar question on SO.
I'm trying to create a menu for a local multi-player game that dynamically updates when peers become available on the network.
The interface I want to implement is a UIScrollView, where each page displays information about a peer. Ideally, these pages are added and removed when a peer's availability changes.
I have looked through several tutorials using UIScrollView, but they all seem to pull page information from a plist or pre-loaded array.
What I want must be possible; weather app behaves in a similar manner, dynamically adding or deleting location pages. I'm not sure where to turn for further help, though. How do I dynamically update my scroll view's contents as outside events occur?
I decided to go with UICollectionView instead, it seems to provide a better method of implementation for what I'm trying to accomplish. Thanks!
Have a look at this Ray Wenderlich Tutorial.
I've used it as a basis for doing a paged scroll and the mechanism is simple enough to extend to whatever dynamic scheme you would like.
You can check this site for Multiple Tutorials & examples for UIScrollview. The link:
is Here..
I am sure, you'll able to find some good code for your need. Hope it works for you.
I need to create a iOS app where the main screen is very similar to the Facebook iOS App. I am using a UITableView to show the different posts in the feed. My question is:
What is the best option to implement this? One option is to insert Textviews/Imageviews/labels to the table view cell and another option is to have one UIWebView in each table view cell.
I have to show a lot of pictures and texts, so maybe html will be easier.
Any experience?
If you have to show a lot of pictures and text, adding one complexity level (like HTML) is not gonna help.
I'd suggest to start researching on how you can speed that huge table up, and how to retrieve the content you want to display on each cell. For instance, you could use a parallel thread that would retrieve the content in the background as you scroll down and would store it in a cache so it doesn't have to be done several times. RestKit or (depending on your specific needs) AFNetworking are surely of some help in your case.
Also, have a look to this article (a bit old, but still interesting!) on how improve your scrolling speed: Fast scrolling (and link to github example project)
