I'm just trying to create a simple app, that would work as a wallpaper app. But i need to get the images off interwebs. So I thought I would get a rss feed of images and and basically have a rss reader that only has images. But I thought. . . I need a preview for the images in the main viewcontroller, so I would use just a image view for that, but it needs to be able to let the user be able to click on the preview image and take the user to another viewcontroller that will have the full size image. So should I try to put the preview images in a button? and let the button take the user to another viewcontroller with a full size imageview and somehow have the image display their. Sorry if this is confusing, this is the only way i thought how to do this. If their is an easier way, please tell me. And when it comes to, when the user wants to download the image online, i can just hook up some outlets for some buttons on the viewcontroller and link them together with the image, and put some code for saving the image. Would that work?
Ok, so let me get this straight:
You want to create an app that retrieves images from the internet, displays them to the user, and when the user clicks on an image, he/she is presented with a fullscreen view of that image?
There are a number of options you can pick from. Here are just a few suggestions:
You can use the image as the image for a UIButton
You can make the UIImageView call a function when it's tapped (using either a UIGestureRecognizer, or just implementing the touchesBegan: method).
You can put an invisible UIButton over the UIImageView
When displaying the image, you add an UIImageView to the UIViewController and hook it up using an IBOutlet (unless you're creating the layout in code). Then in the code, you would convert the downloaded image (NSData) into a UIImage, and then display this in the UIImageView.
It seems as you're a beginning iOS Developer, and I respect that you're trying to learn by doing. However, I suggest that you start off with reading some introductory tutorials before you begin your first project. Otherwise you might waste a lot of time. Here's a very good guide on how to get started! Good luck :)

I am developing an app that has an internal gallery with some images.
What I want to achieve is exactly a result that behaves and looks like the Apple Photo app image viewer.
With a collection view I implemented the gallery images with thumbnails and now I would like to show the image on fullscreen on press.
The image viewer should have exactly the Apple's Photo behavior:
Full screen on single tap,
Delete, Share button etc...
Pinch to zoom, double tap zoom...
My question is. Is that really possible that such a common feature is not already given by iOS? Is there maybe a view controller already build in that we can use but I am not aware of?
I know there are some libraries around that make such thing, but I'm wondering if there's already something given.
I need an advise regarding to video preview in DetailViewController. I have a tableView based app. I will have some content in my tableView and I want users to tap on the cell and go to the DetailViewController. So far, I was able to get users do this. I have the following storyboard at the moment. But it contains UIImageView in it.
IMAGE: http://cl.ly/image/0c3V121X0T0M
As you can see, I have thumbnailView and some label containing information and again UIImageView in detailViewController. My aim is to show a video on the DetailViewController instead of a UIImageView and some info related to that video. It would be better for me fetch the videos, so I don't need to push new updates every single time I make changes on the videos.
Do you happen to have an answer or any sources that can help me out with this? I have had a look at the resources available but couldn't come up with solid solution so far.
Please let me know if I should provide more regarding to my question.
You need to look at AVFoundation and AVPlayer.

ok guys im not to shure where to start with this one its a first for me but i have a floor plan that i would like to show in my IOS7 App and i know i want the user to shrink and grow the image so he or she can zoom in to areas of the map. it would be nice if they could click on the an area of the image and it would be linked to data in my parse database. but i think thats a long way off for me.....
but for now just to let the user shrink and grow and rotate the image would be nice.
anyone got any tutorials they can point me to?
Have a look at Apple's PhotoScroller example. Here an ARC-ready version.
This will not cover rotating the image, but you can easily get this by following this tutorial.
in my app and I'm using UiImagePicker also implemented UiNavigationControllerDelegate for some customizations as the delete key and the back button.
When the user browses the images from its library and chooses one, if you AllowEditing is enabled, the image picker shows a screen for cropping the photo ..
At the bottom of this view seems to be a TabBar controller with two buttons:
Choose Cancel and
I wanted to know if anyone knows how to change the text of these buttons ...
Can you help?
There is no supported API that gives you the ability to customize those buttons.
Perhaps the best solution is to find a custom replacement for UIImagePickerController. There may be one on github or Google code.
I am trying to create an app for which I need a way to swipe through views. For example, while swiping through images in photo stream or camera roll. I DO NOT need to swipe through images however, I need to swipe through UIViews. I have been looking at PageViewController. However, setViewControllers:direction:animated:completion: suggests that I need a ViewController for every UIView. This doesn't seem to be what I want since I will have over 40 views that I will need to scroll through. I think I'm missing an obvious ios feature here since even iBooks has a way to go through pages of books.
I was thinking maybe having 3 ViewControllers and changing their content whenever I swipe across. But that seems very roundabout.
Please help me out!
Thanks!
Apple has provided a fairly robust example of doing this kind of thing with photos called "PhotoScroller" at http://developer.apple.com/library/ios/#samplecode/PhotoScroller/Introduction/Intro.html. It uses UIScrollViews and CATiledLayers to recreate the experience of the Photos app. You may be able to modify it to work with your UIViews instead of images.
