I have a question about applying photo filters in iOS. The filter itself will not be added/adjusted by the user manually, but rather automatically applied to the photo once they categorize and upload their photo to a table view. Simply put, all photos tagged by users in category "x" will be blue in a table UI, all photos in category "B" will be yellow in table UI etc...The photos will be displayed in a view format much like VEVO (if your familiar)...
I am assuming the best way to do this would just to create a class for each category based filter?
Thanks for any help.
Try the Core Image framework, it contains specific methods to apply filters.

I only know how to display one photo with url but how about a list of photos with different urls? And it will be better to also show the name of the photo under each photo
Thanks for any hints
You can use tableview with custom cell to show the list. For more specific help please share more information or you codebase.
Hey just wondering if its possible to Select a specific image from the photolibrary and implement into a Collection View
so the idea is to have an image the user can select from the photolibrary then fill the selected image into a cell within the collection view i would also like to be able to save the image so if the user deletes the photo from the library it remains within the application ( was thinking i could save the image within firebase or NSUserdefaults?
A controller demonstrating how to select photos to display in a collection view can be found here.
If you're only going to be saving a single image, then putting it at a known path like demonstrated here would work: How to save a remote image with Swift?
If you're trying to manage multiple images, it's probably a good idea to look into Core Data and have it manage the images' UIImageJPEGRepresentation NSData for you. (Be sure to set "Store in External Record File" for the image data record if you do this!)
I'm new to Umbraco. I'm looking for a way to create a photo gallery in Umbraco 7.
Your help is much appreciated.
One way that you could do it is to add a multiple media picker to your Document Type and that would allow your editors to select multiple images to be displayed in a gallery. You can then add either some Razor directly into the View for your Document Type to display the image gallery, or add it as a partial if you want to use it on several different Views.
What would be the best way in iOS 7 to take pictures inside a custom album (Named after my application) and then show the custom album.
I mean, I could add those pictures in a group using AssetsLibrary but there's some way to show them afterwards without having to create a custom gallery?

I am writing an iPhone app. My next step is to create a card object. I know how to do this theoretically, but my problem is coming from my lack of experience in Xcode.
This is my add item page
I want the user to specify a name and then choose an icon, either from the 3 most popular choices, another page of premade options, or take their own picture and use that.
Now, how do I show those choices in a way that the user can select one and I can collect their response? Right now, they are simply buttons, I can add my background image to them, but I don't know how to record their response. I would like it to show them their selection by adding that shadow around the box.
I'm not sure if a button is the best approach.
Also, I will need the same selection behavior for the image they take themselves, but I figure if I get the icon choices to work, I can figure out using a picture taken by the user.
Thanks for any help.
I would create button "Select image" below the uiimageview.
This button would present action sheet where you would have two options
a) select form existing
b) take a picture.
Then I would probably use Grid view to present the existing icons and UIImagePicker for taking pictures :)
