Touch to save image to Photo Roll?

[amsprt]

Hey Guys,

I am brand new to this coding thing. Forty-Five years old and trying to learn.

I'm trying to build a scrolling photo album app. This part I have pretty much conquered. I'm able to get the app on my phone and scroll though the images with no warnings.

The next thing I want to add is the ability for the user to save an image for use as their Wallpaper or to email the image.

Again, very new to this so please if you can help, be as detailed as possible.

Thanks!

You can use UIImageWriteToSavedPhotosAlbum to save the photo, but you can email it without saving using MFMailComposeViewController.

Thanks! While I'm sure that will work, I have no idea as to how to implement. Could you help with a code sample and where it should be placed? Again, still trying to learn the basics. Just got Xcode 3 days ago.

Thanks again!

There's sample code in the documentation that will show you how to use MFMailComposeViewController.

A quick search on the forum will give you samples for UIImageWriteToSavedPhotosAlbum too. In simplest terms you can just pass it a UIImage object UIImageWriteToSavedPhotosAlbum(myImage, nil, nil, nil);
As for where to call it, I can't say, depends on your app, but you call it at the point where you want to save the image.
