How to Select Multiple Photos in iOS
Starting with iOS 9, Apple changed the way you can select multiple photos. You can now swipe a bunch of them, instead of tapping each one individually, making it easier to share a batch of snapshots with friends and family.
Pictures in the iOS Photos app are automatically sorted into collections by year, date, and location. Open the collection you want to select photos from. Tap Select in the upper-right corner of the screen. Drag your finger across the photos you want to select. You will see a blue check mark on each one. Drag down to select an entire row of photos. Once you’ve selected your photos, you have a couple of options. You can tap Share to share them via a variety of apps (Gmail, iCloud Photo Sharing, Twitter, etc. ). This option also lets you print photos or create a slideshow. The Trash Can icon lets you delete photos, while the Add To option lets you place them in an album.
