Let's discuss the Undo and Redo functionality in your app. Many apps allow people to shake the device to undo and redo certain operations, such as typing or deleting when initiated in this manner, and alert asks the user to confirm or cancel the undo or redo operation. By the way, the majority of users never use the shape to undo feature has been researched, and checked on do can be disabled or enabled in the settings. Let's quickly go over the guidelines. Briefly and precisely describe the operation to be undone and redone. The Undo and Redo alert title automatically includes a prefix of undo or redo including the trailing space.

You need to provide an additional word to describe what's been undone or redone. to appear after this perfect. For example, you might create alert titles such as undo name or redo address change. If you use the shake gesture to undo and redo, don't use it for other actions. Although you can programmatically give multiple meanings to the shake gesture, you run the risk of confusing people and making your app on projectable. Provide Undo and Redo buttons sparingly.

It's confusing when apps provide multiple ways to perform the same task. If your app truly warrants dedicated, Undo and Redo buttons, use the standard system provided icons and put them in an expected location such as a navigation bar. So the Undo redo can be in the navigation bar and in the toolbar. The system provided buttons for them are just text based Undo and Redo. I think it's a case to use the icons for these as well. counts to be in the keyboard shortcuts bar, and usually are represented by the familiar arrow icons.

These are the default undo redo for text. Same thing for the undo button within the bypass keyboard. Perform Undo and Redo operations in the current context only. Undo and Redo should have a clear and immediate effect on the current context. Not an earlier one. Of course, duh, Captain Obvious.
