The three major mobile platforms, Android, iOS, Windows Phone, let's talk about them one by one. Windows Phone Platform Let’s start with WP. The pop-up prompts in the WP platform are called “raw notifications”, which continue the design whatsapp database principles of the Win desktop platform. figure 1 As shown in Figure 1, the operation button in the dialog is called "Commit button", the positive operation is on the left, and the negative operation is on the far right. Win platform defines specific usage and sequence iOS platform The iOS platform, its origin whatsapp database and history are destined to inherit the design of OS X. Contrary to Win (or Win is intended to be the opposite of OS X. Positive operations are on the right, and negative operations are on the left.
Image 3 OS X users expect all keys to be at the bottom right of the dialog, and the key that initiates an action is always at the far right. This button is called "Action button" to confirm the most important action of the current dialog. The Cancel button whatsapp database is located to the left of the "Action button" (Figure 3 left). OS X Interface Guidelines, Portal (see Dialog chapter) iOS inherits the design principles of OS X (right in Figure 3), but it is slightly different, which is reflected in the understanding of Cancel: 1. When the operation involves potential risks, the "Cancel" button whatsapp database of the two buttons should be located on the right side and highlighted. 2. When it is necessary to guide people to perform the desired operation.
The iOS platform is more interested in the highlighted state of the button (the highlighted state of iOS is always on the right side, OS X is not). At the same time, pressing the Home button when the dialog pops up should be equivalent to clicking whatsapp database the "Cancel" button and does not perform any operation. iOS Human Interface Guidelines, portal (see alert description) Android platform Android platform, this is the most troublesome guy, most of the pits are here. When it first debuted, it may be due to the implementation of the design specifications and the fragmentation of the Android system at that time, which led to the operation button sequence in the dialog whatsapp database depending on the preferences of each application developer, and most of them are consistent with the Win platform.
