Why the application itself? Because normal localization is based on the current settings of the device. In practice, some applications often require localization that is not related to device settings. For example, in a game, a player can select the

When developing cocos-2d, I learned some knowledge: On iOS, the image is automatically scaled to the Npower of 2. For example, a 1024*1025 image occupies the same memory as a 1024*2048 image. The formula for calculating the memory used by the image
