Why do I see double status bars when starting my app?
问题 When starting my iPhone application, I'm seeing both the status bar from Default.png and the OS's built-in status bar, instead of just seeing the OS's status bar. What have I done wrong? 回答1: Resize your Default.png to exactly 320x480. If your Default.png is exactly 320x480, it will be displayed full screen layered below (in z-order) the status bar. (This means the user will see the real status bar, not the Default.png one.) But if your Default.png is some other size, the iPhone OS will scale
