另外还有个启动画面的大小：

Table 2 Typical launch image dimensions

Device	Portrait	Landscape
iPhone and iPod touch	320 x 480 pixels 640 x 960 pixels ( @2x )	Not supported
iPhone 5 and iPod touch (5th generation)	640 x 1136 pixels ( @2x )	Not supported
iPad	768 x 1024 pixels 1536 x 2048 pixels ( @2x )	1024 x 768 pixels 2048 x 1536 pixels ( @2x )

这个不需要默认文件名称，直接在xcode5中拖过去LaunchImage的编辑画面即可。

如果全屏启动的时候你会发现状态栏也在，可能拦到画面会比较丑。那么可以在app启动时把状态栏隐藏掉，点击 工程名字->Info，然后鼠标放到Custom iOS Target Properties其中一行，这时右边会出来一个+号，点击+号新增一行，选择Status bar is initially hidden = YES，这样启动时状态栏就隐藏啦！
