为iPad和iPhone程序增加启动画面非常简单,基本思路就是增加启动图片资源Default.png即可,只是要根据不同的分辨率和旋转方向需要有不同的图片尺寸。
目前的iOS设备有三种不同的分辨率:
1 | iPad 768x1024 |
2 | iPhone4 640x960 |
3 | iPhone 320x480 |
如果一个程序,既要支持iPad又要支持iPhone,那么它需要包含下面几个图片:
1 | Default-Portrait.png iPad专用竖向启动画面 768x1024或者768x1004 |
2 | Default-Landscape.png iPad专用横向启动画面 1024x768或者1024x748 |
3 |
|
4 | Default-LandscapeLeft.png iPad专用横向启动画面(可省略), 1024x768或者1024x748 |
5 | Default-LandscapeRight.png iPad专用横向启动画面(可省略), 1024x768或者1024x748 |
6 |
|
7 | Default@2x.png iPhone4启动图片640x960或者640x920 |
为了在iPad上使用上述的启动画面,你还需要在xxxx_info.plist中加入key(根据下拉菜单中的可选项选择):
1 | UISupportedInterfaceOrientations |
2 | 或 Supported? interface ?orientations |
同时,为其加入值(根据下拉菜单中的可选项选择):
1 | UIInterfaceOrientationPortrait 或 Portrait (bottom home button) |
2 | UIInterfacOrientationPortraitUpsideDown 或 Portrait (top home button) |
3 | UIInterfaceOrientationLandscapeLeft 或 Landscape (left home button) |
4 | UIInterfaceOrientationLandscapeRight 或 Landscape (right home button) |

想要取消的话,直接删除default图片,之后

“Command-Option-Shift-K to clean out the build folder. Even better, quit Xcode and clean out~/Library/Developer/Xcode/DerivedData?manually. Remove?all?its contents because there's a bug where Xcode will run an old version of your project that's in there somewhere. (Xcode 4.2 will show you the Derived Data folder: choose Window > Organizer and switch to the Projects tab. Click the right-arrow to the right of the Derived Data folder name.)
?
In the simulator, choose iOS Simulator > Reset Content and Settings.
Finally, for completeness, you can delete the contents of /var/folders; some caching happens there too.”
