问题描述
因为出现了不同size的iPad设备，在使用LuanchImage方式设置启动图的时候就会出现黑边问题。
原因是LuanchImage中对于iPad的启动图只有两种：
768 * 1024 (@1x)
1536 * 2048 (@2x)
解决办法
方法一：
不使用LuanchImage方式，改用Infoplist文件中添加Key的方式来解决。
Key码如下：

PS:
1> UILaunchImages表示的是iPhone使用图
2> UILaunchImages~ipad表示的是iPad使用图
3> 以上是目前最全的(除了320*480,当然这个也可以加上，按需)
根据自己的应用需要在什么设备上使用就添加什么screen size的key即可。图片名称不需要带@1x、@2x、@3x。
4> 因为iPhone上有些是3倍图，所以建议iPhone和iPad都统一切好@1x、@2x、@3x三组图,然后导入到工程中即可。
方法二:
还是使用LuanchImage,自己手动添加所需元素到Contents.json中，按照格式添加。但是有一个问题是不确定未使用的subtype是啥，所以需要自己凭直觉去试验，目前本人还未尝试，大家可以测试下。
