Phonegap之ios对iPhone6和Plus的闪屏适配 -- xmTan

　　故事的发生起于，由于老板强烈要求app在iPhone6和5有一样的工具栏，然后前端妹子用@media为iPhone6和Plus做了样式适配。然后问题来了，竟然奇葩的发现@media样式只对iPhone4和5起了作用，然后在6和6S的样式效果和5是一样的，奇了怪了！

　　然后我去查找原因，无意中去获取设备屏幕宽高时发现了这神奇的现象：

CGRect screenBounds = [[UIScreen mainScreen] bounds];
NSString *str = NSStringFromCGRect(screenBounds);
NSLog(@"%@", str);

　　/*
　　　　iPhone4S打印结果： {{0, 0}, {320, 480}}

　　　　iPhone5和5S、还有6、6Plus、6S、6S Plus打印结果都是一样的，
　　　　为：{{0, 0}, {320, 568}}
　　*/　

　　按正常逻辑来说，6和6S的打印结果应该为：{{0, 0}, {375, 667}}, 然后6Plus和6S Plus的打印结果为：{{0, 0}, {414, 736}}

顿时感觉到这个应该是导致@medie样式对6和Plus不起作用的原因！

　　然后另外还发现了，app的启动图片，也是所谓的”闪屏”（splash），6和6S、Plus都共用了iPhone5的启动图片： Default-568h@2x~iphone.png。就算你在app的资源文件夹splash那里增加了图片：Default-667h@2x~iphone.png和Default-736h@3x~iphone.png，可是打包到6和Plus上时，加载的启动图片还是568h, 这是怎么的一回事呢？

　　然后开始的各种查，最后问题解决了，先把解决办法说一下，三个条件：

1、在ios app项目的工程文件***.info里加上针对启动图片的配置，配置内容：
