Phonegap之ios對iPhone6和Plus的閃屏適配 -- xmTan

　　故事的發生起於，由於老闆強烈要求app在iPhone6和5有一樣的工具欄，然後前端妹子用@media爲iPhone6和Plus做了樣式適配。然後問題來了，竟然奇葩的發現@media樣式只對iPhone4和5起了作用，然後在6和6S的樣式效果和5是一樣的，奇了怪了！

　　然後我去查找原因，無意中去獲取設備屏幕寬高時發現了這神奇的現象：

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

　　按正常邏輯來說，6和6S的打印結果應該爲：{{0, 0}, {375, 667}}, 然後6Plus和6S Plus的打印結果爲：{{0, 0}, {414, 736}}

頓時感覺到這個應該是導致@medie樣式對6和Plus不起作用的原因！

　　然後另外還發現了，app的啓動圖片，也是所謂的”閃屏”（splash），6和6S、Plus都共用了iPhone5的啓動圖片： Default-568h@2x~iphone.png。就算你在app的資源文件夾splash那裏增加了圖片：Default-667h@2x~iphone.png和Default-736h@3x~iphone.png，可是打包到6和Plus上時，加載的啓動圖片還是568h, 這是怎麼的一回事呢？

然後開始的各種查，最後問題解決了，先把解決辦法說一下，三個條件：

1、在ios app項目的工程文件***.info里加上針對啓動圖片的配置，配置內容：
