酷适配iphone6/6+启动界面

 

如果旧的工程直接跑到这两个模拟器中时,默认是"兼容模式",即系统会简单的把内容等比例放大,显示效果有些模糊但尚可接受。此时App内部获取到的设备分辨率和iPhone5是一样的:320*568 point。

 

启用高分辨率模式有2个方法:

1.添加大屏的LaunchImage:

在Images.xcassets里,删除旧的LaunchImage组,然后新建LaunchImage组,添加对应高分辨率的图片。(参考:http://matthewpalmer.net/blog/2014/09/10/iphone-6-plus-launch-image-adaptive-mode/)



 

2.添加Launch Screen File

Launch Screen是Xcode6和iOS8新加的功能,它用一个xib文件来作为启动画面。App在旧版iOS(低于ios8)启动时,该属性会被自动忽略,不会造成异常。

首先,点击New File ->iOS User Interface ->Launch Screen,然后在工程设置项里启用它:

LaunchFile



 不过这个xib不能关联任何的代码(不能自定义View的Class,不能IBOutlet,不能加Object),可以理解成这个xib就是一张截图,这个方案的好处在于可以使用到Size Classes来针对不同屏幕布局这个xib。

 

上面两处设置,只要启用任意一个即可让App进入高分辨率模式;但如果两处都没有设置,则App会回退到兼容模式。

两处都设定的话在ios8会走Launch Screen File,在低于ios8 走LaunchImage

 

PS:iPhone4、iPhone5、iPhone6这几个设备的ppi都是相同的,默认图片优先是@2x。iPhone6 Plus的像素密度更高,默认图片优先是@3x。 另外,iPhone6 Plus有一点和其他设备不同:在App内部获得的屏幕分辨率是1242*2208,但设备实际分辨率是1920*1080,这时系统会把整体的显示内容做一个缩放,downscale到1/1.15。
