App Icons on iPad and iPhone
在iPad和iPhone应用程序图标
/library/ios/qa/qa1686/_index.html
Q:& How are the icon files in my application bundle used on iPad and iPhone?
A:&Below are guidelines for handling icon files for iPhone-only apps, iPad-only apps, and universal apps.
If you don't provide artwork for one of the listed optional icons, the system will automatically scale one of your existing icon images to an appropriate size. It is strongly recommended that your application include artwork for all the icons listed, at the
specific sizes needed.
Prior to&&3.2, icon images were required to follow a strict naming convention.
These legacy names are still listed in the tables below along with example names for the more recent icons. Except for&iTunesArtwork, icon images included in your app can have
arbitrary names.
Note:&iOS ignores the PPI (Pixels Per Inch) of icon images. You may author your icon images at any PPI but their width and height, as measured in pixels,
must match the values in the tables below.
Important:&iTunesArtwork icon images should be in png format, but name them without the .png extension.
Icons for iPhone-only Apps
iPhone-only applications use the following icons. Items marked with &Required& must be included.
Note:&You should include images for the iPad-specific icons even if your app is not a universal app. If available, they will be used when the app is installed
on an iPad.

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：）
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，但设备实际分辨率是，这时系统会把整体的显示内容做一个缩放，downscale到1/1.15。
&UIPageControl的autoresizingMask
在设置UIPageControl实例的宽度时，显示的好像总是设置的四倍左右，但是把其他组建（UILable等）设置在同一父容器中显示的是正常的。头文件看到UIPageControl的autoresizingMask默认值是UIViewAutoresizingNone，但是感觉没起作用，于是这是下
Java代码&&
_mainPageControl.autoresizingMask&=&UIViewAutoresizingN&&
&UIPageControl显示正确了。（apple的bug？）
UIActivityViewController crashing on iPads by sdk8
其老早在&/library/ios/documentation/UIKit/Reference/UIActivityViewController_Class/ 中就说了：On iPad, you must present the view controller in a popover. On iPhone and iPod touch, you must present it modally。

ios sdk8/ios8 remoteNotification&
//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
在苹果UIApplication文件中说明：
@interface UIApplication (UIRemoteNotifications)
- (void)registerForRemoteNotificationTypes:(UIRemoteNotificationType)types NS_DEPRECATED_IOS(3_0, 8_0,&&Please use registerForRemoteNotifications and registerUserNotificationSettings: instead&);
// Returns the enabled types, also taking into account any doesn't relate to connectivity.

UIRemoteNotificationType&types&=&[[UIApplication&sharedApplication]&enabledRemoteNotificationTypes];&&
return&(types&&&UIRemoteNotificationTypeAlert);&&
如果将这段代码使用在 IOS8当中，虽然不会出现crash的现象，但永远返回空。 在IOS8中，我们使用如下的新代码来取代以上的代码：
Java代码&&
+(BOOL)enabledRemoteNotification{&&
&&&&UIRemoteNotificationType&&&
