適配iphone6/6+啓動界面

若是舊的工程直接跑到這兩個模擬器中時，默認是"兼容模式"，即系統會簡單的把內容等比例放大，顯示效果有些模糊但尚可接受。此時App內部獲取到的設備分辨率和iPhone5是同樣的：320*568 point。

啓用高分辨率模式有2個方法：

1.添加大屏的LaunchImage:

在Images.xcassets裏，刪除舊的LaunchImage組，而後新建LaunchImage組，添加對應高分辨率的圖片。（參考：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，它用一個xib文件來做爲啓動畫面。App在舊版iOS（低於ios8）啓動時，該屬性會被自動忽略，不會形成異常。

首先，點擊New File ->iOS User Interface ->Launch Screen，而後在工程設置項裏啓用它：

LaunchFile

不過這個xib不能關聯任何的代碼（不能自定義View的Class，不能IBOutlet，不能加Object），能夠理解成這個xib就是一張截圖，這個方案的好處在於可使用到Size Classes來針對不一樣屏幕布局這個xib。

上面兩處設置，只要啓用任意一個便可讓App進入高分辨率模式；但若是兩處都沒有設置，則App會回退到兼容模式。

兩處都設定的話在ios8會走Launch Screen File，在低於ios8 走LaunchImage

PS：iPhone四、iPhone五、iPhone6這幾個設備的ppi都是相同的，默認圖片優先是@2x。iPhone6 Plus的像素密度更高，默認圖片優先是@3x。另外，iPhone6 Plus有一點和其餘設備不一樣：在App內部得到的屏幕分辨率是1242*2208，但設備實際分辨率是1920*1080，這時系統會把總體的顯示內容作一個縮放，downscale到1/1.15。

UIPageControl的autoresizingMask

在設置UIPageControl實例的寬度時，顯示的好像老是設置的四倍左右，可是把其餘組建（UILable等）設置在同一父容器中顯示的是正常的。頭文件看到UIPageControl的autoresizingMask默認值是UIViewAutoresizingNone，可是感受沒起做用，因而這是下

Java代碼

_mainPageControl.autoresizingMask = UIViewAutoresizingNone;

        _mainPageControl.autoresizingMask = UIViewAutoresizingNone;

UIPageControl顯示正確了。（apple的bug？）

UIActivityViewController crashing on iPads by sdk8

其老早在 https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIActivityViewController_Class/ 中就說了：On iPad, you must present the view controller in a popover. On iPhone and iPod touch, you must present it modally。

在sdk8以前你ipad仍是用了presentViewController，那在dismissViewControllerAnimated的時候屏幕會旋轉下，可能你還能接受，可是在sdk8便會直接crash，報錯：

Java代碼

2014-10-15 14:03:25.927 BT2014[5133:488272] *** Terminating app due to uncaught exception 'NSGenericException', reason: 'UIPopoverPresentationController (<_UIAlertControllerActionSheetRegularPresentationController: 0x145578890>) should have a non-nil sourceView or barButtonItem set before the presentation occurs.'

因此用sdk8編譯時ipad用pop，而且用新類：UIPopoverPresentationController

UIActivityViewController

"LaunchServices: invalidationHandler called" with UIActivityViewController iOS8

In iOS8 when I present or dismiss a UIActivityViewController, my app logs: "LaunchServices: invalidationHandler called"。

多是蘋果的issue

ios sdk8/ios8 remoteNotification

//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

在蘋果UIApplication文件中說明：

@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 systemwide settings; doesn't relate to connectivity.

- (UIRemoteNotificationType)enabledRemoteNotificationTypes NS_DEPRECATED_IOS(3_0, 8_0, "Please use -[UIApplication isRegisteredForRemoteNotifications], or -[UIApplication currentUserNotificationSettings] to retrieve user-enabled remote notification and user notification settings");

@end

因此在ios8中應該用的新的註冊通知的代碼：

C代碼

// IOS8 新的註冊api
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
{
[[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings
settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge)
categories:nil]];
[[UIApplication sharedApplication] registerForRemoteNotifications];
}
else
{
//原來註冊通知的代碼
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
(UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
}

   // IOS8 新的註冊api
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
    {
        [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings
                                                                             settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge)
                                                                             categories:nil]];
        
        
        [[UIApplication sharedApplication] registerForRemoteNotifications];
    }
    else
    {
        //原來註冊通知的代碼
        [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
         (UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
    }

本來在IOS7當中判斷push是否打開的方法是：

Java代碼

UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
return (types & UIRemoteNotificationTypeAlert);

UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
return (types & UIRemoteNotificationTypeAlert);

若是將這段代碼使用在 IOS8當中，雖然不會出現crash的現象，但永遠返回空。在IOS8中，咱們使用以下的新代碼來取代以上的代碼：

Java代碼

+(BOOL)enabledRemoteNotification{
UIRemoteNotificationType types;
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
{
types = [[UIApplication sharedApplication] currentUserNotificationSettings].types;
}
else
{
types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
}
return (types & UIRemoteNotificationTypeAlert);
}

+(BOOL)enabledRemoteNotification{
    UIRemoteNotificationType types;
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
    {
        types = [[UIApplication sharedApplication] currentUserNotificationSettings].types;
    }
    else
    {
        types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
    }
    
    
    return (types & UIRemoteNotificationTypeAlert);
}
