ios UIApplocation 中APP启动方式

iOS app启动的方式有哪些：

自己启动（用户手动点击启动）
urlscheme启动（关于urlScheme的详解）http://www.cnblogs.com/sunfuyou/p/6183064.html
本地通知启动（自己写的本地通知启动，蓝牙模块的启动，地理围栏的启动）
远程通知启动（后台服务器的推送通知）

//APPdelegate.m中写上这个方法

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

//系统中自带的launchoption的字典里面的所有key

UIKIT_EXTERN NSString *const UIApplicationLaunchOptionsURLKey NS_AVAILABLE_IOS(3_0); // userInfo contains NSURL with launch URL

UIKIT_EXTERN NSString *const UIApplicationLaunchOptionsSourceApplicationKey NS_AVAILABLE_IOS(3_0); // userInfo contains NSString with launch app bundle ID

UIKIT_EXTERN NSString *const UIApplicationLaunchOptionsRemoteNotificationKey NS_AVAILABLE_IOS(3_0) __TVOS_PROHIBITED; // userInfo contains NSDictionary with payload

UIKIT_EXTERN NSString *const UIApplicationLaunchOptionsLocalNotificationKey NS_AVAILABLE_IOS(4_0) __TVOS_PROHIBITED; // userInfo contains a UILocalNotification

UIKIT_EXTERN NSString *const UIApplicationLaunchOptionsAnnotationKey NS_AVAILABLE_IOS(3_2); // userInfo contains object with annotation property list

UIKIT_EXTERN NSString *const UIApplicationProtectedDataWillBecomeUnavailable NS_AVAILABLE_IOS(4_0);

UIKIT_EXTERN NSString *const UIApplicationProtectedDataDidBecomeAvailable NS_AVAILABLE_IOS(4_0);

UIKIT_EXTERN NSString *const UIApplicationLaunchOptionsLocationKey NS_AVAILABLE_IOS(4_0); // app was launched in response to a CoreLocation event.

UIKIT_EXTERN NSString *const UIApplicationLaunchOptionsNewsstandDownloadsKey NS_AVAILABLE_IOS(5_0) __TVOS_PROHIBITED; // userInfo contains an NSArray of NKAssetDownload identifiers

UIKIT_EXTERN NSString *const UIApplicationLaunchOptionsBluetoothCentralsKey NS_AVAILABLE_IOS(7_0); // userInfo contains an NSArray of CBCentralManager restore identifiers

UIKIT_EXTERN NSString *const UIApplicationLaunchOptionsBluetoothPeripheralsKey NS_AVAILABLE_IOS(7_0); // userInfo contains an NSArray of CBPeripheralManager restore identifiers

UIKIT_EXTERN NSString *const UIApplicationLaunchOptionsShortcutItemKey NS_AVAILABLE_IOS(9_0) __TVOS_PROHIBITED; // userInfo contains the UIApplicationShortcutItem used to launch the app.

// Key in options dict passed to application[will | did]FinishLaunchingWithOptions and info for UIApplicationDidFinishLaunchingNotification

UIKIT_EXTERN NSString *const UIApplicationLaunchOptionsUserActivityDictionaryKey NS_AVAILABLE_IOS(8_0); // Sub-Dictionary present in launch options when user activity is present

UIKIT_EXTERN NSString *const UIApplicationLaunchOptionsUserActivityTypeKey NS_AVAILABLE_IOS(8_0); // Key in user activity dictionary for the activity type

判断启动代码如下:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

　　// Override point for customization after application launch.

　　//用户自己点击启动

　　if(!launchOptions)

　　{

　　 NSLog(@"用户点击app启动");

} else {

　　　　NSURL *url = [launchOptions objectForKey:UIApplicationLaunchOptionsURLKey];

　　　　//app 通过urlscheme启动

　　　　if (url) {

　　NSLog(@"app 通过urlscheme启动 url = %@",url);

　　}

　　　　UILocalNotification *localNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];

　　　　//通过本地通知启动

　　　　if(localNotification)

　　　　 {

　　 NSLog(@"app 通过本地通知启动 localNotification = %@",localNotification);

　　}

　　　　NSDictionary *remoteCotificationDic = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];

　　　　//远程通知启动

　　　　if(remoteCotificationDic)

　　　　{

　　 NSLog(@"app 通过远程推送通知启动 remoteCotificationDic = %@",remoteCotificationDic);

　　}

　　return YES;

}

//位置变动的通知

if(launchOptions[@"UIApplicationLaunchOptionsLocationKey"])

{

　　　　　　//写你的重新定位的代码

}

总结：当launchOptions为空时是用户自己点击app启动，不为空时，要根据相应的key是否存在来判断是通过哪种方式启动的。
