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。
