iOS本地推送的實現，相容iOS8

iOS本地推送的實現，相容iOS8

AppDelegate.m中的代碼

// AppDelegate.m中- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    // 處理iOS8本地推送不能收到的問題    float sysVersion=[[UIDevice currentDevice]systemVersion].floatValue;    if (sysVersion>=8.0) {        UIUserNotificationType type=UIUserNotificationTypeBadge | UIUserNotificationTypeAlert | UIUserNotificationTypeSound;        UIUserNotificationSettings *setting=[UIUserNotificationSettings settingsForTypes:type categories:nil];        [[UIApplication sharedApplication]registerUserNotificationSettings:setting];    }    return YES;}

// 接收本地推送（AppDelegate.m中添加）- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification{    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"標題" message:notification.alertBody delegate:nil cancelButtonTitle:@"確定" otherButtonTitles:nil];    [alert show];        // 表徵圖上的數字減1    application.applicationIconBadgeNumber -= 1;}

- (void)applicationWillEnterForeground:(UIApplication *)application {    // 直接開啟app時，表徵圖上的數字清零    application.applicationIconBadgeNumber = 0;}

在調用的類中添加的代碼

// 進行推送的方法// 設定本地推送參數，並進行推送- (void)scheduleNotification{    UILocalNotification *notification = [[UILocalNotification alloc] init];    //設定5秒之後    NSDate *pushDate = [NSDate dateWithTimeIntervalSinceNow:5];    if (notification != nil) {        // 設定推送時間（5秒後）        notification.fireDate = pushDate;        // 設定時區（此為預設時區）        notification.timeZone = [NSTimeZone defaultTimeZone];        // 設定重複間隔（預設0，不重複推送）        notification.repeatInterval = 0;        // 推送聲音（系統預設）        notification.soundName = UILocalNotificationDefaultSoundName;        // 推送內容        notification.alertBody = @"推送主體內容";        //顯示在icon上的數字        notification.applicationIconBadgeNumber = 1;        //設定userinfo 方便在之後需要撤銷的時候使用        NSDictionary *info = [NSDictionary dictionaryWithObject:@"name"forKey:@"key"];        notification.userInfo = info;        //添加推送到UIApplication        UIApplication *app = [UIApplication sharedApplication];        [app scheduleLocalNotification:notification];    }}
