如果要兼容IOS8在IOS中實現本地推送,關鍵是要注意:ios8在實現本地推送時需要通過如下語句進行注冊。
[[UIApplication sharedApplication] registerUserNotificationSettings:mySettings];
至於IOS8之前版本的做法就不多說了,直接上代碼。新建oc類文件(NotificationHelper),在NotificationHelper.h中聲明相關方法如下:
#import <UIKit/UIKit.h> @interface NotificationHelper:NSObject <UIApplicationDelegate> { } -(void) addNotifiction:(NSString*) firedate keyA:(NSString*)key messageA:(NSString*)message
-(void)removeLocalNotificationByKey:(NSString*)key;
-(void)removeLocalAllNotification;
-(void) registerLocalNotification:(UIApplication*)application;
+(NotificationHelper*) shareInstance;
@end
在NotificationHelper.m文件中實現方法如下:
#import "NotificationHelper.h" @implementation NotificationHelper static NotificationHelper* instance; //實現單例 +(NotificationHelper*) shareInstance { static dispatch_once_t onceToken ; dispatch_once(&onceToken, ^{ instance = [[super allocWithZone:NULL] init] ; }); return instance ; } //推送處理[注冊消息通知] -(void) registerLocalNotification:(UIApplication*)application { application.applicationIconBadgeNumber = 0;//清除應用圖標上的數字
//關鍵:加上版本的控制 #if __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_8_0 // The following line must only run under iOS 8. This runtime check prevents // it from running if it doesn't exist (such as running under iOS 7 or earlier). UIUserNotificationType types = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert; UIUserNotificationSettings *mySettings = [UIUserNotificationSettings settingsForTypes:types categories:nil]; if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) { [[UIApplication sharedApplication] registerUserNotificationSettings:mySettings]; } #endif } -(void) addNotifiction:(NSString*) firedate keyA:(NSString*)key messageA:(NSString*)message { NSLog(@"addNotifiction"); UILocalNotification *localNotification = [[UILocalNotification alloc] init]; NSDateFormatter *formatter = [[NSDateFormatter alloc] init]; [formatter setDateFormat:@"HH:mm:ss"]; NSDate *now = [formatter dateFromString:firedate];//觸發通知的時間
//如果firedate傳入的是XX:XX:XX格式在表示在固定的時間點發送通知,如果傳入的是XX格式表示從現在開始XX秒後發送通知 if(now == nil) { NSTimeInterval secs = [firedate doubleValue]; now = [NSDate dateWithTimeIntervalSinceNow:secs]; } localNotification.fireDate = now; //設置 時區 localNotification.timeZone = [NSTimeZone defaultTimeZone]; // 觸發後,彈出警告框中顯示的內容 localNotification.alertBody = message; localNotification.alertAction = NSLocalizedString(@"View Details", nil); // 觸發時的聲音(這裡選擇的系統默認聲音) localNotification.soundName = UILocalNotificationDefaultSoundName; // 觸發頻率(repeatInterval是一個枚舉值,可以選擇每分、每小時、每天、每年等) localNotification.repeatInterval = kCFCalendarUnitDay;//測試用暫時寫死為每隔一天 0:不重復
// 需要在App icon上顯示的未讀通知數(設置為1時,多個通知未讀,系統會自動加1,如果不需要顯示未讀數,這裡可以設置0)
localNotification.applicationIconBadgeNumber = 1;
// 設置通知的id,可用於通知移除,也可以傳遞其他值,當通知觸發時可以獲取
localNotification.userInfo = @{@"id" : key};
// 注冊本地通知
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
[localNotification release];
}
/** removeLocalNotificationByKey */ - (void)removeLocalNotificationByKey:(NSString*)key { // 取出全部本地通知 NSArray *notifications = [UIApplication sharedApplication].scheduledLocalNotifications; // 設置要移除的通知id NSString *notificationId = key; // 遍歷進行移除 for (UILocalNotification *localNotification in notifications) { // 將每個通知的id取出來進行對比 if ([[localNotification.userInfo objectForKey:@"id"] isEqualToString:notificationId]) { // 移除某一個通知 [[UIApplication sharedApplication] cancelLocalNotification:localNotification]; } } } - (void)removeLocalAllNotification { [[UIApplication sharedApplication] cancelAllLocalNotifications]; } @end
用法舉例:
比如在應用啟動的時候調在didFinishLaunchingWithOptions方法中調用:
[[NotificationHelper shareInstance] registerLocalNotification:application];
進行注冊和版本控制,在需要發送通知的時候調用:
[[NotificationHelper shareInstance]addNotifiction:"18:30:30" keyA:"key" messageA:"可以領取體力了!" ]
完畢。由於公司的手游項目需要使用到本地推送,而我們的項目是用quick cocos2d-x引擎,前端使用LUA編寫腳本和界面。這樣就面臨一個問題:如何編寫友好的接口讓lua能夠調用oc來實現推送,這樣的話所有的邏輯都在lua中實現。
下次有空再說。
