iOS本地推送

                       iOS本地推送

第一步：创建本地推送

// 创建一个本地推送

UILocalNotification *notification = [[[UILocalNotification alloc] init] autorelease];

//设置10秒之后

NSDate *pushDate = [NSDate dateWithTimeIntervalSinceNow:10];

if (notification != nil) {

// 设置推送时间

notification.fireDate = pushDate;

// 设置时区

notification.timeZone = [NSTimeZone defaultTimeZone];

// 设置重复间隔

notification.repeatInterval = kCFCalendarUnitDay;

// 推送声音

notification.soundName = UILocalNotificationDefaultSoundName;

// 推送内容

notification.alertBody = @"推送内容";

//显示在icon上的红色圈中的数子

notification.applicationIconBadgeNumber = 1;

//设置userinfo 方便在之后需要撤销的时候使用

NSDictionary *info = [NSDictionary dictionaryWithObject:@"name"forKey:@"key"];

notification.userInfo = info;

//添加推送到UIApplication

UIApplication *app = [UIApplication sharedApplication];

[app scheduleLocalNotification:notification];

}

第二步：接收本地推送

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification*)notification{

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"iWeibo" message:notification.alertBody delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil];

[alert show];

// 图标上的数字减1

application.applicationIconBadgeNumber -= 1;

}

第三步：解除本地推送

// 获得 UIApplication

UIApplication *app = [UIApplication sharedApplication];

//获取本地推送数组

NSArray *localArray = [app scheduledLocalNotifications];

//声明本地通知对象

UILocalNotification *localNotification;

if (localArray) {

for (UILocalNotification *noti in localArray) {

NSDictionary *dict = noti.userInfo;

if (dict) {

NSString *inKey = [dict objectForKey:@"key"];

if ([inKey isEqualToString:@"对应的key值"]) {

if (localNotification){

[localNotification release];

localNotification = nil;

}

localNotification = [noti retain];

break;

}

}

}

//判断是否找到已经存在的相同key的推送

if (!localNotification) {

//不存在初始化

localNotification = [[UILocalNotification alloc] init];

}

if (localNotification) {

//不推送 取消推送

[app cancelLocalNotification:localNotification];

[localNotification release];

return;

}

}
