定时推送

// 定时推送的方法

- (void)addLocalNotification

{

// 创建一个本地推送

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

// 获得 UIApplication

UIApplication *app = [UIApplication sharedApplication];

//获取本地推送数组

NSArray *localArray = [app scheduledLocalNotifications];

if (localArray) {

for (UILocalNotification *noti in localArray) {

NSDictionary *dict = noti.userInfo;

if (dict) {

if ([[dict objectForKey:@"ID"] isEqualToString:self.home.ID]) {

[app cancelLocalNotification:noti];

break;

}

}

}

}

NSLog(@"%@", localArray);

if (notification != nil) {

// 设置推送时间

notification.fireDate = _datePicker.date;

// 设置时区

notification.timeZone = [NSTimeZone defaultTimeZone];

// 设置重复间隔

notification.repeatInterval = 0;

// 推送声音

notification.soundName = UILocalNotificationDefaultSoundName;

// 推送内容

NSString *bodyStr = [NSString stringWithFormat:@"快来和我一起做%@吧😄", self.home.title];

notification.alertBody = bodyStr;

//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 dictionaryWithObjectsAndKeys:self.home.ID,@"ID", self.home.title, @"title", nil];

notification.userInfo = info;

//添加推送到UIApplication

UIApplication *app = [UIApplication sharedApplication];
