需求：
从服务器获取到一组时间，都设置成闹铃，默认是每天循环不可修改，同时可以自定义闹铃，可选择周几循环。可以设置打开关闭或者删除。
一. 固定闹钟，每天循环。
很简单，将需要设置成闹钟的时间放入一个数组中，通过for循环设置成对应的本地推送，详情见下面的代码和注释。
/**
下载完成 添加巡逻提醒
@param array 下载来的巡逻提醒数据
*/
- (void)addLocalNotification:(NSArray *)array
{
// 设置一个按照固定时间的本地推送
NSDate *now = [NSDate date];
NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSCalendarIdentifierGregorian];
NSDateComponents *components = [[NSDateComponents alloc] init];
NSInteger unitFlags = NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay | NSCalendarUnitWeekday | NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitSecond;
components = [calendar components:unitFlags fromDate:now];
// 通过循环 将每一个时间都设置成本地推送
for (int i=0; i<array.count; i++) {
//设置时区（跟随手机的时区）
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
localNotification.timeZone = [NSTimeZone defaultTimeZone];
if (localNotification) {
// 设置推送时的显示内容
localNotification.alertBody = array[i][@"site_name"];
localNotification.alertAction = NSLocalizedString(@"All_open",@"");
// 推送的铃声 不能超过30秒 否则会自定变为默认铃声
localNotification.soundName = @"2.caf";
//小图标数字
localNotification.applicationIconBadgeNumber++;
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"HH:mm"];
NSDate *date = [formatter dateFromString:array[i][@"timer"]];
NSLog(@"date====%@",date);
//通知发出的时间
localNotification.fireDate = date;
}
//循环通知的周期 每天
localNotification.repeatInterval = kCFCalendarUnitDay;
//设置userinfo方便撤销
NSDictionary * info = @{@"infoKey":array[i][@"infoKey"],@"site_name":array[i][@"site_name"]};
localNotification.userInfo = info;
//启动任务
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}
}
自定义闹钟
将要进行循环的星期储存在一个数组里面，通过获取当前日期计算出数组中的星期分别是几号，然后按照上面的方式进行周循环。详细见下面的代码和注释。
/**
自定义闹钟 有重复
@param dict 巡逻提醒数据
@param array 要重复的日期（周几）
*/
-(void)addMineLocalNotification:(NSDictionary *)dict againTime:(NSMutableArray *)array
{
NSArray *clockTimeArray = [dict[@"timer"] componentsSeparatedByString:@":"];
NSDate *dateNow = [NSDate date];
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *comps = [[NSDateComponents alloc] init];
//[calendar setTimeZone:[NSTimeZone timeZoneWithName:@"GMT"]];
//[comps setTimeZone:[NSTimeZone timeZoneWithName:@"CMT"]];
NSInteger unitFlags = NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay | NSCalendarUnitWeekday | NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitSecond;
comps = [calendar components:unitFlags fromDate:dateNow];
[comps setHour:[[clockTimeArray objectAtIndex:0] intValue]];
[comps setMinute:[[clockTimeArray objectAtIndex:1] intValue]];
[comps setSecond:0];
//获取当前的日期以及设定好对比数据
Byte weekday = [comps weekday];
Byte i = 0;
Byte j = 0;
int days = 0;
int temp = 0;
Byte count = [array count];
Byte clockDays[7];
NSArray *tempWeekdays = [NSArray arrayWithObjects:@"日", @"一", @"二", @"三", @"四", @"五", @"六", nil];
//查找设定的周期模式
for (i = 0; i < count; i++) {
for (j = 0; j < 7; j++) {
if ([[array objectAtIndex:i] isEqualToString:[tempWeekdays objectAtIndex:j]]) {
clockDays[i] = j + 1;
break;
}
}
}
// 根据相差天数 计算出第一次响铃的日期 并设置周循环
for (i = 0; i < count; i++) {
temp = clockDays[i] - weekday;
days = (temp >= 0 ? temp : temp + 7);
NSDate *newFireDate = [[calendar dateFromComponents:comps] dateByAddingTimeInterval:3600 * 24 * days];
UILocalNotification *newNotification = [[UILocalNotification alloc] init];
if (newNotification) {
newNotification.fireDate = newFireDate;
newNotification.alertBody = dict[@"site_name"];
newNotification.applicationIconBadgeNumber++;
newNotification.soundName = @"2.caf";
newNotification.alertAction = NSLocalizedString(@"All_open",@"");
newNotification.repeatInterval = NSCalendarUnitWeekday;
NSDictionary * info = @{@"infoKey":dict[@"infoKey"],@"site_name":dict[@"site_name"]};
newNotification.userInfo = info;
[[UIApplication sharedApplication] scheduleLocalNotification:newNotification];
}
NSLog(@"Post new localNotification:%@", [newNotification fireDate]);
}
}
删除闹钟
/**
删除某一个巡逻提醒 开关关闭
@param dict 要删除的巡逻提醒数据
*/
-(void) deleteLocalNotification:(NSDictionary *)dict
{
// 获取所有本地通知数组
NSArray *localNotifications = [UIApplication sharedApplication].scheduledLocalNotifications;
for (UILocalNotification *notification in localNotifications)
{
NSDictionary *userInfo = notification.userInfo;
if ([dict[@"infoKey"] isEqualToString:userInfo[@"infoKey"]]) {
[[UIApplication sharedApplication] cancelLocalNotification:notification];
}
}
}
有一些是我自己程序中用到的代码，注意舍弃，不要被误导。
本地推送的数量是有限制的，好像是64个，不太确定。
