任何人都可以告诉我如何在不同的时间为不同的值设置通知..
假设我有一个大小为4的数组,
例如数组a = {1,2,3};
我想要的是每小时后它会显示不同数组值的通知;
第一次显示“1”,一小时后显示“2”,第三小时显示“3”。
我实现的代码只有一个值,如下所示......
NSDate *fireDate = [NSDate date];
NSArray *values= [NSArray arrayWithObjects:@"1", @"2", @"3", nil];
for (NSString *string in values )
{
// create notification...
localNotify.fireDate =[NSDate dateWithTimeIntervalSinceNow:[datePicker countDownDuration]];
localNotify.alertBody = string;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotify];
fireDate = [fireDate dateByAddingTimeInterval:67];
[localNotify setApplicationIconBadgeNumber:[[UIApplication sharedApplication] applicationIconBadgeNumber]+1];
NSLog(@"1");
}
答案 0 :(得分:4)
只需使用循环,例如:
NSDate *fireDate = [NSDate dateWithTimeIntervalSinceNow:[datePicker countDownDuration]];
for (NSString *string in values [NSArray arrayWithObjects:@"1", @"2", @"3", nil])
{
// create notification...
localNotify.fireDate = fireDate;
localNotify.alertBody = string;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotify];
fireDate = [fireDate dateByAddingTimeInterval:60 * 60]; // (1 hour)
}
