I have time intervals in MutableArray like
NSMutableArray *times=[[NSMutableArray alloc]initWithObjects:#"6:00 AM", #"6:15 AM", #"6.30 AM", #"6:45 AM", nil];
Now i want to display notifications, when iphone local system time matches to that MutableArray time intervals notification has to display at every intervals. Please help me in this problem and send me the code. Thank you in advance.
Hope this helps all who are looking out for the solution.
How To set Custom repeat interval For Nslocal Notification.....?
How to set Local Notification repeat interval to custom time interval?
iOS - how to compare two times?
I guess there is no straight forward way to identify it.
You just need to write a logic on this like first get system's current time and match it with your mutable array and check for the time difference between first time array(Or array which is very close to system time)these two and put up a notification after that time difference change. Then there you go now you can identify when the array time and system time matches.
You can use repeatInterval to repeat the notification. Try like this..
localNotification.repeatInterval=NSMinuteCalendarUnit;

This question is best stated in an example:
It is currently 9:00am. User wants to do activity at 4:00pm the following day. They use UIDatePicker to select 4:00pm the next day, and then hit a button. I know firebase does times in milliseconds from 1970, so what I want to do is "add" the number of milliseconds from 9:00am to 4:00pm the following day to the ServerValue.timestamp(), like so:
activitiesRef.child(newActivity.id).setValue([
"id": newActivity.id,
"name": newActivity.name,
"isActive": newActivity.isActive,
"locString": newActivity.locationString,
"locLat": newActivity.locLat,
"locLong": newActivity.locLong,
"privacySetting": newActivity.privacySetting,
"targetTime": ServerValue.timestamp()]) // + some added value of time
//"targetTime": [".sv": "timestamp"]])
The reason for this is because I will be displaying a countdown timer elsewhere in the app until it reaches the targetTime. If I can push to firebase the targetTime, then the countdown timer will be a simple comparison of the current time on the user's phone to the targetTime itself.
The error I keep getting when trying to add a double value to the ServerValue.timestamp() is "Contextual type 'Any' cannot be used with dictionary literal"
If it is not possible to do so, what other options do I have? Thank you.
ServerValue.timestamp() is not a number that you can use to perform date arithmetic. It's a special placeholder value that the server side interprets with its sense of time.
The best you can do is write the timestamp, read it back out as a number, then perform math on it.
Anyone know if there's a way to generate URL's for SoundCloud tracks that specify a start time for the song? I'm looking for a way to force playback of streams at a certain time in the stream without having to do any processing on my end via the API.
As #bsz correctly noticed, we have released a way of specifying start time on the sound when linking to it, append #t=12s to the sound's URL to start it at 12th second, etc.
If the audio is long enough, you can use (e.g.) #t=2h10m12s.
They seem to have added a #t option but not sure if you can also give an stop time:

You can also specify a start time one minute or over by appending
#XmXs
If you want a time right on the minute mark (e.g. 3:00), include 0 seconds (0s) in the time code (i.e. 3m0s), or else the start time will be ignored. It does not appear to support a start time over an hour.

i am New to iphone Development .I Am Trying To Use NslocalNotification In My Project I Need To Give Remeinder For Every 2Hours or For Every Two Days Or For Every Two Months Etc..Currently I am Using NslocalNotification Repeat Interval .But Its Working For Only Every Minute For Every Hour using Nscalender ....
NSString *InterVal=[freQuencyArr objectAtIndex:index-2];
NSString *InterValType=[freQuencyArr objectAtIndex:index-1];
if(![InterVal isEqualToString:#"Every"])
{
result=[InterVal intValue];
}else
result=1;
if([InterValType isEqualToString:#"Day"]){
notification.repeatInterval= NSDayCalendarUnit;
}else if([InterValType isEqualToString:#"Week"]){
notification.repeatInterval= NSWeekCalendarUnit;
}
else if([InterValType isEqualToString:#"Month"]){
notification.repeatInterval= NSMonthCalendarUnit;
}else if([InterValType isEqualToString:#"days"]){
notification.repeatInterval=result*24*60*60;
}
here If result is 2 depend Up on IntervalType I Need Notification
its Not Working With Me
if([InterValType isEqualToString:#"days"]){
notification.repeatInterval=result*24*60*60;
}

If you look at the link I have posted in this answer, You will come to know that I have tried every possible solution here to try and do what you want currently.
I had tried all this to implement it in my app, but this doesn't work.
I am afraid to say this but this is not possible. It only allows the unit NSCalendarUnit objects to be set as a repeat interval.
I invested almost 2 months (I asked the question in Dec 2010 and answered it myself in February 2011) to try and implement every possible solution available on internet through different articles and different forums but none did help.
Check out my link and lookout for all the answers if something is useful to you.
How to set Local Notification repeat interval to custom time interval?
Really Hope that this helps you.
The repeatInterval property of a UILocalNotification cannot be used to repeat less than every one calendar unit, i.e. every day, every week, every month, etc.
Instead, you will have to schedule multiple notifications to achieve the desired effect, setting the fireDate property accordingly.
As lemnar says you are unable to use repeatInterval to repeat in a frequency different from the calendar units Apple provided. So, the code below:
if([InterValType isEqualToString:#"days"]){
notification.repeatInterval=result*24*60*60;
}
Will not do anything. I am also using repeat notifications in an app that I have built and the way I've gotten around this is by creating multiple notifications each repeating to give the "desired" repeat frequency. As an example, if I want to repeat "every 2 days", I can't do this using repeatInterval. However, I have a "scheduling function" in my app that creates multiple individual notifications to achieve this. I do this going out an arbitrary length of time (in my case, one week). So in the example above, when the user specifies that he / she needs a notification every two days from today, I create 3 notifications (one each for day 3, 5, and 7).
For repeating at a frequency less than a calendar unit, things are a little easier. Say I need to repeat every 12 hours (at 6AM and 6PM). Then, I would create 2 notifications (one for 6AM and another for 6PM). I would then set the repeatInterval for each of these notifications to NSDayCalendarUnit. This way I have created a set of notifications that repeat every 12 hours.
When my app loads, I go out another 7 days and recreate notifications as needed. Not the most elegant solution, but this was the best way I could think of getting around the repeatInterval limitation.
In my iPhone application, I need to calculate the time difference between the time a message was created on the server, and the time my phone received it.
The server (Java) puts in a number returned by System.currentTimeMillis() as metadata along with the message.
How do I compare this number with the current time on the device? Could not find a suitable NSDate method to do this comparison.
Thanks in advance!
You might take a look at this SO answer and the -timeIntervalSinceDate: method.
You can use (NUInteger) ([[NSDate date] timeIntervalSince1970] * 1000)
I am new to iPhone programming so am hoping someone can help me out here. I have searched the web, but can only find information on count down timers.
What I am looking to do is start a count up timer when a button is pressed and then stop it when a certain value drops by, say 5, and finally display that time. I can display values on screen once I have them, but getting the time in the first place is proving difficult for me.
I apologize if this is a simple question, but I look forward to reading your responses.
Thanks in advance,
stu
NSDate will provide the current date. You can use - (NSTimeInterval)timeIntervalSinceNow
to get the time since the first call and now.
There's no difference between an up-counter and down-counter. Just change the order of your subtraction.
UpcounterElapsedTime = UpcounterCurrentTime - UpcounterStartTime;
DowncounterElapsedTime = DownCounterStartTime - DownCounterCurrentTime;
