Find out next most close date from NSDate array of times - ios

Question

How can I find out the next prayer from the array of times, I have total 6 Prayers at different times and i want to compare each one with current time and have to find out which one is most near as a next prayer, Date format also creating problems because it give always in UTC format and I have to use local time zone, I am using the following code:
NSMutableArray *arrayTimeIntervals = [[NSMutableArray alloc]init];
NSMutableArray *intervals = [[NSMutableArray alloc]init];
NSMutableArray *arrayPrayers = [[NSMutableArray alloc]init];
[arrayPrayers addObject:#{#"prayer":#"prayer 1",#"time":#"1:12 am"}];
[arrayPrayers addObject:#{#"prayer":#"prayer 2",#"time":#"5:45 am"}];
[arrayPrayers addObject:#{#"prayer":#"prayer 3",#"time":#"12:03 pm"}];
[arrayPrayers addObject:#{#"prayer":#"prayer 4",#"time":#"3:30 pm"}];
[arrayPrayers addObject:#{#"prayer":#"prayer 4",#"time":#"6:20 pm"}];
[arrayPrayers addObject:#{#"prayer":#"prayer 6",#"time":#"7:50 pm"}];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"hh:mm a"];
NSMutableArray *dates = [NSMutableArray arrayWithCapacity:arrayPrayers.count];
for (NSDictionary *timeDict in arrayPrayers)
{
NSString *timeString = [timeDict objectForKey:#"time"];
NSString *name = [timeDict objectForKey:#"prayer"];
NSDate *date = [dateFormatter dateFromString:timeString];
[dates addObject:#{#"prayer":name,#"time":timeString, #"date":date}];
}
for (int i =0 ; i<arrayPrayers.count; i++) {
NSDictionary *timeDict = arrayPrayers[i];
NSString *timeString = [timeDict objectForKey:#"time"];
//NSString *name = [timeDict objectForKey:#"prayer"];
NSDate *date = [dateFormatter dateFromString:timeString];
NSComparisonResult result = [[NSDate date] compare:date];
if(result==NSOrderedAscending){
NSLog(#"next prayer");
}else if(result==NSOrderedDescending){
NSLog(#"last prayer");
}else{
NSLog(#"current prayer");
}
if ([date earlierDate:[NSDate date]]) {
NSTimeInterval interval = [date timeIntervalSinceNow];
NSDictionary *tempDict = #{#"Prayer":timeDict,
#"Time":timeString,
#"Index":[NSString stringWithFormat:#"%d",i],
#"Interval":[NSString stringWithFormat:#"%f",interval]};
[arrayTimeIntervals addObject:tempDict];
[intervals addObject:[NSString stringWithFormat:#"%f",interval]];
}
}
NSNumber * min = [intervals valueForKeyPath:#"#min.doubleValue"];
NSUInteger index = 0;
for(int i =0 ; i<intervals.count; i++)
{
NSDictionary* dict = arrayTimeIntervals[i];
if([[dict objectForKey:#"Interval"] intValue] == [min intValue]) {
index = i;
NSLog(#"next prayer is!!!:%ld",index);
break;
}
}
NSDictionary *dict = [arrayTimeIntervals objectAtIndex:index];
NSLog(#"next prayer object is:%#",dict);
