Question

I need some help with an array that I am working on.

I am pulling back some data from a JSON query and writing it into an array, and then in a second loop I am writing that array into another array but I don’t know how to read the data back out??
This is the code:-

for (NSDictionary *weather in weatherarray)
{
    int j = 1;
    NSArray *hourlyArray = [weather objectForKey:@"hourly"];
    for (NSDictionary *hourD in hourlyArray)
    {

        [multi addObject:Date];
        [multi addObject:[hourD objectForKey:@"time"]];
        [multi addObject:[hourD objectForKey:@"weatherCode"]];            
        [multi addObject:[hourD objectForKey:@"tempC"]]; 
        [multi addObject:[hourD objectForKey:@"FeelsLikeC"]];            
        [multi addObject:[hourD objectForKey:@"chanceofrain"]];            
        [multi addObject:[hourD objectForKey:@"cloudcover"]]; 
        [multi addObject:[hourD objectForKey:@"WindGustMiles"]]; 
        [multi addObject:[hourD objectForKey:@"humidity"]];             
        [multi addObject:[hourD objectForKey:@"pressure"]]; 
        j = j + 1;
    }     

    [[multi1 objectAtIndex:j] addObject:multi]; 
    i = i + 1;
} 
NSLog(@"%@", [[[multi1 objectAtIndex:1] objectAtIndex:0] objectAtIndex:1]);

}

as you can see I am trying to read the data out at the end in an NSLog but i am struggling, with this. Can anyone help please??

Answer 1

You need to define and assign multi within the for loop. So, put the line

NSMutableArray *multi = nil;

above the line [multi addObject:Date] and move your line

[[multi1 objectAtIndex:j] addObject:multi];

above the line j = j + 1;. You don’t need the i = i + 1; here, unless you are doing something with it, that is outside the scope of this code fragment.

Unless I have missed something, it should work like that.
