Answer 1

After your line

NSArray *steps=[[aary objectAtIndex:0]valueForKey:@"steps"];   

replace lines with this may work

NSMutableArray *polyLinesArray = [[NSMutableArray alloc] init];

for (int i = 0; i < [steps count]; i++)
{
    NSString* encodedPoints = [[[steps objectAtIndex:i] objectForKey:@"polyline"] valueForKey:@"points"];
    MKPolyline *route = [self polylineWithEncodedString:encodedPoints];
    [polyLinesArray addObject:route];
}

[self.mapView addOverlays:polyLinesArray];
[polyLinesArray release];
