SIG ABORT problem when lowEstimate is not returned

[pirtil]

I got response where estimated prices were not available. It caused app to crash.
Log:

2014-08-30 15:22:08.236 UberKitDemo[5996:4007] Object being sent to price {

My fix:
UberPrice.m, line 40:
_lowEstimate = -1;
_highEstimate = -1;
NSString *lowE = [dictionary objectForKey:@"low_estimate"];
NSString *highE = [dictionary objectForKey:@"high_estimate"];
if ( ![lowE isKindOfClass:[NSNull class]] )
_lowEstimate = [lowE intValue];
if ( ![highE isKindOfClass:[NSNull class]] )
_highEstimate = [highE intValue];

UberKit.m, line 92:
for(int i=0; i<prices.count; i++)
{
NSLog(@"Object being sent to price %@", [prices objectAtIndex:i]);
UberPrice *price = [[UberPrice alloc] initWithDictionary:[prices objectAtIndex:i]];
if ( price.lowEstimate > -1) //added this
[availablePrices addObject:price];
}

Hey there,
The crash appears to occur because UberKit assumes a value for every field even though sometimes the Uber API doesn't return a value for some fields, in this case, for a metered cab. Your solution to the issue seems apt. I just pushed an update that features your solution.
Thanks,
Sachin
