NSString escapedEncodedPoints = [encodedPoints stringByReplacingOccurrencesOfString:@"\\\\" withString:@"\\"];

it will work

Didn’t realize you were the input in your code had padded slashes.

It’s working now.

The index reaches the length and for the calculation of longitude, the array goes out of bound in the second do..while loop.

So I added a check to break the loops before the statement as follows:

if (index >= len) return;
b = [escapedEncodedPoints characterAtIndex:index++] – 63;

But that causes the trip from 97229 to 95054 (Portland to Santa Clara) to return location points which go over the Pacific Ocean.

This used to be working a few months ago. Google started returning something different, recently.

Please help. If unable to recreate please let me know and I will provide more info.
