converting NSString to NSInteger in iOS

Question

I have a string as

NSString *milliSeconds=@"1413808458821";

I tried the following to convert it to number, but None of them are giving correct value.

NSInteger number = [milliSeconds intValue];

NSInteger number = [milliSeconds integerValue];

NSInteger number = [milliSeconds longLongValue];

Please help me. Thanks in advance.

This is probably because you are running this code on a 32bit architecture, thus NSInteger is always an int and the number you're trying to convert is too big for this data type.

Try manually specifying the type to long long.

`long` == `int` https://stackoverflow.com/questions/900230/difference-between-long-and-int-data-types – Guillaume Algis Oct 21 '14 at 08:36
