Answer 1

For the BOOL
A string is NO if its either nil or length 0. Otherwise its YES.

NSDateFormatter’s dateFromString will convert strings to dates. You set it up with a c style formatter.

For the long use longValue as in long long myval = [mystring longLongValue];

NSString has several converters
– doubleValue
– floatValue
– intValue
– integerValue
– longLongValue
– boolValue

Use as required.
