I just started chapter 17, when the first example of code I tried returns an error when I try to use ‘dateByAddingTimeInterval’. It’s like Xcode does not recognize this or something. Does anyone know why? I’m using Xcode 6. Thanks!
#import <Foundation/Foundation.h>
int main(int argc, const char * argv[]) {
@autoreleasepool {
// Create three NSDate objects
NSDate *now=[NSDate date];
NSDate *tomorrow=[NSDate dateByAddingTimeInterval:24.0*3600.0];
NSDate *yesterday=[NSDate dateByAddingTimeInterval:-24.0*3600.0];
// Create an array containing all three
NSArray *dateList=@[now, tomorrow, yesterday];
}
return 0;
}
