Question

I am using location manager

Undefined symbols for architecture i386:
  "_OBJC_CLASS_$_CLLocationManager", referenced from:
      objc-class-ref in ViewController.o
  "_kCLLocationAccuracyHundredMeters", referenced from:
      -[ViewController viewDidLoad] in ViewController.o
  "_kCLDistanceFilterNone", referenced from:
      -[ViewController viewDidLoad] in ViewController.o
ld: symbol(s) not found for architecture i386
collect2: ld returned 1 exit status

I added corelocation.framework into frameworks folder of my project, the project is success on cleaning but failed and give the same three errors on building

Answer 1

You need to import Framework Which you have already done also add the following to your .h file where you are using the CLLocation class such as

#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>

@interface UntitledViewController : UIViewController <CLLocationManagerDelegate> {
    CLLocationManager*      locationManager;
    CLLocation*             locationObject;
}

@end

Hope it helps!!
