I am trying to run this program on iPhone 3GS with iOS 5. Program works fine on simulator but doesn't work on device. No error but locationManager:didUpdateToLocation:fromLocation delegate method doesn't get called when run on the device.
I just want to print location after every 30 seconds.
I just want to print location after every 30 seconds.
Code:
int main(int argc, char *argv[])
{
iLocation *loc = [[iLocation alloc] init];
NSDate *now = [[NSDate alloc] init];
NSTimer *timer = [[NSTimer alloc] initWithFireDate:now
interval:30
target:loc
selector:@selector(start)
userInfo:nil
repeats:YES];
NSRunLoop *runLoop = [NSRunLoop currentRunLoop];
[runLoop addTimer:timer forMode:NSDefaultRunLoopMode];
[runLoop run];
}
@interface iLocation : NSObject <CLLocationManagerDelegate>
@property (strong, nonatomic) CLLocationManager *locationManager;
@property (strong, nonatomic) NSTimer *timer;
-(void) start;
@end
@implementation iLocation
@synthesize locationManager;
@synthesize timer;
-(void) start
{
NSLog(@"Enter in start");
locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
[locationManager startUpdatingLocation];
NSLog(@"Exit from start");
}
