Question

I have a mapview where i update my currentlocation with CoreLocation, but I also have checks which uses userLocation.

I still haven’t found an alternative in fixing my problem
But for some reason I can’t use userLocationVisible to hide the blue dot.

When I enter my MapView I start the locationManager, but before I have updated my location, the blue dot appears and my pin doesn’t show up.

I’ve tried to use a custom MKAnnotation and init the coordinates with the newLocation from DidUpdateToLocation. But when I run this I get:

-[CustomPlacemark setCoordinate:]: unrecognized selector sent to instance 0x1de6c0

this is my CustomPlacemark:

#import <Foundation/Foundation.h>
#import <MapKit/MapKit.h>

@interface CustomPlacemark : NSObject<MKAnnotation> {
    CLLocationCoordinate2D coordinate;  
    NSString *title;
    NSString *subtitle;
}
@property (nonatomic, readonly) CLLocationCoordinate2D coordinate;
@property (nonatomic, retain) NSString *title;
@property (nonatomic, retain) NSString *subtitle;

-(id)initWithCoordinate:(CLLocationCoordinate2D) coordinate;
- (NSString *)subtitle;
- (NSString *)title;
@end

#import "CustomPlacemark.h"

@implementation CustomPlacemark
@synthesize coordinate;
@synthesize title, subtitle;

-(id)initWithCoordinate:(CLLocationCoordinate2D) c{
    self=[super init];
    if (self!=nil) {
        coordinate=c;
    }
    return self;
}

-(NSString*)title{
    return title;
}

-(NSString*)subtitle{
    return subtitle;
}

-(void) dealloc
{
    [title release]; title = nil;
    [subtitle release]; subtitle = nil;
    [super dealloc];
}
@end

Can someone also tell me why I can’t use UserLocationVisible??

Answer 1

cordinate is read only property for customplacemark class . so u can not set cordinate property. to set cordinate property make it read and write.

change line@property (nonatomic, readonly) CLLocationCoordinate2D coordinate;

To @property (nonatomic, readwrite) CLLocationCoordinate2D coordinate;
