iPhone Objective C - error: pointer value used where a floating point value was expected
- by Mausimo
I do not understand why i am getting this error. Here is the related code:
Photo.h
#import <CoreData/CoreData.h>
@class Person;
@interface Photo : NSManagedObject
{
}
@property (nonatomic, retain) NSData * imageData;
@property (nonatomic, retain) NSNumber * Latitude;
@property (nonatomic, retain) NSString * ImageName;
@property (nonatomic, retain) NSString * ImagePath;
@property (nonatomic, retain) NSNumber * Longitude;
@property (nonatomic, retain) Person * PhotoToPerson;
@end
Photo.m
#import "Photo.h"
#import "Person.h"
@implementation Photo
@dynamic imageData;
@dynamic Latitude;
@dynamic ImageName;
@dynamic ImagePath;
@dynamic Longitude;
@dynamic PhotoToPerson;
@end
This is a mapViewController.m class i have created. If i run this, the CLLocationDegrees CLLat and CLLong lines:
CLLocationDegrees CLLat = (CLLocationDegrees)photo.Latitude;
CLLocationDegrees CLLong = (CLLocationDegrees)photo.Longitude;
give me the error : pointer value used where a floating point value was expected.
for(int i = 0; i < iPerson; i++)
{
//get the person that corresponds to the row indexPath that is currently being rendered and set the text
Person * person = (Person *)[myArrayPerson objectAtIndex:i];
//get the photos associated with the person
NSArray * PhotoArray = [person.PersonToPhoto allObjects];
int iPhoto = [PhotoArray count];
for(int j = 0; j < iPhoto; j++)
{
//get the first photo (all people will have atleast 1 photo, else they will not exist). Set the image
Photo * photo = (Photo *)[PhotoArray objectAtIndex:j];
if(photo.Latitude != nil && photo.Longitude != nil)
{
MyAnnotation *ann = [[MyAnnotation alloc] init];
ann.title = photo.ImageName;
ann.subtitle = photo.ImageName;
CLLocationCoordinate2D cord;
CLLocationDegrees CLLat = (CLLocationDegrees)photo.Latitude;
CLLocationDegrees CLLong = (CLLocationDegrees)photo.Longitude;
cord.latitude = CLLat;
cord.longitude = CLLong;
ann.coordinate = cord;
[mkMapView addAnnotation:ann];
}
}
}
