Setting an NSNumber property out of scope
For some or other reason when I call the init method and try and set the property it never seems to work:
//This is where I am setting the value
Hotel *newHotel = [[Hotel alloc]initWithCoordinate: coordinate
hotelId:[NSNumber numberWithInt:1234]];
//This is the implementation of the method I am calling
- (id)initWithCoordinate:(CLLocationCoordinate2D)c hotelId:(NSNumber *)hId
{
s开发者_C百科elf = [super init];
coordinate = c;
hotelId = hId; //When I access this property afterwards its always out of scope
return self;
}
//This is the interface
@interface Hotel : NSObject <MKAnnotation>
{
NSNumber *hotelId;
}
@property (nonatomic, retain) NSNumber *hotelId;
- (id)initWithCoordinate:(CLLocationCoordinate2D)c hotelId:(NSNumber *)hotelId;
@end
Use:
self.hotelId = hId;
so that you use the property's setter.
use
self.hotelId
instead of hotelId
... may be it is just showing out of scope... but the value has assigned properly
Your method descriptions in your interface and implementation don't match.
I changed the type to NSString in desperation and that worked. Please vote to close if you see fit but none of the suggestions worked.
