Can anyone tell me why logging [self.giftees count] keeps returning 0 even though I'm adding objects to it?
header:
#import <UIKit/UIKit.h>
@interface Test2AppDelegate : NSObject <UIApplicati开发者_C百科onDelegate>
{
UIWindow *window;
NSMutableArray *giftees;
}
@property (nonatomic, retain) UIWindow *window;
@property (nonatomic, retain) NSMutableArray *giftees;
@end
called from didFinishLaunchingWithOptions:
- (void)bootstrapGiftees
{
NSArray *gifteeNames = [NSArray arrayWithObjects:@"Jesse",,nil];
for (NSString *gifteeName in gifteeNames)
{
GifteeModel *g = [[GifteeModel alloc] init];
g.name = gifteeName;
[self.giftees addObject:g];
NSLog(@"giftees count = %d", [self.giftees count]);
[g release];
}
}
Is "giftees" initialized? If it is nil, [giftees count] will return 0 as well
Because you most probably never initialized the giftees array at all, so it is still nil when that code runs.
