copied!<p>I have an <code>NSArray</code> of objects that wont write to a file. Here is the object header:</p> <pre><code>#import <Foundation/Foundation.h> @interface HSMenuItem : NSObject @property (nonatomic, copy) NSNumber *Id; @property (nonatomic, copy) NSNumber *Meal; @property (nonatomic, copy) NSNumber *DayOfTheWeek; @property (nonatomic, copy) NSString *Body; @property (nonatomic, copy) NSString *StartTime; @property (nonatomic, copy) NSString *EndTime; @property (nonatomic, copy) NSNumber *Seated; - (NSString*) FriendlyMeal; - (NSDate*) Start; - (NSDate*) End; @end </code></pre> <p>I am trying to write the array with <code>- (BOOL)writeToFile:(NSString *)path atomically:(BOOL)flag</code> but it keeps returning <code>NO</code>. Here is the relevant code:</p> <pre><code>NSString* path = [self getPathForCacheFile:identifier]; //identifier is an NSString* argument for this function BOOL b = [arrayToCache writeToFile:path atomically:YES]; MyLog(@"Saved: %@", b ? @"YES":@"NO"); </code></pre> <p>I was searching around and some people were saying it had to do with <code>NSNumber</code>, but <a href="http://developer.apple.com/library/mac/#documentation/General/Conceptual/DevPedia-CocoaCore/PropertyList.html" rel="nofollow">this</a> documentation seems to say that <code>NSNumber</code> is OK to use. What is going on here?</p> <p><strong>Edit</strong></p> <p>I understand whats going on after reading the possible duplicate. This is indeed a duplicate. Please close.</p>
