NSCalendar: Problema al obtener semanas en un mes

Estoy creando un control de calendario de clases ...NSCalendar: Problema al obtener semanas en un mes

Una cosa que necesito saber es cuántas semanas hay en un mes ...

Así NSCalendarrangeOfUnit:inUnit:forDate parece ser exactamente lo que necesito ...

Excepto estoy notando algo que parece fuera y no puedo averiguar por qué esto está ocurriendo ...

El siguiente código ...

NSCalendar *calendar = [NSCalendar currentCalendar]; 

NSDateComponents *dateComponents = [[NSDateComponents alloc] init]; 
[dateComponents setYear: 2010]; 
[dateComponents setDay: 1]; 

for (int x=1; x<=12; x++) 
{ 
    [dateComponents setMonth: x]; 

    NSDate *date = [calendar dateFromComponents:dateComponents]; 
    NSLog(@"Date: %@", date); 

    NSRange range = [calendar rangeOfUnit: NSWeekCalendarUnit 
            inUnit: NSMonthCalendarUnit 
            forDate:date]; 

    NSLog(@"%d Weeks in Month %d", range.length, [dateComponents month]); 

}

está devolviendo los siguientes mensajes de depuración ...

I Cant averiguar por qué me sale 52 semanas en el mes 12.

Alguna pista?

Editar en 3/20/2010:

En vista de que no pude usar rangeOfUnit:inUnit:forDate para calcular el número de semanas en un mes. Decidí encontrar una forma diferente de calcular el mismo valor.

Pensé que debería hacer esto de una manera no gregoriana, por lo que intenté comenzar con la cantidad de días en una semana, pero obtuve el resultado de 28 días en una semana. Así que comencé a escribir más código para descubrir por qué ...

Quería asegurarme de que el tipo de NSCalendar con el que estaba jugando fuera en realidad lo que se suponía que debía obtener ... Y eso me llevó a encontrar algunas diferencias ...

NSCalendar *currentCalendar = [NSCalendar currentCalendar]; 

NSLog(@"Calendar with 'currentCalendar' Identifier: %@", 
     [currentCalendar calendarIdentifier]); 

NSCalendar *calendarWithIdentifier = [[[NSCalendar alloc] initWithCalendarIdentifier: NSGregorianCalendar] autorelease]; 

NSLog(@"Calendar created with identifier Identifier: %@", 
     [calendarWithIdentifier calendarIdentifier]); 

NSDate *now = [[NSDate alloc] init]; 

NSDateComponents *currentMonth = [currentCalendar components: NSMonthCalendarUnit | NSYearCalendarUnit 
                fromDate: now]; 

NSDate *currentMonthDate = [currentCalendar dateFromComponents: currentMonth]; 

NSRange daysInWeekRange = [currentCalendar rangeOfUnit: NSDayCalendarUnit 
               inUnit: NSWeekCalendarUnit 
               forDate: currentMonthDate]; 

NSLog(@"CurrentCalendar: Length:%u Location:%u", daysInWeekRange.length, daysInWeekRange.location); 

currentMonth = [calendarWithIdentifier components: NSMonthCalendarUnit | NSYearCalendarUnit 
             fromDate: now]; 

currentMonthDate = [calendarWithIdentifier dateFromComponents: currentMonth]; 

daysInWeekRange = [calendarWithIdentifier rangeOfUnit: NSDayCalendarUnit 
               inUnit: NSWeekCalendarUnit 
               forDate: currentMonthDate]; 

NSLog(@"GregorianCalendar: Length:%u Location:%u", daysInWeekRange.length, daysInWeekRange.location);

y eso me los siguientes resultados del registro tiene ...

Tomar dirección de la experiencia de @ CarlNorum, compilé el fragmento de código como una aplicación Cocoa 10.6, y Obtuve lo siguiente ...

2010-03-20 21:05:35.636 ScrapCocoa[52238:a0f] Calendar with 'currentCalendar' Identifier: gregorian 
2010-03-20 21:05:35.636 ScrapCocoa[52238:a0f] Calendar created with identifier Identifier: gregorian

2010-03-20 21:05:35.638 ScrapCocoa[52238:a0f] GregorianCalendar: Length:7 Location:1

vi esperanza en que la creación de una instancia NSCalendar explícitamente como un calendario gregoriano conduciría a mejores resultados en mi problema original ... Así que modifica el código original de

NSCalendar *currentCalendar = [NSCalendar currentCalendar]; 

NSLog(@"Calendar with 'currentCalendar' Identifier: %@", 
     [currentCalendar calendarIdentifier]); 

NSCalendar *calendarWithIdentifier = [[[NSCalendar alloc] initWithCalendarIdentifier: NSGregorianCalendar] autorelease]; 

NSLog(@"Calendar created with identifier Identifier: %@", 
     [calendarWithIdentifier calendarIdentifier]); 

NSDateComponents *dateComponents = [[[NSDateComponents alloc] init] autorelease]; 
[dateComponents setYear: 2010]; 
[dateComponents setDay: 1]; 

for (int x=1; x<=12; x++) 
{ 
    [dateComponents setMonth: x]; 

    NSDate *date = [currentCalendar dateFromComponents: dateComponents]; 
    NSRange range = [currentCalendar rangeOfUnit: NSWeekCalendarUnit 
              inUnit: NSMonthCalendarUnit 
             forDate: date]; 

    NSLog(@"CurrentCalendar Date: %@", date); 
    NSLog(@"CurrentCalendar: %d Weeks in Month %d", range.length, [dateComponents month]); 

    date = [calendarWithIdentifier dateFromComponents: dateComponents]; 

    range = [calendarWithIdentifier rangeOfUnit: NSWeekCalendarUnit 
             inUnit: NSMonthCalendarUnit 
             forDate: date]; 

    NSLog(@"GregorianCalendar Date: %@", date); 
    NSLog(@"GregorianCalendar: %d Weeks in Month %d", range.length, [dateComponents month]); 

}

Desafortunadamente el uso de un calendario creado de esa manera no devolvió un resultado diferente.

Acabo de hacer un nuevo proyecto y ejecuté ese código y se comporta como se esperaba. ¿Es ese el código exacto que estás viendo fallido? –

¿Obtendrá 52 semanas en diciembre? –

@AngrySpade, no obtengo '5 semanas en el mes 12'. –

Intenté este código con el SDK 10.6 y parece que funciona.

Lo probé con el iPhone SDK y obtengo el mismo resultado que usted. No está claro si el SDK de iPhone está produciendo los valores correctos para muchos de los otros meses también. Estoy de acuerdo, por ejemplo, con la respuesta 10.6 SDK que Jan. tiene 6 semanas.

No veo nada obviamente mal con su código.

Podría sugerir en primer lugar dirigirse a http://bugreport.apple.com y enviar un error.

También puede dirigirse a los foros de desarrolladores privados de Apple (http://developer.apple.com/devforums/) e intentar preguntar allí.

Por supuesto, también puede enviar un incidente de soporte técnico a Apple ([email protected] - http://developer.apple.com/programs/adcbenefits/) ... si no tiene ninguno en su cuenta de ADC, creo que Apple estará encantado de venderle uno y puede hablar directamente con un ingeniero de Apple sobre este problema.

que pregunté en el foro ... Veremos si surge algo. https://devforums.apple.com/thread/41850 –

He recibido más confirmación de que este es un error ... Presenté un error de apple ... https://bugreport.apple.com/cgi-bin/ WebObjects/RadarWeb.woa/110/wo/bgn2sV1PSwrS42bBbWs2uM/10.79.28.0.9 –

@AngrySpade: Esa URL no significa nada fuera de esa sesión. El número de error sería mucho más útil. –
