iphone - 这是正确的代码重新存储管理-对于基本的自定义类

Question

我是否需要在此处添加/修改任何内容以重新自定义类的内存管理？ (例如，需要任何“发布”行，不需要dealloc方法吗？)

#import <Foundation/Foundation.h>
@interface TimelineItem : NSObject {
    NSDate *_startDate;
    BOOL _working;
    BOOL _coreWeekend;
}
@property (nonatomic, retain) NSDate *startDate;
@property (nonatomic) BOOL working;
@property (nonatomic) BOOL coreWeekend;
- (id)initWithStartDate:(NSDate*)startDate Working:(BOOL)working CoreWeekend:(BOOL)coreWeekend;
@end



#import "TimelineItem.h"
@implementation TimelineItem
@synthesize startDate = _startDate;
@synthesize working = _working;
@synthesize coreWeekend = _coreWeekend;
- (id)initWithStartDate:(NSDate*)startDate Working:(BOOL)working CoreWeekend:(BOOL)coreWeekend {
    if (self == [super init])
    {
        // Initialization
        self.startDate = startDate;
        self.working = working;
        self.coreWeekend = coreWeekend;
    }
    return self;
}
@end

Answer 1

不它不是。您已经通过将属性声明为retained来对startDate参数进行(retain)。这意味着您有责任在某个时间对其进行releasing编码。您可以通过添加以下内容来解决此问题:

- (void)dealloc {
  [_startDate release];
  [super dealloc];
}

另外，您不应该在初始化方法名称中大写“Working”和“CoreWeekend”。它们应该分别是“正在工作”和“coreWeekend”。
