iphone - 无法使用@interface 将对象添加到 NSMutableArray

Question

有人可以告诉我我做错了什么，应用程序（iphone ios5）在执行“addStatus：statusObj”时会崩溃吗？

id<Statuses> statusObjects;
statusObjects = [Status singleton];

id<Statuses> statusMessagesObjects;
statusMessagesObjects = [[Status singleton] copy];
StatusObj *statusObj = [[StatusObj alloc] init];
statusObj.date = [NSDate date];
[statusMessagesObjects addStatus:statusObj];
StatusObj *tmpObj = [statusMessagesObjects getStatusAtIndex:0];
DebugLog(@"-- debug -- %@", tmpObj.date);

---------------------------------------头文件---------- -------------------------

@interface Status : NSObject <Statuses, NSCopying>
{
    NSMutableArray* status;
    NSString* path;
}

+ (id) singleton;

@property (copy) NSString* path;

- (void) addStatus:(StatusObj*)statusObj;
- (void) deleteStatusAtIndex:(NSUInteger)index;
- (StatusObj*) getStatusAtIndex:(NSUInteger)index;
- (int) count;
- (void)save;
- (id)copyWithZone:(NSZone *)zone; 

@end


@protocol Statuses <NSObject>

@required
- (void) addStatus:(StatusObj*)statusObj;
- (void)deleteStatus:(StatusObj *)statusObj;
- (void) deleteStatusAtIndex:(NSUInteger)index;
- (void)deleteAllStatuses;
- (StatusObj*) getStatusAtIndex:(NSUInteger)index;
- (int) count;
- (void)save;

@optional
- (void)moveStatus:(StatusObj *)statusObj toIndex:(NSUInteger)newIndex;

@end

您的代码看起来很奇怪，而且您的命名约定非常规，为什么要复制您的 Singleton？

我已经编辑了你的可能会有所帮助，但如果你发布你的实现会很有帮助。

id<Statuses> status;
status = [Status singleton];

StatusObj *statusObj = [StatusObj new];
statusObj.date = [NSDate date];

[status addStatus: statusObj];

StatusObj *tmpObj = [status getStatusAtIndex:0];
DebugLog(@"-- debug -- %@", tmpObj.date);
