我正在尝试使用单例模式在对象周围传递数据。这是我的代码

SearchData.m

@implementation SearchData
@synthesize theName = _theName;

-(id)init
{
    if(self = [super init])
    {
        _theName = @"Default";
    }
    return  self;
}

static SearchData *sharedSingleton = NULL;

+(SearchData *)sharedSearchData
{
    @synchronized(self)
    {
        if (sharedSingleton == NULL)
        {
            sharedSingleton = [[self alloc]init];
        }
        return sharedSingleton;
    }
}
@end


FirstView.m

...

-(id)init
{
    if (self = [super init])
    {
        SearchData *data = [SearchData sharedSearchData];
        self.aName = [data theName];
    }
    return self;
}


...

问题是我得到了

Incompatible pointer types sending NSString to parameter of type NSStream.

这是怎么了?
如何将数据传递给aName ivar?

最佳答案

aName声明中,您是否将NSString键入为NSStream?发生了奇怪的事情。
