Question

I’m trying to pass data around objects using singleton pattern. Here is my code

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;
}

…

The problem is that I get

Incompatible pointer types sending NSString to parameter of type NSStream.

What is wrong here ?
How to pass data to aName ivar ?

Answer 1

In your declaration of aName, did you mistype NSString as NSStream? Stranger things have happened.
