Question

I’ve a NSMutableArray and I’m assigning object to it like [appDelegate.array addObject:Obj]; when i call NSLog(@"appdelegate.array %@ ", [appdelegate.array description]) ; I’m getting like this in consol

(
    "<Item: 0x6c8b650; frame = (0 0; 0 0); transform = [0, 0, 0, 0, 0, 0]; alpha = 0; opaque = NO; layer = (null)>",
    "<Item: 0x6b825c0; frame = (0 0; 0 0); transform = [0, 0, 0, 0, 0, 0]; alpha = 0; opaque = NO; layer = (null)>",
    "<Item: 0x6b82ad0; frame = (0 0; 0 0); transform = [0, 0, 0, 0, 0, 0]; alpha = 0; opaque = NO; layer = (null)>"
)

Can any one suggest me to correct format to add objects and why array contains frame = (0 0; 0 0); transform = [0, 0, 0, 0, 0, 0]; alpha = 0; opaque = NO; layer = (null) ??

+ (void) getInitialCurrencyToDisplay:(NSString *)dbPath{


    AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];

    if (sqlite3_open([dbPath UTF8String], &database) == SQLITE_OK) {

        const char *sql = "select  c_name,C_Id from Currency";
        sqlite3_stmt *selectstmt;
        if(sqlite3_prepare_v2(database, sql, -1, &selectstmt, NULL) == SQLITE_OK) {

            while(sqlite3_step(selectstmt) == SQLITE_ROW) {
                NSInteger primaryKey = sqlite3_column_int(selectstmt, 1);

                Currency *Obj = [[Currency alloc]initWithPrimaryKey:primaryKey];
                Obj.C_Name = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectstmt, 0)];
                Obj.address=[NSString stringWithUTF8String:(char *)sqlite3_column_text(selectstmt, 1)];

                NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
                NSString *documentsDir = [documentPaths objectAtIndex:0];
                NSLog(@"%@", documentsDir);
                NSString *pngFilePath = [NSString stringWithFormat:@"%@/%@.png",documentsDir, Obj.C_Name];

                Obj.C_Image = [[UIImage alloc] initWithContentsOfFile:pngFilePath];


           Obj.isDirty = NO;
                [appDelegate.array addObject:Obj];

            }
        }

I used above code to get data from Database
Thanks in Advance

Check the parent class of your Currency class. The parent class should be NSObject and not UIView or similar.

And please have a look at the Objective-C naming conventions. Only classes should start with a capital letter.
