Add UIViewcontroller with xib with UITableView in UIScrollView - objective-c

Question

I'm trying to add a UIViewController in a UIScrollView, the UIViewController have a UITableView added with Interface Builder, i have connected it to data source and delegate to the File Owner's then i have connect the IBOutlet property with the ActivityView class, when i have do this to add to the UIScrollView:
ActivityView *viewActivity = [[ActivityView alloc] initWithNibName:#"ActivityView" bundle:nil];
[self.scrollView addSubview:viewActivity.view];
but when i open the view the app crash sometime with a BAD_EXC_ACCESS, sometime with a SIGBRT with this error:
[UILabel tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0xd27f8d0
and sometime is this:
[SMPageControl tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0xd68dcb0
and sometime is this:
[NSPathStore2 tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0xd3746b0
i can't understand how ti fix it, if i use the ActivityView alone, without adding it to the UIScrollview, works perfectly, and if i add ActivityView without the connection with the UITableView works, so i think the problem is adding it to the UIScrollView with the UITableView outlet connection, how i can do it?
this is the code of ActivityView:
#import "ActivityView.h"
#interface ActivityView () <UITableViewDelegate, UITableViewDataSource>
#property (weak, nonatomic) IBOutlet UITableView *tableView;
#property (strong, nonatomic) NSMutableArray *activities;
#end
#implementation ActivityView
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [self.activities count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"SimpleTableItem";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
cell.textLabel.text = [self.activities objectAtIndex:indexPath.row];
return cell;
}
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
self.activities = [NSMutableArray array];
[self.activities addObject:#"row"];
}
EDIT: i have tried also to add the UITableView programmatically, without interface builder, and when i set the datasource delegate, crash...everyone can try...crash always...
