Populate UIPickerView with images - ios

Question

I'm trying to populate a UIPickerView with images.
Here is where i create programmatically the PickerView and i fill a NSMutableArray with 35 images called 1.png, 2.png ..., 35.png
#interface ShowImagesPVC () <UIPickerViewDataSource, UIPickerViewDelegate>
#property (strong, nonatomic) NSMutableArray *arrayOfImages;
#end
- (void)viewDidLoad
{
[super viewDidLoad];
for(int i = 1; i < 36; i++){
NSString *tmpString = [NSString stringWithFormat:#"%d.png",i];
[_arrayOfImages addObject:[[UIImageView alloc]initWithImage:[UIImage imageNamed:tmpString]]];
}
UIPickerView *myPickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(-5, 0, 315, 200)];
myPickerView.delegate = self;
myPickerView.dataSource = self;
myPickerView.showsSelectionIndicator = YES;
[self.view addSubview:myPickerView];
}
now i've implemented these methods
- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view
{
return [_arrayOfImages objectAtIndex:row];
}
- (NSInteger)numberOfComponentsInPickerView: (UIPickerView *)pickerView
{
return 1;
}
-(NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
{
return _arrayOfImages.count;
}
The problem is that the UIPicker is created but it's empty, so i tried to NSLog the method - (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view and it seems it's never called.
Any idea why?

try this
- (void)viewDidLoad
{
[super viewDidLoad];
_arrayOfImages = [NSMutableArray array];
for(int i = 1; i < 36; i++){
NSString *tmpString = [NSString stringWithFormat:#"%d.png",i];
[_arrayOfImages addObject:[[UIImageView alloc]initWithImage:[UIImage imageNamed:tmpString]]];
}
UIPickerView *myPickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(-5, 0, 315, 200)];
myPickerView.delegate = self;
myPickerView.dataSource = self;
myPickerView.showsSelectionIndicator = YES;
[self.view addSubview:myPickerView];
}
