title: UIPicker and UIActionsheet no longer working iOS7
body: <p>Hi My UI Picker no longer works on iOS7, it pops up but it is blank. Only happened on iOS7.</p>
  
  <pre><code>//picker
  -(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component{
  animationsLabel.text = [optionsArray objectAtIndex:[picker selectedRowInComponent:0]];
  
  if (pickerView==animationsPicker) {
      animationsLabel.text = [optionsArray objectAtIndex:[animationsPicker selectedRowInComponent:0]];
  }
  
  }
  -(NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView{
      return 1;
  }
  
  -(NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component{
      return [optionsArray count];
  }
  
  -(NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component{
     return [optionsArray objectAtIndex:row];
     NSLog(@"title options array %lu",(unsigned long)optionsArray.count);
  }
  </code></pre>
  
  <p>And the action:</p>
  
  <pre><code>-(IBAction)animationActionSheet:(id)sender {
  
  UIActionSheet *selectPopup = [[UIActionSheet alloc] initWithTitle:@"\n\n\n\n\n\n\n\n"
                                                          delegate:nil
                                                 cancelButtonTitle:nil
                                            destructiveButtonTitle:nil
                                                 otherButtonTitles:nil];
  
  [selectPopup showInView:self.view];
  
  optionsArray = [[NSMutableArray alloc] initWithObjects:@"1",@"2",@"3",@"4",@"6",@"5",@"7",@"8",@"9", nil];
  
  // Create picker
  animationsPicker = [[UIPickerView alloc] initWithFrame:CGRectMake(10, 160, 320, 100)];
  animationsPicker.showsSelectionIndicator = YES;
  [self.view addSubview:animationsPicker];
  animationsPicker.delegate = self;
  animationsPicker.dataSource = self;
  [selectPopup addSubview:animationsPicker];
  
  // Animate picker opening
  [UIView beginAnimations:nil context:nil];
  [selectPopup setBounds:CGRectMake(0, 0, 320, 485)];
  [UIView commitAnimations];
  }
  </code></pre>
  
  <p>This is what I have tried so far. There was never a problem displaying the picker in the an Action sheet before, but now it is blank. Im wondering did anyone else come across this problem, or can you see any errors? I printed everything to do with the picker.</p>
