Проблема с подпредставлениями, но она может быть связана с AppDelegate в отношении размещения UIPickerView в myView по сравнению с self.view?
Спасибо
[self.view addSubview:pickerView]; <-- works ok
//[myView addSubview:pickerView];<-- fails, can't get dial movement or response
AppDelegate.h
#import <UIKit/UIKit.h>
@class PickerViewController;
@interface PickerViewAppDelegate : NSObject <UIApplicationDelegate> {
UIWindow *window;
PickerViewController *pvController;
}
@property (nonatomic, retain) IBOutlet UIWindow *window;
@end

@implementation PickerViewAppDelegate
@synthesize window;
- (void)applicationDidFinishLaunching:(UIApplication *)application {
pvController = [[PickerViewController alloc] initWithNibName:@"PickerView" bundle:[NSBundle mainBundle]];
[window addSubview:pvController.view];
// Override point for customization after application launch
[window makeKeyAndVisible];
}
- (void)dealloc {
[pvController release];
[window release];
[super dealloc];
}

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {

UIView *myView = [[UIView alloc] initWithFrame:CGRectMake(0, 100, 100, 100)];
[myView setBackgroundColor:[UIColor blueColor]];
[self.view addSubview:myView];
UIPickerView *pickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(0.0, 0.0, 100.0, 100.0)];
pickerView.delegate = self;
pickerView.showsSelectionIndicator = YES;
arrayColors = [[NSMutableArray alloc] init];
for (int i=0; i<60; i++) {
[arrayColors addObject:[NSString stringWithFormat:@"%d", i]];
}
//[self.view addSubview:pickerView]; // <-- works
[myView addSubview:pickerView]; // <-- this fails.. this is what I need for multiple views
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning]; // Releases the view if it doesn't have a superview
// Release anything that's not essential, such as cached data
}
- (void)dealloc {
