Permanet view on window objective c - ios

Question

I need to add a UIView to the main window, the UIView consists in a view with some buttons.
The problem is, the buttons i put inside that view, is not responding for the touch events,
like it have some view in front of it.
That view need to be a singleton class, cause i need to respond the touchevent in any class.
Heres the code for the UIView :
+ (MenuBarView *)sharedMenuBar
{
static MenuBarView *sharedSingleton;
#synchronized(self) {
if (!sharedSingleton) sharedSingleton = [[MenuBarView alloc] init];
return sharedSingleton;
}
}
-(id)init
{
self = [super init];
if(self)
{
self.userInteractionEnabled = YES;
backgroundBarImage = [UIImage imageNamed:#"Barra.png"];
UIImageView * backgroundBar = [[UIImageView alloc]initWithImage:backgroundBarImage];
backgroundBar.contentMode = UIViewContentModeCenter;
backgroundBar.backgroundColor = [UIColor clearColor];
[backgroundBar setFrame:CGRectMake(0, 0, backgroundBarImage.size.width, backgroundBarImage.size.height)];
[self addSubview:backgroundBar];
UIButton * rootBTN = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[rootBTN setFrame:CGRectMake(0, 8, 100, 40)];
[rootBTN addTarget:self action:#selector(selectedBarButton:) forControlEvents:UIControlEventTouchUpInside];
[self addSubview:rootBTN];
UIImage * localizacaoIMG = [UIImage imageNamed:#"Localizador"];
UIImageView * localizacaoView = [[UIImageView alloc]initWithImage:localizacaoIMG];
localizacaoView.contentMode = UIViewContentModeScaleAspectFill;
[localizacaoView setFrame:CGRectMake(backgroundBar.frame.origin.x+130, 8, localizacaoIMG.size.width, localizacaoIMG.size.height)];
[backgroundBar addSubview:localizacaoView];
UIButton * localizacaoBTN = [UIButton buttonWithType:UIButtonTypeCustom];
[localizacaoBTN setFrame:CGRectMake(backgroundBar.frame.origin.x+110, 8, 60, 40)];
localizacaoBTN.tag = 1;
[self addSubview:localizacaoBTN];
}
return self;
}
//The event handling method
-(void)selectedBarButton:(UIButton *)sender
{
NSLog(#"OK");
[self.delegate selectedMenuBar:sender.tag];
}
and heres the implementation on the AppDelegate :
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.viewController = [[InitialViewController alloc] init];
self.navController = [[EzMallNavViewController alloc]initWithRootViewController:self.viewController];
self.window.rootViewController = self.navController;
[self.window makeKeyAndVisible];
if(IS_IPOD)
{
[[MenuBarView sharedMenuBar]setFrame:CGRectMake(0, self.window.frame.size.height-51, [MenuBarView sharedMenuBar].frame.size.width, [MenuBarView sharedMenuBar].frame.size.height)];
}
else
{
[[MenuBarView sharedMenuBar]setFrame:CGRectMake(0, self.window.frame.size.height, [MenuBarView sharedMenuBar].frame.size.width, [MenuBarView sharedMenuBar].frame.size.height)];
}
[MenuBarView sharedMenuBar].delegate = self;
[self.window addSubview:[MenuBarView sharedMenuBar]];
return YES;
}
#pragma mark MenuBarDelegateMethods
-(void)selectedMenuBar:(int) tag
{
NSLog(#"Here");
}

Answer 1

It looks like your menu view has a zero size frame so no touches are detected. The buttons appear on screen because the menu view isn't set to clip drawing to its bounds.

Answer 2

Try to set different color for different views and analyze the view hierarchy ,it might be possible that you have added the view in wrong order .
