I'm experimenting with different ways of displaying a UIView on the screen... I currently have this code, and think it should work to add a green UIView to the app's window, however, it doesn't:
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
NSLog(#"init");
self.backgroundColor = [UIColor greenColor];
self.alpha = 1;
}
return self;
}
+ (SMLoginView *)sharedView{
static dispatch_once_t onceToken;
static SMLoginView *sharedView;
dispatch_once(&onceToken, ^{
sharedView = [[self alloc]initWithFrame:[UIScreen mainScreen].bounds];
});
return sharedView;
}
+ (void)showLoginView{
[[self sharedView]show];
}
- (void)show{
NSLog(#"Show");
[[[[UIApplication sharedApplication] delegate] window] addSubview:self];
}

Insted, u can add it in the called method, because u are adding it in the shared class itself, thats wy it did't appeared.
try this
suppose u are calling this shared method in this "ViewController.m" class
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
SMLoginView *sharedView = [SMLoginView sharedView]; //you always get a shared view handle that view in this class
[self.view addSubview:sharedView]; //add the shared view hear not in the shared class.
}
hope u got this :)
