IOS UILabel shadow generates weird upper shadow

Question

I'm trying to apply a shadow to a UILabel, but I get an ugly upper shadow on the font.

As you can see the shadow is already far away from the font, but I'm getting this shadowed upper thingy... The font should be pure white.

Any idea? I could put another UILabel over it, but I think it's not the cleanest solution...

float width = 500.0f;
    UIShadowLabel *label = [[UIShadowLabel alloc] initWithFrame:CGRectMake((self.view.bounds.size.width * 0.5) - (width * 0.5), 150.0, width, 100.0) ];
    label.backgroundColor = [UIColor clearColor]; 
    label.shadowColor = UIColorFromRGB(0xb1b0b0);
    label.shadowRadius = 3.0f;
    label.shadowOffset = CGSizeMake(15.0f, 15.0f);
    label.textAlignment =  UITextAlignmentCenter;
    label.textColor = [UIColor whiteColor];
    label.font = [UIFont fontWithName:@"Arial" size:(100.0)];
    [self.view addSubview:label];
    label.text = @"am";

Use below code as per your need

[self.yourView.layer setShadowColor:[UIColor blackColor].CGColor];
[self.yourView.layer setShadowOpacity:0.8];
[self.yourView.layer setShadowRadius:3.0];
[self.yourView.layer setShadowOffset:CGSizeMake(2.0, 2.0)];
