UIButton outside of UIView (xib) frame

Question

I have a custom UIView XIB that gets loaded onto my ViewController and the frame is adjusted to be collapsed before added to subview. The UIButton tied to my XIB is showing when the frame is smaller than the button location. How can I hide and show my UIButton as the frame is expanding/collapsing? My XIB is not using AutoLayout.

ViewController.m

self.greenView = [[[NSBundle mainBundle] loadNibNamed:@"Green" owner:self options:nil] objectAtIndex:0];
[self.navigationController.view addSubview:self.greenView];

GreenView.h

@interface GreenView : UIView
@property (weak, nonatomic) IBOutlet UIView *expandView;
@property (nonatomic, getter = isExpanded) BOOL expand;
@property (weak, nonatomic) IBOutlet UIButton *testButton;
- (IBAction)testButtonTapped:(id)sender;
@end

GreenView.m

@interface GreenView()
@property (nonatomic) UITapGestureRecognizer *tapGesture;
@end

@implementation GreenView
- (void)awakeFromNib {
    CGRect frame = self.frame;
    frame.size.height = self.expandView.frame.size.height;
    frame.origin.y = 200;
    self.frame = frame;
    self.expand = NO;
    [self.expandView addGestureRecognizer:self.tapGesture];
}

- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        // Initialization code
    }
    return self;
}

- (UITapGestureRecognizer *)tapGesture {
    if (!_tapGesture) {
        _tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapClicked:)];
    }
    return _tapGesture;
}

- (void)tapClicked:(UIGestureRecognizer *)recognizer {
    CGRect frame = self.frame;
    self.expand = !self.expand;
    frame.size.height = self.expand ? gvExpandedHeight : gvCollapsedHeight;

    [UIView animateWithDuration:0.5 animations:^{
        self.frame = frame;
    } completion:^(BOOL finished) {
        NSLog(@"Frame after animation: %@", NSStringFromCGRect(self.frame));
    }];
}

- (IBAction)testButtonTapped:(id)sender {
    NSLog(@"Test button tapped");
}
@end

Answer 1

If I understood you just want to clip it, if the button is outside to the view bounds. In -awakeFromNib add:

self.clipsToBounds = YES;

Using this property you are telling the view to cut everything that is not inside its bounds, views caw draw subviews even if they are place outside. Is a little expensive by means of performance, if you use it a lot or during heavy animations.
One way around could be hide it while the view is collapsed.

Answer 2

You change the frame to frame.origin.y = 200;

I think you have to set the UIButton constraint relative to your GreenView in you nib file
