Custom layout on iOS 7 renders element to high - layout

Question

I have a problem with custom layout on iOS 7. Everything appears too high, i.e. under the navigation bar. On iOS 6 it works like a charm even when compiled with iOS 7 SDK.
Below I post code used to init and layout the view. I don't use Interface Builder and I would prefer not to. Any help appreciated.
- (id)initWithFrame:(CGRect)frame {
self = [super initWithFrame:frame];
if (self) {
self.documentTitle = [UITextField new];
self.documentExtension = [UILabel new];
self.documentTitle.attributedPlaceholder = [[NSAttributedString alloc] initWithString:#"Document title"];
self.documentTitle.font = [UIFont boldSystemFontOfSize:[UIFont systemFontSize] + 1];
self.documentTitle.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
self.documentTitle.borderStyle = UITextBorderStyleRoundedRect;
self.documentTitle.returnKeyType = UIReturnKeyDone;
self.documentTitle.keyboardType = UIKeyboardTypeDefault;
self.documentExtension.text = #".pdf";
self.documentExtension.backgroundColor = [UIColor clearColor];
[self addSubview:self.documentTitle];
[self addSubview:self.documentExtension];
}
return self;
}
- (void)layoutSubviews {
[super layoutSubviews];
UIEdgeInsets padding = UIEdgeInsetsMake(12, 10, 12, 10);
CGRect layoutRect = UIEdgeInsetsInsetRect(self.bounds, padding);
CGPoint p = layoutRect.origin;
CGSize tmpSize;
CGFloat tfSpaceHorizontal = 6;
CGFloat tfSpaceVertical = 6;
CGSize tmpSizeDocumentExtension = [self.documentExtension sizeThatFits:CGSizeMake(CGRectGetWidth(layoutRect), 1000)];
tmpSize = CGSizeMake(
roundf((CGRectGetWidth(layoutRect) - tfSpaceHorizontal - tmpSizeDocumentExtension.width)),
32
);
self.documentTitle.frame = CGRectMake(
p.x, p.y,
tmpSize.width,
tmpSize.height
);
p.x += tmpSize.width + tfSpaceHorizontal;
CGFloat addedHeight = roundf(tmpSize.height/2 - tmpSizeDocumentExtension.height/2);
addedHeight = addedHeight > 0 ? addedHeight : 0;
p.y += addedHeight;
self.documentExtension.frame = CGRectMake(
p.x,
p.y,
tmpSizeDocumentExtension.width,
tmpSizeDocumentExtension.height
);
}

In iOS 7, every view controller uses full-screen layout, so the coordinate system starts under the status bar, so mind that while positioning your views.
This is mentioned in Apple's iOS 7 UI Transitioning Guide.
