initWithCoder is returning 0 values for frame property

Question

I have sub-classed uiscrollview and used initWithCoder to prepare my uiscrollview with all the subviews. I have used below code to set it up:

- (id)initWithCoder:(NSCoder *)aDecoder {
    if ((self = [super initWithCoder:aDecoder])) {

    NSLog(@"%f", self.frame.size.height);

    self.contentSize = CGSizeMake(5000, self.frame.size.height);

    labelContainerView = [[UIView alloc] init];
    labelContainerView.frame = CGRectMake(0, 0, self.contentSize.width, self.contentSize.height/2);
    labelContainerView.backgroundColor = [UIColor yellowColor];
    [self addSubview:labelContainerView];
}

But this keeps failing because the self.frame property always return 0 values. Its super important for me to use self.frame property because I want to use storyboard to do any height adjustments for the frame of the scrollview.

I have tried the same thing using xib files instead of using the storyboard and it works fine. But in my project I dont want to use xib files.

It'll be really great if anyone can explain me why I get 0 values in initWithCoder: method when I use storyboard? and if using storyboard how to achieve this?

PS: I notice layoutSubviews method return correct frame information but I cannot create my subviews here since it get called for each frame change (when I scroll)

Answer 1

Are you using Autolayout in your Storyboard?

If you are really not taking advantage of it, you can disable it and your -initWithCoder: method will return your frame again.

If you do need Autolayout, try the following:

-(void)awakeFromNib
{
    [super awakeFromNib];

    [self setNeedsLayout];
    [self layoutIfNeeded];

    // self.frame will now return something :)
}
