Which init method for UIView will be called when using drag and drop in xib file

here is the custom collection view,and below label is the (rating view i design).
enter image description here 

    - (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {

        [self initGrayStarView];

        [self initYellowStarView];

        [self initRatingLabel];
    }
    return self;
}

but i find that it every time the rating view didn't appear(image view and label did). then i found it's because that i didn't call the init method for rating view,so it's nil ,but why?
this is the init method.

but it never call it ,it only call the layoutSubview method.

Solution

  • Consider this sort of pattern...

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

-(id)initWithCoder:(NSCoder *)aCoder {
    if (self = [super initWithCoder:aCoder]) {
        [self _setup];
    }
    return self;
}

-(void)_setup {
    blah;
    blah;
    blah;
}

    Try to "know what is happening" but that will get you through if you're just getting started.
