问题:

There is a custom view, that consist of class and xib file. I use it as

[[NSBundle mainBundle] loadNibNamed:@"myViewNib" owner:self options:nil];

Question is how to inherit this custom view.

I inherit the myViewClass, but then I can't use the code above to create a instance.I think I'm in the wrong way.

回答1:

One option is not to create MYBaseView itself in the .xib file, but it's subview. This way you will be able to inherit MYBaseView easily.

This is the code should work correctly if you create your view object programmatically or in the Interface Builder:

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

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

- (void)setUp
{
    UIView *view = [[[NSBundle mainBundle] loadNibNamed:NSStringFromClass([self class]) owner:self options:nil] lastObject];
    [self addSubview:view];
}


回答2:

It should be:

myViewClass *newView = [[NSBundle mainBundle] loadNibNamed:@"myViewNib" owner:self options:nil];
