This is demo code to show Your Custom Xib UIView(w/ or w/o autolayout) on another Xib or Storyboard View Controller
The most important UIView base code is inside BaseView or here.
- (void)xibSetup {
#if !TARGET_INTERFACE_BUILDER
NSBundle *bundle = [NSBundle mainBundle];
#else
NSBundle *bundle = [NSBundle bundleForClass:[self class]];
#endif
// change nib named string if your xib name not the same as class
UIView *view = [[bundle loadNibNamed:NSStringFromClass([self class]) owner:self options:nil] firstObject];
view.frame = self.layer.bounds;
view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
[self addSubview:view];
}Because showing Xib on another Xib you have to implement initWithFrame with some view setup function. And be aware of the TARGET_INTERFACE_BUILDER, it's a must have bundle init type check method.
