iOS中怎么继承Xib

在子类中写上此方法  如－ (instancetype)initWithNibName:(NSString )nibNameOrNil bundle:(NSBundle )nibBundleOrNil {  if (self = [super initWithNibName:NSStringFromClass([self.superclass class]) bundle:nibBundleOrNil]) {  <#statements#>  }  return self;  }

在子类中把initWithNibName:把此处改为父类的xib中的名字  如:- (instancetype)initWithNibName:(NSString )nibNameOrNil bundle:(NSBundle )nibBundleOrNil {  if (self = [super initWithNibName:@”父类的xib中的名字” bundle:nibBundleOrNil]) {

}  return self;  }
