iOS中怎麼繼承Xib

1. 在子類中寫上此方法

   如－ (instancetype)initWithNibName:(NSString )nibNameOrNil bundle:(NSBundle )nibBundleOrNil {

   if (self = [super initWithNibName:NSStringFromClass([self.superclass class]) bundle:nibBundleOrNil]) {

   <#statements#>

   }

   return self;

   }

2. 在子類中把initWithNibName:把此處改為父類的xib中的名字

   如:- (instancetype)initWithNibName:(NSString )nibNameOrNil bundle:(NSBundle )nibBundleOrNil {

   if (self = [super initWithNibName:@”父類的xib中的名字” bundle:nibBundleOrNil]) {

   }

   return self;

   }
