最简单创建bundle文件：创建一个文件夹更改文件夹名称为:xxx.bundle

向里面添加东西直接显示包内容复制进去就行了

bundle里面一般存一些资源文件比如图片，音乐，plist等当然也可以存nib文件，类文件里面也有相应的方法打开

得到bundle路径：

NSString * bundlePath = [[ NSBundle mainBundle] pathForResource: @ "MyBundle"ofType :@ "bundle"];

获取bundle里面的文件：

- (nullable NSString *)pathForResource:(nullable NSString *)name ofType:(nullable NSString *)ext;

例子

1.加载nib

NSString * bundlePath = [[ NSBundle mainBundle] pathForResource: @ "MyBundle"ofType :@ "bundle"];NSBundle *resourceBundle = [NSBundle bundleWithPath:bundlePath];UIViewController *vc = [[UIViewController alloc] initWithNibName:@"vc_name"bundle:resourceBundle];

 2.获取图片

UIImageView *imgView=[[UIImageView alloc] initWithFrame:CGRectMake(50, 50, 50,50)];UIImage *image = [UIImage imageNamed:@"MyBundle.bundle/img_collect_success"];[imgView setImage:image];

 or

UIImageView *imgView=[[UIImageView alloc] initWithFrame:CGRectMake(50, 50, 50,50)];NSString *imgPath= [bundlePath stringByAppendingPathComponent:@"img_collect_success.png"];UIImage *image_1=[UIImage imageWithContentsOfFile:imgPath];[imgView setImage:image_1];
