1.首先，我们需要把用到的图片放到一个文件夹下面,然后更改这个文件夹的名字，在原来的文件名字后面添加.bundle，添加完毕之后，会出现一个弹出框，点击使用.bundel的按钮，

点击之后，会生成一个带有.bundle的文件

2.图片获得bundle中的资源
UIImageView *imgView=[[UIImageView alloc] initWithFrame:CGRectMake(50, 50, 50, 50)];
UIImage *image = [UIImage imageNamed:@"MyBundle.bundle/img_collect_success"];
[imgView setImage:image];
或者
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];
3.VC获得bundle中的资源
NSString * bundlePath = [[ NSBundle mainBundle] pathForResource: @ "MyBundle" ofType :@ "bundle"];
NSBundle *resourceBundle = [NSBundle bundleWithPath:bundlePath];
UIViewController *vc = [[UIViewController alloc] initWithNibName:@"vc_name" bundle:resourceBundle];
当然，可以写成预编译语句：
#define MYBUNDLE_NAME @ "MyBundle.bundle"
#define MYBUNDLE_PATH [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent: MYBUNDLE_NAME]
#define MYBUNDLE [NSBundle bundleWithPath: MYBUNDLE_PATH]
