使用Objective-c实现Tom猫《二》

2.选择 createfolder references for any
folders，文件夹是蓝色，运行程序时，他会在Bundel中再细分文件夹(以下图为例：运行程序后会在Bundel包中再细分Animations/……)

*/把素材(素材存放在Animations中，Animations又细分Angry,Drink…)从finder中拉倒Supporting
Files,按如下图所示打钩，

26     NSMutableArray *arrayM = [NSMutableArray array];

27     // 获取Animatiosns路径

28     NSString *bundlePath = [[[NSBundle mainBundle] bundlePath] stringByAppendingPathComponent:@"Animations"];

29     // 追加路径

30     NSString *animPath = [bundlePath stringByAppendingPathComponent:name]; // 假如传的name值为Drink，则animPath值为  bundel路径/Animations/Drink


31

32     // NSFileManager是专门用来做磁盘文件管理的

33     // 取出指定目录中的所有文件

34     NSArray *files = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:animPath error:NULL];

41     }

43     self.tom.animationImages = arrayM;

44     self.tom.animationDuration = arrayM.count * 0.075;

47     // 2. 开始播放

48     [self.tom startAnimating];

50     // 3. 清空动画数组

51     [self.tom performSelector:@selector(setAnimationImages:) withObject:nil afterDelay:self.tom.animationDuration];

52 }

53

54 - (IBAction)tomAction:(UIButton *)button

55 {

56     [self runAnimationWithName:button.currentTitle]; // 先在storyboard中设置每个按钮的title，然后才能正确传参(title要跟文件夹名相同)
