    //这里是app的Bundle的地址,获取的路径是你程序的安装路径下的资源文件位置
    NSString *appPath =[[NSBundle mainBundle] bundlePath];     NSLog(@"%@",appPath);   
    //这个方法能获取一个数组,数组里面印象中是2个路径,但是ios只有一个,在IOS中使用的时候,直接用数组中的第一个即可,第一个参数为你要的路径的类型,此处为获取Document文件夹   
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentationDirectory, NSUserDomainMask , YES);
    NSString *Path =[paths objectAtIndex:0]      NSLog(@"%@",Path);           
    //同上,但是获取的是Library文件夹
    NSArray *paths2 = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES); 
    NSString *Path2 =[paths2 objectAtIndex:0]      NSLog(@"%@",Path2);           
    //同上,但是获取的是Caches文件夹
    NSArray *paths3 = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES); 
    NSString *Path3 =[paths3 objectAtIndex:0]      NSLog(@"%@",Path3);  
    //获取tmp文件夹路径
    NSString * tmpDir = NSTemporaryDirectory();     NSLog(@"%@",tmpDir);      
    //获取应用程序目录路径(里面有Document,Library和temp文件夹
    NSString * homeDir = NSHomeDirectory();     NSLog(@"%@",homeDir);  
    //获取项目中文件的目录 
    NSString * fileDir = [[NSBundle mainBundle] pathForResource:@"pic1" ofType:@"jpg"];     NSLog(@"%@",fileDir);      
    fileDir = [[NSBundle mainBundle] pathForResource:@"pic2.jpg" ofType:nil];     NSLog(@"%@",fileDir);      
    //工程下黄色目录是虚拟目录.蓝色目录是真实目录 
    fileDir = [[NSBundle mainBundle] pathForResource:@"pic3.jpg" ofType:nil inDirectory:@"img"]; 
    NSLog(@"%@",fileDir);  
    fileDir = [[NSBundle mainBundle] pathForResource:@"img/pic4.jpg" ofType:nil inDirectory:nil]; 
    NSLog(@"%@",fileDir);
