NSPathUtilities，关于文件路径的几个常用操作

NSPathUtilities，关于文件路径的几个常用操作，熟悉一下，拼接路径什么的，感觉还是挺好使的。

    //原路径。随便在项目中添加了张图片，用于测试        NSString *strPath =[[NSBundle mainBundle] pathForResource:@"002" ofType:@"png"];        NSLog(@"path======%@", strPath);                //获取路径的最后一层        NSString *strAllName = [strPath lastPathComponent];        NSLog(@"allName===%@",strAllName);                //去掉路径的最后一层        NSString *strFilePath = [strPath stringByDeletingLastPathComponent];        NSLog(@"filePath==%@",strFilePath);                //去掉扩展名        NSString *strName = [strAllName stringByDeletingPathExtension];        NSLog(@"strName===%@",strName);                //获取扩展名        NSString *strExtension = [strPath pathExtension];        NSLog(@"extension=%@",strExtension);  

    运行结果                 2015-05-06 18:20:48.638 test03[3470:1708111] path======/private/var/mobile/Containers/Bundle/Application/9A142EC0-A29F-42DF-AFF6-C36E448271AE/test03.app/002.png        2015-05-06 18:20:48.639 test03[3470:1708111] allName===002.png        2015-05-06 18:20:48.640 test03[3470:1708111] filePath==/private/var/mobile/Containers/Bundle/Application/9A142EC0-A29F-42DF-AFF6-C36E448271AE/test03.app        2015-05-06 18:20:48.640 test03[3470:1708111] strName===002        2015-05-06 18:20:48.641 test03[3470:1708111] extension=png
