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
