//1.获取沙盒数据容器根目录    NSString *homePath = NSHomeDirectory();    NSLog(@"home根目录:%@", homePath);    //2.获取Documents路径    /*参数一：指定要搜索的文件夹枚举值      参数二：指定搜索的域Domian: NSUserDomainMask      参数三：是否需要绝对/全路径：NO：波浪线~标识数据容器的根目录; YES(一般制定): 全路径     */     NSString *documentPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject];    NSLog(@"documens路径:%@", documentPath);    //3.获取Library路径    NSString *libraryPath = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES) lastObject];    NSLog(@"libaray路径:%@", libraryPath);    //4.获取tmp路径    NSString *tmpPath = NSTemporaryDirectory();    NSLog(@"tmp路径：%@", tmpPath);

另一种方法

NSString *documents = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];    //拼接文件绝对路径    NSString *path = [documents stringByAppendingPathComponent:@"header.png"];
