1,document 中的路径  最麻烦的一种:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *writableDBPath = [documentsDirectory stringByAppendingPathComponent:filename;

 本人自写自用的宏

2,

#define ABS_FILE_PATH(FILE_NAME) [NSString stringWithFormat:@"%@/Documents/%@", NSHomeDirectory(),FILE_NAME]

  

3,获取程序application package目录下的文件路径:

#define PACKAGE_FILE_PATH(FILE_NAME) [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:FILE_NAME]

4,

NSString* filePath = [[NSBundle mainBundle] pathForResource:@"fileName" ofType:@"fileType(txt...html..)"];
