Ios中获取文件路径的4种方法

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask,

YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *writableDBPath = [documentsDirectory stringByAppendingPathComponent:filename];   

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

NSHomeDirectory(),FILE_NAME]

//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]

NSString* filePath = [[NSBundle mainBundle] pathForResource:@"fileName" ofType:@"fileType

(txt...html..)"];
