路径读取

//文件路径+ (NSString *)pathForResourceFileName:(NSString *)fileName ofType:(NSString *)type{    return [[NSBundle mainBundle] pathForResource:fileName ofType:type];}+ (NSString *)pathForDocumentFileName:(NSString *)fileName{    // 目录列表    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);    // 根目录    NSString *documentsDirectory = [paths objectAtIndex:0];    return [documentsDirectory stringByAppendingPathComponent:fileName];}

+ (BOOL)fileExist:(NSString *)path{    NSFileManager *file_manager = [NSFileManager defaultManager];    return [file_manager fileExistsAtPath:path];}//判断文件是否存在
