        NSArray *paths=NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

        NSString *path=[paths objectAtIndex:0];

        NSString *dest=[path stringByAppendingPathComponent:@" "];

        NSLog(@"%@",tmpContent);

        [self loadHTMLString:tmpContent baseURL:[NSURL fileURLWithPath:dest]];

上面紅字型的解釋：

若用 stringByAppendingString  則需要手動在名稱前加 “/”符號，而stringByAppendingPathComponent則不需要，它會自動添加

stringByAppendingPathComponent和stringByAppendingString的區別：

 NSString *imagePath = [skinPath stringByAppendingString:[NSString stringWithFormat:@"/%@",imageName]];//stringByAppendingString是在skinPath加尾碼的意思    NSString *imagePath = [skinPath stringByAppendingPathComponent:imageName];//stringByAppendingPathComponent是在skinPath後面加上“／”號串連imageName讓它成為完整的路徑    NSLog(@"imagePath:%@",imagePath);
