1.中文连接在编码后就无法正常显示问题修改

修改方法：只对参数进行编码

+ (nullable instancetype)hu_URLWithString:(NSString *)urlString{
    
    NSString *realEncodeUrl;
    NSArray *arr = [urlString componentsSeparatedByString:@"?"];
    if (arr.count > 1) {
        NSString *paramPart = arr[1];
        //ios 9以上系统
        if (NSFoundationVersionNumber >= NSFoundationVersionNumber_iOS_9_0){
            paramPart = [urlString stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLFragmentAllowedCharacterSet]];
        }else{
            paramPart = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
        }
        realEncodeUrl = [NSString stringWithFormat:@"%@?%@",arr[0],paramPart];
        
    }else{
        realEncodeUrl = urlString;
    }
    
    if ([realEncodeUrl hasPrefix:@"http"]) {
        return [self URLWithString:realEncodeUrl];
    }else{
        return nil;
    }
}

1.NSString *encodedValue = [url stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

1.本地url链接组装
//法1：(推荐用公共接口管理方便)

NSString *filePath = [HsURLUtil appPathWithFileName:@“test.mp4"];
NSURL *url = [NSURL fileURLWithPath:str];

//法2：（其实本质是一样的）

NSString *str = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"mp4"];
NSURL *url = [NSURL fileURLWithPath:str];

2.公共接口实现部分
//根据传入文件名，返回关键目录根目录加上文件的绝对路径 document

+ (NSString *)dataFilePathWithFileName:(NSString *)fileName WithDirType:(NSSearchPathDirectory)dirType
{
    NSArray *paths = NSSearchPathForDirectoriesInDomains(dirType, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *absolutefileName = [fileName lastPathComponent];
    return [documentsDirectory stringByAppendingPathComponent:absolutefileName];
}
//根据传入的相对路径，返回基于全局的关键目录的绝对路径
+ (NSString *)dataFilePathWithFilePath:(NSString *)fileName WithDirType:(NSSearchPathDirectory)dirType;
{
    NSArray *paths = NSSearchPathForDirectoriesInDomains(dirType, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    return [documentsDirectory stringByAppendingPathComponent:fileName];
}

eg:使用

NSString *filePath = [HsURLUtil dataFilePathWithFileName:@"trade_function_config.xml.encode" WithDirType:NSDocumentDirectory];

//根据传入文件名，返回安装目录加上文件名的绝对路径 app

+ (NSString *)appPathWithFileName:(NSString *)fileName
{
    NSString *filePath = [[NSBundle mainBundle] pathForResource:@"Info" ofType:@"plist"];
    filePath = [filePath stringByDeletingLastPathComponent];
    NSString *absolutefileName = [fileName lastPathComponent];
    // TRACELOG([filePath stringByAppendingPathComponent:absolutefileName]);
    return [filePath stringByAppendingPathComponent:absolutefileName];
}
//根据传入的相对路径，返回基于安装目录的绝对路径
+ (NSString *)appPathWithFilePath:(NSString *)filePath
{
    NSString *appPath = [[NSBundle mainBundle] pathForResource:@"Info" ofType:@"plist"];
    appPath = [appPath stringByDeletingLastPathComponent];
    //NSString *absolutefileName = [fileName lastPathComponent];
    // TRACELOG([filePath stringByAppendingPathComponent:absolutefileName]);
    return [appPath stringByAppendingPathComponent:filePath];
}

eg:使用

NSString *filePath = [HsURLUtil appPathWithFileName:@"JF-info.plist.encode"];
