ios - NSTask 不适用于具有特殊字符的文件路径

Question

我正在使用 NStask 来获取文件夹大小。它对于普通文件路径(如 home/ABC/Users/testUser/Documents)工作正常。但它没有显示 home/ABC/Users/testUser/Ω≈ç∂√√√∂ƒ∂ 等文件路径的任何输出。但是我在终端上获得相同文件路径的正确输出。有什么建议吗？

    NSString* userName = @"test123_test123";
    NSString* password = @"test";
    NSString* serverIP = @"200.144.172.210";
    NSString* sizeFolderPath = [[NSBundle mainBundle] pathForResource:@"demoUtilities" ofType:nil];

    NSString* xml= @"--test";
    NSString* passwordArg = [NSString stringWithFormat:@"--pwd-=%@",password];

    NSString *filePath = @"UsersMac/Users/test/Ω≈ç∂√√√∂ƒ∂";
    NSString* address = [NSString stringWithFormat:@"%@@%@::home/%@", userName,   serverIP,filePath];
    NSArray* arguments = [NSMutableArray arrayWithObjects:xml,passwordArg,address,nil];

    TestCommandExcecuter *cmExec = [[TestCommandExcecuter alloc]init];
    [cmExec setCommandString:sizeFolderPath];
    [cmExec setCommandArguments:arguments];

我正在使用此代码:

从 2.0 开始已弃用

 NSDictionary *fileDictionary = [[NSFileManager defaultManager]   
                                    fileAttributesAtPath:filePath traverseLink:YES];

long long size = [fileDictionary fileSize];
 NSLog(@"size :: %lld",size);

最新:

 NSDictionary *fileDictionary = [[NSFileManager defaultManager] 
                                     attributesOfItemAtPath:filePath error:nil];

long long size = [fileDictionary fileSize];
NSLog(@"size :: %lld",size);
