Question

尝试编写一个快速的Unity插件来从剪贴板中取出数据，所讨论的功能如下：

extern "C"
    {
        const char * _importString()
        {
            UIPasteboard *result = [UIPasteboard generalPasteboard];
            NSString * resultString = [result string];
            return [resultString UTF8String];
        }
    }

但是，当我激活该功能时，它会给我以下错误：

GfxDevice: creating device client; threaded=1

ProductName(8608,0x1b8100b40) malloc: *** error for object 0x1740a6191: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug

主要用Unity C编写，所以对iOS插件知之甚少，也不知道从哪里开始，任何帮助都有所帮助。

编辑：

对于那些在家里玩的人来说，这里是相关的Unity片段：

[DllImport("__Internal")]
private static extern string _importString();

//retrieves the clipboard contents from xcode
public string iPhoneImportClipboard()
{
    return _importString();
}

sudo apt-get install gcc的结果不能被视为malloc指针。

在返回之前，您需要-string一个缓冲区和malloc字符串。

strcpy
