Question

我需要为SR BC中的字段设置计算值。我需要检查用户的当前登录名。因此，如果用户不是kr0001，kr0002等，它应该执行一些其他操作

我对计算值的表达式：

IIF(LoginName() = "kr0001", "Y", "")

如何修改此功能以实现上述目标？我可以使用％＆＃39;％喜欢％＆＃39;在这里运作？

您仍然使用equals运算符，但使用通配符作为通配符。

NSDictionary *pixBuffAttributes = @{                                                                                      
    (id)kCVPixelBufferWidthKey:@(nWidth),                                 
    (id)kCVPixelBufferHeightKey:@(nHeight),                                  
    (id)kCVPixelBufferCGImageCompatibilityKey:@YES,
};
m_output = [[AVPlayerItemVideoOutput alloc] initWithPixelBufferAttributes:pixBuffAttributes];

...

m_buffer = [m_output copyPixelBufferForItemTime:time itemTimeForDisplay:NULL];

CVPixelBufferLockBaseAddress(m_buffer, 0);
auto *buffer = CVPixelBufferGetBaseAddress(m_buffer);
frame->width = CVPixelBufferGetWidth(m_buffer);
frame->height = CVPixelBufferGetHeight(m_buffer);
frame->widthbytes = CVPixelBufferGetBytesPerRow(m_buffer);
frame->bufferlen = frame->widthbytes * (uint32)CVPixelBufferGetHeight(m_buffer);

auto &videoInfo = m_info.video;
CGDataProviderRef dp = CGDataProviderCreateWithData(nullptr, buffer, frame->bufferlen, nullptr);
CGColorSpaceRef cs = CGColorSpaceCreateDeviceRGB();
m_image = CGImageCreate(frame->width,
                        frame->height,
                        8,
                        videoInfo.pixelbits,
                        frame->widthbytes,
                        cs,
                        kCGImageAlphaNoneSkipFirst,
                        dp,
                        nullptr,
                        true,
                        kCGRenderingIntentDefault);
CGColorSpaceRelease(cs);
CGDataProviderRelease(dp);
