Matlab：实现音频均衡器IOS模式

switch nargin
    case 3
        
        switch action
            
            case 'DeviceChoice'
                DeviceChoice = get_param(blk, 'DeviceChoice');
                maskObj = Simulink.Mask.get(blk);
                hostInputSelectorParam = maskObj.Parameters(2);
                iOSInputSelectorParam = maskObj.Parameters(3);
                
                if strcmp(DeviceChoice, 'Run on host') == 1
                    set_param(strcat(blk, '/Manual Variant Sink'), 'LabelModeActiveChoice', 'V_1');
                    iOSInputSelectorParam.set('Visible', 'off');
                    hostInputSelectorParam.set('Visible', 'on');
                    HelperAudioEqualizeriOS(blk, sys, 'InputChoice');
                    set_param(sys, 'SimulationMode', 'normal');
                    set_param(sys, 'HardwareBoard', 'None');
                    set_param(sys, 'IsERTTarget','off');
                elseif strcmp(DeviceChoice, 'Run on Apple iOS device') == 1
                    set_param(strcat(blk, '/Manual Variant Sink'), 'LabelModeActiveChoice', 'V_2');
                    hostInputSelectorParam.set('Visible', 'off');
                    iOSInputSelectorParam.set('Visible', 'on');

                    set_param(sys, 'SimulationMode', 'external');
                    set_param(sys, 'HardwareBoard', 'Apple iOS Device');
                    set_param(sys, 'IsERTTarget','on');
                    
                    % update sample rate and frame size for iOS blocks, since we disable iOS
                    % block sample rate and frame size update when user doesn't have iOS
