读取已连接设备的可选相机固件版本。

前置条件

• 设备已连接且就绪。
• 设备符合 DeviceCameraAPI。

API 参考

框架

AIBuds.xcframework

导入

Swift

Swift

import AIBuds

Objective-C

Objective-C

#import <AIBuds/AIBuds-Swift.h>
#import <AIBuds/AIBuds.h>

协议属性

Swift

Swift

/// The protocol for device API that supports camera.
protocol DeviceCameraAPI: DeviceAPI {
    /// Camera firmware version string, may be nil if unavailable.
    var cameraFirmwareVersion: String? { get }
}

Objective-C

Objective-C

/// The protocol for device API that supports camera.
@protocol AIBudsDeviceCameraAPI <AIBudsDeviceAPI>
/// Camera firmware version string, may be nil if unavailable.
@property(nonatomic, readonly, copy) NSString *_Nullable cameraFirmwareVersion;
@end

请在 API Reference 中参阅 cameraFirmwareVersion。

使用示例

Swift

Swift

guard let device = device as? DeviceCameraAPI else {
    print("Device does not support camera APIs")
    return
}

print(device.cameraFirmwareVersion ?? "Camera firmware version unavailable")

Objective-C

Objective-C

id<AIBudsDeviceCameraAPI> device = (id<AIBudsDeviceCameraAPI>)self.device;
if ([device conformsToProtocol:@protocol(AIBudsDeviceCameraAPI)]) {
    NSLog(@"%@", device.cameraFirmwareVersion ?: @"Camera firmware version unavailable");
}

nil 表示该值不可用，不代表需要重试的操作失败。
