相机对焦支持传入一个坐标然后相机根据这个坐标进行对焦吗

let focusModeStatus: boolean = false; 
try {let status: boolean = captureSession.isFocusModeSupported(camera.FocusMode.FOCUS_MODE_CONTINUOUS_AUTO); 
focusModeStatus = status; 
} catch (error) { 
let err = error as BusinessError; 
console.error('Failed to check whether the focus mode is supported. errorCode = ’ + err.code); 
} 
if (focusModeStatus) { 
try { 
captureSession.setFocusMode(camera.FocusMode.FOCUS_MODE_CONTINUOUS_AUTO); 
}  
catch (error) { 
let err = error as BusinessError; 
console.error('Failed to set the focus mode. errorCode = ’ + err.code); 
} 
}
