Answer 2

您可能想尝试锁定焦点以禁用自动对焦。这是一个示例代码：

 NSArray *devices = [AVCaptureDevice devices];
    NSError *error;
    for (AVCaptureDevice *device in devices) {
        if (([device hasMediaType:AVMediaTypeVideo]) && 
            ([device position] == AVCaptureDevicePositionBack) ) {
            [device lockForConfiguration:&error];
             if ([device isFocusModeSupported:AVCaptureFocusModeLocked]) {
             device.focusMode = AVCaptureFocusModeLocked;
             NSLog(@"Focus locked");
             }

            [device unlockForConfiguration];
        }
    }

你也可以尝试将.showsCameraControls你的选择器控制器的属性设置为 NO 应该删除焦点方块（它在 4.3 之前做了，我认为没有任何改变），但缺点是你需要提供自己的控件（采取照片等）。
