如何检测代码中的“警报 LED 闪烁”(来自设置)状态?我努力了:
AVCaptureDevice *torched=[AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];
BOOL test = torched.torchMode;
BOOL test1 = torched.flashMode;
但它似乎不是我需要的。
这样做,
BOOL test=NO;
BOOL test1=NO;
Class captureDeviceClass = NSClassFromString(@"AVCaptureDevice");
if (captureDeviceClass != nil) {
AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];
if ([device hasTorch] && [device hasFlash]){
if(device.flashMode==AVCaptureFlashModeOn)
NSLog(@"ON");
else
NSLog(@"OFF");
}
}
希望对你有帮助......
