{
AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo]; if (authStatus == AVAuthorizationStatusDenied || authStatus == AVAuthorizationStatusRestricted) { // 没有权限。弹出alertView [self showAlert]; }else{ //获取了权限,直接调用相机接口 } }
- 弹出alertView

{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"相机权限未开启"
message:@"相机权限未开启,请进入系统【设置】>【隐私】>【相机】中打开开关,开启相机功能" delegate:nil cancelButtonTitle:@"取消" otherButtonTitles:@"立即开启", nil]; @weakify(self); [[alertView rac_buttonClickedSignal] subscribeNext:^(NSNumber *buttonIndex) { @strongify(self); if ([buttonIndex isEqualToNumber:@1]) { #ifdef __IPHONE_8_0 //跳入当前App设置界面, [[UIApplication sharedApplication]openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]]; #else //适配iOS7 ,跳入系统设置界面 [[UIApplication sharedApplication]openURL:[NSURL URLWithString:@"prefs:General&path=Reset"]]; #endif } }]; [alertView show]; }
1.3 参数说明
