iOS深入探索直播推拉流实现流程(二：推流权限判断 )

　　推流权限判断实际上是对手机访问相机和麦克风权限的判断。如果连权限都没有怎么直播。需要注意的是，在iOS10以后，访问权限是需要在pilst里面申请的，这里自行脑补。

　　在LFLiveKit里面是没有这一步的，楼主不才，写了一个比较简单的权限检查方法以供参考。

#pragma mark --检查相机和麦克风的权限
//检查相机权限
- (void)checkCaptureDeviceEnableCheckCaptureVideo:(void(^)(BOOL isVideoSucc,NSString * err))succ{
    __weak ViewController * weakSelf = self;
    if ([AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo]==AVAuthorizationStatusNotDetermined) {
        [AVCaptureDevice requestAccessForMediaType:AVMediaTypeVideo completionHandler:^(BOOL granted) {
            if (granted) {
                [weakSelf checkCaptureAudioDeviceEnableCheckCaptureVideo:^(BOOL isAutioSucc, NSString *err) {
                    if (isAutioSucc) {succ(YES,nil);}
                    else{succ(NO,err);}
                }];
            }else{
                succ(NO,@"app需要访问您的摄像头。\n请启用摄像头-设置/隐私/摄像头");
            }
        }];
    }else if([AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo]==AVAuthorizationStatusAuthorized){
        [self checkCaptureAudioDeviceEnableCheckCaptureVideo:^(BOOL isAutioSucc, NSString *err) {
            if (isAutioSucc) {succ(YES,nil);}
            else{succ(NO,err);}
        }];
    }else{
        succ(NO,@"app需要访问您的摄像头。\n请启用摄像头-设置/隐私/摄像头");
    }
}
//检查麦克风权限
- (void)checkCaptureAudioDeviceEnableCheckCaptureVideo:(void(^)(BOOL isAutioSucc,NSString * err))succ{
    if ([AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeAudio]==AVAuthorizationStatusNotDetermined) {
        [AVCaptureDevice requestAccessForMediaType:AVMediaTypeAudio completionHandler:^(BOOL granted) {
            if (granted) {succ(granted,nil);}
            else{succ(NO,@"app需要访问您的麦克风。\n请启用麦克风-设置/隐私/麦克风");}
        }];
    }else if([AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeAudio]==AVAuthorizationStatusAuthorized){
        succ(YES,nil);
    }else{
        succ(NO,@"app需要访问您的麦克风。\n请启用麦克风-设置/隐私/麦克风");
    }
}

　　　权限判断完成以后就相当于正式进入了LFLiveKit的学习。
