Для отображения потока во весь экран рекомендуется использовать RTCMTLVideoView, поскольку RTCEAGLVideoView искажает пропорции при изменении размеров

id<MTLDevice> remoteDevice;
#ifdef __aarch64__
remoteDevice = MTLCreateSystemDefaultDevice();
if (remoteDevice) {
RTCMTLVideoView *remoteView = [[RTCMTLVideoView alloc] init];
remoteView.delegate = self;
remoteView.videoContentMode = UIViewContentModeScaleAspectFit;
_remoteDisplay = remoteView;
_remoteDisplay.backgroundColor = [UIColor blackColor];
UITapGestureRecognizer *singleFingerTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(fullscreenButton:)];
singleFingerTap.numberOfTapsRequired = 2;
[_remoteDisplay addGestureRecognizer:singleFingerTap];
}
#endif
if (!_remoteDisplay) {
RTCEAGLVideoView *remoteView = [[RTCEAGLVideoView alloc] init];
remoteView.delegate = self;
_remoteDisplay = remoteView;
}
_remoteDisplay.translatesAutoresizingMaskIntoConstraints = NO; |
Для переключения в полный экран задаем элементу, в котором проигрывается поток, размеры экрана в качестве максимальных

[_remoteDisplay.widthAnchor constraintEqualToConstant: [[UIScreen mainScreen] bounds].size.width].active = YES;
[_remoteDisplay.heightAnchor constraintEqualToConstant:[[UIScreen mainScreen] bounds].size.height].active = YES;
[_remoteDisplay removeFromSuperview];
[_scrollView addSubview:_remoteDisplay]; |
Для выхода из полноэкранного режима задаем элементу, в котором проигрывается поток, размеры контейнера на экране

[_remoteDisplay removeFromSuperview];
[_videoContainer addSubview:_remoteDisplay];
NSLayoutConstraint *constraint =[NSLayoutConstraint constraintWithItem:_remoteDisplay attribute:NSLayoutAttributeWidth relatedBy:NSLayoutRelationEqual toItem:_remoteDisplay attribute:NSLayoutAttributeHeight multiplier:640.0/480.0 constant:0];
[_remoteDisplay addConstraint:constraint];

[_videoContainer addConstraint:constraint];
[_videoContainer addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|[remoteDisplay]|" options:NSLayoutFormatAlignAllTop metrics:@{} views:@{@"remoteDisplay": _remoteDisplay}]];
