AVPlayerview comes from top left corner - ios

Question

I'm using AVPlayer to play videos. I have an issue on fullscreen mode. Video player comes from top left corner. It looks odd.
NSString *filePath = [self.video_Array objectAtIndex:index];
NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:filePath ofType: nil];
url = [[NSURL alloc] initFileURLWithPath: soundFilePath];
currentItem = [AVPlayerItem playerItemWithURL:url];
_playerViewController = [[AVPlayerViewController alloc] init];
_playerViewController.videoGravity = AVLayerVideoGravityResize;
_playerViewController.view.frame = self.view.bounds;
_playerViewController.showsPlaybackControls = NO;
_video=[AVPlayer playerWithURL:url];
_video = [AVPlayer playerWithPlayerItem:currentItem];
_playerViewController.player = _video;
[_playerViewController.player play];
[self.view addSubview:_playerViewController.view];

Please refer my code which is working fine in my application,
-(void)videoPlayer:(NSString *)filePath{
playerViewController = [[AVPlayerViewController alloc] init];
self.viewPlayerContainer.frame = CGRectMake(0, 74, self.view.bounds.size.width, self.view.bounds.size.width);
NSURL *url = [NSURL fileURLWithPath:filePath];
AVURLAsset *asset = [AVURLAsset assetWithURL: url];
AVPlayerItem *item = [AVPlayerItem playerItemWithAsset: asset];
AVPlayer * player = [[AVPlayer alloc] initWithPlayerItem: item];
playerViewController.player = player;
playerViewController.videoGravity = AVLayerVideoGravityResizeAspectFill;
[playerViewController.view setFrame:CGRectMake(0, 0, self.viewPlayerContainer.bounds.size.width, self.viewPlayerContainer.bounds.size.height)];
[playerViewController addObserver:self forKeyPath:#"videoBounds" options:NSKeyValueObservingOptionNew context:nil];
playerViewController.showsPlaybackControls = YES;
[self.viewPlayerContainer addSubview:playerViewController.view];
[player play];
}

You can use AVPlayerViewController to play fullscreen video
AVPlayerViewController+Fullscreen.h
#import <AVKit/AVKit.h>
#interface AVPlayerViewController (Fullscreen)
-(void)goFullscreen;
#end
AVPlayerViewController+Fullscreen.m
#import "AVPlayerViewController+Fullscreen.h"
#implementation AVPlayerViewController (Fullscreen)
-(void)goFullscreen {
self.modalPresentationStyle = UIModalPresentationOverFullScreen;
[self presentViewController:self animated:YES completion:nil];
}
#end
