Usage

Initialize

    NSString *path = [[NSBundle mainBundle] pathForResource:@"videoName"
                                                     ofType:@"MP4"];
    YGCTrimVideoView *ygcTrimView = [[YGCTrimVideoView alloc] initWithFrame:CGRectMake(0, 75, self.view.bounds.size.width, 80)
                                                       assetUR:[NSURL fileURLWithPath:path]];
    [self.view addSubview:self.ygcTrimView];

or pass the asset to YGCTrimVideoView directly.It has different initialize method.

Make custom UI

- (id)initWithFrame:(CGRect)frame
   leftControlImage:(UIImage *)leftImage
  rightControlImage:(UIImage *)rightImage
   centerRangeImage:(UIImage *)centerImage
       sideBarWidth:(CGFloat)sidebarWidth;

• leftImage you could setup your left sidebar with a image
• rightImage same as leftImage
• centerRangeImage the border image around the slider, maybe required set the image's resize inset
• sideBarWidth the control bar width

Setup maximum duration and minimum duration

just setup the property maxSeconds and minSeconds.

// min duration is 2 and max duration is 10 
self.ygcTrimView.minSeconds = 2;
self.ygcTrimView.maxSeconds = 10;

Preview the cropped video

in the delegate funtion

- (void)dragActionEnded:(AVMutableComposition *)asset

every time your finished dragging the control bar YGCTrimView will generate a AVMutableCompsition.You could create a AVPlayer and play the composition directly. like

- (void)dragActionEnded:(AVMutableComposition *)asset {
  self.playerItem = [[AVPlayerItem alloc] initWithAsset:asset];
  [self.player replaceCurrentItemWithPlayerItem:self.playerItem];
  [self.player play];

}

Export Video

YGCTrimVideoView support two ways to export a video file.
First Method

- (void)dragActionEnded:(AVMutableComposition *)asset;

get a AVMutableComposition from the delegate function. An AVMutableComposition is an AVAsset.So you could use AVExportSession to export a video file from AVMutableComposition.

Second Method

- (void)exportVideo:(YGCExportFinished)finishedBlock;

you could use the function directly to export a video file .The finishedBlock will give you the video url that from the sandbox.
