前段时间封装了一个视频播放器使用AVPlayer自定义支持全屏的播放器（三），经过一段时间的测试，发现了许多bug，针对以前遗留的问题进行了修复和更新。
修复bug主要修复了播放器页面不支持旋转引起全屏音量图标未旋转，进度条拖拽不灵敏，Masonry引起约束警告，网络不好销毁播放器引起卡顿以及一些小问题。
1.旋转后音量图标不旋转bug开始使用的是旋转播放器来实现全屏，开题报告，实际页面未旋转，所以系统音量图标方向不对，开题报告，修改后采用页面旋转来实现全屏，这样就不会引起系统音量图标方向不对，具体如何使页面支持旋转，并且不影响其他页面请看这里iOS页面旋转详解。
2.进度条拖拽不灵敏由于自定义了进度条的图标，引起进度条拖拽不灵敏，这里在自定义进度条内部重写- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event，- (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event这两个方法，增大响应的范围。
代码//检查点击事件点击范围是否能够交给self处理 - (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event { //调用父类方法,找到能够处理event的view UIView* result = [super hitTest:point withEvent:event]; if (result != self) { /*如果这个view不是self,我们给slider扩充一下响应范围, 这里的扩充范围数据就可以自己设置了 */ if ((point.y >= -15) && (point.y < (_lastBounds.size.height + SLIDER_Y_BOUND)) && (point.x >= 0 && point.x < CGRectGetWidth(self.bounds))) { //如果在扩充的范围类,就将event的处理权交给self result = self; } } //否则,返回能够处理的view return result; } //检查是点击事件的点是否在slider范围内 - (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event { //调用父类判断 BOOL result = [super pointInside:point withEvent:event]; if (!result) { //同理,如果不在slider范围类,扩充响应范围 if ((point.x >= (_lastBounds.origin.x - SLIDER_X_BOUND)) && (point.x <= (_lastBounds.origin.x + _lastBounds.size.width + SLIDER_X_BOUND)) && (point.y >= -SLIDER_Y_BOUND) && (point.y < (_lastBounds.size.height + SLIDER_Y_BOUND))) { //在扩充范围内,返回yes result = YES; } } //否则返回父类的结果 return result; }新增功能新增加了转子动画，增加拖拽后转子衔接动画，增加各类接口。
转子动画采用CAShapeLayer和UIBezierPath做了一个简单的加载动画。
代码@interface AILoadingView ()<CAAnimationDelegate> @property(nonatomic,strong)CAShapeLayer *loadingLayer; /** 当前的index*/ @property(nonatomic,assign)NSInteger index; /** 是否能用*/ @property(nonatomic,assign,getter=isEnable)BOOL enable; @end @implementation AILoadingView - (instancetype)initWithFrame:(CGRect)frame { self = [super initWithFrame:frame]; if (self) { _index = 0; _enable = YES; _duration = 2.; [self createUI]; } return self; } -(void)layoutSubviews { [super layoutSubviews]; UIBezierPath *path = [self cycleBezierPathIndex:_index]; self.loadingLayer.path = path.CGPath; } - (UIBezierPath*)cycleBezierPathIndex:(NSInteger)index { UIBezierPath *path = [UIBezierPath bezierPathWithArcCenter:CGPointMake(self.bounds.size.width * 0.5, self.bounds.size.height *0.5) radius:self.bounds.size.width * 0.5 startAngle:index * (M_PI* 2)/3 endAngle:index * (M_PI* 2)/3 + 2*M_PI * 4/3 clockwise:YES]; return path; } - (void)createUI { self.loadingLayer = [CAShapeLayer layer]; self.loadingLayer.lineWidth = 2.; self.loadingLayer.fillColor = [UIColor clearColor].CGColor; self.loadingLayer.strokeColor = [UIColor blackColor].CGColor; [self.layer addSublayer:self.loadingLayer]; self.loadingLayer.lineCap = kCALineCapRound; } - (void)loadingAnimation { CABasicAnimation *strokeStartAnimation = [CABasicAnimation animationWithKeyPath:@'strokeStart']; strokeStartAnimation.fromValue = @0; strokeStartAnimation.toValue = @1.; strokeStartAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]; CABasicAnimation *strokeEndAnimation = [CABasicAnimation animationWithKeyPath:@'strokeEnd']; strokeEndAnimation.fromValue = @.0; strokeEndAnimation.toValue = @1.; strokeEndAnimation.duration = self.duration * 0.5; CAAnimationGroup *strokeAniamtionGroup = [CAAnimationGroup animation]; strokeAniamtionGroup.duration = self.duration; strokeAniamtionGroup.delegate = self; strokeAniamtionGroup.animations = @[strokeEndAnimation,strokeStartAnimation]; [self.loadingLayer addAnimation:strokeAniamtionGroup forKey:@'strokeAniamtionGroup']; } #pragma mark -CAAnimationDelegate -(void)animationDidStop:(CAAnimation *)anim finished:(BOOL)flag { if (!self.isEnable) { return; } _index++; self.loadingLayer.path = [self cycleBezierPathIndex:_index %3].CGPath; [self loadingAnimation]; } #pragma mark -public - (void)starAnimation { if (self.loadingLayer.animationKeys.count > 0) { return; } self.hidden = NO; self.enable = YES; [self loadingAnimation]; } - (void)stopAnimation { self.hidden = YES; self.enable = NO; [self.loadingLayer removeAllAnimations]; } - (void)setStrokeColor:(UIColor *)strokeColor { _strokeColor = strokeColor; self.loadingLayer.strokeColor = strokeColor.CGColor; }播放器效果图总结 本次主要是修复以前遗留的bug，完善了各种情况的Demo，优化了体验，具体请在github下载CLPlayer ， 如果喜欢，欢迎star。
