前言

    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，实际页面未旋转，所以系统音量图标方向不对，修改后利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

利用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;
}
