概述
广播跑马灯/弹幕/直播点赞/烟花/雪花等动画特效, 后续增加~
详细
一、实现功能
1. 广播跑马灯
2. 弹幕动画
3. 直播点赞动画
4. 直播点赞图片动画
5. 烟花动画
6. 雪花动画
二、程序实现
1. 广播动画特效:
思路:
1. 初始化广播视图
2. 设置广播公告广告内容
3. 添加动画效果
初始化广播视图, 广播活动标题按钮 与 广播活动标题标签 控件大小一样
/**
* 设置广播视图
*/
- (void)setupBroadcastingView {
// 设置广播活动标题按钮
UIButton *activityBtn = [UIButton buttonWithType:UIButtonTypeCustom];
activityBtn.frame = CGRectMake(0, 64, [UIScreen mainScreen].bounds.size.width, 30);
activityBtn.backgroundColor = [UIColor clearColor];
[activityBtn addTarget:self action:@selector(activityDetail) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:activityBtn];
self.activityBtn = activityBtn; // 设置广播活动标题文字
UILabel *activityLb = [[UILabel alloc] init];
activityLb.frame = activityBtn.bounds;
[activityLb setFont:[UIFont boldSystemFontOfSize:14]];
[activityLb setTextColor:[UIColor colorWithRed:115/255.0 green:125/255.0 blue:134/255.0 alpha:1.0]];
[activityLb setBackgroundColor:[UIColor clearColor]];
[activityBtn addSubview:activityLb];
self.activityLb = activityLb; // 设置广播logo
UIImageView *speaker = [[UIImageView alloc] initWithImage:[UIImage imageNamed:[NSString stringWithFormat:@"broadcasting"]]];
speaker.frame = CGRectMake(0, 5, 20, 20);
speaker.backgroundColor = self.view.backgroundColor;
[activityBtn addSubview:speaker]; // 设置广播公告广告内容
[self setActivityButtonTitle];
}
设置广播公告广告内容, 这里是以假数据填充,一般需求会是后台请求得来的活动内容.
添加动画效果: 当文字内容超过显示区域就滚动展示,未超过则居中展示.
/**
* 设置广播公告广告内容
*/
- (void)setActivityButtonTitle { // 广播公告广告内容(假数据)
NSString *title = @"广播公告广告内容(ZL测试内容)广播公告广告内容(测试内容)\r\n广播公告广告内容(测试内容)广播公告广告内容(测试内容)广播公告广告内容(测试内容)"; title = [title stringByReplacingOccurrencesOfString:@"\r\n" withString:@" "]; [self.activityLb setText:title]; [self.activityLb sizeToFit]; if (self.activityLb.frame.size.width <= self.activityBtn.frame.size.width) { [self.activityLb setCenter:CGPointMake(self.activityBtn.frame.size.width/2, self.activityBtn.frame.size.height/2)]; } else { // 当文字内容超过显示区域就滚动展示 CGRect frame = self.activityLb.frame;
frame.origin.x = self.activityBtn.frame.size.width;
frame.origin.y = self.activityBtn.frame.size.height * 0.5 - self.activityLb.bounds.size.height * 0.5;
self.activityLb.frame = frame; [UIView beginAnimations:@"testAnimation" context:NULL];
[UIView setAnimationDuration:frame.size.width/55.f];
[UIView setAnimationCurve:UIViewAnimationCurveLinear];
[UIView setAnimationRepeatAutoreverses:NO];
[UIView setAnimationRepeatCount:INT_MAX]; frame = self.activityLb.frame;
frame.origin.x = - frame.size.width;
self.activityLb.frame = frame;
[UIView commitAnimations];
}
}
当有活动链接时,需要添加点击效果; 如果没则不需要创建按钮及点击效果.
// 展示活动详情
- (void)activityDetail { NSLog(@"点击了广播活动公告详情");
}
2. 弹幕动画特效:
先自定义弹幕标签ZLScrollLabelView:
.h 文件露出开始/停止/暂停/恢复弹幕动画
@interface ZLScrollLabelView : UIView
// 代理协议
@property (nonatomic, weak) id <ZLScrollLabelViewDelegate> delegate;
// 速度
@property (nonatomic) CGFloat speed;
// 方向
@property (nonatomic) ScrollDirectionType barrageDirection;
// 容器
- (void)addContentView:(UIView *)view;
// 开始
- (void)startAnimation;
// 停止
- (void)stopAnimation;
// 暂停
- (void)pauseAnimation;
// 恢复
- (void)resumeAnimation;
@end
.m 文件初始化:
- (instancetype)initWithFrame:(CGRect)frame {
if (self = [super initWithFrame:frame]) {
_width = frame.size.width;
_height = frame.size.height;
self.speed = 1.f;
self.barrageDirection = FromLeftType;
self.layer.masksToBounds = YES;
self.animationView = [[UIView alloc] initWithFrame:CGRectMake(_width, 0, _width, _height)];
[self addSubview:self.animationView];
}
return self;
}
- (void)addContentView:(UIView *)view {
[_contentView removeFromSuperview];
view.frame = view.bounds;
_contentView = view;
self.animationView.frame = view.bounds;
[self.animationView addSubview:_contentView];
_animationViewWidth = self.animationView.frame.size.width;
_animationViewHeight = self.animationView.frame.size.height;
}
开始弹幕动画:
- (void)startAnimation {
[self.animationView.layer removeAnimationForKey:@"animationViewPosition"];
_stoped = NO;
CGPoint pointRightCenter = CGPointMake(_width + _animationViewWidth / 2.f, _animationViewHeight / 2.f);
CGPoint pointLeftCenter = CGPointMake(-_animationViewWidth / 2, _animationViewHeight / 2.f);
CGPoint fromPoint = self.barrageDirection == FromLeftType ? pointRightCenter : pointLeftCenter;
CGPoint toPoint = self.barrageDirection == FromLeftType ? pointLeftCenter : pointRightCenter;
self.animationView.center = fromPoint;
UIBezierPath *movePath = [UIBezierPath bezierPath];
[movePath moveToPoint:fromPoint];
[movePath addLineToPoint:toPoint];
CAKeyframeAnimation *moveAnimation = [CAKeyframeAnimation animationWithKeyPath:@"position"];
moveAnimation.path = movePath.CGPath;
moveAnimation.removedOnCompletion = YES;
moveAnimation.duration = _animationViewWidth / 30.f * (1 / self.speed);
moveAnimation.delegate = self;
[self.animationView.layer addAnimation:moveAnimation forKey:@"animationViewPosition"];
}
停止弹幕动画:
- (void)stopAnimation {
_stoped = YES;
[self.animationView.layer removeAnimationForKey:@"animationViewPosition"];
}
- (void)animationDidStop:(CAAnimation *)anim finished:(BOOL)flag {
if (self.delegate && [self.delegate respondsToSelector:@selector(barrageView:animationDidStopFinished:)]) {
[self.delegate barrageView:self animationDidStopFinished:flag];
}
if (flag && !_stoped) {
[self startAnimation];
}
}
暂停弹幕动画:
- (void)pauseAnimation {
[self pauseLayer:self.animationView.layer];
}
- (void)pauseLayer:(CALayer*)layer {
CFTimeInterval pausedTime = [layer convertTime:CACurrentMediaTime() fromLayer:nil];
layer.speed = 0.0;
layer.timeOffset = pausedTime;
}
恢复弹幕动画:
- (void)resumeAnimation {
[self resumeLayer:self.animationView.layer];
}
- (void)resumeLayer:(CALayer*)layer {
CFTimeInterval pausedTime = layer.timeOffset;
layer.speed = 1.0;
layer.timeOffset = 0.0;
layer.beginTime = 0.0;
CFTimeInterval timeSincePause = [layer convertTime:CACurrentMediaTime() fromLayer:nil] - pausedTime;
layer.beginTime = timeSincePause;
}
在所需控制器里, 添加代理ZLScrollLabelViewDelegate实现开始动画方法
- (void)viewDidLoad {
[super viewDidLoad];
self.navigationItem.title = @"弹幕动画";
self.view.backgroundColor = [UIColor grayColor];
ZLScrollLabelView *barrageView0 = [[ZLScrollLabelView alloc] initWithFrame:CGRectMake(0, 104, self.view.frame.size.width, 20)];
barrageView0.delegate = self;
// add
[self.view addSubview:barrageView0];
// text
[barrageView0 addContentView:[self createLabelWithText:@"超喜欢赵丽颖,只因她的踏实!"
textColor:[self randomColor]]];
// start
[barrageView0 startAnimation];
}
代理ZLScrollLabelViewDelegate:
- (UILabel *)createLabelWithText:(NSString *)text textColor:(UIColor *)textColor {
NSString *string = [NSString stringWithFormat:@" %@ ", text];
CGFloat width = [string widthWithStringAttribute:@{NSFontAttributeName : [UIFont systemFontOfSize:14.f]}];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, width, 20)];
label.font = [UIFont systemFontOfSize:14.f];
label.text = string;
label.textColor = textColor;
return label;
}
#pragma mark - ZLScrollLabelViewDelegate
- (void)barrageView:(ZLScrollLabelView *)barrageView animationDidStopFinished:(BOOL)finished {
[barrageView stopAnimation];
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
[barrageView addContentView:[self createLabelWithText:[self randomString]
textColor:[self randomColor]]];
[barrageView startAnimation];
});
}
- (NSString *)randomString {
NSArray *array = @[@"猜猜我是谁?",
@"哈哈",
@"猜不着吧",
@"我是程序媛",
@"噜啦啦啦啦~"];
return array[arc4random() % array.count];
}
3. 直播点赞效果

} completion:NULL];
NSInteger i = arc4random_uniform(2);
// -1 OR 1
NSInteger rotationDirection = 1 - (2 * i);
NSInteger rotationFraction = arc4random_uniform(10);
[UIView animateWithDuration:totalAnimationDuration animations:^{
self.transform = CGAffineTransformMakeRotation(rotationDirection * M_PI / (16 + rotationFraction * 0.2));
} completion:NULL];
UIBezierPath *heartTravelPath = [UIBezierPath bezierPath];
[heartTravelPath moveToPoint:self.center];
// random end point
CGPoint endPoint = CGPointMake(heartCenterX + (rotationDirection) * arc4random_uniform(2 * heartSize), viewHeight/6.0 + arc4random_uniform(viewHeight / 4.0));
// random Control Points
NSInteger j = arc4random_uniform(2);
NSInteger travelDirection = 1- (2*j);
// randomize x and y for control points
CGFloat xDelta = (heartSize/2.0 + arc4random_uniform(2*heartSize)) * travelDirection;
CGFloat yDelta = MAX(endPoint.y ,MAX(arc4random_uniform(8*heartSize), heartSize));
CGPoint controlPoint1 = CGPointMake(heartCenterX + xDelta, viewHeight - yDelta);
CGPoint controlPoint2 = CGPointMake(heartCenterX - 2*xDelta, yDelta);

}];
}
- (void)drawRect:(CGRect)rect {
[_strokeColor setStroke];
[_fillColor setFill];
CGFloat drawingPadding = 4.0;
CGFloat curveRadius = floor((CGRectGetWidth(rect) - 2*drawingPadding) / 4.0);
// Creat path
UIBezierPath *heartPath = [UIBezierPath bezierPath];
// Start at bottom heart tip
CGPoint tipLocation = CGPointMake(floor(CGRectGetWidth(rect) / 2.0), CGRectGetHeight(rect) - drawingPadding);
[heartPath moveToPoint:tipLocation];
// Move to top left start of curve
CGPoint topLeftCurveStart = CGPointMake(drawingPadding, floor(CGRectGetHeight(rect) / 2.4));
[heartPath addQuadCurveToPoint:topLeftCurveStart controlPoint:CGPointMake(topLeftCurveStart.x, topLeftCurveStart.y + curveRadius)];
// Create top left curve
