最近一直在做直播方面的事情，在做弹幕的时候遇到了一些问题。后来找到了一个相当不错的解决方法，用野狗的SDK，😂。废话就不多说了，大家看下效果～
整体的项目结构：
下面简单讲解下实现的过程：
初始化：
_wilddog = [[Wilddog alloc] initWithUrl:kWilddogUrl];
_snaps = [[NSMutableArray alloc] init];
_originFrame = self.view.frame;
[self.wilddog observeEventType:WEventTypeChildAdded withBlock:^(WDataSnapshot *snapshot) {
[self sendLabel:snapshot];
[self.snaps addObject:snapshot];
}];
发送弹幕：
- (UILabel *)sendLabel:(WDataSnapshot *)snapshot
{
float top = (arc4random()% (int)self.view.frame.size.height)-100;
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(self.view.frame.size.width, top, 100, 30)];
label.textColor = [UIColor colorWithRed:arc4random()%255/255.f green:arc4random()%255/255.f blue:arc4random()%255/255.f alpha:1];
label.text = snapshot.value;
[UIView animateWithDuration:7 animations:^{
label.frame = CGRectMake(-label.frame.size.width, top, 100, 30);
}completion:^(BOOL finished){
[label removeFromSuperview];
}];
[self.view addSubview:label];
return label;
}
