usage

• in the need to use the function of local barrage rendering

 #import “KYBarrageKit”

• create a KYBarrageManager *manager object, and the view add that you want to add a barrage of animation view, as shown below:

@interface ViewController ()@property (strong, nonatomic) KYBarrageManager *manager;@end@implementation ViewController- (void)viewDidLoad {  [super viewDidLoad];  // Do any additional setup after loading the view, typically from a nib.   self.view.backgroundColor = [UIColor whiteColor];    _manager = [KYBarrageManager manager];    _manager.bindingView = self.view;    _manager.scrollSpeed = 30;         _manager.refreshInterval = 1.0;  }

• send a barrage

int a = arc4random() % 100000;    NSString *str = [NSString stringWithFormat:@"I'm coming %d ",a];        NSMutableAttributedString *attr = [[NSMutableAttributedString alloc] initWithString:str];    [attr addAttribute:NSForegroundColorAttributeName value:RandomColor() range:NSMakeRange(0, str.length)];        KYBarrageModel *m = [[KYBarrageModel alloc] initWithBarrageContent:attr];    [_manager showBarrageWithDataSource:m]; // Scroll Barrage 

• set up a barrage of display area, support four direction, the default for the entire display area KYBarrageDisplayLocationTypeDefault

Global setting

_manager.displayLocation = KYBarrageDisplayLocationTypeTop;  

Or when the sub set barrage

   KYBarrageModel *m = [[KYBarrageModel alloc] initWithBarrageContent:attr];    m.displayLocation       = _manager. KYBarrageDisplayLocationTypeTop; 

Support for the display area of the corresponding NSInteger enumeration:

• set the barrage position display support four direction.

Global setting

_manager.scrollDirection = KYBarrageScrollDirectRightToLeft;   

Or when the sub set barrage

   KYBarrageModel *m = [[KYBarrageModel alloc] initWithBarrageContent:attr];    m.direction       = _manager.scrollDirection; 

Support for the enumeration of NSInteger in four directions:

• active pull data set barrage barrage, commissioned by KYBarrageManagerDelegate, call the -delegate barrageManagerDataSource data

Set proxy，Open Access Initiative barrage

 _manager.delegate = self; [_manager startScroll]; //Open Access Initiative barrage

Calling method

- (id)barrageManagerDataSource {        int a = arc4random() % 10000;    NSString *str = [NSString stringWithFormat:@"%d digg",a];        NSMutableAttributedString *attr = [[NSMutableAttributedString alloc] initWithString:str];    [attr addAttribute:NSForegroundColorAttributeName value:RandomColor() range:NSMakeRange(0, str.length)];        KYBarrageModel *m = [[KYBarrageModel alloc] initWithBarrageContent:attr];    m.displayLocation = _manager.displayLocation;    m.direction       = _manager.scrollDirection;    m.barrageType = KYBarrageDisplayTypeImage;    m.object = [UIImage imageNamed:[NSString stringWithFormat:@"digg_%d",arc4random() % 10]];    return m;}

• set the clear barrage.

[_manager closeBarrage];

• set the barrage of pause and recovery.

    // 1. On the screen the barrage is suspended, and stop acquiring new barrage    // 2. The current barrage on the screen to start rolling, and to obtain a new barrage   [_manager pauseScroll];

• type setting barrage currently supports plain text and graphics KYBarrageDisplayTypeDefault KYBarrageDisplayTypeImage, can customize other types of KYBarrageScene.

m.barrageType = KYBarrageDisplayTypeImage;

Other

The click event support barrage

If a barrage of type KYBarrageDisplayTypeImage barrage, please rewrite the ViewController touchesBegan method

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {    UITouch *touch = [touches anyObject];    CGPoint touchPoint = [touch locationInView:self.view];    [[_manager barrageScenes] enumerateObjectsUsingBlock:^(BarrageScene * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {        if ([obj.layer.presentationLayer hitTest:touchPoint]) {           /* if barrage's type is ` `KYBarrageDisplayTypeImage` `, add your code here*/            NSLog(@"message = %@",obj.model.message.string);        }    }];}

Such as click inside the DEMO barrage, barrage pause 3S after rolling, can also be extended to other events, as shown below:
