Integration
The barrage component mainly provides two Objects：
TUIBarrageButton：Clicking it can bring up the input interface.TUIBarrageDisplayView：Used for displaying barrage messages.In scenarios where barrage messages need to be sent, create a
TUIBarrageButton , which can bring up the input interface when clicked:let barrageButton: TUIBarrageButton = TUIBarrageButton(roomId: xxx)view.addSubview(barrageButton)// layout barrageButton
In scenarios where barrage messages need to be displayed, use
TUIBarrageDisplayView to show the barrage messages:let barrageDisplayView: TUIBarrageDisplayView = TUIBarrageDisplayView(roomId: xxx) view.addSubview(barrageDisplayView)// layout barrageDisplayView
Customize message style
Implement the
createCustomCell delegate function in the TUIBarrageDisplayViewDelegate of TUIBarrageDisplayView, which is used to customize the barrage message style.barrageDisplayView.delegate = selfextension UIViewController: TUIBarrageDisplayViewDelegate {func barrageDisplayView(_ barrageDisplayView: TUIBarrageDisplayView, createCustomCell barrage: TUIBarrage) -> UIView? {// Return custom barrage UI here.}}
Note：
When displaying messages,
TUIBarrageDisplayView will first call the delegate function barrageDisplayView:createCustomCell to obtain the user's custom style for a specific barrage message. If it returns nil, the default barrage style of TUIBarrageDisplayView will be used.InsertCustomMessage
The barrage display component
TUIBarrageDisplayView provides the external interface method insertBarrages for inserting custom messages (in batches). Custom messages are usually used in combination with custom styles to achieve different display effects.// Example: Insert a gift message in the barrage area.let barrage = TUIBarrage() barrage.content = "gift" barrage.user.userId = sender.userId barrage.user.userName = sender.userName barrage.user.avatarUrl = sender.avatarUrl barrage.user.level = sender.level barrage.extInfo["xxx"] = "xxx" barrageDisplayView.insertBarrages(barrage);
Note：
The
extInfo of TUIBarrage is a Map, used for storing custom data.
