代码：
//insert to correct position according datetime var insertedRowIdx:Int = 0 var hasInserted:Bool = false for (curIdx, curMessage) in msgTVC.messageList.enumerate() { // print("[\(curIdx)] newMessage.timestamp=\(newMessage.timestamp), curMessage.timestamp=\(curMessage.timestamp), newMessage.text=\(newMessage.text)") if newMessage.timestamp < curMessage.timestamp { msgTVC.messageList.insert(newMessage, atIndex: curIdx) insertedRowIdx = curIdx hasInserted = true break } } if !hasInserted { msgTVC.messageList.append(newMessage) insertedRowIdx = msgTVC.messageList.count – 1 hasInserted = true } //update timestamp string if insertedRowIdx > 0 { let prevMessage = msgTVC.messageList[insertedRowIdx – 1] newMessage.timestampStr = generateTimestampStr(newMessage.timestamp, prevTimestamp: prevMessage.timestamp) } else { newMessage.timestampStr = generateTimestampStr(newMessage.timestamp, prevTimestamp: nil) } // print("insertedRowIdx=\(insertedRowIdx)") let curRealRowNum = msgTVC.messageTableView.numberOfRowsInSection(0) //insert row let insertedRowIndexPath:NSIndexPath = NSIndexPath(forRow: insertedRowIdx, inSection: 0) // msgTVC.messageTableView.beginUpdates() msgTVC.messageTableView.insertRowsAtIndexPaths([insertedRowIndexPath], withRowAnimation: UITableViewRowAnimation.Bottom) // msgTVC.messageTableView.endUpdates() //here consider inserted to index=0, is get history message //-> should not scroll upside if isCurrentShowingVc(msgTVC) && (insertedRowIdx != 0){ //only when current vc, then scroll to that row msgTVC.messageTableView.scrollToRowAtIndexPath(insertedRowIndexPath, atScrollPosition: UITableViewScrollPosition.Bottom, animated: false) } |
中的：
insertRowsAtIndexPaths
又挂了：
Terminating app due to uncaught exception ‘NSInternalInconsistencyException’, reason: ‘attempt to insert row 16 into section 0, but there are only 0 rows in section 0 after the update’
以及：
enqueued from NSOperationQueue
如图：
搜：
tableview NSInternalInconsistencyException enqueued from NSOperationQueue
insertRowsAtIndexPaths NSInternalInconsistencyException
改为：
msgTVC.messageTableView.beginUpdates() //insert to correct position according datetime var insertedRowIdx:Int = 0 var hasInserted:Bool = false for (curIdx, curMessage) in msgTVC.messageList.enumerate() { // print("[\(curIdx)] newMessage.timestamp=\(newMessage.timestamp), curMessage.timestamp=\(curMessage.timestamp), newMessage.text=\(newMessage.text)") if newMessage.timestamp < curMessage.timestamp { msgTVC.messageList.insert(newMessage, atIndex: curIdx) insertedRowIdx = curIdx hasInserted = true break } } if !hasInserted { msgTVC.messageList.append(newMessage) insertedRowIdx = msgTVC.messageList.count – 1 hasInserted = true } //update timestamp string if insertedRowIdx > 0 { let prevMessage = msgTVC.messageList[insertedRowIdx – 1] newMessage.timestampStr = generateTimestampStr(newMessage.timestamp, prevTimestamp: prevMessage.timestamp) } else { newMessage.timestampStr = generateTimestampStr(newMessage.timestamp, prevTimestamp: nil) } // print("insertedRowIdx=\(insertedRowIdx)") //insert row let insertedRowIndexPath:NSIndexPath = NSIndexPath(forRow: insertedRowIdx, inSection: 0) msgTVC.messageTableView.insertRowsAtIndexPaths([insertedRowIndexPath], withRowAnimation: UITableViewRowAnimation.Bottom) msgTVC.messageTableView.endUpdates() |
还是不行。
搜：
ios numberofrowsinsection not called
ios numberofrowsinsection not correct
ios numberofrowsinsection not same with list count
最后改为：
//insert to correct position according datetime var insertedRowIdx:Int = 0 var hasInserted:Bool = false for (curIdx, curMessage) in msgTVC.messageList.enumerate() { // print("[\(curIdx)] newMessage.timestamp=\(newMessage.timestamp), curMessage.timestamp=\(curMessage.timestamp), newMessage.text=\(newMessage.text)") if newMessage.timestamp < curMessage.timestamp { msgTVC.messageList.insert(newMessage, atIndex: curIdx) insertedRowIdx = curIdx hasInserted = true break } } if !hasInserted { msgTVC.messageList.append(newMessage) insertedRowIdx = msgTVC.messageList.count – 1 hasInserted = true } //update timestamp string if insertedRowIdx > 0 { let prevMessage = msgTVC.messageList[insertedRowIdx – 1] newMessage.timestampStr = generateTimestampStr(newMessage.timestamp, prevTimestamp: prevMessage.timestamp) } else { newMessage.timestampStr = generateTimestampStr(newMessage.timestamp, prevTimestamp: nil) } // print("insertedRowIdx=\(insertedRowIdx)") let curRealRowNum = msgTVC.messageTableView.numberOfRowsInSection(0) let curRealRowMaxIdx = curRealRowNum – 1 if insertedRowIdx < curRealRowMaxIdx { //insert row msgTVC.messageTableView.beginUpdates() let insertedRowIndexPath:NSIndexPath = NSIndexPath(forRow: insertedRowIdx, inSection: 0) msgTVC.messageTableView.insertRowsAtIndexPaths([insertedRowIndexPath], withRowAnimation: UITableViewRowAnimation.Bottom) msgTVC.messageTableView.endUpdates() //here consider inserted to index=0, is get history message //-> should not scroll upside if isCurrentShowingVc(msgTVC) && (insertedRowIdx != 0){ //only when current vc, then scroll to that row msgTVC.messageTableView.scrollToRowAtIndexPath(insertedRowIndexPath, atScrollPosition: UITableViewScrollPosition.Bottom, animated: false) } } |
基本确保了，insertRowsAtIndexPaths不会挂了。。。
