UITabelview的刪除，UITabelview刪除

self.tableView?.deleteRowsAtIndexPaths([indexPath,indexPath1], withRowAnimation: .Left)        //title是資料來源        self.titles.removeAtIndex(0)        self.titles.removeAtIndex(0)

2016-07-30 21:44:26.613 UITableViewLearn[14976:575144] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 0.  The number of rows contained in an existing section after the update (4) must be equal to the number of rows contained in that section before the update (4), plus or minus the number of rows inserted or deleted from that section (0 inserted, 2 deleted) and plus or minus the number of rows moved into or out of that section (0 moved in, 0 moved out).'

UIKit在調用deleteRowsAtIndexPaths時，會判斷前後資料來源的一致性，如果前後不一致，會拋出異常。然而只是判斷cell的個數是否一致。如果刪除了第0、1列的資料，然後刪除第2、3列的cell，也不會報錯。

    let indexPath = NSIndexPath.init(forRow: 2, inSection: 0)    let indexPath1 = NSIndexPath.init(forRow: 3, inSection: 0)    //title是資料來源    self.titles.removeAtIndex(0)    self.titles.removeAtIndex(0)    self.tableView?.deleteRowsAtIndexPaths([indexPath,indexPath1], withRowAnimation: .Left)

上面的不會報錯
