Question

我正在写一个游戏。在攻击者杀死一名士兵之后，将会显示一个丢弃的UIImageView说经验+ 1。

现在，当我杀死第一名士兵时动画显示正确，但是当杀死第二名士兵时，不显示。

动画代码，方法名称为showGainXPAnimationAfterKillSoldier。

    imgGainXPAfterKillSoldier.hidden = FALSE;
    [imgGainXPAfterKillSoldier.layer removeAllAnimations];
    imgGainXPAfterKillSoldier.frame = CGRectMake(140, 220, 53, 19);
    // a loop to show animation.
    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationBeginsFromCurrentState:YES];
    [UIView setAnimationDuration:1.5];
    //imgGainXPAfterKillSoldier.frame = CGRectMake(100, 200, 53, 19);
    CGAffineTransform transform = CGAffineTransformMakeTranslation(-112, 215);
    imgGainXPAfterKillSoldier.transform = transform;
    //imgGainXPAfterKillSoldier.alpha = 0.0f;
    [UIView commitAnimations];

调用动画代码，

    if (killedSoldierCount>0) {
    // add imgview to show gained XP.
    if (imgGainXPAfterKillSoldier) {
        MWLog(@"remove it!");
        [imgGainXPAfterKillSoldier.layer removeAllAnimations];
        [imgGainXPAfterKillSoldier removeFromSuperview];

    }
    imgGainXPAfterKillSoldier.frame = CGRectMake(140, 220, 53, 19);
    imgGainXPAfterKillSoldier.hidden = TRUE;
    //imgGainXPAfterKillSoldier.alpha = 1.0f;
    [self.view addSubview:imgGainXPAfterKillSoldier];

    switch (killedSoldierCount) {
        case 1:
            // show add experience animation after kill soldier.
            MWLog(@"kill a soldier, show XP+1 animation.");
            [self showGainXPAnimationAfterKillSoldier:1];
            break;

有什么问题？提前谢谢！

现在问题已解决。每次我想要动画，我都会创建一个新的UIImageView来做到这一点。不重复使用xib文件中定义的UIImageView。

UIImageView的动画只运行一次
