ios - 条件下在其他情况下的预期表达

Question

我有以下代码来确定游戏是否应该移动到下一个级别。最后的else if and else条件导致两个错误。 “期望的表达式”和“期望的标识符”。如果我注释掉这些条件，代码可以正常编译。不确定我缺少什么。任何帮助将不胜感激。

- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
    for (UITouch *touch in touches) {
        SKNode *n = [self nodeAtPoint: [touch locationInNode:self]];
        if (n !=self && [n.name isEqual:@"restartLabel"] && _gameLevel == 0){
            [[self childNodeWithName:@"restartLabel"] removeFromParent];
            [[self childNodeWithName:@"winLoseLabel"] removeFromParent];
            SKTransition *reveal = [SKTransition flipHorizontalWithDuration:0.5];
            SKScene * myScene = [[MyScene alloc] initWithSize:self.size];
            [self.view presentScene:myScene transition: reveal];
            return;
        }
    else if (n !=self && [n.name isEqual:@"nextLevelLabel"] && _gameLevel == 1)
        {
            [[self childNodeWithName:@"nextLevelLabel"] removeFromParent];
            [[self childNodeWithName:@"winLoseLabel"] removeFromParent];
            SKTransition *reveal = [SKTransition flipHorizontalWithDuration:0.5];
            SKScene * myScene2 = [[MyScene2 alloc] initWithSize:self.size];
            [self.view presentScene:myScene2 transition: reveal];
            return;
        }
    }
    else if (n !=self && [n.name isEqual:@"nextLevelLabel"] && _gameLevel == 2)
        {
            [[self childNodeWithName:@"nextLevelLabel"] removeFromParent];
            [[self childNodeWithName:@"winLoseLabel"] removeFromParent];
            SKTransition *reveal = [SKTransition flipHorizontalWithDuration:0.5];
            SKScene * myScene3 = [[MyScene3 alloc] initWithSize:self.size];
            [self.view presentScene:myScene3 transition: reveal];
            return;
        }
}
    else
        {            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"End of the Road" message:@"You reached the end of the game. More levels coming soon!" delegate:self cancelButtonTitle:@"Ok"  nil]
            [alert show];
        }
    @end

else if (n !=self && [n.name isEqual:@"nextLevelLabel"] && _gameLevel == 1)
    {
        [[self childNodeWithName:@"nextLevelLabel"] removeFromParent];
        [[self childNodeWithName:@"winLoseLabel"] removeFromParent];
        SKTransition *reveal = [SKTransition flipHorizontalWithDuration:0.5];
        SKScene * myScene2 = [[MyScene2 alloc] initWithSize:self.size];
        [self.view presentScene:myScene2 transition: reveal];
        return;
    }
