蓝懿IOS利用所学的控件做小游戏

   - (IBAction)upAction:(UIButton *)sender {

//    _ib.center=CGPointMake(_ib.center.x, _ib.center.y-10);

//}

//- (IBAction)leftAction:(UIButton *)sender {

//    _ib.center=CGPointMake(_ib.center.x-10, _ib.center.y);

//}

//- (IBAction)downAction:(UIButton *)sender {

//    _ib.center=CGPointMake(_ib.center.x, _ib.center.y+10);

//}

//- (IBAction)rightAction:(UIButton *)sender {

//    _ib.center=CGPointMake(_ib.center.x+10, _ib.center.y);

//}

//

//- (void)viewDidLoad {

//    [super viewDidLoad];

//    

//    _ib=[[UIImageView alloc]initWithFrame:CGRectMake(10, 100, 100, 100)];

//    _ib.image=[UIImage imageNamed:@"555.jpg"];

//    [self.view addSubview:_ib];

//   }

  2，while循环来实现显示卖出多少苹果，还剩多少苹果。

//- (void)viewDidLoad {

//    [super viewDidLoad];

//    

//    

//    int apples=100;

//    int selleapples=0;

//    while (selleapples<100) {

//        //selleapples+1,自身的值不会变

//        NSLog(@"卖到第%d个水果",selleapples+1);

//        //selleapples++和selleapple+的意义不同，前者是把自身的值加1，自身先取0然后加1变成1.

//        selleapples++;

//        //  selleapples就是上面他自身＋＋之后的结果1.

//        NSLog(@"卖掉了%d个果，还有%d个",selleapples,apples-selleapples);

//        

//    }

//    

  3，通过所学荣和知识点编写晓得游戏，功能实现包括，通过按键控制一个物体，从屏幕的下方移动到屏幕的上方，中间基础到横排移动的障碍物后则失败。

//- (void)viewDidLoad {

//    [super viewDidLoad];

//    _kk=10;

//    _kk2=15;

//    _kk3=20;

//    

//    

//    _iv=[[UIImageView alloc]initWithFrame:CGRectMake(330, 80, 100, 100)];

//    _iv.image=[UIImage imageNamed:@"02.jpg"];

//    _iv.backgroundColor=[UIColor brownColor];

//    [self.view addSubview:_iv];

//    

//    _iv2=[[UIImageView alloc]initWithFrame:CGRectMake(330, 240, 100, 100)];

//    _iv2.image=[UIImage imageNamed:@"03.jpeg"];

//    [self.view addSubview:_iv2];

//    _iv3=[[UIImageView alloc]initWithFrame:CGRectMake(330, 390, 100, 100)];

//    _iv3.image=[UIImage imageNamed:@"01.jpg"];

//    [self.view addSubview:_iv3];

//    

//   _time1=[NSTimer scheduledTimerWithTimeInterval:.1 target:self selector:@selector(move1) userInfo:nil repeats:YES];

//    

//

//}

//-(void)move1{

//

//    

//    _iv.center=CGPointMake(_iv.center.x-_kk, _iv.center.y);

//        

//    if (_iv.center.x>380||_iv.center.x<0) {

//        _kk=-_kk;

//        

//    }

//    

//    _iv2.center=CGPointMake(_iv2.center.x-_kk2, _iv2.center.y);

//    

//    if (_iv2.center.x>380||_iv2.center.x<0) {

//        _kk2=-_kk2;

//        

//    }

//    

//    _iv3.center=CGPointMake(_iv3.center.x-_kk3, _iv3.center.y);

//    

//    if (_iv3.center.x>380||_iv3.center.x<0) {

//        _kk3=-_kk3;

//        

//    }

//}
