先建個結(jié)構(gòu)體屬性:?
{int i; UIButton *button;}?
創(chuàng)建個按鈕：
button= [[UIButton alloc] initWithFrame:CGRectMake(100,300,20,20)];
[button setImage:[UIImage imageNamed:@"收藏Normal"] forState:UIControlStateNormal];
[button setImage:[UIImage imageNamed:@"收藏Selected"] forState:UIControlStateSelected];
[button addTarget:self action:@selector(change:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button];
實現(xiàn)方法：
-(void)change:(UIButton*)sender {
[button setImage:[UIImage imageNamed:(i%2==0?@"收藏Selected":@"收藏Normal")]forState:UIControlStateNormal];
CAKeyframeAnimation *k = [CAKeyframeAnimation animationWithKeyPath:@"transform.scale"];
k.values=@[@(0.1),@(1.0),@(1.5)];
k.keyTimes=@[@(0.0),@(0.5),@(0.8),@(1.0)];
k.calculationMode=kCAAnimationLinear;
i++;
[button.layer addAnimation:kforKey:@"SHOW"];
}
OK躯畴。
