IOS实现动画的几种简单方式：
1.通过QuadCurveMenuItem实现弹出按钮的效果
NSMutableArray *items = [NSMutableArrayarray];
for (int i = 1; i < 5; i++) {
UIImage *image = [UIImage imageNamed:[NSString stringWithFormat:@"home_h_btn%d.png", (5-i)]];
QuadCurveMenuItem *item = [[QuadCurveMenuItemalloc] initWithImage:image
highlightedImage:image
ContentImage:image
highlightedContentImage:nil];
[items addObject:item];
[item release];
}
CGRect f = CGRectMake(60, 80,33, 33);
HomeQuadCurveMenu *_menu = [[HomeQuadCurveMenualloc] initWithFrame:f menus:items];
_menu.delegate = self;
[_mainPage addSubview:_menu];
[_menu release];
2.通过CABasicAnimation实现平移、旋转、放大
1.旋转
self.view.backgroundColor = [UIColorgreenColor];
CABasicAnimation *ani = [CABasicAnimationanimationWithKeyPath:@"transform.rotation.z"];
ani.fromValue = [NSNumbernumberWithFloat:0];
ani.toValue = [NSNumber numberWithFloat:M_PI*2];
ani.autoreverses = NO;
ani.duration = 10;
ani.repeatCount = 10;
2.平移
CABasicAnimation *ani2 = [CABasicAnimationanimationWithKeyPath:@"transform.translation.x"];
ani2.fromValue = [NSNumber numberWithFloat:0];
ani2.toValue = [NSNumber numberWithFloat:300];
ani2.autoreverses = NO;
ani2.duration = 10;
ani2.repeatCount = 10;
3.放大
CABasicAnimation *ani3 = [CABasicAnimationanimationWithKeyPath:@"transform.scale"];
ani3.fromValue = [NSNumber numberWithFloat:0];
ani3.toValue = [NSNumber numberWithDouble:20];
ani3.autoreverses = NO;
ani3.duration = 10;
ani3.repeatCount = 10;
ani3.speed = 0.5f;
[_rotateImgView.layer addAnimation:ani forKey:@"rotate"];
[_rotateImgView2.layer addAnimation:ani2 forKey:@"animateLayer"];
[_rotateImgView3.layer addAnimation:ani3 forKey:@"sss"];
[_rotateImgView release];
[_rotateImgView2 release];
[_rotateImgView3 release];
3.移动页面位置的动画
void (^animations)(void) = ^{
self.mainPage.transform = CGAffineTransformMakeTranslation(199, 0);};
void (^complete)(BOOL) = ^(BOOL finished) {
self.mainPage.transform = CGAffineTransformMakeTranslation(0, 0);
};
[UIViewanimateWithDuration:2animations:animations completion:complete];
这种动画的书写方式也可以是
[UIViewanimateWithDuration:2animations:^{
self.mainPage.transform = CGAffineTransformMakeTranslation(199, 0);
} completion:^(BOOL finished) {
[UIViewanimateWithDuration:0.2delay:0.1foptions:UIViewAnimationOptionCurveEaseInanimations:^{
self.mainPage.transform = CGAffineTransformMakeTranslation(0, 0);
} completion:^(BOOL finished) {
}];
}];
4.创建简单的动画
[self.view exchangeSubviewAtIndex:0 withSubviewAtIndex:1];
//UIView开始动画，第一个参数是动画的标识，第二个参数附加的应用程序信息用来传递给动画代理消息
[UIView beginAnimations:@"View Flip" context:nil];
//动画持续时间
[UIView setAnimationDuration:1.25];
//设置动画的回调函数，设置后可以使用回调方法
[UIView setAnimationDelegate:self];
//设置动画曲线，控制动画速度
[UIView setAnimationCurve: UIViewAnimationCurveEaseInOut];
//设置动画方式，并指出动画发生的位置
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view cache:YES];
//提交UIView动画
[UIView commitAnimations];
5.自定义cell时可通过以下方法绘制简单的图形
- (void)drawRect:(CGRect)rect
{
CGRect fillRect = CGRectMake(10, 10, 298, cellHeight-20);
float radius = 3;
UIBezierPath *fillPath = [UIBezierPath bezierPathWithRoundedRect:fillRect cornerRadius:radius];
[[UIColor whiteColor] setFill];
[RgbHex2UIColor(237, 237, 237) setStroke];
[fillPath setLineWidth:2.0f];
[fillPath stroke];
[fillPath fill];
}
