写几个动画，tableview，button动画

tableview 扇页动画

CATransform3Drotation;

rotation =CATransform3DMakeRotation( (90.0*M_PI)/180,0.0,0.7,0.4);

rotation.m34=1.0/ -600;

cell.layer.shadowColor= [[UIColorblackColor]CGColor];

cell.layer.shadowOffset=CGSizeMake(10,10);

cell.alpha=0;

cell.layer.transform= rotation;

cell.layer.anchorPoint=CGPointMake(0,0.5);

[UIViewbeginAnimations:@"rotation"context:NULL];

[UIViewsetAnimationDuration:0.8];

cell.layer.transform=CATransform3DIdentity;

cell.alpha=1;

cell.layer.shadowOffset=CGSizeMake(0,0);

[UIViewcommitAnimations];

tableview偏移动画

cell.alpha=0.5;

CGAffineTransformtransformScale =CGAffineTransformMakeScale(0.3,0.8);

CGAffineTransformtransformTranslate =CGAffineTransformMakeTranslation(0.5,0.6);

cell.transform=CGAffineTransformConcat(transformScale, transformTranslate);

[tableViewbringSubviewToFront:cell];

[UIViewanimateWithDuration:.4f

delay:0

options:UIViewAnimationOptionAllowUserInteraction

animations:^{

cell.alpha=1;

//清空transform

cell.transform=CGAffineTransformIdentity;

}completion:nil];

---

按钮点击动画

//点击动画

[UIViewbeginAnimations:nilcontext:nil];

[UIViewsetAnimationDuration:0.20];

[UIViewsetAnimationDelegate:self];

//    slideBg.frame = btn.frame;

[UIViewcommitAnimations];

CAKeyframeAnimation* animation;

animation = [CAKeyframeAnimationanimationWithKeyPath:@"transform"];

animation.duration=0.5;

animation.delegate=self;

animation.removedOnCompletion=YES;

animation.fillMode=kCAFillModeForwards;

NSMutableArray*values = [NSMutableArrayarray];

[valuesaddObject:[NSValuevalueWithCATransform3D:CATransform3DMakeScale(1.0,1.0,1.0)]];

[valuesaddObject:[NSValuevalueWithCATransform3D:CATransform3DMakeScale(1.2,1.2,1.0)]];

//[values addObject:[NSValue valueWithCATransform3D:CATransform3DMakeScale(1.5, 1.5, 0.9)]];

[valuesaddObject:[NSValuevalueWithCATransform3D:CATransform3DMakeScale(1.0,1.0,1.0)]];

animation.values= values;

[按钮.layeraddAnimation:animationforKey:nil];

tableview点击某一行放大cell高度

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {

if(该indexPath被选中) {

return 60 * 2.0;

}

return 60;

}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

[tableView deselectRowAtIndexPath:indexPath animated:TRUE];

//获取当前indexPath并判断对应的Cell是否被选中

//最神奇的地方！！

[tableView beginUpdates];

[tableView endUpdates];

}
