效果图：
1、定义属性
@property (nonatomic, strong) UIView *transformView;//发生变换的试图 @property (nonatomic, strong) UIView *backGroundView;//发生变换试图的父试图 @property (nonatomic, strong) UITableView *titleTableView; @property (nonatomic, strong) NSArray *dataSourceAry;//数据源数组
2、实现代码
-(void)poppingViewWithTransform:(NSString *)transformStr{
[self.view addSubview:self.backGroundView];
self.transformView.frame = CGRectMake(SCWidth/2-100, 200, 200, 200);
if ([transformStr isEqualToString:@"缩放变换"]) {
//很简单的变换效果，200，为Y轴从下往上平移，相反-200 是从上往下平移
self.transformView.transform = CGAffineTransformMakeScale(0.0, 0.0);
[UIView animateWithDuration:0.5 animations:^{
self.transformView.transform = CGAffineTransformMakeScale(1.0, 1.0);
}];
}else if([transformStr isEqualToString:@"平移变换"]){
//很简单的变换效果，200，为Y轴从下往上平移，相反-200 是从上往下平移，X轴变换同理
self.transformView.transform = CGAffineTransformMakeTranslation(0, -200);
[UIView animateWithDuration:0.5 animations:^{
self.transformView.transform = CGAffineTransformMakeTranslation(0,0);
}];
}else if([transformStr isEqualToString:@"翻转变换"]){
//下面注释的代码，最后Z轴改成一个数字，例12，可以实现旋转变换
//self.transformView.layer.transform = CATransform3DMakeRotation(12, 1, 1, 0);
self.transformView.layer.transform = [self firstStep];
[UIView animateWithDuration:0.5 animations:^{
self.transformView.layer.transform = CATransform3DMakeRotation(0, 1, 0, 0);
}];
}else if([transformStr isEqualToString:@"旋转变换"]){
//具体效果可以更改 M_PI_4 角度来实现
self.transformView.transform = CGAffineTransformMake(( cos(M_PI_4) ), ( sin(M_PI_4) ), -( sin(M_PI_4) ), (cos(M_PI_4) ), 0, 0);
[UIView animateWithDuration:0.5 animations:^{
self.transformView.transform = CGAffineTransformMake(( cos(M_PI) ), ( sin(M_PI) ), -( sin(M_PI) ), (cos(M_PI) ), 0, 0);
}];
}else if([transformStr isEqualToString:@"剪切变换"]){
//使用仿射基础方法CGAffineTransformMake,设置x和y都为0.5的斜切
//可以试着把第一个1换成0.5，看看效果
//可以试着把第二个1换成0.5，看看效果
self.transformView.transform = CGAffineTransformMake(1,0.5,0.5,1,0,0);
[UIView animateWithDuration:0.5 animations:^{
self.transformView.transform = CGAffineTransformMake(1,0,0,1,0,0);
}];
}
self.transformView.layer.cornerRadius = 7;
self.transformView.layer.masksToBounds = YES;
[self.backGroundView addSubview:self.transformView];
」
其中，翻转变化用到这个：
-(CATransform3D)firstStep{
//让transform1为单位矩阵
CATransform3D transform1 = CATransform3DIdentity;
//z轴纵深的3D效果和CATransform3DRotate配合使用才能看出效果
//m34很重要
transform1.m34 = 1.0/-100;
//x和y都缩小为原来的0.9，z不变
transform1 = CATransform3DScale(transform1, 0.9, 0.9, 1);
//绕x轴向内旋转15度
transform1 = CATransform3DRotate(transform1,15.0f * M_PI/180.0f, 1, 0, 0);
return transform1;
