1.target/action设计模式:
AppDelegate.m
RootViewController.m
ClickView.h
ClickView.m
ColorView.h

2.delegate设计模式(代理):
AppDelegate.m

3.UIImageView:
self.backgroundColor = [UIColor colorWithRed:arc4random()%2/1.0 green:arc4random()%2/1.0 blue:arc4random()%2/1.0 alpha:1];
self.mv = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"1.jpg"]];
self.mv.frame = CGRectMake(0, 0, self.frame.size.width, self.frame.size.height);
[self addSubview:_mv];
4.手势识别器(Gesture Recognizor)
1??:手势识别器有7个子类 分别是识别轻拍手势,平移手势,轻扫手势,缩放手势,旋转手势,长按手势,以及屏幕边界平移手势,一旦指定的手势被识别,就可以执行自己定义好的操作;
2??:代码
// 轻拍/点击
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tapAction:)];// 手势添加到相应的控件上添加手势
tap.numberOfTapsRequired = 1;// 连续点击1下,点击数
// tap.numberOfTouchesRequired = 2;// 手指数(alt + 点击)
self.fv.mv.userInteractionEnabled = YES;
[self.fv.mv addGestureRecognizer:tap];
_flag = YES;
// 长按
UILongPressGestureRecognizer *press = [[UILongPressGestureRecognizer alloc]initWithTarget:self action:@selector(pressAction:)];
[self.fv.mv addGestureRecognizer:press];
press.minimumPressDuration = 1; // 最短长按时间
// 捏合
UIPinchGestureRecognizer *pinch = [[UIPinchGestureRecognizer alloc]initWithTarget:self action:@selector(pinchAction:)];
[self.fv.mv addGestureRecognizer:pinch];
// 旋转
UIRotationGestureRecognizer *rotation = [[UIRotationGestureRecognizer alloc]initWithTarget:self action:@selector(rotationAction:)];
[self.fv.mv addGestureRecognizer:rotation];
// 平移
UIPanGestureRecognizer *pan = [[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(panAction:)];
[self.fv.mv addGestureRecognizer:pan];
// 轻扫
UISwipeGestureRecognizer *swipe = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(swipeAction:)];
[self.fv.mv addGestureRecognizer:swipe];
// 屏幕边缘轻扫
UIScreenEdgePanGestureRecognizer *sep = [[UIScreenEdgePanGestureRecognizer alloc]initWithTarget:self action:@selector(sepAction:)];
[self.fv.mv addGestureRecognizer:sep];
//用户交互打开;UIImageView的用户交互默认是关闭的,需要打开才能正常使用;
// UITapGestureRecognizer 是轻拍?手势识别器,能识别轻拍操作.
// UILongPressGestureRecognizer 长按?手势识别器,能识别?长按操作.
// UIRotationGestureRecognizer 旋转?手势识别器,能识别旋转操作.
// UIPinchGestureRecognizer 捏合?手势识别器,能识别捏合操作.
// UIPanGestureRecognizer 平移?手势识别器,能识别拖拽操作.
// UISwipeGestureRecognizer 轻扫?手势识别器,能识别拖拽操作.
// UIScreenEdgePanGestureRecognizer 屏幕边缘轻扫识别器,ios7中新增的?手势.
