进击的UI---------------target/action设计模式&Delegate&手势识别

1.target/action设计模式:

AppDelegate.m

RootViewController.m

 

ClickView.h

ClickView.m

ColorView.h

ColorView.m

RootView.h

RootView.m

ButtonView.h

ButtonView.m

 

2.delegate设计模式(代理):

AppDelegate.m

RootViewController.m

RootView.h:

RootView.m:

colorView.h

colorView.m

clickView.h

clickView.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)

1⃣️: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;

2⃣️: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                      是轻拍⼿手势识别器,能识别轻拍操作.
//    UILongPressGestureRecognizer                长按⼿手势识别器,能识别⻓长按操作.
//    UIRotationGestureRecognizer                   旋转⼿手势识别器,能识别旋转操作.
//    UIPinchGestureRecognizer                      捏合⼿手势识别器,能识别捏合操作.
//    UIPanGestureRecognizer                        平移⼿手势识别器,能识别拖拽操作.
//    UISwipeGestureRecognizer                      轻扫⼿手势识别器,能识别拖拽操作.
//    UIScreenEdgePanGestureRecognizer        屏幕边缘轻扫识别器,ios7中新增的⼿手势.
