第一个项目之六--手势和动画

    前言


    上篇是总算把地铁线给画出来了,虽然没什么美感。嘛,那些可以慢慢改的嘛。
    这篇就来试着给地铁线加些炫酷到不行的功能(其实就是点击动画)。
    <br />

    iOS的事件


    在iOS里面,动作事件有三类:
    1.屏幕触摸事件(点击、长按、拖动等)
    2.加速器动作事件(摇一摇、横向放置等)
    3.远程控制事件(耳机按钮、外置手柄等)
    所有继承了UIResponder的类都可以对事件进行处理。
    这里只对屏幕触摸事件做一个实际应用测试,下面就复制一段对应事件方法:

    <br />

    加上标签


    因为打算对站点添加触摸动作,但是站点都是局部变量,也就是初始化完了之后,我就丢失了联系他们的办法了。那么,此时我们要做的,就是先给每个局部变量加上一个标记,然后再添加一个手势识别,这样我们就可以通过标记来响应触摸事件,来找到对应的站点了。
    首先我要先加两个变量,这是为后面做动画的时候准备的:

    @property (nonatomic, strong) NSMutableArray *array_label_station;
    @property (nonatomic, strong) UIView *view_background_route;
    

    然后先初始化一个单击手势,并将手势添加到站点上面,再设置一个标记:

    UITapGestureRecognizer *gesture_tap_temp1 = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(singleTapAction:)];
    lb_start.tag = 90000;
    lb_start.userInteractionEnabled = YES;
    [lb_start addGestureRecognizer:gesture_tap_temp1];
    

    大概效果最后就是:

    很渣的动画


    手势动作已经做好了,是时候加一下很酷(zha)的动画效果了。
    其实在AlertMessage里面就有用到动画,在这里也是在AlertMessage的动画基础上做一个改动而已。
    首先,要先加一个变量,是用来判断动画是否已经执行了的。

    @property (nonatomic, assign) BOOL isStationsPullAside;
    

    首先对刚才的那个手势方法做个改动,那个showAlertMessage就扔掉了吧,没有用了。我们换一个炫酷很多的:

    - (void)singleTapAction:(UITapGestureRecognizer *)sender{
        [self pullStationsAsideWithTag:sender.self.view.tag];
    }
    
    - (void)pullStationsAsideWithTag:(long)tag{
        float alpha_route = 0;
        float duration_route = 0.2f;
        if(self.isStationsPullAside){
            alpha_route = 1;
            duration_route = 0.4f;
        }
        else{
            alpha_route = 0;
            duration_route = 0.2f;
        }
        [UIView animateWithDuration:duration_route animations:^{
            [self.view_background_route setAlpha:alpha_route];
        }];
        
        for(UILabel *lb_temp in self.array_label_station){
            if(self.isStationsPullAside){
                [UIView animateWithDuration:0.25f animations:^{
                    [lb_temp setFrame:[CommonHandler getVerticaRectlWithSuperView:self.view andYOrigin:lb_temp.frame.origin.y andSize:lb_temp.frame.size]];
                }];
            }else{
                [UIView animateWithDuration:0.25f animations:^{
                    [lb_temp setFrame:CGRectMake(0 - ((lb_temp.frame.size.width / 4) * 3), lb_temp.frame.origin.y, lb_temp.frame.size.width, lb_temp.frame.size.height)];
                }completion:^(BOOL finished){
                    if(lb_temp.tag == tag){
                        [UIView animateWithDuration:0.15f animations:^{
                            [lb_temp setFrame:CGRectMake(0 - ((lb_temp.frame.size.width / 6) * 2), lb_temp.frame.origin.y, lb_temp.frame.size.width, lb_temp.frame.size.height)];
                        }];
                    }
                }];
            }
        }
        self.isStationsPullAside = !self.isStationsPullAside;
    }
    

    这就完成了,先来看看效果,不要抱太多期望,渣到我自己都在偷笑!

    RouteViewAnimate.gif

    动画就是这样,在动画执行完之后,右边有好大一片空白,我们当然是要充分利用这片空白的!我们就在上面添加上附近景点啊、公交路线啊、简介啊、图片啊什么鬼的。
    其实就是添加多一个UIView,在点击之后先设置Alpha为0,然后用动画将Alpha改为1。这样就搞定了:

    - (void)pullStationsAsideWithTag:(long)tag{
        CGSize size_dialog = CGSizeMake(200, self.view.frame.size.height - HEIGHT_NAVIGATIONBAR_STATUSBAR - (GAP_DEFAULT * 4));
    
        float alpha_route = 0;
        float duration_route = 0.2f;
        if(self.isStationsPullAside){
            alpha_route = 1;
            duration_route = 0.4f;
        }
        else{
            self.view_dialog = [[UIView alloc]initWithFrame:CGRectMake(self.view.bounds.size.width / 2 - 55, HEIGHT_NAVIGATIONBAR_STATUSBAR + (GAP_DEFAULT * 2), size_dialog.width, size_dialog.height)];
            self.view_dialog.backgroundColor = [CommonHandler getColorWithRGB:0xf7ef96];
            [self.view_dialog setAlpha:0];
            [self.view addSubview:self.view_dialog];
            alpha_route = 0;
            duration_route = 0.2f;
        }
        [UIView animateWithDuration:duration_route animations:^{
            [self.view_background_route setAlpha:alpha_route];
        }];
        
        for(UILabel *lb_temp in self.array_label_station){
            if(self.isStationsPullAside){
                [UIView animateWithDuration:0.25f animations:^{
                    [self.view_dialog setAlpha:0];
                    [lb_temp setFrame:[CommonHandler getVerticaRectlWithSuperView:self.view andYOrigin:lb_temp.frame.origin.y andSize:lb_temp.frame.size]];
                }completion:^(BOOL finished){
                    [self.view_dialog removeFromSuperview];
                }];
            }else{
                [UIView animateWithDuration:0.25f animations:^{
                    [lb_temp setFrame:CGRectMake(0 - ((lb_temp.frame.size.width / 4) * 3), lb_temp.frame.origin.y, lb_temp.frame.size.width, lb_temp.frame.size.height)];
                }completion:^(BOOL finished){
                    if(lb_temp.tag == tag){
                        [UIView animateWithDuration:0.15f animations:^{
                            [lb_temp setFrame:CGRectMake(0 - ((lb_temp.frame.size.width / 7) * 2), lb_temp.frame.origin.y, lb_temp.frame.size.width, lb_temp.frame.size.height)];
                            [self.view_dialog setAlpha:1];
                        }];
                    }
                }];
            }
        }
        self.isStationsPullAside = !self.isStationsPullAside;
    }
    

    最后贴上效果,至于怎么添加内容嘛,有兴趣的可以自己去尝试!
