仿支付宝芝麻信用仪表盘效果

一、主要思路

1.圆环上绿点的旋转
2.分数值及提示语的变化
3.背景色的变化

二、程序实现

一. 自定义ZLDashboardView仪表盘文件:

根据跃动数字, 确定百分比, 现在的跳动数字 ----> 背景颜色变化

.h 文件里公开跃动数字刷新方法:

@property (nonatomic, copy) void(^TimerBlock)(NSInteger);
/**
 *  跃动数字刷新
 *
 */
- (void)refreshJumpNOFromNO:(NSString *)startNO toNO:(NSString *)toNO;

.m 文件

自定义Lift cycle

#pragma mark - Life cycle
- (instancetype)initWithFrame:(CGRect)frame {    
    self = [super initWithFrame:frame];    
    if (self) {        
        self.backgroundColor = [UIColor clearColor];        
        self.circelRadius = self.frame.size.width - 10.f;        
        self.lineWidth = 2.f;        
        self.startAngle = -200.f;        
        self.endAngle = 20.f;        
        // 尺寸需根据图片进行调整
        self.bgImageView.frame = CGRectMake(6, 6, self.circelRadius, self.circelRadius * 2 / 3);          self.bgImageView.backgroundColor = [UIColor clearColor];
        [self addSubview:self.bgImageView];       
        // 添加圆框
        [self setupCircleBg];        
        // 光标
        [self setupMarkerImageView];        
        // 添加跃动数字 及 提示语
        [self setupJumpNOView];
    }    
    return self;
}

2.添加圆框

- (void)setupCircleBg {    
    // 圆形路径
    UIBezierPath *path = [UIBezierPath bezierPathWithArcCenter:CGPointMake(self.width / 2, self.height / 2)
                                                        radius:(self.circelRadius - self.lineWidth) / 2
                                                    startAngle:degreesToRadians(self.startAngle)
                                                      endAngle:degreesToRadians(self.endAngle)
                                                     clockwise:YES];    
    // 底色
    self.bottomLayer = [CAShapeLayer layer];    
    self.bottomLayer.frame = self.bounds;    
    self.bottomLayer.fillColor = [[UIColor clearColor] CGColor];    
    self.bottomLayer.strokeColor = [[UIColor  colorWithRed:206.f / 256.f green:241.f / 256.f blue:227.f alpha:1.f] CGColor];    
    self.bottomLayer.opacity = 0.5;    
    self.bottomLayer.lineCap = kCALineCapRound;    
    self.bottomLayer.lineWidth = self.lineWidth;    
    self.bottomLayer.path = [path CGPath];
    [self.layer addSublayer:self.bottomLayer];
// 240 是用整个弧度的角度之和 |-200| + 20 = 220
//    [self createAnimationWithStartAngle:degreesToRadians(self.startAngle)
//                               endAngle:degreesToRadians(self.startAngle + 220 * 1)];
    }

3.设置光标

- (void)setupMarkerImageView {    
    if (_markerImageView) {        
        return;
    }
    _markerImageView = [[UIImageView alloc] init];
    _markerImageView.backgroundColor = [UIColor clearColor];
    _markerImageView.layer.backgroundColor = [UIColor greenColor].CGColor;
    _markerImageView.layer.shadowColor = [UIColor whiteColor].CGColor;
    _markerImageView.layer.shadowOffset = CGSizeMake(0, 0);
    _markerImageView.layer.shadowRadius = kMarkerRadius*0.5;
    _markerImageView.layer.shadowOpacity = 1;
    _markerImageView.layer.masksToBounds = NO;    
    self.markerImageView.layer.cornerRadius = self.markerImageView.frame.size.height / 2;
    [self addSubview:self.markerImageView];
    _markerImageView.frame = CGRectMake(-100, self.height, kMarkerRadius, kMarkerRadius);
}

4.添加跳跃文字及提示语

- (void)setupJumpNOView {    
    if (_showLable) {        
        return;
    }    
    CGFloat width = self.circelRadius / 2 + 50;    
    CGFloat height = self.circelRadius / 2 - 50;    
    CGFloat xPixel = self.bgImageView.left + (self.bgImageView.width - width)*0.5;//self.circelRadius / 4;
    CGFloat yPixel = self.circelRadius / 4;    
    CGRect labelFrame = CGRectMake(xPixel, yPixel, width, height);
    _showLable = [[UILabel alloc] initWithFrame:labelFrame];
    _showLable.backgroundColor = [UIColor clearColor];
    _showLable.textColor = [UIColor greenColor];
    _showLable.textAlignment = NSTextAlignmentCenter;
    _showLable.font = [UIFont systemFontOfSize:100.f];
    _showLable.text = [NSString stringWithFormat:@"%ld",jumpCurrentNO];
    [self addSubview:_showLable];    // 提示语
    _markedLabel = [[UILabel alloc] initWithFrame:CGRectMake(xPixel, CGRectGetMaxY(_showLable.frame), width, 30)];
    _markedLabel.backgroundColor = [UIColor clearColor];
    _markedLabel.textColor = [UIColor greenColor];
    _markedLabel.textAlignment = NSTextAlignmentCenter;
    _markedLabel.font = [UIFont systemFontOfSize:20.f];
    _markedLabel.text = @"营养良好";
    [self addSubview:_markedLabel];
}

5.动画相关

#pragma mark - Animation
- (void)createAnimationWithStartAngle:(CGFloat)startAngle endAngle:(CGFloat)endAngle { // 光标动画
 
    //启动定时器
    [_fastTimer setFireDate:[NSDate distantPast]];    // 设置动画属性
    CAKeyframeAnimation *pathAnimation = [CAKeyframeAnimation animationWithKeyPath:@"position"];
    pathAnimation.calculationMode = kCAAnimationPaced;
    pathAnimation.fillMode = kCAFillModeForwards;
    pathAnimation.removedOnCompletion = NO;
    pathAnimation.duration = _percent * kTimerInterval;
    pathAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut];
    pathAnimation.repeatCount = 1;    // 设置动画路径
    CGMutablePathRef path = CGPathCreateMutable();    CGPathAddArc(path, NULL, self.width / 2, self.height / 2, (self.circelRadius - kMarkerRadius / 2) / 2, startAngle, endAngle, 0);
    pathAnimation.path = path;    CGPathRelease(path);
 
    [self.markerImageView.layer addAnimation:pathAnimation forKey:@"moveMarker"];
 
}

6.开始动画,确定百分比

- (void)refreshJumpNOFromNO:(NSString *)startNO toNO:(NSString *)toNO {
 
    beginNO = 0;//[startNO integerValue];
    jumpCurrentNO = 0;//[startNO integerValue];
    endNO = [toNO integerValue];
    _percent = endNO * 100 / MaxNumber;    
    NSInteger diffNum = endNO - beginNO;    
    if (diffNum <= 0) {        
        return;
    }    if (diffNum < 100) {
        _intervalNum = 5;
    } else if (diffNum < 300) {
        _intervalNum = 15;
    } else if (diffNum <= MaxNumber) {
        _intervalNum = 10;
    }    
    NSLog(@"数字间隔：%ld",_intervalNum);    
    //数字
    [self setupJumpThings];    
    // 设置角度
    NSInteger angle = 0;   
    NSInteger num = [toNO floatValue] - [startNO floatValue];    
    if (num < 200) {
        angle = self.startAngle + 220 * (num / 200.0) / 5.0;
    } else if (num < 350) {
        angle = self.startAngle + 220 / 5.0 + (3 / 5.0 * 220) * (num - 200) / 150.0;
    } else {
        angle = self.startAngle + 220 / 5.0 * 4 + (220 / 5.0) * (num - 350) / 250.0;
    }    
    //光标
    [self createAnimationWithStartAngle:degreesToRadians(self.startAngle)
                               endAngle:degreesToRadians(angle)];
}
 
- (void)setBgImage:(UIImage *)bgImage {
 
    _bgImage = bgImage;    self.bgImageView.image = bgImage;
}
 
- (UIImageView *)bgImageView {    if (nil == _bgImageView) {
        _bgImageView = [[UIImageView alloc] init];
    }    return _bgImageView;
}

7.跃动数字

- (void)setupJumpThings {
 
    animationTime = _percent * kTimerInterval;    
    self.fastTimer = [NSTimer timerWithTimeInterval:kTimerInterval*kFastProportion
                                             target:self
                                           selector:@selector(fastTimerAction)
                                           userInfo:nil
                                            repeats:YES];
    [[NSRunLoop currentRunLoop] addTimer:_fastTimer forMode:NSRunLoopCommonModes];    
    //时间间隔 = （总时间 - 快时间间隔*变化次数）/ 再次需要变化的次数
    //快时间
    NSInteger fastEndNO = endNO * kFastProportion;    
    NSInteger fastJump = fastEndNO/_intervalNum;    
    if (fastJump % _intervalNum) {
        fastJump++;
        fastEndNO += _intervalNum;
    }    
    CGFloat fastTTime = fastJump*kTimerInterval*kFastProportion;    
    //剩余应跳动次数
    NSInteger changNO = endNO - fastEndNO;   
     NSInteger endJump = changNO / _intervalNum + changNO % _intervalNum;    
     //慢时间间隔
    NSTimeInterval slowInterval = (animationTime - fastTTime) / endJump;    
    self.slowTimer = [NSTimer timerWithTimeInterval:slowInterval
                                             target:self
                                           selector:@selector(slowTimerAction)
                                           userInfo:nil
                                            repeats:YES];
    [[NSRunLoop currentRunLoop] addTimer:_slowTimer forMode:NSRunLoopCommonModes];
    [_fastTimer setFireDate:[NSDate distantFuture]];
    [_slowTimer setFireDate:[NSDate distantFuture]];
}

8.定时器触发事件

#pragma mark 加速定时器触发事件
- (void)fastTimerAction {    
if (jumpCurrentNO >= endNO) {
        [self.fastTimer invalidate];        
        return;
    }    if (jumpCurrentNO >= endNO * kFastProportion) {
        [self.fastTimer invalidate];
        [self.slowTimer setFireDate:[NSDate distantPast]];        
        return;
    }
    [self commonTimerAction];
}
#pragma mark 减速定时器触发事件
- (void)slowTimerAction {    
    if (jumpCurrentNO >= endNO) {
        [self.slowTimer invalidate];        
        return;
    }
    [self commonTimerAction];
}
 
#pragma mark 计时器共性事件 - lable赋值 背景颜色及提示语变化
- (void)commonTimerAction {    
    if (jumpCurrentNO % 100 == 0 && jumpCurrentNO != 0) {        
    NSInteger colorIndex = jumpCurrentNO / 100;        
    dispatch_async(dispatch_get_main_queue(), ^{            
        if (self.TimerBlock) {                
            self.TimerBlock(colorIndex);
            }
        });
    }    
    NSInteger changeValueBy = endNO - jumpCurrentNO;    
    if (changeValueBy/10 < 1) {
        jumpCurrentNO++;
    } else {
//        NSInteger changeBy = changeValueBy / 10;
        jumpCurrentNO += _intervalNum;
    }
 
    _showLable.text = [NSString stringWithFormat:@"%ld",jumpCurrentNO];    
    if (jumpCurrentNO < 350) {
        _markedLabel.text = @"营养太差";
    } else if (jumpCurrentNO <= 550) {
        _markedLabel.text = @"营养较差";
    } else if (jumpCurrentNO <= 600) {
        _markedLabel.text = @"营养中等";
    } else if (jumpCurrentNO <= 650) {
        _markedLabel.text = @"营养良好";
    } else if (jumpCurrentNO <= 700) {
        _markedLabel.text = @"营养优秀";
    } else if (jumpCurrentNO <= 950) {
        _markedLabel.text = @"营养较好";
    }
}

二. 在所需的当前控制器里展示:

创建背景色

- (void)setupGradientView {    
    self.gradientView = [[ZLGradientView alloc] initWithFrame:self.view.bounds];
    [self.view addSubview:self.gradientView];
}

2. 创建仪表盘

- (void)setupCircleView {    
    self.dashboardView = [[ZLDashboardView alloc] initWithFrame:CGRectMake(40.f, 70.f, SCREEN_WIDTH - 80.f, SCREEN_WIDTH - 80.f)];    
    self.dashboardView.bgImage = [UIImage imageNamed:@"backgroundImage"];
    [self.view addSubview:self.dashboardView];
}

3. 添加触发动画的点击按钮

- (void)addActionButton {    
    UIButton *stareButton = [UIButton buttonWithType:UIButtonTypeCustom];
    stareButton.frame = CGRectMake(10.f, self.dashboardView.bottom + 50.f, SCREEN_WIDTH - 20.f, 38.f);
    [stareButton addTarget:self action:@selector(onStareButtonClick:) forControlEvents:UIControlEventTouchUpInside];
    [stareButton setTitle:@"Start Animation" forState:UIControlStateNormal];
    [stareButton setBackgroundColor:[UIColor lightGrayColor]];
    stareButton.layer.masksToBounds = YES;
    stareButton.layer.cornerRadius = 4.f;
    [self.view addSubview:stareButton];
 
    _clickBtn = stareButton;
}

4. 改变 Value

- (void)addSlideChnageValue {    
    CGFloat width = 280;    
    CGFloat height = 40;    
    CGFloat xPixel = (SCREEN_WIDTH - width) * 0.5;    
    CGFloat yPixel = CGRectGetMaxY(_clickBtn.frame) + 20;   
    CGRect slideFrame = CGRectMake(xPixel, yPixel, width, height);   
    UISlider *slider = [[UISlider alloc] initWithFrame:slideFrame];
 
    slider.minimumValue = MinNumber;
    slider.maximumValue = MaxNumber;
 
    slider.minimumTrackTintColor = [UIColor colorWithRed:0.000 green:1.000 blue:0.502 alpha:1.000];
    slider.maximumTrackTintColor = [UIColor colorWithWhite:0.800 alpha:1.000];    /**
     *  注意这个属性：如果你没有设置滑块的图片，那个这个属性将只会改变已划过一段线条的颜色，不会改变滑块的颜色，如果你设置了滑块的图片，又设置了这个属性，那么滑块的图片将不显示，滑块的颜色会改变（IOS7）
     */
    [slider setThumbImage:[UIImage imageNamed:@""] forState:UIControlStateNormal];
    slider.thumbTintColor = [UIColor cyanColor];
 
 
    [slider setValue:0.5 animated:YES];
 
    [slider addTarget:self action:@selector(slideTap:)forControlEvents:UIControlEventValueChanged];
 
    [self.view addSubview:slider];
 
    _slider = slider;
}

- (void)slideTap:(UISlider *)sender {    
    CGFloat value = sender.value;   
    NSLog(@"%.f",value);
}
 
- (void)setupGradientView {    
    self.gradientView = [[ZLGradientView alloc] initWithFrame:self.view.bounds];
    [self.view addSubview:self.gradientView];
}
- (void)setupCircleView {    
    self.dashboardView = [[ZLDashboardView alloc] initWithFrame:CGRectMake(40.f, 70.f, SCREEN_WIDTH - 80.f, SCREEN_WIDTH - 80.f)];    
    self.dashboardView.bgImage = [UIImage imageNamed:@"backgroundImage"];
    [self.view addSubview:self.dashboardView];
}
 
- (void)onStareButtonClick:(UIButton *)sender {    
        if (sender.selected) {
        [self.gradientView removeFromSuperview];        
        self.gradientView = nil;
        [self.dashboardView removeFromSuperview];        
        self.dashboardView = nil;
 
        [self setupGradientView];
        [self setupCircleView];
 
        [self.view bringSubviewToFront:self.clickBtn];
        [self.view bringSubviewToFront:_slider];
    }
    sender.selected = YES;    
    CGFloat value = _slider.value;   
    NSString *startNO = [NSString stringWithFormat:@"%d", MinNumber];    
    NSString *toNO = [NSString stringWithFormat:@"%.f",value];//@"693"; 950
    NSLog(@"endNO:%@",toNO);
    [self.dashboardView refreshJumpNOFromNO:startNO toNO:toNO];
 
    __block typeof(self)blockSelf = self;    self.dashboardView.TimerBlock = ^(NSInteger index) {
        [blockSelf.gradientView setUpBackGroundColorWithColorArrayIndex:index];
    };
}
