13 | #**Property：** 14 | - cycle —— 循环次数，在控件宽度范围内，该正弦函数图形循环的次数，数值越大控件范围内看见的正弦函数图形周期数越多，波长约短波浪也越陡。 15 | - term —— 正弦周期，在layoutSubviews中根据cycle重新计算，==修改无效== 16 | - phasePosition —— 正弦函数相位，==不可修改==，否则图形错乱 17 | - amplitude —— 波幅，数值越大，波浪幅度越大，波浪越陡，反之越平缓，可通过代码调用`waveAmplitude`修改 18 | - position —— 正弦曲线的X轴 相对于 控件Y坐标的位置，在-drawRect中通过progress计算，==修改无效== 19 | - waveMoveSpan —— 波浪移动的单位跨度，数值越大波浪移动越快，数值过大会出现不连续动画现象 20 | - animationUnitTime —— 重画单位时间，数值越小，重画速度越快频率越大 21 | - heavyColor —— demo中较深的绿色部分 22 | - lightColor —— demo中较浅的绿色部分 23 | - clipCircleColor —— 玻璃球边界颜色 24 | - clipCircleLineWidth —— 玻璃球边线宽度，可通过代码调用`borderWidth`修改 25 | - progressTextFontSize —— 中央进度提示百分比字号大小 26 | 27 | 28 |
29 | #**Usage：** 30 | 1. include the file WaveLoadingView.swift to your project, and about objectiveC, you can create a bridge Header and import it 31 | 2. creat a waveLoadingIndicator instance 32 | ```swift 33 | let waveLoadingIndicator: WaveLoadingIndicator = WaveLoadingIndicator(frame: CGRectZero) 34 | ``` 35 | 3. add waveLoadingIndicator to your imageView, equal bounds here i do , and FlexibleWidth,height 36 | ```swift 37 | self.displayImageView.addSubview(self.waveLoadingIndicator) 38 | self.waveLoadingIndicator.frame = self.displayImageView.bounds 39 | self.waveLoadingIndicator.autoresizingMask = [.FlexibleWidth, .FlexibleHeight] 40 | ``` 41 | 4. and your can used combine with SDWebImage: 42 | ```swift 43 | self.displayImageView.sd_setImageWithURL(url, placeholderImage: nil, options: .CacheMemoryOnly, progress: { 44 | [weak self](receivedSize, expectedSize) -> Void in 45 | 46 | guard let weakSelf = self else { 47 | return 48 | } 49 | 50 | weakSelf.waveLoadingIndicator.progress = Double(CGFloat(receivedSize)/CGFloat(expectedSize)) 51 | }) { 52 | [weak self](image, error, _, _) -> Void in 53 | // 不要忘记在完成下载回调中，移除waveLoadingIndicator 54 | guard let weakSelf = self else { 55 | return 56 | } 57 | 58 | weakSelf.waveLoadingIndicator.removeFromSuperview() 59 | } 60 | ``` 61 | >
62 | > Don't worry， after -removeFromSuperview(), the animation have been stop 63 | 64 | ##Relation 65 | [@liuzhiyi1992](https://github.com/liuzhiyi1992) on Github 66 | [WaveLoadingIndicator](http://zyden.vicp.cc/waveloadingindicator/) in my Blog 67 | 68 | 69 |
