[翻译] TSActivityIndicatorView 自定义指示器

本文介绍了一个自定义指示器类TSActivityIndicatorView,它提供了一种简单且高度可定制的方法来实现UIActivityIndicatorView的自定义。通过引入类并利用keyPath传递图片名称,开发者可以轻松地创建出具有不同外观和动画效果的指示器。

TSActivityIndicatorView

This is very simple view class that looks like an UIActivityIndicatorView but is fully customizable. It's great for you if you want to add indicator view to you game or app and it should be customized. If you use this class you can not only make circular Indicators, you can add images that are wide and have e.g. 3 rotating balls etc. (instead of one object which rotate in native UIActivityIndicator).

这是一个非常简单的view类,看起来像UIActivityIndicatorView并能完全的定制.如果你想定制UIActivityIndicatorView,那它非常有用.你还可以用图片来定制它哦.

 

Why should i use it?

As I mentioned earlier, if you want to have nice looking indicator view, use this class.

正如我说的那样,你想你的UIActivityIndicatorView好看点,就用这个类.

 

Is it better than animated UIImageView?

Yes. You can use it in very simple way in Interface Builder. You only have to pass images names in keyPath and that's all. Look below.

对的,你可以在IB中使用它.你只需要在keyPath中传递图片的名字,that's all.

 

How can i use it? Is it difficult?

There are two ways to use it and both are simple. Sounds good, ha?

有两种方式可以是哦那个,很简单滴.

 

Fully programically

First things first. You have to import class.

首先,你得先引入类.

#import "TSActivityIndicatorView.h"

Next thing to do is create instance.

然后,创建出实例对象.

    TSActivityIndicatorView *customIndicator = 
    [[TSActivityIndicatorView alloc] initWithFrame:CGRectMake(160-17, 100, 35, 35)];

Then you have to import images to your project and add titles to the frames property as an NSArray object.

之后,你需要将图片名赋值给NSArray即可.

    customIndicator.frames = @[@"activity-indicator-1",
                               @"activity-indicator-2",
                               @"activity-indicator-3",
                               @"activity-indicator-4",
                               @"activity-indicator-5",
                               @"activity-indicator-6"];

Next you may set duration time of whole animation.

然后,你设置下完整动画的时间.

    customIndicator.duration = 0.5f; /// Default is 1.0f

Penultimate step is to run this indicator.

倒数第二步是让他跑起来.

    [customIndicator startAnimating];

And after your things are done, stop indicator it by calling stopAnimating

等你的活干完了,让它停下来.

    [customIndicator stopAnimating];

Both startAnimating and stopAnimating methods are executed in Main Thread.

注意:startAnimating以及stopAnimating都是在主线程中运行的哦.

 

 

 

 

 

 

内容概要:本文系统介绍了算术优化算法(AOA)的基本原理、核心思想及Python实现方法,并通过图像分割的实际案例展示了其应用价值。AOA是一种基于种群的元启发式算法,其核心思想来源于四则运算,利用乘除运算进行全局勘探,加减运算进行局部开发,通过数学优化器加速函数(MOA)和数学优化概率(MOP)动态控制搜索过程,在全局探索与局部开发之间实现平衡。文章详细解析了算法的初始化、勘探与开发阶段的更新策略,并提供了完整的Python代码实现,结合Rastrigin函数进行测试验证。进一步地,以Flask框架搭建前后端分离系统,将AOA应用于图像分割任务,展示了其在实际工程中的可行性与高效性。最后,通过收敛速度、寻优精度等指标评估算法性能,并提出自适应参数调整、模型优化和并行计算等改进策略。; 适合人群:具备一定Python编程基础和优化算法基础知识的高校学生、科研人员及工程技术人员,尤其适合从事人工智能、图像处理、智能优化等领域的从业者;; 使用场景及目标:①理解元启发式算法的设计思想与实现机制;②掌握AOA在函数优化、图像分割等实际问题中的建模与求解方法;③学习如何将优化算法集成到Web系统中实现工程化应用;④为算法性能评估与改进提供实践参考; 阅读建议:建议读者结合代码逐行调试,深入理解算法流程中MOA与MOP的作用机制,尝试在不同测试函数上运行算法以观察性能差异,并可进一步扩展图像分割模块,引入更复杂的预处理或后处理技术以提升分割效果。
