在iPhone应用程序中实现应用程序细化 [英] Implement app thinning in iphone application

问题描述

我的iOS应用程序在应用商店中的尺寸很大.如何降低应用程序精简，以使应用程序尺寸变小.

My iOS application's size is quite bigger on app store. How can I lower achieve the app thinning so that application size get lower.

Note:-

1. 我已经在使用Images.xcassets分别放置x/2x/3x图像.
2. 我还阅读了苹果文档，并仔细阅读了优化级别的构建设置.
3. 我还使用了8位PNG而不是32位PNG.

1. I am already using Images.xcassets to put x/2x/3x images separately.
2. I also read this apple documentation and take care of optimisation level build settings.
3. I am also using an 8-bit PNG instead of a 32-bit PNG.

推荐答案

从昨天开始搜索应用程序细化，位代码和按需应用程序资源，现在我调试所有这些内容并分享我从美丽的苹果文档，并在我的示例项目的帮助下.

Searching app thining, bit code and on demand app resource from yesterday, Now I debug all these things and sharing my knowledge that I got from beautiful apple documentation with help of my sample project.

应用程序稀疏概念涵盖了位代码和按需资源.我将在下面详细讨论按需资源:-

App thinning concept covers bit code and on-demand resource. I will discuss on-demand resource in detail below:-

iOS中的按需资源:- 它会在需要时访问Yes, on-demand resouring include source code files also).

On-Demand Resources in iOS:- It is accessing the images/videos/.h/.m/swift file whenever needed (Yes, on-demand resouring include source code files also).

• 转到目标中的Resource tags设置.
• 创建一个新的Tag.它将显示在仅按需下载"下.
• 您可以在各种标签下添加.h，.m，.xassest，.png等.您还可以通过选择单个文件在文件检查器中像这样.

• Goto Resource tags setting in your target.
• Create a new Tag. It will appear under Download Only On demand.
• You can add .h, .m, .xassest, .png etc under various tags. You can also assign tag by selecting individual file like this in file inspector.

现在是编码部分(我最喜欢的网站):-

Now comes the coding part (my favourite site):-

NSBundleResourceRequest *resourceRequest;


#pragma mark - On demand resource
-(void)getOnDemandResource{
    NSSet *setOfTag = [NSSet setWithObjects:@"chair", nil];
    resourceRequest = [[NSBundleResourceRequest alloc]initWithTags:setOfTag];

    [resourceRequest conditionallyBeginAccessingResourcesWithCompletionHandler:^(BOOL resourcesAvailable) {
        if (!resourcesAvailable) {
//            resourceRequest.loadingPriority = 1;//set the downloading priority (0 - 1) , NSBundleResourceRequestLoadingPriorityUrgent

            [resourceRequest beginAccessingResourcesWithCompletionHandler:^(NSError * _Nullable error) {
                if (error) {
                    UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Error" message:error.debugDescription preferredStyle:UIAlertControllerStyleAlert];
                    [self presentViewController:alert animated:YES completion:nil];
                }else{
                    //// The associated resources are loaded
                }
            }];
        }else{
            // The associated resources are available
        }
    }];
}

在不使用时(通常在游戏级别更改时)结束按需资源的访问

End accessing the on demand resource when not in use(generally when game level changes)

#pragma mark - Remove access to on demand
-(void)endAccessToOnDemandResource{
    [resourceRequest endAccessingResources];
}

NOTE:-不要忘记请不要为这个项目中的自动布局而烦恼.我主要关注需求资源/应用程序事情.

Please don't bother about autolayout in this project. My main focus is on demand resourcing/App thing.

摘要:-因此，使用上述技术，我们可以通过on-demand resourcing来实现app thinning.另请参阅

SUMMARY:- Thus we can achieve app thinning by on-demand resourcing using above technique. Please also have a look at official documentation which also describes about tracking progress, priorities of resourceRequests(NSBundleResourceRequest).
