SAPUI5应用从iPhone主屏幕图标启动异常进入独立模式咨询

Yeah, this is a super common quirk with SAPUI5-built apps that I’ve heard from multiple developers. Let me break down what’s going on here based on your observation and some hands-on testing:

• Even if you don’t include the <meta name="apple-mobile-web-app-capable" content="yes"> tag, adding a SAPUI5 web app to your iPhone home screen and launching it from the icon still drops you into full-screen standalone mode—hiding Safari’s address bar and controls, which shouldn’t happen by default without that tag.
• Worse, even explicitly setting <meta name="apple-mobile-web-app-capable" content="no"> doesn’t resolve the issue; the app still forces full-screen mode regardless.

I’ve verified this behavior across multiple cases: SAPUI5’s own official documentation web apps do the exact same thing—launching from the iPhone home screen always triggers full-screen mode. On the flip side, regular non-SAPUI5 web apps behave as expected: without the apple-mobile-web-app-capable tag, they launch in a standard Safari window with the address bar fully visible.

It appears this is a default behavior baked directly into the SAPUI5 framework itself—likely the framework is overriding or automatically handling Apple’s web app mode logic at runtime, bypassing the meta tag settings you specify in your HTML file.
