iOS uses Safari for webview and does not allow any other browsers, so other “browsers” you see on iOS are just Safari wrapped in different skins. That means their usual extensions wouldn’t work.
There’s a system-level content blocker feature that can block ads for Safari in iOS, but I don’t know if there is anything quite comparable to uBlock Origin available.
Not iOS
