when I put the following code in category or homeViewController, the app will crash: [UIFont st_hookClassMethod:@selector(systemFontOfSize:) option:(STOptionInstead) usingIdentifier:(@"myHook_fontWithSize") withBlock:^UIFont (id params, CGFloat oldPara){ UIFont oldRet; [params invokeAndGetOriginalRetValue:&oldRet]; CGFloat newSize = oldRet.pointSize * 2; return [UIFont fontWithName:oldRet.familyName size:newSize]; }];

the crash info is: 2023-06-28 18:00:33.468715+0800 ChangeFontSizeTest[1784:376274] [Assert] UINavigationBar decoded as unlocked for UINavigationController, or navigationBar delegate set up incorrectly.
