i have any problems with ngx.translate on IOS.
On android device all function perfectly but on IOS ngx-traslate not work.
In the main view i can choose the language, if i choose "fr" i set "fr" in db and then i take the value from db and use : this.translate.use(lng);
In db i change correctly the value, indeed the json that i download (in other views) is with the right language, but the variable on html code {{ 'MONTH.JENUARY' | translate }} it don't take the value.
Why on ios not work?
I tried to update ngx-translate, i tried to use ionViewWillEnter, but I don't understand because it works on android and not on ios
can someone help me?
I using custom font for my Flutter app:
return MaterialApp (
theme: ThemeData(
fontFamily: "MyFont"
)
)
but in one place of application I need to use "system font". this is especially important for iOS (Sf Pro). If I understand correctly, this is the system font for iOS. But how can I use "system font" if I already use "custom font" at application level?
I tried:
final fontFamily = DefaultTextStyle.of(context).style!.fontFamily;
But this code return "MyFont".
also I tried importing from apple site. but there is only one big SF-Pro.ttf(8Mb) file inside the image. Not - SFPro-Regular.ttf, SFPro-SemiBold.ttf ... Flutter does not support .otf files.
How to solve this problem? any advice I will be grateful

Much like you I experienced this Unrecognized Font family issue when running the iOS build via Terminal. For whatever reason, it doesn't effect the final archive build or if one runs the build via Xcode. This is on the latest RN 0.63.3 in macOS Catalina 10.15.7 with Xcode 12.0.1.
The issue was with the font name itself.
Solution Summary
In your case, I recommend the following steps to take.
Install your font sfprogregular on your macOS system
With the font installed, and selected in Font Book press CMD+I to see postscript name
Rename the font files in your project to their respective PostScript names
Run npx react-native link in your project to setup the renamed fonts
Do cleanup of the older font files prior to the rename (remove old fonts)
Change the name of the font to the postscript name in code when referring to the font in styles
My experience detailed
In my case, we are using TradeGothic.
Initially, when we linked the font, the name of the font file itself was:
Trade Gothic LT.ttf
Android is fine with this, but not iOS. That's because Android relies on the filename, but iOS depends on the PostScript name of the font.
To fix this, I renamed the ttf file to it's postscript name TradeGothicLT.ttf. For the bold one which was Trade Gothic LT Bold.ttf I renamed it to TradeGothicLT-Bold.ttf.
I then did npx react-native link inside my project to connect my newly renamed fonts. Then, I cleaned up by removing the older .ttf files from the XCode project under resources (just press delete on each of the red font files that are no longer there) and removed the font files from the older Android link process in the folder /android/app/src/main/assets/fonts/. In the info.plist file, under the section UIAppFonts remove the older font filenames.
Finally in code, instead of referring to 'Trade Gothic LT' we now refer to it as 'TradeGothicLT'. That's it, it works now!
You can find the postscript name of the font by installing the .ttf file (double click it) on macOS and in Font Book with the font selected press CMD+I to get information about the font.
NOTE: It's not necessary to install the font to macOS, it's just the only way I know of to get the PostScript name. If you already have the PostScript name of the fonts, you don't need to install them.
I hope this helps you and others that might stumble upon this issue!
After adding the custom fonts, you need to link it using react-native link.
That will create an entry in Info.plist file (iOS) & android/src/main/assets/fonts/ directory (Android).
If the above command fails, you need to add those fonts manually in the android directory & plist file.
Sometimes your font name is not the same for Android and iOS (since iOS uses postscript name as fontFamily). In most cases, in android, the font is the same as the file, for example, I had this problem when using HelveticaNeueLTPro-BdEx font in iOS.
I am sharing the fix that helps me out.
Run npx react-native link. Maybe you already did.
Add this inside the didFinishLaunchingWithOptions method on your AppDelegate.m:
for (NSString *familyName in [UIFont familyNames]){
NSLog(#"Family name: %#", familyName);
for (NSString *fontName in [UIFont fontNamesForFamilyName:familyName]) {
NSLog(#"--Font name: %#", fontName);
}
}
Then, when you launch your app with xcode, you will be able to see all the fonts installed on your app, so you just have to use it the way it is listed on your console:
You can add fontFamily based on OS like:
Platform.OS == 'android' ? 'Linotype - HelveticaNeueLTPro-BlkEx' : 'HelveticaNeueLTPro-BlkEx'
Or you can rename the font file name and then run npx react-native link again and also maybe have to delete the previous UIAppFonts entry for the previously linked font in Info.plist file.
I am trying to reuse some components built for web application using reactjswith radium.
I have a component which contains outline css property . I reuse the component , unfortunalty , i got this error :
My questions are :
What is the alternative of outline property in react-native for both ios or android ?
Is there alternative of radium in react-native ?
Should I manage manually this difference of style properties naming among iOs DEV, android DEV as well as web DEV ?
I think you are looking for the border styles.
More specifically from the facebook react native docs:
borderWidth ReactPropTypes.number
borderStyle ReactPropTypes.oneOf(['solid', 'dotted', 'dashed'])
So for instance if you wanted to make a 10 x 10 box with dashed lines...
<View style={{ borderWidth:1, borderStyle: 'dashed', width: 10, height: 10, }} />
I'm currently loading two fonts from a qrc file. One of them is .ttf and the other is .otf. When I test my build on Android, they load and work fine (although the loading time is fairly long..)
However when I test it on my iPhone and/or simulator, none of the fonts load at all. They just seem to default back to Arial or something. Furthermore, only the .otf file works fine on Windows. The .ttf file defaults back to Arial and the characters are offset by 2 characters (so the word "ok" would be "qm")
What the hell is going on?
The fonts are located in:
"qrc:/fnt/res/fnt/MuseoSans_500.otf"
"qrc:/fnt/res/fnt/museo100-regular.ttf"
and I'm using this to load the fonts:
FontLoader {
id: museosans500
source: "qrc:/fnt/res/fnt/MuseoSans_500.otf"
}
FontLoader {
id: museo100
source: "qrc:/fnt/res/fnt/museo100-regular.ttf"
}
When accessing the fonts I set the font.family to museosans500.name and museo100.name. Like I said, they work fine on Android. But neither work on iOS, and only one of them works on Windows.
I'm using Qt Creator 3.4.0 and Qt 5.4.1.
Any help is much appreciated!
So I didn't solve it for Windows but this is an application for iOS and Android.
Basically I loaded the fonts through main.cpp instead with:
int main(int argc, char *argv[])
{
QGuiApplication app(argc, argv);
// Load custom fonts
if(QFontDatabase::addApplicationFont(QStringLiteral(":/fnt/res/fnt/MuseoSans_500.otf")) == -1)
qDebug() << "Failed to load font Museo Sans 500";
if(QFontDatabase::addApplicationFont(QStringLiteral(":/fnt/res/fnt/museo100-regular.ttf")) == -1)
qDebug() << "Failed to load font Museo 100";
QQmlApplicationEngine engine;
engine.load(QUrl(QStringLiteral("qrc:/res/qml/LoadScreen.qml")));
return app.exec();
}
Originally this didn't actually work. But that's because I was setting the font.family to be "Museo Sans 500" and "Museo 100" since that is what Windows would print in console when I asked for a full list of available font families.
When I printed out the font families list in Android, Mac and iOS I actually got "Museo Sans" and "Museo" respectively. Changing the font.family to those strings worked fine.
Unfortunately I have found no solution for Windows yet, but like I've said that doesn't matter to me.
