How to localize layout file

In layout file, only view attribute support multi-language. For the attribute value, you can use @ to reference the string in Localizable.strings. Like

    <UILabel attr="text:@title"/>

Notice: if the first character is @, you should use @@ instead of @. Like

    <UILabel attr="text:@@title"/>

The label text will be @title, not the string in Localizable.strings.

By default, the framework will fetch the localizable string from mainBundle. You can implement bundleForStrings in owner to change it.

Should I write a custom base class from FlexBaseVC for my project?

Yes, I recommend it. Although FlexBaseVC works well in most case, you may need some custom behaviour like different safe area for iPhoneX, custom keyboard toolbar etc.

Can I use my custom view class in xml layout file?

Of course you can. But your custom view class must conform with the following rules:

• All the initialization must be done in init method. Any other init function like initWith... will not be called.
• You can extend view attributes with FLEXSET macro, then you can set the attribute in xml file. Then you can use your custom view.

How to scale font size for different screen?

• Call FlexSetScale(factor,offset) to set factor and offset
• In layout file, change number value with * prefix. like:

  <UILabel attr="fontSize: *16"/>

The final font size will be 16*factor+offset

• If your string should start with *， you should use ** instead of *. Thanks for 青柠.

The source attribute of UIImageView support network image?

No. Support network image will need network framework. It will make this framework overstaffed. You can use FLEXSET macro to extend the attribute of UIImageView if you really need it.
