rmq.append(UIImageView).on(:force_touch)

Apple Watch, iPhone 6 , 6+, and iOS8: there are many new and exciting things in the iOS world right now. I’m personally excited about WatchKit, as the Apple Watch is a whole new device for us to build apps on, with fun new UI constraints and metaphors.

The different point sizes of the iPhone 5, 6, and 6+ are going to add some additional work for us. If you’re using MotionKit’s Auto Layout or RMQ’s grid system you’ll be better off than most.


If you missed the last issue, you can find it here: issue #42.

Happy coding, Todd Werth (@twerth)

RMQ Tip of the Week


Version 0.7.1 was released yesterday. It adds a grid overlay and some very cool new validation features.

Gant Laborde and Vaughan added some cool new validation features:

white_list

In some situations you may have an outlying exception to the validation rule. Exceptions can be validated as true using the white_list parameter:

rmq.validation.valid?(some_url_input, :url, white_list: ['http://localhost:8080', 'http://localhost:3000'])
# => true for 'http://localhost:3000' even though it's not going to pass URL (missing TLD)

Custom rules

If your validation is specific to a single form, we suggest taking advantage of using the custom validation rule.

some_field = rmq.append(UITextField).validates(:custom, regex: /^test$/)
some_field.data("test")
some_field.valid?
# => true
add_validator

You can add your own validation with the add_validator method (Perhaps in your Application Stylesheet setup). Additionally, you’re not limited to the bounds of a single regex. You can use the ruby methods you know and understand, as well as multiple parameters passed in opts.

rmq.validation.add_validator(:start_with) do |value, opts|
  value.start_with?(opts[:prefix])
end

You can then use your new validator in your application:

some_field = rmq.append(UITextField).validates(:start_with, prefix: 'x')
some_field.data("test")
some_field.valid? # => false
some_field.data("xenophobia")
some_field.valid? # => true

Grid overlay

I added the ability to see the grid for development:

rmq.app.grid.show

or

rmq.stylesheet.grid.show

or

some_grid.show
