Today Apple released Keynote 7.1. One of the new features is easy to replace a font in your presentation.
If you open your presentation in Keynote 7.1, there is a new font management window.
My first impression is much better intuitive to manage my font. I encourage you to use Keynote 7.1. You can update your Keynote through MacAppstore now.

Recently I tried to use this method for my development in iOS10. By the way the function isn’t work in iOS10. It always returns false value.
I hope that Apple fixs it as soon as possible.

InfoPlist.strings file and localize it.
After that remember you need to key value to translate a text in infoplist file. "NSLocationWhenInUseUsageDescription" = "BlahBlahBlah"
If you manually create a parent and child relationship between two view controllers, the child view controller might not have a navigation bar in this case. So you might be wondered why the navigation item of the child view controller doesn’t effect on the navigation bar. But you need to understand that the navigation bar on the child view controller is not the child view controller’s navigation bar. Because the child view controller is embedded into the parent view controller. So you need to create a LeftBarButtonItem on the parent’s navigation bar and customize the button with a target and an action pattern in the parent view controller.

dispatch, dispatch_group, GCD, loop, Swift, thread

A completion Handler in iOS takes a thread to asynchronously get it done. So it means that we can’t know an exact point which the tasks finish. For example, if we use a for loop to execute several tasks in the background, how could we know all the task are done?
In this case you can use dispatch_group.
dispatch_group_create().dispatch_group_enter(groupname).dispatch_group_leave(groupname).dispatch_group_notify.If you want to see a concrete example for it, please refer this.
