I'm learning Swift, my project is make a simple music player, I'm trying to toggle between UIBarButtonSystemItem.Play and UIBarButtonSystemItem.Pause, but all what I got across 30 minutes of searching is this toggle between UIBarButtonSystemItemPlay and UIBarButtonSystemItemPause, but it's written on Objective-C, I don't know anything about Objective-C.
What's the correct way to get this?

I just started learning swift and decided to build a simple BMI calculator just to kind of learn everything. I think I've got everything working, but I can't hit the calculate button to test it because I can't get the keyboard to dismiss.
I've been looking all over the place trying to find a straight forward answer to this but can't seem to find one.
Any help is greatly appreciated. I can add my code if need be.
Also, im using Xcode 11 and SwiftUI
I want to know how to create a custom tvOS screensaver. Ideally in Swift. If there is no such thing yet (macOS has ScreenSaverView for example) please tell me if there is another way to create a custom screensaver
No that is unfortunately not possible to do today with tvOS. You have to use the built-in ones.
I have written code so that technically there should be two MPMoviePlayerControllers within the same view, both ready to play an audio file. What always happens is that one pops up and disappears, and the other comes up and stays, and is fully useable.
Any idea why one disappears? I'm not trying to play two at once, just want to give users the option to play from different sources.
There can only be one active MPMoviePlayerController, it won't mind if the user didn't play it yet. I do not know the technical reason, but I do know that this is the normal behavior when you do that.
My advice would be to use AVAudioPlayer to achieve what you want. The sad part if that you will have to implement the UI of the player.
I'm wanting to put together an application which plays video fullscreen with an interface overlaying it that basically chooses the video that is played underneath it (think 'Gym Babes' but nowhere near as risqé!). I don't wish to use private headers so MPMoviePlayerController is out of the question.
I've been digging through stackoverflow for a while and have come to the conclusion that I would need to use some sort of custom codec/video library that I assume would be written in C.
My question is basically has anyone had success doing this? And can anyone share any code, tutorials etc they can share?
You probably want to take a look at AVPlayerLayer: http://developer.apple.com/library/ios/documentation/AVFoundation/Reference/AVPlayerLayer_Class/Reference/Reference.html it gives you basic playback abilities with no (read fully customizable) interface…

How can i use picker view in iphone application using cocos2d ?
Hello everyone i am working on iphone gaming project.In this game i want spin some image (like reel spin).But i can not do this.Can i use picker view in this application using cocos2d.If can then give some instruction how can i do that or any different solution for this project.
You can use anything your want. I am constantly amused by the number of people who think that Cocos2d is some sort of world that you enter where you cannot bring any of your old friends. Cocos2d is just a library that makes OpenGL easy for games, and that is all it is. All it is.
I think you might benefit from trying a few easier projects first. I have made the mistake of trying to jump into something beyond my understanding, and while in the end it may have been beneficial, I sometimes wish I had learned in a more systematic manner.
