Added support for tvOS

[voidrender]

Added tvOS to the podspec, plus an example project with similar scenarios as the iOS example. Things seem to be working well, but there are two exceptions:

1. FLAnimatedImage does not yet support tvOS. I opened a pull request to add it, but in the meantime, you can run the tvOS example by adding pod "FLAnimatedImage", :git => "https://github.com/ioveracker/FLAnimatedImage", :branch => "tvos" to the Podfile in Example-tvOS, above the line for PINRemoteImage.
2. WebP doesn't seem to work--could be a limitation of the platform, or libwebp may need to be updated.

@ioveracker awesome! I'll try and take a look at this as soon as I can!

[garrettmoon]

FYI, I'm releasing 2.0 very soon, but will make sure to release a 2.1 when we get this in :)

[garrettmoon]

@ioveracker I'm sorry this hasn't made it in yet, embarrassingly, I need to get our team on a newer version of cocoa pods which supports tvOS before I can merge. I'm going to work on that soon! 2.1 will be the tvOS release :)

[voidrender]

No worries! The FLAnimatedImage pull request is still pending as well.

[garrettmoon]

@ioveracker Just finished upgrading the team to CocoaPods so I'm swinging back around to this. I downloaded your branch to give it a try, but I'm not able to get the example to run in Example-tvOS. I get an import error on PINRemoteImage every time.

I'm excited to have a Swift example and tvOS support landed :) Do you have any ideas what could be happening? I pod updated in the directory and that didn't work.

[voidrender]

Hm, I just did a clean clone, updated the Podfile to use my FLAnimatedImage repo (since that pull request is still pending over at FLAnimatedImage), ran pod install, then opened the workspace and it built and started running on the tvOS simulator. I'm running Xcode 7.2.1 now, and was on whatever the latest was when I started this. :)

Since it's using the local files for PINRemoteImage, maybe there's some crossover between work you've been doing on the master branch? I don't know if that's possible, because it should be building it from source, and when switched to the tvos branch, none of the changes from the master branch should be in the source.

[voidrender]

Crossover with the master branch is unlikely--I just pulled the latest master changes into my repo and even merged it into my local tvos branch and didn't encounter any issues. 😕

[garrettmoon]

Ok, I'll give it another try with a clean clone!

[voidrender]

Coming back to this after a month, there are a couple things that I think could be changed (besides the fact that you can't get it to run! 😅) :

1. The WebP example being the first tab isn't exactly ideal, since that's the only example that doesn't actually work on tvOS. 😆 Perhaps it would be better to move this example to the last tab.
2. Since the FLAnimatedImage pull request is still pending, would you like to configure a way to build for tvOS without FLAnimatedImage so non-GIF support can be released separately, while FLAnimatedImage figures out their side of things? Or just wait for that to be merged before this gets merged?
3. I noticed that the Pods directory was committed for the other examples. Would you like the Pods directory to be committed here, too? Will require deciding how to proceed with the FLAnimatedImage side of things first. 😁

[garrettmoon]

@ioveracker Cool! Maybe it will just work with the updates :P

1. Yeah, that sounds good.
2. I think we should configure support for without. Instead of including the PINRemoteImage pod spec, use PINRemoteImage/iOS? Make one for tvOS specifically?
3. Yes, please commit the Pods directory, it makes it more reliable for using pod try

Thanks for you work on this!

[voidrender]

Sounds good! I'll take a stab at these later this evening.

[voidrender]

Okay, I've taken care of the above three items, and rebased the latest changes from master.

1. I removed the GIF and WebP examples. It'll be easy to add them again if/when supported.
2. I added a tvOS subspec. It's identical to the iOS one, but I thought it would be nice to start with a separate subspec in case they diverge.
3. Pods directory committed.

I haven't been able to figure out why the Travis build is failing. Is it really being terminated because the log file is exceeding 4 MB just during the normal build, or is something else going on? I see a similar result in #308.1.

[garrettmoon]

@ioveracker ugh, yeah, travis has been a pain to get working correctly lately. Mind removing the verbose flag in the pod lint step in the .travis.yml file?

[garrettmoon]

Actually, I just removed it, so if you could just rebase, I'd appreciate it.

[voidrender]

No problem! Done.

[garrettmoon]

It works!

[voidrender]

🎉

[garrettmoon]

Thanks again, this is awesome!

[voidrender]

Sure thing! Thanks for all your hard work on PINRemoteImage, it's really great.
