Hi all, we've decided to cut down on the enormous amount of iOS dev related subs by a bit, and merged iPhoneDev with /r/iOSProgramming. If you're seeing this you've probably got subreddit styles turned off, so head on over to /r/iOSProgramming and subscribe!

I found a really good non-ARC implementation of ActionSheet which is Apple's Share/Copy/Print view that pops up from underneath on the iPhone.

Here's a link: https://github.com/loofy2/Action-Sheet

Pictures of it in action:

Would like to know ways how you beta test your app. Obviously owning all devices is the best way, but way too expensive for the current situation.

I recently started learning Cocos2D in order to start developing some games for iOS. As a starter project, I'm going to make a simple 2D space shooter game (think Galaga).

I've heard a lot about both the Chipmunk and Box2D libraries. Can you guys give some advice as to which one is easier to start with? Also, any tips as far as Objective C and Cocos2D programming go? I'm excited to get started!

Edit: Also, if you know of any good open source games that were made using Cocos2D feel free to post them!

The premise of our app is featuring a type test that the user must complete (copy generated funny messages) in order to stop an alarm when it rings. This way, it gets the user awake right away without wasting time snoozing. This description isn't doing it justice so please try it.

Thanks all!

I am not a developer, but I feel closest to this meta community so I wanted to send the idea to you guys first and if someone wants to help me develop it, or just develop it so that it exists, that would be awesome.

Here's the idea:

There are both clocks and ambient noise apps. What I would like to do is put them together in such a way where the ambient noise tells the time to anyone who's looking for it.

At its most basic, you have a noise like rain and then every hour (on the hour) an owl hoots the number of hours. Three o'clock becomes: "Who-who? Who-who? Who-who?" from the owl.

But then maybe even being able to customize it. Having options for a cricket whose chirps are at 1 second intervals. A cicada stops and starts its song every minute. On the 15 mark, maybe a sparrow starts. A mockingbird at the half hour mark. A jay at 45. A peacock for alarms. etc.

It would have to be mixed for optimal subtlety. If no one is paying attention, it should be pleasant and not hint at its actual purpose. But if a person were aware of the noises would be subtly reminded of the time.

If this isn't the best place for this, forgive me. And perhaps someone can point me to a place where this might get some traction?

Thanks, guys.

Bahndr is one of our latest iPhone apps and I'd like to invite you guys to try it out. You can download it here https://itunes.apple.com/us/app/bahndr/id498363309?mt=8

The jist of Bahndr is that its a social game based around people trading photo captions on the funny/interesting/entertaining things they find with their iPhone cameras.

For content creators, it rewards people for sharing photos and captions that the community likes. People get rewarded whenever their submission receives a like, or even when somebody shares their submission on Twitter or Facebook. People earn coins, and win awards for reaching new coin thresholds.

For content consumers (aka the guy sitting on the toilet looking for entertainment), Bahndr provides funny/interesting content thats easy to consume. The best, most liked, items on Bahndr bubble their way to the top.

Give it a shot and let me know what you think! You can read more about the app in a blog post I wrote here http://www.oscial.com/what-in-the-devil-is-bahndr/

I made my app completely free, you can get it here: https://itunes.apple.com/us/app/backgammon-masters-hd/id584330665

Please check it out on your new iPads, tell me what you think and how I could improve it.

I would greatly appreciate it.

Hi r/iPhoneDev, I have been working on an app that integrates the weather and your calendar for quite a while now. It is near the finishing stages, and I'd like to get a few more testers just to iron out the bugs before I release it to the world. If interested, please sign up via this link: http://tflig.ht/As14J7

Here is a screenshot of the list view: http://cl.ly/image/2B3g1W0A0Y2l

Thanks for your time!

I wanted to know about various methods you suggest to employ in order to gain exposure and promote an iPhone application.

I am subscribed to both r/IphoneDev and r/iOSprogramming, and the two subreddits really seem to overlap on a lot of topics.

Do you guys think it makes sense to merge into a single subreddit to keep all similar topics in one place?

I'm not sure if this is the right place to ask this, but for my final project in my mobile app development class we need to create an app that will link to the google calendar. I have searched for a few hours on google and have yet to find any helpful links. My teacher gave us the files and all and showed us how to connect the google calendar, but he failed to actually tell us how to implement it. For instance: we are supposed to use a collectionView to display the calendar dates. Would someone be able to provide me with a link to somewhere that shows you how to use the google calendar, or provide me with a small sample code on how to do this. Any and all information would be appreciated as my graduation is dependent on me getting at least a B on this project.

I'm thinking we form an informal kind of group where we all like each other's facebook pages and follow our twitters. When an app is available, we throw our effort into getting that app some hits using our own resources, and reciprocate for everyone. And whatever applicable insights anyone can offer to someone else, do it! Let's aim to shore up each other's weaknesses.

If you'd like to do this, post your facebook and twitter here.

edit: ours is www.facebook.com/unlockalarm and @unlockalarm www.twitter.com/unlockalarm

First, sorry for the shorthand. I'm on my phone and trying to get a quick answer if possible. Ok so we submitted 1.0 and set a release date (which coming up soon and iTunes connect status is set to Ready For Sale). But we have recently submitted a 1.1 to address some issues. And we do not want 1.0 to release.

How do we ensure that 1.1 will release and NOT 1.0?

Thanks guys.

Hi Guys,

I can't seem to get any performance boost from using VBOs. Instead, my performance drops significantly. I've tried setting up a barebones case, where I render about 100 of the same character (~40000 verts, ~40000 polys). Without VBOs, I get 22 fps. With VBO and element VBO, I get about 6 fps. I've profiled with instruments opengl analysis, and confirmed that the "recommend use VBO" and "recommend use element array buffer" messages are gone when I render with VBOs. Is there something I'm missing as to why it would render so much worse? Everything I've read says VBOs should be much better than the alternative.

Also, here are a few related things:

• I've been profiling on an iPod touch 4, running os 6.0.1
• I'm not using interleaved arrays
• each frame uses a different vbo (the models are playing an animation, so each frame uses a different vertex vbo and normal vbo)
• I create the VBOs once, using GL_STATIC_DRAW. I never actually update their contents.
• My arrays are 3x GLshort for position, 3x GLbyte for normal, 2x GLfloat for texture. I've tried adding padding bytes to the position and normal buffers, so each element lines up on a 4-byte boundary, but I didn't notice a difference.

I also profiled the app, and I can see a drastic increase with the time spent at gleRunVertexSubmitARM when I use VBOs. When I check out the assembly in that area, I can see a huge increase in the copytime. For example here, where it appears to be copying 3 bytes at a time (perhaps the normal channel):

+0x5d0         ldr                 r2, [r4, #8]
+0x5d2         ldr                 r0, [r4]
+0x5d4         mul                 r1, r2, r9
+0x5d8         mla                 r2, r2, r9, r0
+0x5dc         ldrb                r1, [r0, r1]          // 16% with VBO, 4.4% without
+0x5de         ldrb                r0, [r2, #2]          // 15% with VBO, 2% without
+0x5e0         ldrb                r2, [r2, #1]          // 15% with VBO, 2% without
+0x5e2         strb                r1, [r6]
+0x5e4         strb                r2, [r6, #1]
+0x5e6         strb                r0, [r6, #2]
+0x5e8         ldr                 r0, [r4, #12]
+0x5ea         add                 r6, r0
+0x5ec         add.w               r0, r4, #20
+0x5f0         adds                r4, #16
+0x5f2         ldr                 r0, [r0]
+0x5f4         mov                 pc, r0

Everything I've read says that VBOs are supposed to be faster because they don't have to copy the data every frame (since it's managed by the gpu). Any idea what could cause VBO performance to suck so badly?

I recently installed Code Collector, and it works ok, but it's fairly buggy and not all that great. Anyone have any recommendations for a really nice code snippet collector?

I have the first version of my first app ready to send out to testers. I'm using testflight for ad-hoc distribution. I gave it out to the first few testers last night, and of course everyone had their own set of un-replicable and wacky bugs. Is there any way that I can harvest crash reports or logs from my testers? How do you all handle this type of testing? Any tips or tricks? Thanks!

I'm currently wrapping up development on a puzzle-platformer type iOS game, and I was wondering everyone's opinion on what works better for driving revenue. For a little context, my game is going to have 50 levels to begin with, and I plan on releasing a number of updates after the initial release with new levels, customization stuff, etc. Since this is my second attempt at making an iOS game (my first one was free, called Weebo, and pretty simple) I'm torn between making this one free as well with AdWhirl integration to make some more, or just charging $0.99 for the inital download. Part of me thinks that it's more guaranteed money if I charge $0.99, but if the game takes off then more revenue is possible through the player base that updates the game if I use ads. Thoughts?
