If you do use it, please give me your honest feedback directly, or via the forums.
How much functionality can you add to a single button?
A lot, if you’re apple.
The iPhone ships with a mic on the earphone cord which is clickable and can do all of the following (in addition to being a microphone):
- Answer Call
- Hang up Call
- Play Music
- Pause Music
- Skip Track (double click)
- Skip Track Backwards (triple click)
6 actions from a single button. I’ve seen other smart phones (e.g. the dopod) actually have 6 separate buttons for these actions What a waste. Amazing. And I only discovered the 6th one today… I wonder if any more surprises await. Can it cook my breakfast?
China Mobile Recharge in English
This guy has some useful tips on recharging – he’s right the english menu is not very clear at all. I have had similar experiances with the kind shop ladies recharging for me – lol, it’s nice to be self sufficient. Stay tuned for some more China Mobile tips.
- dial 13800138000
- 2 [for english]
- 2 [to recharge]
- 1# [to recharge current mobile]
- 1 [to confirm]
- enter PIN
- # [to end]
- All done…
‘Jeff’ has some useful tips (note: these only work if your account actually has credit)
There is a much easier way by utilizing SMS(text message). After obtaining the recharge PIN number, simply send a text message “CZ PIN number” to 10086. If done correctly, you will receive several replies from China mobile in Chinese. CZ is short for “Chu Zhi”, which means “recharge” in Chinese. You can also send “YE” to 10086 to check for your remaining balance. As “Yu Er” is “leftover balance” in Chinese. Hope this helps.
PS. a travel related post! and you thought this was an iPhone blog :P

Re-ordering icons on the iPhone
iPhone tip of the day: re-ordering your menu pages
Re-ordering menu pages can be a real drag if each have a full set of icons – as when you move the icons around they bump off other icons. So I have an easy solution for you!
Your menu has 4 icons at the bottom which are always on screen, mostly likely thinks like the iPod and Phone apps. The easiest way to reshuffule is to temporarily move those 4 icons off to some unused screen – then use the space to move your apps wherever you like. When you’re done – simply put the original 4 back on and you’re done. :-)
Have you tried turning it off and on again?
iPhone dev tip of the day:
If you get some strange error when trying to run something on your iPhone when it normally works – or if your App (or someone elses) is crashing in an unusual way – reboot your device by holding the power switch.
This normally fixes the dev issue – and for the second? It’s probably memory fragmentation – and this fixes that too. Good idea to reboot the device once every few weeks just to clear out the cruft.
Objective-C tip of the day
Don’t ignore warnings. If you get a warning it’s probably actually an error – things like misspelt methods (i.e. messages) which would be classed as an error in C++/Java/C# are just warnings due to the dynamic nature of Objective-C – and yet are just as bad (your method isn’t being called!)
So fix all your warnings – if the warning actually doesn’t matter – then take steps to remove it anyway so your bad warnings don’t get lost in the mix.
Command-Option-W
in finder will dismiss all finder windows. which is good because they seem to breed like rabbits – and can persist even when you reboot.
Deserializing NSMutableArray
[Ed: this post may actually be totally wrong as in another place I deserialized an NSMutableArray and got it back - so perhaps I had accidently seralized a NSArray by mistake? I'm not sure. Anyway at least it's an example of how to make mutable copies!]
Word of warning just because you serialise a NSMutableArray doesn’t mean you get one back! If you look at the docs it says it conforms to NSCoding but for NSArray – so you actually get a NSArray back.
You need to call ‘mutableCopy’ on it to make it mutable (and be aware that this method retains automatically… gotta love Objective-C).
If you don’t create a mutable copy – your app will crash when you try and add something to the array. You’ve been warned!
