the update status button text does not change when clicked. I know the event is being fired because the text in the status text line does indicate the proper values, just the toggling of the button text does not work….

any ideas?

Three questions -

1) How do I add a login page to be first page displayed on this application? Just a simple view with a graphic, a text entry field and a button. The button click will bring up the tutorial entry point?

2) When the item list is first displayed, the icons and priority are correct (as in database) but when I look at item, change priority, then return to item list, the icons for the priority are all green dots?

3) When I deploy the application to my iTouch, if i leave the debug code section in, the app works… if I set it to release, the app will not show the detail view of the data.

Thanks for a fantastic tutorial!!

take care
tony

You always find your errors after you ask the question.

I’m getting a compile error in RootViewController.m – “TodoCell” undeclared.

Everything compiled just fine until this point.

“Todo.h” and “TodoCell.h” have both been included.

Any thoughts?

Yes, NSLog() will help you. for using that, you have to write

#define DEBUG

after import part by file todoAppDelegate.h

Hope my infomation could help somebody.

I’ve been following your tutorials and all have been really useful. Thanks a lot for sharing them.

I’m having issues with this particular one: has no errors but doesn’t display anything…

I download then your code. I run it and… same thing.

Have you got any idea what is this happening?

Thanks in advance.

The errors are:
error: expected specifier-qualifier-list before ‘Todo’ (line 13: Todo *todo;)
error: expected ‘)’ before ‘Todo’ (line 25: -(Todo *)todo;)
error: expected ‘)’ before ‘Todo’ (line 26: -(void)setTodo:(Todo *)newTodo;)

Can anyone help? I am using the code sample code from this site, so I don’t understand what could be wrong. Thanks

todoPriorityLabel

with

todoTextLabel

initWithFrame:reuseIdentifier:

Initializes and returns a table cell object. (Deprecated in iPhone OS 3.0. Use initWithStyle:reuseIdentifier: instead.)

That is in file TodoCell.m:32

How do I need to change that?

UIFont boldSystemFontOfSize:fontSize

I am on Xcode 3.2.1

I also get No -’initWithPrimaryKey:database:’ method found.

But as said: it still compiles and installs. Then it just crashes on the Simulator.

I had the same problem, Txs for the solution. I got the next error in RootViewController.m

with Finally, the method it was solved:)

If I run your sample code, it works no problems. So my guess is it’s something to do with the SDK version of either the iPhone or SQLite. I checked the reference for SQLite, and we’re both pointing to libsqlite3.0.dylib.

When I highlight the library reference and click the info button in the toolbar, I see that your library path is the same as mine (usr/lib/sqlite3.0.dylib), but the full path is different. Your path is rooted in my downloads directory under the downloaded project directory name, then iphoneos2.0/usr/lib/sqlite3.0.dylib, and mine is rooted in developer/platforms/iphoneos.platform/developersdks/iphoneos3.1.2.sdk/usr/lib/libsqlite3.0.dylib.

I have the downloaded code set to compile against simulator 3.1.2; the same as my follow-along project, however the reference appears to be against a different version of the library. I would expect if we’re compiling against the same version of the SQLite library, that the API wouldn’t have changed, but that’s the only thing I can thing of – that there’s a missing call before the prepare in the version of the library I’m working against?

I’m new to the Mac, and iPhone programming. I hope this can be useful to yourself or one of your readers. I’ll keep digging in the meantime, and post if I find an answer first.

Thanks for the great tutorials. They’re easy to follow and quite informative.

Am I missing something?

I have a “_TERMINATING_DUE_TO_UNCAUGHT_EXCEPTION_” error when it reaches the line ” [cell setTodo:td]; ”
not sure what is wrong.

Thanks,

I want to thank you again for these wonderful tutorials. After much pain and time attempting to add a navigation controller to my existing project I decided to start with a new project and one of your earlier tutorials. I will then add my existing code to it. Once again thanks as I have read many of Apple’s sample projects and it is your screen shots and how to use Xcode and Interface Builder that makes any of their code useful.

Thanks for the awesome tutorial Brandon.

I like to work thru problems. Having said that, I approached this tutorial w/ a twist of using my own variables rather than what the tutorial used – that way, I have to work to fix the compile/run-time errors.

I called the database sql_todo.sqlite, but used the same table name as in the tutorial (todo) when populating it; but in the code I used sql_todo for the “select” statement. Because of this, no data was shown in the simulator. After I fixed the code, the simulator shows data – but the format is not what the tutorial shows.

1. The priority label is on the right side (over-writes the text of the to-do list)
2. The priority images are not shown at all.

I have checked the code and the #defines in the layoutSubviews() method. I am still scratching my head.

Any pinters? Thx in advance!

I followed your todo example but modified it a bit, instead of using an sql to retrieve the data, i used an array just like in the fruits example. however, im am getting an error “_TERMINATING_DUE_TO_UNCAUGHT_EXCEPTION___”. Also, there’s a warning on the property for the three todoCell data (todoTextLabel..), “requires method setTodoTextLabel to be defined – use @synthesize, @dynamic or provide a method” though I synthesize it as describe in your tutorial.

Could you please provide me some code on how to do this using array instead of accessing the database?

thanks,
Wilbert
