Greetings! I know that UITableView sectionHeaderHeight is only used for grouped tables, but I'll ask anyway (in case there's some way to do this that isn't obvious) ... Is there a way to change the section header height (and with it, the font/size) for a NON -grouped table? Hoping "yes" or at least a "maybe" ... but fearing it might be a "no". Have at it, folks. Yes. Use this delegate method: - (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section { return 44; } Of course, change as appropriate. There's of course the one for footer as well: - (CGFloat

I have this part of code: NSDate *date =nil; NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setDateStyle:NSDateFormatterMediumStyle]; [dateFormatter setDateFormat:@"dd-MM-yy"]; date = [dateFormatter dateFromString:inString]; [dateFormatter release]; It works perfectly fine, as expected in iOS 4.0. But the same code doesnt in 3.0. The string which I am getting, is like "12-Nov-10" and this is contained in inString pointer. The date formatter returns nil if the native OS is 3.0 or 3.1. For some reasons I need to stick to the same date format. Has anyone else

In my Core Data Model i've got an entity that has a date attribute and as the title suggests, i'd like to group this entity by (week)days. The problem is, the dates are stored more or less as timestamps and i don't know how to create a predicate that is capable of grouping/filtering my entities approprioately. I've figured out that i will probably have to do a fetch for each day, so created following method. The code were i need help with is right in the middle of it. - (NSFetchedResultsController *)fetchedResultsController:(NSDate *)day { if(fetchedResultsController != nil) return

I finally landed up in developing an iPhone app using Titanium Mobile. Now the problem I face is, Im able to run the app, and the app also sends the image to the server. But Im not able to see the file that got uploaded to the server. I have pasted the iPhone app's code to send image to the server and also, the PHP file that would receive the file from the app. var win = Titanium.UI.currentWindow; var ind=Titanium.UI.createProgressBar({ width:200, height:50, min:0, max:1, value:0, style:Titanium.UI.iPhone.ProgressBarStyle.PLAIN, top:10, message:'Uploading Image', font:{fontSize:12, fontWeight:

I'm doing some math on both gyroscope and accelerometer data combined and I'd like to low pass filter the resulting data. So could someone post some generic code for a Low Pass filter? A 1st order IIR low-pass filter can be of the form: output_value = rate * input_value + (1.0 - rate) * previous_output_value; which is pretty much what's inside Apple's AccelerometerGraph example. You select the rate parameter depending on what frequency (very very roughly shakes per second) you want to roll-off or start to attenuate to get a smoother resulting output, and the sample rate of the input data. A

I have 10,000 rows in database table. I have a view which is suppose to list all these rows in a tableview. But loading all in one shot takes ages to appear in tableview. How can we use "Load More Records" feature which will fetch 20 records at a time? If user wants to view more entries, they can click "Load More Records" button and it will show next 20 records. Will have to modify my select statement? What other changes do I have to do to achieve this? UITableView reuses its cells. This means you can dynamically access your database when cellForRowAtIndexPath: is called- you don't need to

This is a followup to a previous question on cross-compiling for the iPhone: Cross-compile Autotools-based Libraries for Official iPhone SDK Basically, I am trying to compile the Apache Portable Runtime (APR) version 1.3.8 (latest) for the iPhone. I am currently running into the following error during the configuration step: checking for working PROCESS_SHARED locks... configure: error: in `/Users/michaelsafyan/Downloads/apr-1.3.8': configure: error: cannot run test program while cross compiling See `config.log' for more details.
