I have a really frustrating error that I've spent hours looking at and cannot fix. I can get data from my db no problem with this code, but inserting or updating gives me these errors: *** Assertion failure in +[Functions db_insert_answer:question_type:score:], /Volumes/Xcode/Kanji/Classes/Functions.m:129 *** Terminating app due to un...
Hello, I have a UIProgressView that I am trying to change the progress but is is never updated. My "slow" operation is done from a NSoperation/NSOperation queue so it should be multithreaded. Did you already experienced this or do you have any idea to solve this? Thanks :) ...
How can I escape a string containing random characters with php for a plist file? htmlentities() seems doesn't seem to be strict enough. For example: <?xml version="1.0" encoding="UTF-8"?><!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <string><?php echo...
Hi all, Just toying with the SDK and I was wondering if possible a UITouch event can work inside a UIScrollView. I have setup a UIScrollView which handles a large UIView, inside the UIView is a UIImageView, I've managed to get the UITouch to drag the UIImageView outside of the UIScrollView but inside it's not registering the event. I ...
For example, when I call a method that returns an value, but I'm not interested in this at all, can I safely ignore that? Example, instead of: CGSize size = [str sizeWithFont:myFont minFontSize:19.0f actualFontSize:&actualFontSize forWidth:150.0f lineBreakMode:UILineBreakModeClip]; ...do this: [str sizeWithFont:myFont minFontSize:19...

Hi, im trying to write an app that will display a list off lines from a book e.g line 1, line 2 in a table view and you can then select a line to view the corrosponding text. I've got to the stage where the text should at least appear in the table view(not as far as being able to select it), yet it remains empty. I used the debugger a...
Basicly iv built my app using a plist. But with the data there is a few times when I need to press return and start a new line. The return key doesn't work in the plist. If I did it the older way it would be \n\n but that doesn't work either. Is there a obvious way I'm overlooking? Or will it be a case off just pressing the space bar al...

I have an iPhone app that uses the json-framework. I moved some of the code, including the json-framework source, from the main project to a static library. When I did this, the json-framework stopped getting compiled into the binary (double checked with class dump). This causes a nasty error: *** Terminating app due to uncaught excepti...
When drawing OpenGL ES textures, they seem to "snap" to round pixel locations, as though the draw location was being rounded. ie. drawing at (x:1.1, y:5.4) actually draws at (x:1, y:5). This causes the textures to appear to "jump" when scrolling, rather than move smoothly. Yes, I'm using floating point types for my vertices, etc. D...
Hi, I currently have a custom UITableViewCell which contains a few labels, and an image. The "main" label is used to display people's names. Currently, I'm styling it in bold text. What I'd like to do (to gain some space and readability), is to mimic the Address Book app cell style, that is: first name in light text, and family name in ...

I am writing an app that caches streaming content from the web on the iPhone. Right now, I'm saving data to disk as it arrives (in chunk sizes ranging from 1KB to about 60KB), but application response is somewhat sluggish (better than I was expecting, but still pretty bad). My question is: does anyone have a rule of thumb for how freque...
