This question is similar to this one, but hopefully it will pick up some more interest due to me having tried some stuff. I am trying to do standard pinch-pan scrolling in a UITextView. My delegate implements UITextViewDelegate and implements this method - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView { return sel...
I'm trying to use [[NSCalendar currentCalendar] ordinalityOfUnit:NSDayCalendarUnit inUnit:NSEraCalendarUnit forDate:date] on two different dates to see if they fall on the same day. However, if my time zone is different (say, somewhere in Germany), even though the dates are obviously the same, the days returned are different. If I use ...
I have a UIImagePickerController that lets the user pick an image from their library, edit it, and then save the product out to disk. Before it saves, however, I need to update a UIImageView to hold the edited photo. But when I go to set the UIImageView's image property, the program crashes. It still can save to disk. The UIImageView is...
Hi, I have been searching for days on this topic and cannot come up with a straight answer on how to cut down on the launch time of my app. Can anyone take a couple minutes to interpret this crash log for me (or teach me how)? Cuz I have no clue and I have tried searching and even contacting Apple. Thanks so much in advance. This fo...

We are an iPhone Developer Program member. We've got a DUNS number but not the 500 employees necessary to join the iPhone Developer Enterprise Program. Therefore I can can't see how things exactly operate for the Enterprise level. But we have customers that are big enough to be Enterprise developers and we could distribute our applicatio...

I have just upgraded to xcode 3.2.3. When I build and run the app, the simulator is not updated with the latest app build. Anyone knows why this has changed in this new release of xcode. If it is it's a shame as the environment is not as productive as it used to be, having to delete the app file each time in finder. Any ideas? ...
Hi guys, This one has been driving me nuts... Considering "plane" is a CALayer, I rotate it in the X axis: plane.transform = CATransform3DMakeRotation(180 * M_PI / 180.0f, 1.0f, 0.0f, 0.0f); And this makes it rotate clockwise, which is perfect. Now, at some point in time, I want it to return to 0 degrees, so I use: plane.transform...
Hello, I'm interested in loading indexed-color PNG images in my iPhone application. Once they're loaded, I want to access the images on a per-pixel basis. In particular, I want to get the index of the color (rather than the color itself) of individual pixels. Unfortunately, there does not seem to be a way to access pixels via the UIIma...

I am sorting the UITableView by using a predicate with NSFetchedResultsController. But, when I make a change in a detail view and save it, the object I changed immediately gets placed in its new location in the UITableView. I have up/down buttons similar to the message view in Mail. This behavior disrupts the ordering of items, and I'd ...

Hi, I'm working on setting up NSDateFormatter to explain the date, and I'd like something short but more intuitive than 15/07/10. I think I've seen some formats that will say simply "Today" or "Tomorrow" or the day of the week for subsequent days of the same week. Is there a simple apple-approved way to get this type of date? Thanks. ...
