What is the view used to create the Template Chooser view in the iWork apps on iPad? How can I create a view like that on iPad, and what would be a best way to implement it on iPhone considering screen size constraints. ...
I'm having an issue with drawing to areas outside of the MKMapRect passed to drawMapRect:mapRect:zoomScale:inContext in my MKOverlayView derived class. I'm trying to draw a triangle for each coordinate in a collection and the problem occurs when the coordinate is near the edge of the MKMapRect. See the below image for an example of the...
I'm trying to create an iPhone app with a welcome screen that leads to two or three pretty disparate UIs; once you've drilled into one you're not going to have much use for the others, and each one is itself fairly complicated. The designers are all web types and it looks like the "navigation" paradigm is the closest to what they want, ...
Hi! I'm starting to develop a simple application for iOS, and this application is a simple gallery of some photo (taken from a website). The first problem I encountered is how to create the view for the gallery. The view should be something like this (or the Photo App): however doing a view this way is problematic, first because it us...
I have an iPad specific application running iOS 3.2.2 which displays a settings view in a ui popover. This all renders great, but now I'm trying to get a date picker to render inside the view and not sure what the best approach is for displaying it. Right now it has a button which toggles visibility of the date picker within the modal,...
I have a uitableview within a navigation controller shown within a popover. When you press a bar button from within the popover (on a detail view), it shows a modal view. If you rotate the iPad with the popover visible and the modal view on top of that, the popover's content changes to a seemingly random orientation as shown below. Any ...
Trying to create a simple table full of buttons, where the buttons are generated at run-time; the table appears, and has the right number of rows etc., but the rows appear to be empty. public override UITableViewCell GetCell (UITableView tableView, NSIndexPath indexPath) { // The NavItem class is a "Josh Bloch enum" with...
What is the best way to run code on a separate thread? Is it: [NSThread detachNewThreadSelector: @selector(doStuff) toTarget:self withObject:NULL]; Or: NSOperationQueue *queue = [NSOperationQueue new]; NSInvocationOperation *operation = [[NSInvocationOperation alloc] initWithTarget:self ...
I have added a few buttons to the right side of the navigation bar with the following: UIView* customView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 44)]; customView.backgroundColor = [UIColor clearColor]; UIButton* button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(0, 0, 45, 44); button.conten...
How hard would be be to recreate Windows Phone 7 UI animations on an iOS device using UIKit? More specifically, making animated boxes gradually move from side-to-side, and appear in a chained manner. For example, windows phone 7 transitions here: http://www.youtube.com/watch?v=EUeNCzRhhDE At 0:30 - the parallax scrolling effect (relati...
Hello, I'm a beginner at iPhone developing. Though I've read lots of guides and users' notes I have no exact and accessible answer to the following question: "Are there any ways to execute internal tasks (or for example to listen for server activity) in background in iOS 4.x?" I know that only 3 kinds of tasks are permitted (audio, vo...
Does anyone know how to get the NSDate of the coming friday's 20:00 ? ...
Hi, as a background: I am developing an application for the iPad where users can browse videos that are provided by us. When a user picks a video it will then launch an MPMoviePlayerController - which works fine (besides I get no video for the first 10 seconds, of which I have no idea why). Now, users should be able to search for speci...
I need to exit my app while my app enter into background ...
Hi all, When we draw 300 sprites on the iPad using opengl 2.0 with glEnable(GL_BLEND) (which we need because the sprites need tranparency and alpha blending) we get an framerate of around 40. But when we disable the blending we get an framerate of 60. Now is (alpha) blending really that costly or are we doing something wrong? Thanks f...
I'm trying to send an NSString as an attachment using MFMailComposeViewController. When I open the Mail I just have a "Part 1.2" Attachment. Here's the code used: MFMailComposeViewController* controller = [[MFMailComposeViewController alloc] init]; NSMutableString* writtenWillItBe=[NSMutableString stringWithFormat:@"...",...]; [contro...
New to iOS, coming from the Java / Swing world, where I'm used to creating UIs programmatically, letting components size themselves and using various clever layout managers to arrange things. It already seems clear that the iOS way is to make heavy use of Interface Builder, with a lot of fixed sizing and positioning. I'm not sure IB is ...
I have an iPhone app with a main view that has a UILabel and a UIButton. When the button is clicked, I display a second view. The second view has a text box and an OK button. I want the user to enter something in the second view's text box and then click the OK button; this should close the second view and apply the entered text to th...
It seems most reading application that will display quite a lot of text will still use WebView instead of Core Text (Instapaper, iBooks, other reading apps). I want to know if there are any concerns for those applications not using Core Text but WebView which will generally have rather poor performance. ...
I'm making an app that is kinda like iBooks. There is some stuff on the screen, each item represented by a small thumbnail. I want the user to be able to delete the items much like when you tap the "Edit" button in iBooks - an X comes up, and the item is deleted. I'm using the delegation pattern to handle all of this, so here is some cod...
