• Which icons/buttons to use for help, about, info?

  - by 4thSpace

  I use the info button to display a settings page. This page is a modal. I need another button from here to display "About" info, since I've already used "info" for something. I have a search form that is accessed only from the modal. On the search form, I need a help icon. I can use the info button but that seems confusing, since I already use the info button from the main view to access the modal. What else can I do for help and about icons/buttons?

• iphone app working on most devices but not a few

  - by Matt Facer

  Hi there. I have recently been rewriting some of my iphone app because a couple of users have said it was crashing on certain events. The event in question is when I add a new XIB to the view using the following code AddItemViewController * add_item = [[AddItemViewController alloc] initWithNibName:@"AddItem" bundle:[NSBundle mainBundle]]; [self presentModalViewController:add_item animated:YES]; [add_item setViewFormat:2]; [add_item release]; it works perfectly on my iphone and a mate's ipod touch (both running 3.1.3) but another user on an ipod touch also with 3.1.3 says it crashes when the function above is called. Why could this be happening? Surely if it works on one device it should work on another?! Is there a better way to add a view which maybe doesnt crash? I have also disabled all the code on the loading xib - so it literally is loading a near blank page. It's SO annoying!! Thanks for any help.

• Do something when phone reaches a set of location?

  - by Pentium10

  I have a list of coordinates in the database identified as POI. For a city could be 100 records. I would like to get notified when the phone gets in 150 meters range of one of the location. The location coordinates too has an error/radius, usually 10 to 100meters. Since I don't find it good to add each location(could be hundreds) for a trigger, how can I optimize the wake-up code? Also do I have options to remove a previously setup notification from the queue?

• Can I use Google Drive's editor interface embed in a website?

  - by Zamith

  I want to use google drive to store the files, but allow the users of my website to be able to edit them transparently, so that they don't have to go to google drive's website. Is this possible with the current API? Thus far I have only seen how to create an app for them to install in google drive, or doing something like DrEdit (https://developers.google.com/drive/examples/), which parses the files to JSON and uses the ACE editor, which is definitely not what I want.

• What options I have to show a sentence parts with different color?

  - by Pentium10

  I have a longer sentence 200 characters. I need to show on the screen having parts of them in different color, like highlighting search results, each with different color. The text should auto wrap with screen width, and have no break sections between parts. I meant with this that I can put sections on a new line. They will have to continue the previous section, only wrap when the screen is off. The best would be an EditText, as I need to allow editing also, but I am wondering I am able to change the color of various sentence parts, or just as a whole. What do you think, with what UI elements can I achieve this view?

• iOS Display Different Image on Click

  - by user1506841

  Using XCode, I am trying to figure out how to display a different image when someone clicks or presses down on one of my buttons before being taken to a second screen. For example, I have a contact icon on my home screen. When a user clicks the icon, it should change to a darker version on tap before going to the contact screen. Any help is appreciated. -(IBAction) ButtonPressed :(id)sender { UIButton *tempButton = (UIButton *) sender; int tag = tempButton.tag; NSString *viewName; switch (tag) { case 1: [FlurryAnalytics logEvent:@"Contact-Screen"]; viewName = @"ContactScreen"; if( self.appDelegate.sound) [Click play]; [self.appDelegate moveToView:viewName]; break; } }

• How to add a UIView above the current UITableViewController

  - by user558096

  I'm have difficulty adding a subview UIView from within the viewDidLoad method of a UITableViewController This works: [self.view addSubview:self.progView]; But you can see the table cell lines bleed through the UIView progView. I've tried this approach: [self.view.superview insertSubview:self.progView aboveSubview:self.view]; Which is an attempt to add the progView UIView to the superview, above the current view. When I try this I get this the UIView never appears.
