  • How to figure out if two CGRect intersect?

    - by mystify
    In -drawRect: I want to check if the provided rect intersects with anotherRect. I'm not good at this geometry math stuff and especially at english so what I want to say is: If you have two sheets of paper on the desk, and one of them covers the other either completely or just a small portion, it is rectsIntersect = YES. How to check that out for rect and anotherRect?

  • living column in instruments

    - by dubbeat
    In the context of allocations what exactly does the living column mean? Does it mean the number of times an object was created or does it mean how many instances of an object there is? I ask because I'm testing going in and out of a view. When I enter the view I create a class "myClass". When I exit the view I nil "myClass" and release it. If I go in and out of the view 6 times for example the living column in instruments for "myClass" says 6. Is this normal or is it not being released properly?

  • I want to crop an image, draw a smaller size image without caching the images.... What is the best w

    - by rkbang
    Hello all, I am storing the images in database. I get the NSData and create an image from it. Now I want to crop or draw a smaller image of the existing image in database which I am getting from the querry. I dont want to cache the images since I am using them in bulk and want to release them as soon as the view being displayed where the images are used is popped up. Is there any efficient solution to make sure that images dont consume memory at the background once their use is over... I will appreciate the lines of code for this. Tnx in advance.

  • iPad: How can I implement a scrolling timeline using a static image?

    - by BeachRunnerJoe
    I'm diving into iOS development and I'm building a simple timeline app using a static timeline image that I already have. The timeline image won't fit on the screen. The width of the image is about five times the width of the iPad screen, so I have to allow the user to scroll the image horizontally. Here's a mockup... For each item on the timeline, the user can tap it to receive a description at the bottom of the screen. My questions are... I was planning to use a UIScrollView with a PageControl at the bottom. Can a UIScrollView hold a single view that holds the entire timeline image or do I have to break the the timeline image up into multiple views? Are there any performance issues I need to consider when implementing this with a UIScrolLView, using a static image? Are there other approaches to implementing this scrollable timeline that I should consider other than using a UIScrollView? Thanks so much in advance for your wisdom!

  • Static keyboard in uitableview

    - by Martin
    I have a UITableView that holds just two cells with a textfield in each. As my tableview is just for editing the text in these textfields I always want the keyboard to be shown static in the bottom of the screen. So in viewDidLoad I set the first textfield to become first responder. Something I have noticed though is that when I push the UITableViewController into the UINavigationController the keyboard show up a little bit slower so you can see it animate into the screen. It would be much better if it was there already there when the uitableview shows up. I also tried making the textfield first responder before pushing it as recommended but that didn't made the keyboard show at all: MyTableViewController *myTableViewController = [[MyTableViewController alloc] initWithNibName:@"MyTableViewController" bundle:nil]; [myTableViewController.textField becomeFirstResponder]; [self.navigationController pushViewController:myTableViewController animated:YES]; [myTableViewController release]; How can I accomplish this? Thanks!

  • UITableView with multiple selections

    - by NewDev
    I have a UITableView with multiple selections enabled. If I select items and scroll the list back and forth they are remembered and shown and selected (blue background). Using the didDeselectRowAtIndexPath and didSelectRowAtIndexPath I am able to keep my own array of selected items. That part works well. However, if I then use the sectionForSectionIndexTitle and jump to a letter, the selection appears to be forgotten - even indexPathForSelectedRows appears to have been reset and is now empty. My own array remembers that an item is selected and I can set the cell.selected in the cellForRowAtIndexPath but the instant I move the list it is forgotten again. Any ideas? Is this a bug, or how do you retain the selection list when jumping to a letter?

  • How do I reference a pointer from a different class?

    - by Justagruvn
    First off, I despise singletons with a passion. Though I should probably be trying to use one, I just don't want to. I want to create a data class (that is instantiated only once by a view controller on loading), and then using a different class, message the crap out of that data instance until it is brimming with so much data, it smiles. So, how do I do that? I made a pointer to the instance of the data class when I instantiated it. I'm now over in a separate view controller, action occurs, and I want to update the initial data object. I think I need to reference that object by way of pointer, but I have no idea how to do that. Yes, I've set properties and getters and setters, which seem to work, but only in the initial view controller class. Peace Love applesauce.

  • UiScrollView with scrolling content

    - by objektivs
    I have a detail page of type UIScrollView. On it I want an optional UIImageView and a mandatory UITextView. If no image is available then the image view should not take any space. The text for the text view can be of varying sizes. When the view is loaded with, say, the image and the text I need to be able to scroll through all the contents. So the image slips off the top of the screen. I just can't get this work and I feel it ought to be easy. Any ideas?

  • Obj-C: Creating an object with a String name

    - by FnGreg7
    Hey all. I know this sounds simple, but I can't find a way to do it. I have a method in Obj-C that takes in a NSString and then should create a new class with the String as its title. -(DataModel *)createDataModel:(NSString *)dataModel_name { DataModel *[initWithString:dataModel_name] = [[DataModel alloc] init]; } I know I have some problems in this. For starters, I don't know how to define a return on an object whose name could change. Second, I know this doesn't compile considering the initWithString method is wrong. I just don't know what to do or what method to use so that I can create this DataModel object with the specified name...

  • Can a method return an NSRange?

    - by Dan Donaldson
    I have a method that returns an NSRange. When I call this method from outside the class I get a compile error. NSRange tmpRange; tmpRange = [phrase rangeInString:searchString forString:theLetter goingForward:YES]; return tmpRange.location == -1; in the .h file: #import <Foundation/Foundation.h> @interface Phrase : NSObject { } - (NSRange) rangeInString:(NSString *) tgt forString:(NSString *) find goingForward:(BOOL) fwd; @end This method is called within the Phrase object by other methods without problems. The compiler says 'incompatible types in assignment'. Can anyone explain this to me? I assume it has to do with returning an NSRange/struct type value generated outside the object, but I don't know why it works in one place and not the other.
