(Objective C) How to find the distance between two CG points? - espinallab

Wed, 25 May 2011 08:18:31 UTC

Distance between p1 and p2: CGFloat xDist = (p2.x - p1.x); CGFloat yDist = (p2.y - p1.y); CGFloat distance = sqrt((xDist * xDist) + (yDist * yDist)); Background: Pythagorean theorem Edit: if you only need to calculate if the distance between the points increases or decreases, you can omit the sqrt() which will make it a little faster.

(Objective C) UIActionSheet cancel button strange behaviour - espinallab

Wed, 05 May 2010 10:51:45 UTC

01-Dec-2008 10:22 PM Tom Saxton: I looked at this bug some more, and it seems to be an issue with the tabbar. If you call UIActionSheet's [sheet showInView:self.view] from a view controller that is a child of a UITabViewController, then the hit testing on the cancel button fails in that portion of the UIActionSheet that lies above the tabbar's view. If you instead pass in the UITabBarController's view, then the UIActionSheet acts as expected. NOTE: in iPhone OS 2.1 and earlier, the UIActionSheet came up from the top of the tab bar when you pass the child view, but in 2.2, it comes up from the bottom of the tab bar, and thus covers the tab view.

This works well for me, and doesn't appear to have issues with pushing new view controllers, hidden titles and bar button items, etc. To implement it just copy and paste this line before you ViewController @implementation file. Example: // // MenuViewController.m // Restaurant // // Created by Eddie on 4/10/10. // Copyright 2010 __MyCompanyName__. All rights reserved. // #import "MenuViewController.h" #import "CheckoutViewController.h" @implementation UINavigationBar (CustomImage) - (void)drawRect:(CGRect)rect { UIImage *image = [UIImage imageNamed: @"grayGB.png"]; [image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)]; } @end @implementation MenuViewController @synthesize tableView, menuArray;

This tutorial will go over the HTML post.
