问题 I don't know too much information about didReceiveMemoryWarning but considering what I read on other posts and looking for in the documentation, I've seen that in case of iOS 5, any non-visible view controller will dump its view, but in case of iOS 6 the documention (documentation says that the default implementation "exits" and I don't know exactly how I should understand that. I've been doing some tests with the iOS Simulator simulating a low-memory warning, and I appreciate (on iOS 5) that

问题 One of the new ios6 classes is uicollectionview which allows one to display items in a grid format similar to the Homescreen / iBooks / Pages layout. Is there was a way to receive a touch event on a button that is on the UICollectionViewCell? Currently, my cell is created through an XIB file and added to the UICollectionView programatically.

问题 I'd like to add a scrollview to my project. I've added the following code in my file: - (void)viewDidLoad { [super viewDidLoad]; [scrollView setScrollEnabled:YES]; [scrollView setContentSize: CGSizeMake(320, 830)]; } This works good with xcode 4.3 und IOS 5.

The layout in iPhone 5 looks good. What should I do, when I want don't

The code subclasses UIView and runs fine on the Simulator (both for iOS 5.1 and iOS 6.0). Circle.h #import <UIKit/UIKit.h> @interface Circle : UIView @end Circle.m #import "Circle.h" @implementation Circle -(CGPathRef) circlePath{ UIBezierPath *path = [UIBezierPath bezierPath]; [path addArcWithCenter:self.center radius:10.0 startAngle:0.0 endAngle:360.0 clockwise:YES];
