Make the UITableView with group style to round the image.

The point is, the roundCorner is draw by a subview of UITableViewCell, and mean while, it's not a public class, there is no way you can get layer.cornerRadius from any view. So we need to resolve this problem by ourselves.

There are 2 cases.

  1. There is only one cell.

    This case is ease, just use cell.contentView.layer.cornerRadius and cell.contentView.layer.masksToBounds to make it work.

  2. There are more than one cell.

Use bundleForClass to get the unit test bundle's path

// iOS app is an executable bundle, means the `main` method is
// included inside app bundle, so `mainBundle` returns the app bundle

NSOrderedSet does not work well on insert

Usually, we generate an entity class with Editor->Create NSManagedOBject Subclass... For example we created a subclass of NSManagedObject

Xcode generates the .h file like this:

@interface MyEntity : NSManagedObject

@property (nonatomic, retain) NSOrderedSet manySubs;

//... some methods generated by Xcode

using KVC on collection objects like NSArray and NSDictionary.

KVCを使えば、このようなコードが自動的に値を計算してくれる。

KVC with special keyPath is really powerful for collection objects like NSArray and NSDictionary and NSSet

@max, @min, @sum, @avg

Sample 1 : One of the element in the array does not contain height property
