//iOS 7 스토리보드 대신 xib 방식으로 개발하기

//solution 1

1. empty application 생성
2. new class file 생성 -> name : ViewController, UIViewController sub class, with XIB check
3. appdelegate 헤더 파일 수정

//two ways of making UITableView Cell

//ex
//1. much simpler
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
	UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    
    // Configure the cell...

//delegate pattern 

//delegate pattern is commonly used to handle the following situation
//ex)
//screen A opens screen B and at some point screen B needs to communicate back to screen A, for example when it closes. 
//The solution is to make A a delegate of B so screen B can send its messages to A whenever it needs to.

//Screen A launches screen B and becomes its delegate
//The cool thing about the delegate pattern is that screen B doesn’t really know anything about screen A. 
//It just knows that some object is its delegate. Other than that, screen B doesn’t care who that is. Just like UITableView doesn’t really care about your view controller, only that it delivers table view cells when the table view asks for them.

//If the item object has its checked property set to NO, increment the local variable count by 1
//When looked at all the objects, return the value of this count to the caller

assign and copy properties

Property with ’retain (or strong)’ attribute must be of object type

so, declare a property as assign if it has a primitive value 
@property (nonatomic, assign) int someNumber;

You also use assign for structs, because they aren’t objects either 
@property (nonatomic, assign) CLLocationCoordinate2D coordinate;

//making basic UICollectionView

//UICollectionView 주요 메소드 (UITableView와 비교)

//UICollectionView vs UITableView 
//Item(Cell) 갯수(필수)
 - (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section
 - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
 
//Item(Cell) 꾸미기(필수)
