Navigation Bar
Bar Button Itam 做ㄧ個新增的方法

呼叫被刪除的指令

-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{

}

這時候只會出現動作而已
當結合下方的指令才會產生結果

switch (editingStyle) {
        case UITableViewCellEditingStyleDelete:
            break;
        case UITableViewCellEditingStyleInsert:
            break;
        case UITableViewCellEditingStyleNone:
            break;

        default:
            break;
-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
switch (editingStyle) {
        case UITableViewCellEditingStyleDelete:
             [self.history removeObjectAtIndex:indexPath.row];
            [tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
            break;
        case UITableViewCellEditingStyleInsert:
            break;
        case UITableViewCellEditingStyleNone:
            break;

        default:
            break;
}

OBJ-C在switch裡面只能判斷數字
使用C語言的ENUM來判斷
UITableViewCellEditingStyleDelete:
UITableViewCellEditingStyleInsert:
UITableViewCellEditingStyleNone:

開一個類別GuessViewController在Controller資料夾
在.m裡面實作方法

#import "GuessViewController.h"

@interface GuessViewController ()

@end

@implementation GuessViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
}

-(void)randomNumber{
    NSArray *arrey=@[@0,@1,@2,@3,@4,@5,@6,@7,@8,@9];
    NSInteger index = arc4random() %10;
    NSset
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

/*
#pragma mark - Navigation

// In a storyboard-based application, you will often want to do a little preparation before navigation
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    // Get the new view controller using [segue destinationViewController].
    // Pass the selected object to the new view controller.
}
*/

@end

然後加入這個方法在viewDidload方法下方

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
}

-(void)randomNumber{
    //產生隨機數字
    NSArray *array=@[@0,@1,@2,@3,@4,@5,@6,@7,@8,@9];
    NSMutableSet * picked = [[NSMutableSet alloc] init];
    while(picked.count !=4){
        NSInteger index = arc4random() %10;
        NSNumber*unit = array[index];
        [picked addObject:unit];
    }

    NSArray * answer = [picked allObjects];
    NSLog(@"%@",answer);
}

//取得文字框的字
-(void)getUserGuess{
    NSString * userGuess=self.playTextfield.text;
    NSInteger guessNumber= userGuess.integerValue;
}

這裡有兩種方式可以寫抓取四位數字

方法1

  NSInteger* thousand = guessNumber/1000;
    guessNumber %=1000;
    NSInteger *hundred = guessNumber/100;
    guessNumber %=100;
    NSInteger *ten = guessNumber/10;
    guessNumber%=10;
    NSInteger *unit =guessNumber %10;

方法2

 NSNumber *thousand=[NSNumber numberWithInteger:(guessNumber/1000)] ;
    guessNumber %=1000;
    NSNumber *hundred =[NSNumber numberWithInteger:(guessNumber/100)] ;    
    guessNumber %=100;
    NSNumber *ten = [NSNumber numberWithInteger:(guessNumber/10)] ;
    guessNumber %=10;

要記得去main storyboard 設定GuessViewController類別
在開始寫

@property (weak, nonatomic) IBOutlet UITextField *playTextField;

- (IBAction)getResult:(UIButton *)sender {
    [self randomNumber];
    [self getUserGuess];

}

-(void)randomNumber{
    //產生隨機數字
    NSArray *array=@[@0,@1,@2,@3,@4,@5,@6,@7,@8,@9];
    NSMutableSet * picked = [[NSMutableSet alloc] init];
    while(picked.count !=4){
        NSInteger index = arc4random() %10;
        NSNumber*unit = array[index];
        [picked addObject:unit];
    }

    NSArray * answer = [picked allObjects];
    NSLog(@"%@",answer);
}

//取得文字框的字
-(void)getUserGuess{
    NSString * userGuess=self.playTextField.text;
    NSInteger guessNumber= userGuess.integerValue;
    NSNumber *thousand=[NSNumber numberWithInteger:(guessNumber/1000)] ;
    guessNumber %=1000;
    NSNumber *hundred =[NSNumber numberWithInteger:(guessNumber/100)] ;
    guessNumber %=100;
    NSNumber *ten = [NSNumber numberWithInteger:(guessNumber/10)] ;
    guessNumber %=10;
    NSNumber *unit =[NSNumber numberWithInteger:(guessNumber%10)] ;

    NSArray * guessArray = @[thousand,hundred,ten,unit];
    NSLog(@"%@",guessArray);
}

改成全域變數以後
讓button可以取用輸入框的變數和隨機產生的變數
然後利用NSMutableSet進行比對

#import "GuessViewController.h"

@interface GuessViewController ()
@property (weak, nonatomic) IBOutlet UITextField *playTextField;
@property (strong, nonatomic)NSArray*guessArray;
@property (strong, nonatomic)NSArray*answer;

@end

@implementation GuessViewController

- (void)viewDidLoad {
    [super viewDidLoad];
        [self randomNumber];
    // Do any additional setup after loading the view.
}
- (IBAction)getResult:(UIButton *)sender {
//    [self randomNumber];
    [self getUserGuess];
    NSMutableSet * answerSet = [NSMutableSet setWithArray:self.answer];
    NSMutableSet * userSet = [NSMutableSet setWithArray:self.guessArray];
   [answerSet intersectSet:userSet];

    NSLog(@"%@",answerSet);



}

-(void)randomNumber{
    //產生隨機數字
    NSArray *array=@[@0,@1,@2,@3,@4,@5,@6,@7,@8,@9];
    NSMutableSet * picked = [[NSMutableSet alloc] init];
    while(picked.count !=4){
        NSInteger index = arc4random() %10;
        NSNumber*unit = array[index];
        [picked addObject:unit];
    }

    self.answer = [picked allObjects];
    NSLog(@"%@",self.answer);
}

//取得文字框的字
-(void)getUserGuess{
    NSString * userTyped=self.playTextField.text;
    NSInteger guessNumber= userTyped.integerValue;
    NSNumber *thousand=[NSNumber numberWithInteger:(guessNumber/1000)] ;
    guessNumber %=1000;
    NSNumber *hundred =[NSNumber numberWithInteger:(guessNumber/100)] ;
    guessNumber %=100;
    NSNumber *ten = [NSNumber numberWithInteger:(guessNumber/10)] ;
    guessNumber %=10;
    NSNumber *unit =[NSNumber numberWithInteger:(guessNumber%10)] ;

    self.guessArray = @[thousand,hundred,ten,unit];
    NSLog(@"%@",self.guessArray);
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

GUI

Navigation Bar
Bar Button Itam 做ㄧ個新增的方法

Syntax
NSSet 無序（沒有順序的）
NSMutableSet
NSMutableSet * answerSet = [NSMutableSet setWithArray:self.answer];

[answerSet intersectSet:userSet];

NSNumber *unit =[NSNumber numberWithInteger:(guessNumber%10)] ;

IOS GCD多執行緒

IOS GCD多執行緒 GCD 簡稱 Grand Central Dispatch ，利用在CPU（雙核，多核心的平行運算）， 自動管理Thread的Liftcycle ，（創造執行緒，調度Task，消除執行緒），不用自己管理Thread。 GCD Objectivc-C 使用Block Swift 使用Closure Task & Queue Task: Operation ，一個程式區段，在GCD裡面就是Block或者Closure 有兩種操作模式： sync & async 差別在於是否創造 “新的Thread” 同步執行 同步操作會阻礙當前執行緒執行並等待，等當前執行緒完成才繼續執行 異步執行 異步操作，當前執行緒會繼續往下執行，不會阻礙執行緒 Queue Serial Queues(串行序列） 會進行FIFO（First in First out） Concurrent Queues(並行序列） 也是FIFO取出，但取出後會開啟多條執行緒直接取出又放到另外一個執行緒，由於取出動作很快，看起來所有任務同時執行，但是自根據系統資源控制並行數量，所以如果任務很多，不會同時讓任務一起執行。 Item sync async Serial Queues 執行緒，一個一個執行 其他執行緒，一個一個執行 Concurrent Queues 執行緒，一個一個執行 很多執行緒，同時執行 創造Queue Main Queue Create Queue Global Queue Main Queue mainqueue為自定義變數 /*OBJECTIVE-C*/ dispatch_queue_t mainqueue = dispatch_get_main_queue(); /*SWIFT*/ let mainqueue = dispatch_get_main_queue() Create Your Own Queue 自己可以創建串
