創建專案時選擇Master-Detail Application，
並改寫MaterViewController.m檔，
程式碼如下:
//
// MasterViewController.m
// tableView
//

//

#import "MasterViewController.h"
#import "DetailViewController.h"

@interface MasterViewController ()

@property NSMutableArray *objects;
@end

@implementation MasterViewController

- (void)awakeFromNib {
[super awakeFromNib];
}

- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
self.navigationItem.leftBarButtonItem = self.editButtonItem;

UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(insertNewObject:)];
self.navigationItem.rightBarButtonItem = addButton;

dataArray = [[NSMutableArray alloc]initWithObjects: //陣列儲存欲顯示之資料
@{@"Title": @"banana", @"ImageFileName": @"banana.png"},
@{@"Title": @"tomato", @"ImageFileName": @"tomato.png"},
@{@"Title": @"guava", @"ImageFileName": @"guava.png"}, nil];
}

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

- (void)insertNewObject:(id)sender {
if (!self.objects) {
self.objects = [[NSMutableArray alloc] init];
}
[self.objects insertObject:[NSDate date] atIndex:0];
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
[self.tableView insertRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
}

#pragma mark - Segues

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([[segue identifier] isEqualToString:@"showDetail"]) {
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
NSDate *object = self.objects[indexPath.row];
[[segue destinationViewController] setDetailItem:object];
}
}

#pragma mark - Table View

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1; //只顯示一個section
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {

return [dataArray count]; //回傳列數
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell" forIndexPath:indexPath];

NSDate *object = self.objects[indexPath.row]; //呈現物件資料
cell.textLabel.text = [[dataArray objectAtIndex:indexPath.row]
objectForKey:@"Title"];
return cell;
}

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
// Return NO if you do not want the specified item to be editable.
return YES;
}

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete) {
[self.objects removeObjectAtIndex:indexPath.row];
[tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade];
} else if (editingStyle == UITableViewCellEditingStyleInsert) {
// Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view.
}
}

UIScrollView可幫助我們在手機顯示的小畫面中瀏覽大圖，
將大圖複製進xcode後，在套入以下程式碼即可執行。
viewController.h
#import <UIKit/UIKit.h>

@interface ViewController : UIViewController<UIScrollViewDelegate>
{
UIImageView *imageView;
UILabel *scaleRatioLabel;
}

@end

此方法是設定一個NSArray儲存動畫所需圖片，
再取出array的index值，
在採用NSTimer或迴圈操作index值來播放動畫，
取出NSArray之index可參考以下語法。

UIImageView實現縮放特效動畫
 
#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
NSArray *animationImages = @[
[UIImage imageNamed:@"1.jpg"],
[UIImage imageNamed:@"2.jpg"],
[UIImage imageNamed:@"3.jpg"],
[UIImage imageNamed:@"4.jpg"]
];

UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(10, 10, 300, 300)];
imageView.animationImages = animationImages ;
imageView.animationRepeatCount = 0;
imageView.animationDuration= 12.0;
[imageView startAnimating];
[self.view addSubview:imageView];

// 當圖片改變時呼叫執行動畫的 method => scaleView:
[[NSTimer scheduledTimerWithTimeInterval:12.0/animationImages.count
target:self
selector:@selector(scaleView:)
userInfo:@{
@"view": imageView
}
repeats:YES] fire];
}

- (void)scaleView:(NSTimer *)timer {
UIImageView *view = [timer.userInfo objectForKey:@"view"];
view.frame = CGRectMake(150, 150, 20, 20);
CGPoint center = view.center;
[UIView animateWithDuration: 1.0f
animations:^{
view.frame = CGRectMake(10, 10, 300, 300);
view.center = center;
}];

}
@end

此範例先將動畫要用之圖片複製近xcode中,
接著使用一個array並存放圖片,
之後創建一個imageView物件顯示動畫窗格,
再透過[imageView startAnimating]此方法播放動畫, 程式碼如下
