storyBoard 運用,兩個ViewController之間的資料傳送

目標:
1.storyBoard的介紹與使用
2.在不同viewController間傳送資料 使用storyBoard,

首先要確定是否有存在多個,如果有多個storyBoard,則可以在plist 檔案中的[Main storyboard file base name];則是指出哪一個storyBoard才是我們所使用的,在點選storyBoard,畫面會出現step 1 的按鈕,此按鈕可以用來開關 storyBoard下所有viewController的清單.在清單中可以拖曳來決定ViewController的開啓流程.感覺確實比用nib 的方式要直覺得
許多.




此storyBoard共包含了三個viewController,本範例中共會使用到兩個,分別是root的UIStoryboardDemoViewController,以及按下go Value0的所出現的UIStoryboardSubViewController

#import "UIStoryboardDemoViewController.h"

@interface UIStoryboardDemoViewController ()

@end

@implementation UIStoryboardDemoViewController

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

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
//過場傳送端
-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
	//將資料送到destinationViewController
	id secondCon =segue.destinationViewController;
	[secondCon setValue:@"From Hello" forKey:@"dataString"];
}
