予定通り、ViewController間のデータのやりとりです。
ViewControllerから、SecondViewControllerにデータを渡します。
＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
ViewController.h
＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
ViewController.m
-(void)pushBtn1 {
// SecondViewControllerを生成
SecondViewController *vc = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil];
// SecondViewControllerのプロパティtitleStringに文字列を設定
vc.titleString = @"Push Button1";
// ナビゲーションによる画面遷移を実行
[self.navigationController pushViewController:vc animated:YES];
[vc release];
}
＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
SecondViewController.h
@property(nonatomic,retain) NSString * titleString;
＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
SecondViewController.m
@synthesize titleString = _titleString;
(中略)
- (void)dealloc
{
// メモリの片付け
[_titleString release];
[super dealloc];
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
// メモリの片付け
self.titleString = nil;
}
(中略)
-(void)setupParts {
// titleLblのテキストにViewControllerで設定したtitleStringを代入
titleLbl.text = self.titleString;
[self.view addSubview:titleLbl];
[titleLbl release];
（後略）
}
＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
これで、SecondViewControllerに "Push Button1" と表示されます。
とある講座で習ったので、おすそわけです。
