收集整理的這篇文章主要介紹了
的界面跳转
小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.
在界面的跳轉有兩種方法，一種方法是先刪除原來的界面，然后在插入新的界面：如下代碼
if?(self.rootViewController.view.superview ==?nil) {
[singleDollController.view?removeFromSuperview];
[self.view?insertSubview:rootViewController.view?atIndex:0];
}
else?{
[rootViewController.view?removeFromSuperview];
[self.view?insertSubview:singleDollController.view?atIndex:0];
}
使用這種方式無法實現(xiàn)界面跳轉時的動畫效果。
另一中方式為將跳轉的界面的Controller放入到UINavigationController中，使用push或pop實現(xiàn)跳轉：使用這種方式可用實現(xiàn)動畫效果
navController?= [[UINavigationController?alloc]init];
[navController?setNavigationBarHidden:YES];
[window?addSubview:navController.view];
rootView?= [[RootViewController?alloc]?initWithNibName:@"RootViewController"?bundle:nil];
[navController?pushViewController:rootView?animated:NO];
?
///
self.singleDollView?= view;
[UIView?beginAnimations:nil?context:NULL];
[UIView?setAnimationDuration:0.5];
[UIView?setAnimationTransition:UIViewAnimationTransitionFlipFromLeft?forView:self.navController.view?cache:NO];
[self.navController?pushViewController:self.singleDollView?animated:NO];
[UIView?commitAnimations];

1 創(chuàng)建一個基于Navigation－based Application的iphone工程，為什么要創(chuàng)建基于Navigation－based Application的工程呢，因為這樣系統(tǒng)就會自動將Navigation視圖加到我們的窗口視圖中，這樣我們就不用自己手動去加，并且可以用
[ self . navigationController pushViewController :otherview animated : YES ]去跳轉頁面。當設置每個頁面的標題后會在頁面左上角自動生成后退導航按鈕，多方便呀,當然需要在建立后將xib文件里面的tableview去掉加入view。
2 新建一個頁面，我這里是OtherView，讓系統(tǒng)自動生成.h,.xib文件。
3 第一個頁面上面添加一個文本筐和一個按鈕，點擊按鈕后調轉到第二個頁面并將文本筐里面的數(shù)據(jù)傳入第二個頁面。第二個頁面用一個label來顯示傳過來的數(shù)據(jù)。

?首先是自動生成的協(xié)議里面的代碼，注意看navigationController ：
