iphone SDK로 사파리 탭보기 전환 기능을 복제하십시오.

Question

모바일 사파리의 탭 기능에있는보기 전환 기능을 복제하고 싶습니다. 그러나 뷰 스크린 샷을 포함하는 scrollview를 구현했습니다. 뷰를 선택하면 줌 애니메이션과 제목 및 툴바가 어떻게 나타나며 그 반대의 경우도 복제됩니까?

- (void)clickHandler{ 

// create an image that looks exactly like 
// the preview image in your scroll view (can leave off the toolbar/statusbar if you like) 
UIImage *img = [UIImage imageNamed:@"something.png"]; 

// create an imageview to hold the image 
UIImageView *iv = [[UIImageView alloc] initWithImage:img]; 

// ensure that the frame is set so that it's directly over the image in your scrollview 
iv.frame = CGRectMake(60, 150, 200, 200); 

// push the image into the superview over top this controller's view 
[[self.view superview] insertSubview:iv aboveSubview:self.view]; 

// refresh superview NOW 
[[self.view superview] performSelectorOnMainThread:@selector(setNeedsDisplay) withObject:nil waitUntilDone:YES]; 

//----------- 
//animate the image to bring it from it's "scrollview size" to the size it will be after the transition. 

[UIImageView beginAnimations:nil context:nil]; 
[UIImageView setAnimationDuration:0.3]; 

iv.frame = CGRectMake(0, 65, 320, 371); 

[UIImageView commitAnimations]; 

//----------- 

// transition to the new view using the CrossDissolve transition (or just don't animate it.) 
NewViewController *controller = [[NewViewController alloc] initWithNibName:@"NewView" bundle:nil]; 
controller.modalTransitionStyle = UIModalTransitionStyleCrossDissolve; 
[self presentModalViewController:controller animated:YES]; 
[controller release]; 

// set the animated imageview to remove itself after a delay 
// (after the new view is transitioned into place below it.) 
[iv performSelector:@selector(removeFromSuperview) withObject:nil afterDelay:0.3]; 

// be sure to release where needed and all that, I may have cut too much from the code for this snippet. 
// this may not be the best example, but it does work. 
// please post any improvements back so that we can all benefit
