IPhone之动画左右旋转

[UIView setAnimationTransition: UIViewAnimationTransitionFlipFromLeft forView:whiteBackdrop cache:YES];

这个属性可以设置动化的旋转方向

?

代码如下：

?

- (void) animationFinished: (id) sender

{

self.navigationItem.rightBarButtonItem =[[[UIBarButtonItem alloc] initWithTitle:@"11" style:UIBarButtonItemStylePlain target:self action:@selector(flip:)] autorelease];

}

?

- (void) flip: (id) sender

{

// 隐藏右侧按钮

self.navigationItem.rightBarButtonItem = nil;

CGContextRef context = UIGraphicsGetCurrentContext();

[UIView beginAnimations:nil context:context];

[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];

[UIView setAnimationDuration:1.0];

//获取移动的view

UIView *whiteBackdrop = [self.view viewWithTag:100];

// 选择是左移还是右移

if ([(UISegmentedControl *)self.navigationItem.titleView selectedSegmentIndex])

[UIView setAnimationTransition: UIViewAnimationTransitionFlipFromLeft forView:whiteBackdrop cache:YES];

else

[UIView setAnimationTransition: UIViewAnimationTransitionFlipFromRight forView:whiteBackdrop cache:YES];

NSInteger purple = [[whiteBackdrop subviews] indexOfObject:[whiteBackdrop viewWithTag:999]];

NSInteger maroon = [[whiteBackdrop subviews] indexOfObject:[whiteBackdrop viewWithTag:998]];

[whiteBackdrop exchangeSubviewAtIndex:purple withSubviewAtIndex:maroon];

[UIView setAnimationDelegate:self];

[UIView setAnimationDidStopSelector:@selector(animationFinished:)];

[UIView commitAnimations];

}

- (void)loadView

{

self.navigationController.navigationBar.tintColor = [UIColor colorWithRed:0.20392f green:0.19607f blue:0.61176f alpha:1.0f];

self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:@"11" style:UIBarButtonItemStylePlain target:self action:@selector(flip:)] autorelease]; //BARBUTTON(@"Flip",);

?

?

// 设置分段控件 标题

UISegmentedControl *seg = [[[UISegmentedControl alloc] initWithItems:[@"左转 右转" componentsSeparatedByString:@" "]] autorelease];

seg.selectedSegmentIndex = 0;

seg.segmentedControlStyle = UISegmentedControlStyleBar;

self.navigationItem.titleView = seg;

//设置转向的view

UIView *view100=[[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320, 480)];

view100.tag=100;

view100.backgroundColor=[UIColor blueColor];

self.view=view100;
}
