ios - 信息灯按钮动画

Question

我无法显示infobutton导航到信息页面/视图。

我已经写了这段代码。

UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeInfoLight];
UIBarButtonItem *infoButtonItem = [[UIBarButtonItem alloc] initWithCustomView:infoButton];
toolBar.items = [NSArray arrayWithObjects:infoButtonItem, nil];

我有infolight按钮，但我现在不知道如何执行动画和导航操作方法以翻转到信息页面。

我还希望信息按钮留在中心，目前它在左角。

Answer 1

This will create ur info button in center.
UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeInfoLight];
    UIBarButtonItem *infoButtonItem = [[UIBarButtonItem alloc] initWithCustomView:infoButton];
    [infoButton addTarget:self action:@selector(goToRechercherView) forControlEvents:UIControlEventTouchUpInside];
    UIBarButtonItem *flexibleLeft = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
    toolbar.items = [NSArray arrayWithObjects:flexibleLeft,infoButtonItem,flexibleLeft, nil];


This is for swipe animation. add your view inside.
-(void)goToRechercherView{
    [UIView beginAnimations:@"flipview" context:nil];
    [UIView setAnimationDuration:2];
    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
    [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft
                           forView:self.view cache:YES];
    [UIView commitAnimations];
}

有两种方法可以做到这一点...

第一个是……

newView setFrame:CGRectMake( 0.0f, 480.0f, 320.0f, 480.0f)]; //notice this is OFF screen!
[UIView beginAnimations:@"animateView" context:nil];
[UIView setAnimationDuration:0.4];
[newView setFrame:CGRectMake( 0.0f, 0.0f, 320.0f, 480.0f)]; //notice this is ON screen!
[UIView commitAnimations];

第二种选择是使用内置动画作为翻转和卷曲：

    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:1.0];
    [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight
                               forView:newView
                                cache:YES];

    [self.navigationController.view addSubview:settingsView.view];
    [UIView commitAnimations];
