ios - 信息灯按钮动画

Question

我在显示 infobutton 以导航到信息页面/ View 时遇到问题。

这段代码是我写的。

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使用动画和导航操作方法来翻转到信息页面。

我也希望 infobutton 保持在中间，目前它在左下角。

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];
}
