objective-c - 如何设置不隐藏工具栏的部分 curl 模态？

Question

在 iPhone 上的 Google map 应用程序中，在预形成具有部分 curl 过渡的模态之后，按钮中的工具栏仍然可见。当我在 Storyboard中使用部分 curl 设置模态序列时，新的 View Controller 将工具栏从父 View 中隐藏起来。

如何像 Google map 应用一样设置部分 curl ？

试试这个代码。这会对你有所帮助。请不要犹豫尝试这个代码。

您需要导入一个 QuartzCore.framework。

locationMapView 是您的 MKMapView 而 curlView 是您的第二个 UIView

- (IBAction)curlButtonPressed:(id)sender {

    if (isCurlStarted == NO) {
        [UIView animateWithDuration:1.0 
                         animations:^{
                             CATransition *animation = [CATransition animation];
                             [animation setDelegate:self];
                             [animation setDuration:0.7];
                             [animation setTimingFunction:[CAMediaTimingFunction functionWithName:@"default"]];
                             animation.type = @"pageCurl";
                             animation.fillMode = kCAFillModeForwards;
                             animation.endProgress = 0.65;
                             [animation setRemovedOnCompletion:NO];
                             [locationMapView.layer addAnimation:animation forKey:@"pageCurlAnimation"];  
                             [locationMapView addSubview:curlView];
                             ;}  
         ];            
        isCurlStarted = YES;
    }else{
        [self curlDownPressed:curlDownButton];
    }

}

- (IBAction)curlDownPressed:(id)sender {
    [UIView animateWithDuration:1.0 
                     animations:^{
                         CATransition *animation = [CATransition animation];
                         [animation setDelegate:self];
                         [animation setDuration:0.7];
                         [animation setTimingFunction:[CAMediaTimingFunction functionWithName:@"default"]];
                         animation.type = @"pageUnCurl";
                         animation.fillMode = kCAFillModeForwards;
                         animation.startProgress = 0.35;
                         [animation setRemovedOnCompletion:NO];
                         [locationMapView.layer addAnimation:animation forKey:@"pageUnCurlAnimation"];  
                         [curlView removeFromSuperview];

                         ;}  
     ];
    isCurlStarted = NO;
}
