帶有靜態內容的UIPageViewController

Question

我想在UIPageViewController上放置一些靜態內容（按鈕，視圖等）。但我不知道如何。

任何想法？

Answer 1

只需創建一個容器uiviewcontroller，將有例如一個靜態按鈕和一個空的uiview。創建它們作爲iboutlets和通常屬性UIPageViewController稱爲pvc。然後你可以在代碼中創建一個pvc，並通過addSubview:將它添加到uiview插座。

這是從我上個週末做的一個項目複製的一些代碼。在UIPageViewController中有Skidata，並將一個雪花的UIImage作爲覆蓋。我只複製了代碼的相關部分。希望這將幫助你：

SkiViewController.m

@interface SkiViewController() <UIPageViewControllerDataSource> 

@property (strong, nonatomic) UIPageViewController *pageController; 
@property (strong, nonatomic) SkiDataArray* skiDataArray; 

@property (weak, nonatomic) IBOutlet UIImageView *imageView; 
@property (weak, nonatomic) IBOutlet UIView *pageDataView; 

@end 

@implementation SkiViewController 

- (SkiSubViewController *)viewControllerAtIndex:(NSUInteger)index 
{ 
    SkiSubViewController *childViewController = [[SkiSubViewController alloc] initWithNibName:@"SkiSubViewController" bundle:nil]; 
    childViewController.indexNumber = index; 

    if(self.skiDataArray) 
    { 
     childViewController.skiData = self.skiDataArray[index]; 
    } 

    return childViewController; 
}

    self.pageController.dataSource = self; 

    [self addPageControllerViewControllers];

    [self.pageDataView addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|[subview]|" options:0 metrics: 0 views:views]]; 
    [self.pageDataView addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|[subview]|" options:0 metrics: 0 views:views]]; 
    [self.pageDataView updateConstraintsIfNeeded]; 
}
