如何实现pagecontrol的视图

Question

我即将创建一个App.

它应该有3个主页.所以我想到了用PageControl实现这个目标.

我创建了3个视图,现在我被困在这个PageControl的实现上.

有没有人可以看一下好的教程或示例代码(它也可以是德语)？

谢谢,迈克尔

这是一个如何使用它的简单想法.

PageController.h:

#import <UIKit/UIKit.h>

@interface PageController : UIViewController {
    NSArray * views;
    UIPageControl *pageControl;
}

@property (nonatomic, retain) IBOutlet UIPageControl * pageControl;

- (IBAction) changePage:(id)sender;
- (void) animateToView:(UIView *)newView;

@end

PageController.m:

#import "PageController.h"

@implementation PageController

- (void)viewDidLoad {
    [super viewDidLoad];
    pageControl.numberOfPages = [views count];
    pageControl.currentPage = 0;

    // Either wire this up in Interface Builder or do it here.
    [pageControl addTarget:self action:@selector(changePage:) forControlEvents:UIControlEventValueChanged];
}

- (IBAction) changePage:(id)sender {
    UIView * newView = [views objectAtIndex:[pageControl currentPage]];
    [self animateToView:newView];
}

- (void) animateToView:(UIView *)newView {
     // You'd have to implement this yourself
}

@end
