UIPageViewController实现的左右滑动界面
本文实例为大家分享了UIPageViewController实现左右滑动界面展示的具体代码,供大家参考,具体内容如下
.h
#import <UIKit/UIKit.h>
@interface ViewController : UIViewController
@end
.m
#import "ViewController.h"
#import "SubPage1ViewController.h"
#import "SubPage2ViewController.h"

@property NSArray *contentViewControllers; //ViewControllers
@property (nonatomic, span) UIPageViewController *pageViewController;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
[self pageViewController];
}

}
