第一次加载应用时的滑动启动页

首先新建一个类：SplashViewController

还是直接贴代码： .h文件

#import <UIKit/UIKit.h>
#import "UIButton+Bootstrap.h"

@interface SplashViewController : UIViewController{
    

}
//页数量
@property (nonatomic,assign)  NSInteger pagecount;
//是否动画
@property (nonatomic, assign) BOOL isanimating;
//滑动页视图
@property (nonatomic, strong) UIScrollView  *pageScroll;
//是否显示按钮
@property (nonatomic,retain)  UIButton* enter_button;

//添加切换页
-(void)addpage:(NSString*)imagename;

//添加进入按钮
-(void)addenterbutton:(NSString*)title imgNor:(NSString*)imgnor imgPress:(NSString*)imgpress;


//显示
- (void)show;

//隐藏
- (void)hide;

//单例
+(SplashViewController*) sharedSplashViewController;

//获取屏幕大小
-(CGRect) getscreenFrame;

@end

.m文件:

#import "SplashViewController.h"
//#import "RailwayClientApplication.h"

@interface SplashViewController ()

@end

@implementation SplashViewController

在要引用启动页的类中插入一下代码：

//显示快显视图
-(void)showSplashViewController{
    //第一次启动程序的过场动画
    if ( [[NSUserDefaults standardUserDefaults] boolForKey:@"isnofirst"] == NO) {
        //添加切换页面
        [[SplashViewController sharedSplashViewController]addpage:@"ydy_1.jpg"];
        [[SplashViewController sharedSplashViewController]addpage:@"ydy_2.jpg"];
        [[SplashViewController sharedSplashViewController]addpage:@"ydy_3.jpg"];
        [[SplashViewController sharedSplashViewController]addpage:@"ydy_4.jpg"];
        //添加进入按钮
        [[SplashViewController sharedSplashViewController]addenterbutton:@"开始进入" imgNor:@"btn_nor" imgPress:@"btn_press"];
        [[SplashViewController sharedSplashViewController] show];
    }
}
