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 @synthesize isanimating = _isanimating; @synthesize pageScroll = _pageScroll; @synthesize enter_button; @synthesize pagecount; static SplashViewController *instance = nil; - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self){ self.view.frame = CGRectMake(0, 0, Main_Screen_Width, Main_Screen_Height); self.view.backgroundColor = [UIColor whiteColor]; self.pagecount=0; //[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent]; } return self; } //添加切换页 -(void)addpage:(NSString*)imagename{ UIImageView *view; view = [[UIImageView alloc] initWithFrame:CGRectMake((self.view.frame.size.width * pagecount), 0, self.view.frame.size.width, Main_Screen_Height)]; UIImage *img=[UIImage imageNamed:imagename]; view.image = img; view.userInteractionEnabled = YES; // UIEdgeInsets insets = UIEdgeInsetsMake(10, 10, 400, 10); // img=[img resizableImageWithCapInsets:insets];

UIView *uiview=[self.pageScroll.subviews objectAtIndex:self.pageScroll.subviews.count-1]; if(self.enter_button!=nil){ [self.enter_button addTarget:self action:@selector(pressEnterButton:) forControlEvents:UIControlEventTouchUpInside]; [uiview addSubview:self.enter_button]; } } //加载视图 - (void)viewDidLoad { [super viewDidLoad]; CGRect frame=[UIScreen mainScreen].bounds; if( ([[[UIDevice currentDevice] systemVersion] doubleValue]>=7.0)) { // [self.navigationBar setBarTintColor:[UIColor redColor]];

} } @end
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]; } }
