一鍵集成APP引導頁,包括圖片啟動圖以及利用視頻做引導頁（利用視頻做引導頁采取 布袋的世界 的建議），并都擁有不同狀態(tài)下的引導頁樣式,省掉冗余的代碼,集成性高,使用方便。

2. SHStartPageView使用
簡單使用：
// 根據(jù)圖片數(shù)組創(chuàng)建啟動圖
NSArray *imageArray = @[@"1.jpg",@"2.jpg",@"3.jpg",@"4.jpg"];
SHStartPageView *shStartPageView = [[SHStartPageView alloc] initWithImageArray:imageArray enterButtonIsHidden:NO];
[self.window.rootViewController.view addSubview: shStartPageView];
// 根據(jù)視頻名稱和類型創(chuàng)建啟動圖
SHStartPageView *shStartPageView = [[SHStartPageView alloc] initWithVideoName:@"1" videoType:@"mp4" enterButtonIsHidden:NO];
[self.window.rootViewController.view addSubview:shStartPageView];
常用用法：
// 判斷第一次進入
if (![[NSUserDefaults standardUserDefaults] boolForKey:@"firstLaunch"]) {
NSLog(@"第一次進入");
[[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"firstLaunch"];
// 根據(jù)圖片數(shù)組創(chuàng)建啟動圖
NSArray *imageArray = @[@"1.jpg",@"2.jpg",@"3.jpg",@"4.jpg"];
SHStartPageView *shStartPageView = [[SHStartPageView alloc] initWithFrame:self.window.frame ImageArray:imageArray enterButtonIsHidden:NO];
// 根據(jù)視頻名稱和類型創(chuàng)建啟動圖
SHStartPageView *shStartPageView = [[SHStartPageView alloc] initWithVideoName:@"1" videoType:@"mp4" enterButtonIsHidden:NO];
[self.window.rootViewController.view addSubview:shStartPageView];
}
