一行代码实现iOS项目启动页, 包括加载网络视频, 本地视频, 网络图片, 本地图片
github下载地址:https://github.com/ZHHalsey/AppStart(感觉有用可以点个star)
可以设置倒计时
使用方法很简单
导入写好的类ZHMoviePlayerController, 创建一个对象, 然后根据项目需求调用下面的两个对象方法(分加载视频跟加载图片,可以是网络的也可以是本地的)

如果加载的时候, 如果只加载网络图片不加载本地图片的话,本地图片参数传入为nil就可以,加载视频同理
这里展示的demo没加缓存, 我自己做的项目中加了缓存了,提供下思路在这里:
加缓存的话, 写入沙盒, 设置一个userdefault, 启动的时候先去沙盒找, 如果沙盒有的话就加载沙盒的, 沙盒没有的话就加载网络的, 然后把需要加载的启动页写入沙盒就行
demo展示放不了视频, 所以就放几张图片, 供大家参考
下面这个是视频启动页,可以点击按钮进入应用, 也可以设置几秒倒计时自动进入

下面这个是加载图片启动页, 这里是用的倒计时的加载

贴上源码：

/**
* @param imageURL 网上url图片
* @param localImageName 本地图片
* @param timeCount 倒计时时间
*/
- (void)setImageInIndexWithURL:(NSURL *)imageURL localImageName:(NSString *)localImageName timeCount:(int)timeCount;
@end

Appdelegate里的调用：

NSLog(@"后缀是--%@", [getUrlStr substringFromIndex:[getUrlStr length] - 4]);
ZHMoviePlayerController *ZHVC = [[ZHMoviePlayerController alloc]init];
if ([[getUrlStr substringFromIndex:[getUrlStr length] - 4] isEqualToString:@".mp4"] ) {
NSLog(@"加载的是视频");
// [ZHVC setMoviePlayerInIndexWithURL:[NSURL URLWithString:getUrlStr] localMovieName:nil]; // 加载网络url视频
[ZHVC setMoviePlayerInIndexWithURL:nil localMovieName:@"movie.mp4"]; // 加载本地视频
self.window.rootViewController = ZHVC;
}else if ([[getUrlStr substringFromIndex:[getUrlStr length] - 4] isEqualToString:@".png"]){
NSLog(@"加载的是图片");
// [ZHVC setImageInIndexWithURL:[NSURL URLWithString:getUrlStr] localImageName:nil timeCount:4];// 加载网络图片
[ZHVC setImageInIndexWithURL:nil localImageName:@"bj.png" timeCount:4]; // 加载本地图片
self.window.rootViewController = ZHVC;
}
return YES;
