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：

#import "ViewController.h"

@interface ZHMoviePlayerController : ViewController

/**
 *  @param movieURL 网上url视频
 *  @param localMovieName 本地视频
 */
- (void)setMoviePlayerInIndexWithURL:(NSURL *)movieURL localMovieName:(NSString *)localMovieName;

/**
 *  @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

#define SCREEN_HEIGHT [UIScreen mainScreen].bounds.size.height
#define SCREEN_WIDTH [UIScreen mainScreen].bounds.size.width


#import "ZHMoviePlayerController.h"
#import <AVFoundation/AVFoundation.h>
#import <AVKit/AVKit.h>

@interface ZHMoviePlayerController ()

    [btn setTitle:@"进入应用" forState:UIControlStateNormal];

}

    ViewController *vc = [[ViewController alloc]init];
    self.view.window.rootViewController = vc;
    [self.AVPlayer.player pause];
}
@end

Appdelegate里的调用：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    
    // 这是图片还有视频的url链接
    NSString *getUrlStr = @"http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"; // 网络视频
//    NSString *getUrlStr = @"http://fimg.yucuizhubao.com/img/start.png"; // 网络图片
    
    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;
}
