一行代碼實現(xiàn)iOS項目啟動頁, 包括加載網(wǎng)絡視頻, 本地視頻, 網(wǎng)絡圖片, 本地圖片

可以設置倒計時

使用方法很簡單

導入寫好的類ZHMoviePlayerController, 創(chuàng)建一個對象, 然后根據(jù)項目需求調(diào)用下面的兩個對象方法(分加載視頻跟加載圖片,可以是網(wǎng)絡的也可以是本地的)

如果加載的時候, 如果只加載網(wǎng)絡圖片不加載本地圖片的話,本地圖片參數(shù)傳入為nil就可以,加載視頻同理

這里展示的demo沒加緩存, 我自己做的項目中加了緩存了,提供下思路在這里:

加緩存的話, 寫入沙盒, 設置一個userdefault, 啟動的時候先去沙盒找, 如果沙盒有的話就加載沙盒的, 沙盒沒有的話就加載網(wǎng)絡的, 然后把需要加載的啟動頁寫入沙盒就行

demo展示放不了視頻, 所以就放幾張圖片, 供大家參考

下面這個是視頻啟動頁,可以點擊按鈕進入應用, 也可以設置幾秒倒計時自動進入

下面這個是加載圖片啟動頁, 這里是用的倒計時的加載

貼上源碼：

/**
 *  @param movieURL 網(wǎng)上url視頻
 *  @param localMovieName 本地視頻
 */
- (void)setMoviePlayerInIndexWithURL:(NSURL *)movieURL localMovieName:(NSString *)localMovieName;

/**
 *  @param imageURL 網(wǎng)上url圖片
 *  @param localImageName 本地圖片
 *  @param timeCount 倒計時時間
 */

- (void)setImageInIndexWithURL:(NSURL *)imageURL localImageName:(NSString *)localImageName timeCount:(int)timeCount;

Appdelegate里的調(diào)用：

    // 這是圖片還有視頻的url鏈接

//    NSString *getUrlStr = @"http://fimg.yucuizhubao.com/img/start.png"; // 網(wǎng)絡圖片
    
    NSLog(@"后綴是--%@", [getUrlStr substringFromIndex:[getUrlStr length] - 4]);
    ZHMoviePlayerController *ZHVC = [[ZHMoviePlayerController alloc]init];
    
    if ([[getUrlStr substringFromIndex:[getUrlStr length] - 4] isEqualToString:@".mp4"] ) {
        NSLog(@"加載的是視頻");
//        [ZHVC setMoviePlayerInIndexWithURL:[NSURL URLWithString:getUrlStr] localMovieName:nil]; // 加載網(wǎng)絡url視頻
        [ZHVC setMoviePlayerInIndexWithURL:nil localMovieName:@"movie.mp4"]; // 加載本地視頻
        self.window.rootViewController = ZHVC;
        
    }else if ([[getUrlStr substringFromIndex:[getUrlStr length] - 4] isEqualToString:@".png"]){
        NSLog(@"加載的是圖片");
//        [ZHVC setImageInIndexWithURL:[NSURL URLWithString:getUrlStr] localImageName:nil timeCount:4];// 加載網(wǎng)絡圖片
        [ZHVC setImageInIndexWithURL:nil localImageName:@"bj.png" timeCount:4]; // 加載本地圖片
        self.window.rootViewController = ZHVC;
    }
    return YES;
