感谢您的帮助。

Answer 1

使用视频标记上的“poster”属性。

例如：

switch (RandomNumber) {

case 1:

    Question.text = "What greeting would you use in the morning"

   //Logic goes here

    NSMutableArray *arrAnswers=[[NSMutableArray alloc]  
     initWithObjects:@"Hello",@"Goodbye",@"Good Morning",@"See you soon",@"Ni Hao",@"CTA",nil];
     NSMutableArray *buttons = [NSMutableArray arrayWithObjects: Answer1,Answer2,Answer3,Answer4,Answer5,Answer6, nil];
     for (UIButton *btn in buttons) {
           int randomIndex= arc4random() % [arrAnswers count];
           NSString* btnTitle = [arrAnswers objectAtIndex:randomIndex];
           [btn setTitle:btnTitle forState:UIControlStateNormal]; 
           [arrAnswers removeObjectAtIndex:randomIndex];                        
    }
  //End of Logic 
      CorrectAnswer = "1"
            break

如果您没有为海报属性指定值，则播放器将使用源视频的第一帧作为海报。
