Question

我有一个带图像的应用程序，一旦用户按下图像，就会播放声音片段。一旦我到达最后一张没有声音剪辑的图像（25），如果我按下该应用程序自动关闭，我该如何防止这种情况。

例如，我需要播放C01.mp3一旦用户点击01.Png（注意我的所有图像也保存在图像阵列中）基本上我有25.png这只是我网站的广告所以它不会有一个声音剪辑，但一旦我点击该图像，应用程序将自动关闭。需要帮助来解决这个问题。

替换

for(NSString *soundName in soundNames)
{

与

for(int i = 0 ; i < soundNames.count-1 ; i++)
{
   NSString *soundName = [soundNames objectAtIndex:i];
   //rest of the code same

这将运行循环，直到24个索引数组的23个索引...

当我到达ios5中的最后一个声音片段时，应用程序挂起
