2. 

[AVPlayer play];  模拟器播放出错

这两天研究视频播放，集成RTMP视频出现的异常，刚好看到一篇博客，楼主使用［AVAudioPlayer Play］时出现了异常。。。记录下来

由于xcode中设置了当所有异常出现时的断点，，解决办法是将all改为Objective-C

3.获取手机安装的应用的所有信息  包括name，bundleIdentitifer

    Class c =NSClassFromString(@"LSApplicationWorkspace");
    id s = [(id)c performSelector:NSSelectorFromString(@"defaultWorkspace")];
    NSArray *array = [s performSelector:NSSelectorFromString(@"allInstalledApplications")];
    for (id item in array)
    {
        NSLog(@"%@",[item performSelector:NSSelectorFromString(@"applicationIdentifier")]);
        NSLog(@"%@",[item performSelector:NSSelectorFromString(@"bundleIdentifier")]);
        //        NSLog(@"%@",[item performSelector:NSSelectorFromString(@"bundleVersion")]);
        //        NSLog(@"%@",[item performSelector:NSSelectorFromString(@"shortVersionString")]);
        NSLog(@"%@",[item performSelector:NSSelectorFromString(@"itemName")]);
        
    }
