嗯？

谷歌没有返回这个错误是什么......我所做的就是将一个movieplayercontroller添加到一个反面iphone应用程序中。

将编译器转为 clang(llvc) 后

我得到了这个内部编译器错误：分段错误

-(IBAction)clickedOpenMovie:(void)sender
{
    NSString *myString = [NSString stringWithFormat:@"http://localhost:1935/mystream/mystream.sdp"];

    NSURL *myURL = [NSURL URLWithString:myString];

   [self playMovieAtURL:myURL];

}

-(IBAction)clickedOpenMovie:(void)sender

那是错误的。void表示没有类型，并且您不能将没有类型的参数传递给函数。这可能就是让你从 cc1obj 得到错误的原因。

动作方法的正确签名是：

-(IBAction)clickedOpenMovie:(id)sender

id是任何 Objective-C 对象的类型。

NSString *myString = [NSString stringWithFormat:@"http://localhost:1935/mystream/mystream.sdp"];

这既是错误的，因为那不是格式字符串，也是没有意义的，因为您已经在那里有了完成的字符串。剪下消息并将字符串直接分配给变量：

NSString *myString = @"http://localhost:1935/mystream/mystream.sdp";

只有stringWithFormat:当你有一个格式字符串和一些你想要拼接到其中的值时，你才应该使用它。

对于其他人得到完全没有帮助的错误消息：“类型'（{anonymous}）'没有已知的大小”，这是因为你搞砸了你的方法原型之一。因此，在上述情况下，错误是由废话 (void) 参数引起的。所有其他错误都是与第一个错误无关的链接错误。因此，请检查您是否没有将 (id) 类型添加到其他内容中。

所以问题是我没有将框架添加到我的 xcode 项目中，因此链接库不存在。
