objective-c - no rule to process file 是什么意思？

Question

Warning: no rule to process file '$(PROJECT_DIR)/YIFullScreenScrollDemo/../../Classes/UIViewController+YIFullScreenScroll.m' of type file for architecture i386

我正在尝试实现 YIFullScreenScrollDemo

在不断失败后，我只是将整个 .h 和 .m 文件复制到主项目中。其实我保留引用。

现在以这段代码为例，通过编译检查:

self.fullScreenScroll = [[YIFullScreenScroll alloc] initWithViewController:self scrollView:self.tableView];

然而，在运行时，我得到:

YIFullScreenScrollDemo[82387:c07] -[FirstViewController setFullScreenScroll:]: unrecognized selector sent to instance 0x7577e80

我还收到了这 4 个警告:

Warning: no rule to process file '$(PROJECT_DIR)/YIFullScreenScrollDemo/../../Classes/UIViewController+YIFullScreenScroll.m' of type file for architecture i386
Warning: no rule to process file '$(PROJECT_DIR)/YIFullScreenScrollDemo/../../Classes/YIFullScreenScroll.m' of type file for architecture i386
Warning: no rule to process file '$(PROJECT_DIR)/YIFullScreenScrollDemo/../Pods/JRSwizzle/JRSwizzle.m' of type file for architecture i386
Warning: no rule to process file '$(PROJECT_DIR)/YIFullScreenScrollDemo/../../Classes/UIView+YIFullScreenScroll.m' of type file for architecture i386

问题是什么？

注意:与另一个不重复compilation warning: no rule to process file for architecture i386

这个用于 .m 文件。另一个问题是.h文件

当然，我们确实需要包含 .m 文件，对吗？

Answer 1

如果您没有人们提到的 .h 问题，mojtaba 所说的适用于 .m 文件 (+1)。

单击“产品”菜单，按住 ALT 键启用“清理构建文件夹...”选项，然后重新编译。错误消失了。
