这让我发疯，认为这是一个简单的，但任何帮助都会很棒，尝试下载远程 PLIST 并使用它来驱动应用程序内的配置....

得到

IMProductsDataSource.m:57:11: 错误：预期标识符或'('
NSURL = *remoteURL = [NSURL URLWithString:@"IOS/"];
^
IMProductsDataSource.m:58:94: 错误：使用未声明的标识符'remoteURL'
NSMutableDictionary *remoteDictionary = [NSMutableDictionary dictionaryWithContentsOfURL:remoteURL];
^
2 个错误生成。

任何帮助都会很棒...

您的变量声明不正确：

NSURL = *remoteURL = [NSURL URLWithString:@"http://URL/IOS/"];

应该：

NSURL *remoteURL = [NSURL URLWithString:@"http://URL/IOS/"];

请注意，您有一个额外的等号，之后NSURL会导致语法错误。

这是一个简单的语法错误。您的代码中的这一行不是有效的 Objective-C：

NSURL = *remoteURL = [NSURL URLWithString:@"http://URL/IOS/"];

看起来你只是不想要第一个=。
