我想模仿[NSArray arrayWithObjects：]的功能,这允许我以这种方式输入争论：[MyClass doSomethingWithObjects：@“str1”,@“str2”,nil].假设这是可能的,我该如何声明？
解决方法

//interface:
- (void)foo:(NSString *)firstString,... NS_REQUIRES_NIL_TERMINATION;
//implementation:
- (void)foo:(NSString *)firstArg,...
{
va_list args;
va_start(args,firstArg);
for (NSString *arg = firstArg; arg != nil; arg = va_arg(args,NSString*))
{
[self bar:arg];
}
va_end(args);
}
