方法的实现
- (instancetype)initWithButtonTitles:(nullable NSString*)buttonTitles,...NS_REQUIRES_NIL_TERMINATION
{
self = [super init];
if (self) {
NSMutableArray* btnTitles = [NSMutableArray new];
if (buttonTitles) {
[btnTitles addObject:buttonTitles];
va_list arglist;
va_start(arglist,buttonTitles);
NSString *arg;
while ((arg = va_arg(arglist, NSString *)))
{
NSLog(@"%@", arg);
[btnTitles addObject:arg];
}
va_end(arglist);
}
}
return self;
}
