肯定必须有办法:)这实际上取决于你如何创建和存储你的按钮。您可以将它们存储在数组中并循环处理它们:

for (UIButton* button in buttonsArray)
   button.hidden = NO;

您还可以在创建UIButton时为其分配唯一的tag属性(此属性在UIView中定义,并在其所有子类中可用)。这样,您不需要单独存储按钮,也可以将它们隐藏在循环中:

for (int tag = min_tag_value; tag < max_tag_value;++tag)
    // Assume that self.view is a view that contains your buttons
    [self.view viewWithTag:tag].hidden = NO;

您也可以使用Key Value Coding

我认为会是这样的:

for (int i = 1; i <=35; i++)
{
    [self setValue:NO forKey:@"[NSString stringWithFormat:@"button%d", i]];
}
