ios - 将按钮导出添加到 IBoutletCollection Xcode

Question

我想向 IBOutletCollection 添加 15 个 UIButton 并分别更改每个 UIButton 的标签。我可以为每个按钮分配一个标签，然后以某种方式更改与按钮标签相关的按钮标签吗？或者它们是否需要成为我更改单个按钮标签的单独导出？

Answer 1

在按钮单击方法中编写此代码。设置标签并检查其条件并设置 特定标签的标题

-(IBAction)btnClick:(id)sender{

UIButton * btn = (UIButton *)sender;
int btag = btn.tag;

if(btag == 1)
    [btn setTitle:@"Your Title " forState:UIControlStateNormal];
else if (btag == 2)
     [btn setTitle:@"Your Title " forState:UIControlStateNormal];
}
