我如何code在UIActionSheet一个绿色按钮？ [英] How do I code a green button in UIActionSheet?

问题描述

我使用的是code：

  {
        randomstatus = 0;
        味精= [[NSString的页头] initWithFormat：@干得好，你要继续吗？];
        UIActionSheet * actionSheet = [[UIActionSheet的alloc] initWithTitle：消息委托：自我cancelButtonTitle：@否destructiveButtonTitle：@是otherButtonTitles：无];
        [actionSheet showInView：self.view];
        [actionSheet发布]
        [味精放]
    }
 

我不想改变code，但我需要的destructiveButton是绿色的，而不是红色。这是可能的，或者我需要使用不同的按钮？

解决方案

不幸的是没有任何自定义按钮UIActionSheet正式提供的方法。

但是，您可以访问UIActionSheet的子视图（这可能在未来的iPhone OS更新突破），或添加一个新的观点与一个按钮，覆盖原有的破坏性操作按钮（再次，这可能会破坏）。

虽然没有直接关系的改变按钮的颜色上的UIActionSheet，此previous问题：<一href=\"http://stackoverflow.com/questions/743636/iphone-disabling-uiactionsheet-buttons\">http://stackoverflow.com/questions/743636/iphone-disabling-uiactionsheet-buttons演示了几种方法，你可以添加自定义视图到UIActionSheet。

I am using the code:

  {
        randomstatus=0;
        msg=[[NSString alloc]initWithFormat:@"Good job, do you want to continue?"];
        UIActionSheet *actionSheet=[[UIActionSheet alloc]initWithTitle:msg delegate:self cancelButtonTitle:@"No" destructiveButtonTitle:@"Yes" otherButtonTitles:nil];
        [actionSheet showInView:self.view];
        [actionSheet release];
        [msg release];
    }   

I don't want to change the code, but I need the "destructiveButton" to be green instead of red. Is this possible, or do i need to use a different button?

解决方案

Unfortunately there aren't any officially provided methods for customizing UIActionSheet buttons.

However you can access the subviews of the UIActionSheet (which could break in a future iPhone OS update), or add a new view with a button that covers the original destructive action button (once again, this may break).

While not directly related to changing the color of a button on a UIActionSheet, this previous question: http://stackoverflow.com/questions/743636/iphone-disabling-uiactionsheet-buttons demonstrates a few ways you could add custom views to a UIActionSheet.
