UIActionSheet按钮的颜色 [英] UIActionSheet button's color

问题描述

如何更改UIActionSheet按钮的颜色？

How can I change the color of UIActionSheet button's color?

推荐答案

iOS 8（UIAlertController）

如果你使用的是UIAlertController，超级简单。只需更改UIAlertController视图上的色调。

It's super simple to do if you're using a UIAlertController. Simply change the tint color on the view of the UIAlertController.

[alertController.view setTintColor:[UIColor red];

iOS 7（UIActionSheet）

我通过这个简单的方法成功地改变了文本的颜色。

I successfully change the text color by using this simple method.

- (void) changeTextColorForUIActionSheet:(UIActionSheet*)actionSheet {
    UIColor *tintColor = [UIColor redColor];

    NSArray *actionSheetButtons = actionSheet.subviews;
    for (int i = 0; [actionSheetButtons count] > i; i++) {
        UIView *view = (UIView*)[actionSheetButtons objectAtIndex:i];
        if([view isKindOfClass:[UIButton class]]){
            UIButton *btn = (UIButton*)view;
            [btn setTitleColor:tintColor forState:UIControlStateNormal];

        }
    }
}

要运行此 AFTER ，您可以致电

[actionSheet showInView];

如果在[showInView]之前调用它，则除了取消按钮之外的所有按钮都将被着色。希望这有助于某人！

If you call it before [showInView], all buttons but the cancel button will be colored. Hope this helps someone!
