Answer 1

不是possible/advisable覆盖UIAlertActiontextcolor。您将必须创建自己的视图并根据您的视图呈现它 needs.There 一些第 3 方库可以帮助您实现您想要的。

Answer 2

试试这个不需要使用任何 3rdParty 库

UIAlertController *alertController = [UIAlertController alertControllerWithTitle:nil message:nil preferredStyle:UIAlertControllerStyleActionSheet];

    UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:NSLocalizedString(@"Cancel", @"Cancel action") style:UIAlertActionStyleCancel handler:^(UIAlertAction *action){
        NSLog(@"Cancle Tapped");
        [alertController dismissViewControllerAnimated:YES completion:nil];
    }];

    [alertController addAction:cancelAction];

    UIAlertAction *yesAction = [UIAlertAction actionWithTitle:NSLocalizedString(@"YES", @"YES action") style:UIAlertActionStyleDefault handler:^(UIAlertAction *action){
        NSLog(@"Yes Button Tapped");
    }];

    // Add CheckMark And Change CheckMark Color
    [yesAction setValue:YOUR_COLOUR forKey:@"titleTextColor"];
    [yesAction setValue:YOUR_COLOUR forKey:@"imageTintColor"];

    [alertController addAction:yesAction];

    UIAlertAction *noAction = [UIAlertAction actionWithTitle:NSLocalizedString(@"NO", @"NO action") style:UIAlertActionStyleDefault handler:^(UIAlertAction *action){

    }];

    // Add CheckMark And Change CheckMark Color
    [noAction setValue:YOUR_COLOUR forKey:@"titleTextColor"];
    [noAction setValue:YOUR_COLOUR forKey:@"imageTintColor"];
    [alertController addAction:noAction];

    [self presentViewController:alertController animated:YES completion:nil];

并且如果您想默认设置带有复选标记的任何按钮而不是添加此。

[yesAction setValue:@true forKey:@"checked"];
