Ios 更改UIAlertController所选按钮的颜色

我有以下几行代码：

UIAlertController *alertController = [UIAlertController alertControllerWithTitle:title message:nil preferredStyle:UIAlertControllerStyleActionSheet];
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:cancelTitle style:UIAlertActionStyleCancel handler:^(UIAlertAction * action) {
    NSLog(@"cancel registration");
}];
[alertController addAction:cancelAction];
alertController.view.tintColor = [UIColor redColor];

选择时，我想更改取消按钮的颜色。我该怎么做？

请提供帮助。

只需更改

UIAlertController

视图上的色调即可

 UIAlertController *alertController = [UIAlertController alertControllerWithTitle:title message:nil preferredStyle:UIAlertControllerStyleActionSheet];
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:cancelTitle style:UIAlertActionStyleCancel handler:^(UIAlertAction * action) {
    NSLog(@"cancel registration");
     alertController.view.tintColor = [UIColor redColor];
}];
[alertController addAction:cancelAction];

试试这个

Swift

   {
        // Bugfix: iOS9 - Tint not fully Applied without Reapplying
        alertController.view.tintColor = UIColor.redColor()
    }

var alertController: UIAlertController = UIAlertController.alertControllerWithTitle(title, message: nil, preferredStyle: .ActionSheet)
var cancelAction: UIAlertAction = UIAlertAction.actionWithTitle(cancelTitle, style: .Cancel, handler: {(action: UIAlertAction) -> Void in
    NSLog("cancel registration")
})
alertController.addAction(cancelAction)

目标-C

   {
        // Bugfix: iOS9 - Tint not fully Applied without Reapplying
        alertController.view.tintColor = [UIColor redColor];
    }

有关更多详细信息，请尝试此

UIAlertController *alertController = [UIAlertController alertControllerWithTitle:title message:nil preferredStyle:UIAlertControllerStyleActionSheet];
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:cancelTitle style:UIAlertActionStyleCancel handler:^(UIAlertAction * action) {
NSLog(@"cancel registration");
}];
[alertController addAction:cancelAction];

在呈现警报控制器后，尝试设置色调颜色：

Swift

   {
        // Bugfix: iOS9 - Tint not fully Applied without Reapplying
        alertController.view.tintColor = UIColor.redColor()
    }

var alertController: UIAlertController = UIAlertController.alertControllerWithTitle(title, message: nil, preferredStyle: .ActionSheet)
var cancelAction: UIAlertAction = UIAlertAction.actionWithTitle(cancelTitle, style: .Cancel, handler: {(action: UIAlertAction) -> Void in
    NSLog("cancel registration")
})
alertController.addAction(cancelAction)

你是否检查了此链接@jithin我检查了此链接，但选中按钮后，tintColor将更改为默认颜色。我的问题是关于所选按钮的颜色。我也写了这行，但当按钮被选中时，色调颜色变成默认颜色。这是iOS 9和Xcode 7.0.1中的错误，您可以在Xcode 7.1和iOS 9.1及以上版本中检查它不起作用@Anbu.Karthik，我尝试了这个版本，直到问问题，我有Xcode 7.1和iOS 9.1。这个代码是swift而不是objective-c:）@Ferrakkem Bhuiyanhave Good day我的朋友，同时@Ferrakkem Dundan，Bhumica的答案也正确，如果我的答案运行良好，请投反对票，这对未来很有用当我说“谢谢”时，我给了你投票权：）@Anbu.Karthik
