Question

我想知道如何最简单地在actionSheet按钮右侧添加复选标记？下面是 Podcasts 应用的屏幕截图。

Answer 1

Note that the solution can crash in a future update to iOS. I'm accessing undocumented private APIs. Such solutions are very fragile. Please see the comments below.

最后我通过使用 UIAlertController 得到了答案:

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

UIAlertAction *firstButton = [UIAlertAction actionWithTitle:@"First Button" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) {
    //click action
}];
[firstButton setValue:[UIColor blackColor] forKey:@"titleTextColor"];
[firstButton setValue:[UIColor blackColor] forKey:@"imageTintColor"];
[firstButton setValue:@true forKey:@"checked"];

UIAlertAction *secondButton = [UIAlertAction actionWithTitle:@"Second Button" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) {
    //click action
}];
[secondButton setValue:[UIColor blackColor] forKey:@"titleTextColor"];

UIAlertAction *cancelButton = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel handler:^(UIAlertAction *action){
    //cancel
}];
[cancelButton setValue:[UIColor blackColor] forKey:@"titleTextColor"];

[customActionSheet addAction:firstButton];
[customActionSheet addAction:secondButton];
[customActionSheet addAction:cancelButton];

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

这是结果:
