iOS开发-UIActionSheet和UIAlertController

本文主要是介绍iOS开发-UIActionSheet和UIAlertController，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

ActionSheet

- (void)buttonPressed:(id)sender
{/**UIActionSheet已经在8.3后被弃用了，如果想要去掉警告信息，可以把项目的Deployment Target设置为8.3以下，就可以去掉警告了。*//**Title:如果不想要title，可以设置为nil；注意需要实现UIActionSheetDelegate；destructiveButtonTitle:设置的按钮文字是红色的；otherButtonTitles：按照按钮顺序；*/UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"这是标题" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:@"确定" otherButtonTitles:nil];/***UIActionSheetStyleAutomaticUIActionSheetStyleDefaultUIActionSheetStyleBlackTranslucentUIActionSheetStyleBlackOpaque*///这里的actionSheetStyle也可以不设置；actionSheet.actionSheetStyle = UIActionSheetStyleAutomatic;[actionSheet showInView:self.view]; }

AlertController

- (void)buttonPressed1:(id)sender
{NSLog(@"dianji");// 初始化提示框UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"提示" message:@"Message" preferredStyle:UIAlertControllerStyleActionSheet];[alert addAction:[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {NSLog(@"点击确定");}]];[alert addAction:[UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {NSLog(@"点击取消");}]];[self presentViewController:alert animated:true completion:nil];
}
