ios8 上面,用UIAlertController将UIAlertView和UIActionSheet合二为一了。
(1)创建普通alert
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:title message:message preferredStyle:UIAlertControllerStyleAlert]; // Create the actions. UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:cancelButtonTitle style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) { NSLog(@"The \"Okay/Cancel\" alert‘s cancel action occured."); }]; UIAlertAction *otherAction = [UIAlertAction actionWithTitle:otherButtonTitle style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) { NSLog(@"The \"Okay/Cancel\" alert‘s other action occured."); }]; // Add the actions. [alertController addAction:cancelAction]; [alertController addAction:otherAction]; [self presentViewController:alertController animated:YES completion:nil];
如果UIAlertAction *otherAction这种otherAction多几个的话,它会自动排列成一列。
(2)带有输入框的alert
如果需要在 alertview上面添加输入框等,如下:
[alertController addTextFieldWithConfigurationHandler:^(UITextField *textField) {
// 可以在这里对textfield进行定制,例如改变背景色
textField.backgroundColor = [UIColor orangeColor];
}];
