UIAlertView中没有取消按钮？ [英] UIAlertView without Cancel Button?

问题描述

我想创建一个有3个选项，并没有取消按钮UIAlertView中，但我这样做的时候，它总是样式按钮3作为一个取消按钮。有没有什么办法避免这种情况？

  UIAlertView中* alertView = [[UIAlertView中页头] initWithTitle：@选择一项消息：无委托：自我cancelButtonTitle：无otherButtonTitles：@按钮1，@按钮2 @按钮3，零]
 

解决方案

<一个href=\"http://stackoverflow.com/questions/4456675/change-position-of-cancel-button-in-uialertview\">This是关于如何改变取消按钮的位置后。另外，如果您有只有1按钮 UIAlertView中，然后设置：

  _alertView.cancelButtonIndex = -1;
 

可否使按钮显示为一个非取消型按钮。至于我可以告诉虽然，一旦你有超过1键， UIAlertView中强制最后一个按钮是取消按钮。翻翻<一个href=\"http://developer.apple.com/library/ios/#documentation/uikit/reference/UIAlertView_Class/UIAlertView/UIAlertView.html\">reference可能会给你一个有关如何设置属性上来实现这一线索，但我也不太清楚。希望帮助！

I am trying to create a UIAlertView that has 3 options and no "cancel" button, but when I do this, it always styles "Button 3" as a cancel button. Is there any way to avoid this?

UIAlertView *alertView= [[UIAlertView alloc] initWithTitle:@"Select One" message:nil delegate:self cancelButtonTitle:nil otherButtonTitles:@"Button 1",@"Button 2", @"Button3", nil];

解决方案

This is a post about how to change the position of the cancel button. Also, if you have only 1 button in the UIAlertView, then setting:

_alertView.cancelButtonIndex = -1;

Will make the button appear as a non-cancel type button. As far as I can tell though, once you have more than 1 button, the UIAlertView forces the last button to be the cancel button. Looking through the reference may give you a clue about how to set the properties up to achieve this, but I'm not too sure. Hope that Helps!
