iPhone SDK: how to get the value of a UITextField in an alert?

由 情到浓时终转凉″ 提交于 2019-12-24 07:45:36
问题 I'm really new at this. I've been working my way through a couple of "HelloWorld" type tutorials that basically have a text field, a button, and when you click the button it alerts whatever's in the text field. I've gotten as far as getting an alert to show and being able to set the title, message, and button text directly. However my attempts at getting the contents of my UITextField keep failing. I either get errors, no response, or just "(null)". My code's here. @synthesize textField; -

关于iOS 7以后自定义UIAlertview(CustomIOS7AlertView)的用法心得

由 不问归期 提交于 2019-12-24 05:25:59
公司项目要求更新的提示框上要加明更新的内容，如下图所示： 但是用系统自带的UIAlertview 却偏偏成为了这个样子！ 不对称很难看有木有！ 故从网上搜寻如何能使message的text左对齐 找到如下： http://blog.csdn.net/andypan1314/article/details/8246407 经调试，发现根本在iOS 8 上不起作用（实际上7.0以后都不起作用） 于是乎决定采用自定义的方式来构建这个提示框，然后去github上去搜了搜，发现了CustomIOS7AlertView 这个第三方的定制控件，地址如下： https://github.com/wimagguc/ios-custom-alertview 运行demo发现，这个能够自己定制alertview上的containerView来实现自己想要的效果。 但是我发现他的按钮跟按钮直接是没有那根分割线的，如下图： 这样就有点太难看了，所以我对他的源代码，做了一些修改，在 CustomIOS7AlertView.m 中找到 这个方法添加如下几行代码（颜色粗细自己写） 再运行下demo试试，就变成了这个样子： 接下来就是嵌入到公司项目中去了，我的思路就是把“提示的title”还有“主title”跟 “更新信息” 放到一个view 上 然后用 方法来显示 具体用法如下： 先导入文件 到工程中

问题 I have a UIAlertView which appears as a confirmation when a user wants to delete a RegionAnnotation. I'm having trouble figuring out how to access the RegionAnnotationView that called the UIAlertView which I need in order to delete the RegionAnnotation.
