自定义一个和京东一样的效果的UIAlertView

京东-退出登录原型图


今天无意间逛京东商城,退出账号时候,看到京东的这个弹出框,和系统弹框很像,但是有不太一样。于是乎就写了一个自定义的UIAlertView,和京东这个弹框动画效果一样。而且把点击事件直接分装在init方法中,使用方便,还做了文本多行适配高度的处理。
写了这样一个弹框的demo,之后遇到弹框这种UI,其实写法都是一样的,只不过把里面的控件换一下,就可以成为一个新的弹框界面,代码可塑性很高。话不多说了了,直接上代码,代码注释也都写了,有什么问题,留言给我。

用法如下:

  SPAlertView *alertView = [[SPAlertView alloc]initWithTitle:@"你好,这是一个测试,莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌莫惊慌111" cancelButtonTitle:@"取消" doneButtonTitle:@"删除" cancleBlock:^{
        DDLog(@"点击取消");
    } doneBlock:^{
        DDLog(@"点击删除");
    }];
    [alertView show];
