自定義一個(gè)和京東一樣的效果的UIAlertView

京東-退出登錄原型圖

今天無(wú)意間逛京東商城，退出賬號(hào)時(shí)候，看到京東的這個(gè)彈出框，和系統(tǒng)彈框很像，但是有不太一樣。于是乎就寫了一個(gè)自定義的UIAlertView，和京東這個(gè)彈框動(dòng)畫效果一樣。而且把點(diǎn)擊事件直接分裝在init方法中，使用方便，還做了文本多行適配高度的處理。
寫了這樣一個(gè)彈框的demo，之后遇到彈框這種UI，其實(shí)寫法都是一樣的，只不過(guò)把里面的控件換一下，就可以成為一個(gè)新的彈框界面，代碼可塑性很高。話不多說(shuō)了了，直接上代碼，代碼注釋也都寫了，有什么問(wèn)題，留言給我。

用法如下：

  SPAlertView *alertView = [[SPAlertView alloc]initWithTitle:@"你好，這是一個(gè)測(cè)試，莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌莫驚慌111" cancelButtonTitle:@"取消" doneButtonTitle:@"刪除" cancleBlock:^{
        DDLog(@"點(diǎn)擊取消");
    } doneBlock:^{
        DDLog(@"點(diǎn)擊刪除");
    }];
    [alertView show];
