如何顯示日曆而不是在iPhone中使用UIDatePicker？

我正在使用UIDatePicker控制器在iPhone應用程序中選擇日期。現在，我想顯示日曆視圖，而不是UIDatePicker控制器。我在谷歌搜索了我的最佳水平。但是，我找不到我的問題的確切解決方案。任何人都可以請幫助使用日曆視圖的UIDatePicker？提前致謝。如何顯示日曆而不是在iPhone中使用UIDatePicker？

最好的方法是使用下面的一個 -

1）https://github.com/guicocoa/calendar

2）http://github.com/devinross/tapkulibrary

3）http://github.com/klazuka/Kal

沒有現成的解決方案，可轉換的UIDatePicker到日曆視圖

@ Yuvaraj.M我個人使用卡爾從Klazuka，我會推薦它。但是它有一個問題：如果你想在選擇一個日期後打開一個新的視圖。所以如果你選擇上一個/下一個月，它會自動選擇那個月的第一天。我嘗試了tapku，但日曆非常混亂。本週的日期和日期不正確。也許它現在已經修復了，幾個月前我檢查過了。 – Novarg

@Novarg謝謝。我會檢查並儘快回覆。謝謝。 –

創建一個collectionview和用戶此單元格爲d isplay日曆。
