I have a Tableview Controller, in that there are 9 rows are there. All are static rows, and in row having counts of tickets, so I want to update it dynamically, whenever data changes in that data also want to change here,also I want to update image. So How I can do it...!
我有一个Tableview控制器，因为有9行。所有都是静态行，并且在行中有票数，所以我想动态更新它，只要数据中的数据更改也想在这里更改，我也想更新图像。那我该怎么做......！
It updates but, every time we have to build it..then values count will update..! SO following screen shot..!
它更新，但每次我们必须建立它..然后值数将更新..！以下屏幕截图..！
