I have an application where I have a pickerview. In that picker I am displaying values from 1 to 100. When I select a value in picker say 2 that value is displayed in a textfield. I want that if my textfield contains value say 5 that value particular value should get displayed in my picker.
我有一个应用程序,我有一个pickerview。在该选择器中,我显示的值为1到100.当我在选择器中选择一个值时,表示该值显示在文本字段中。我希望如果我的文本字段包含值5,那么值特定值应该显示在我的选择器中。
Now problem is when in textfield 5 is displayed and I go to pickerview it shows by default every time 1 selected irrespective of the value in the texfield. I want the value which is present in the textfield should get displayed on the pickerview also.
现在的问题是当在textfield 5中显示并且我进入pickerview时它默认显示每次选择1而不管texfield中的值。我希望文本字段中存在的值也应该显示在pickerview上。
