一个视图中的两个textfield的两个采样器

Question

我有两个文本字段。每个人都有自己的选择器视图。当用户点击其中每个人时，UIPickerView出现。一切正常。但是，首先当我点击第二个文本字段时，出现第二个文本字段的选取器视图，第一个文本字段从此选取器视图中获取结果，而不是第二个文本字段。有些东西在我的代码中不正确。我无法弄清楚究竟是什么。事先请帮助...谢谢）

Answer 1

你可以给名称以采摘，然后区分它们的 前Picker1和picker2和didselectrow把条件

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { 

    if(pickerview == picker1) 
{ 
reminderString =[myArray objectAtIndex:row]; 
     [reminder setText:reminderString]; 
} 

elseif(pickerview == picker2) 
{ 

    reminderString =[myArray objectAtIndex:row]; 
     [repetition setText:reminderString]; 
}
