如何在UIPickerView上獲取文本？

Question

如果我使用帶有自定義View的UIPickerView（3個組件）。如何從每個selectedRow獲取UIPickerView上的每個文本？

感謝...

Answer 1

您可以使用選擇器的委託方法

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

{ 

    if(component==0) 
    { 
     int i=row;  //here i returns the row selected by you in picker component 0 
    } 
    else if(component==1) 
    { 
     int j=row;  //here j returns the row selected by you in picker component 1 
    } 
    else if(component==2) 
    { 
     int k=row;  //here k returns the row selected by you in picker component 2 
    } 

} 

Answer 2

這取決於您如何決定將文本放置到組件中。

例如，如果你使用myArray：

-(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component 
{ 
    NSLog(@"%@",[myArray objectAtIndex:row]); 
}
