您必须实现 viewForRow 方法才能这样做。

-(UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view {

UILabel *label=[[UILabel alloc]init];
[label setNumberOfLines:NSIntegerMax];
[label setText:[array objectAtIndex:row]];
return label;

}
