iphone - 向 UIDatePicker 添加值

Question

我需要将项目添加到 UIDatePicker，而不是添加日期:

我需要添加一个名字列表(例如，“James”)。我该怎么做？

Answer 1

只需使用 UIPickerView

 UIPickerView *myPickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 200, 320, 200)];
 myPickerView.delegate = self
 myPickerView.showsSelectionIndicator = YES;
 [self.view addSubview:myPickerView]; 

  - (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
  {
     return 1;
  }  
  - (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
 {   
      return 1;
 }

  - (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component 
  {
     NSString *string = [NSString stringWithString:@"Jack"];
     return string;
   }

- (NSInteger)selectedRowInComponent:(NSInteger)component
{
      //Returns the index of the selected row in a given component.
      NSLog(@"%d",component);
}
