【解决方案1】：

 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);
}

【讨论】：

我可以使用- (NSInteger)selectedRowInComponent:(NSInteger)component 方法来选择行吗？如果是这样，方法体会是什么样子。我只需要NSLog 选择的值。请帮忙

【解决方案2】：

检查以下内容，

    UIPickerView *pickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 44, 320, 250)];
    pickerView.delegate = self;
    pickerView.dataSource = self;
    pickerView.showsSelectionIndicator = YES;
    pickerView.opaque = NO;
    [customPickerView addSubview:pickerView];

- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView;
{
    return 1;
}
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component;
{
    return 10;
}
 - (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view{
ILabel* tView = (UILabel*)view;
tView.text =  [arrList objectAtIndex:row];
}
- (void)pickerView:(UIPickerView *)thePickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
      //When ever picker view cell is pressed.
      //Write ur logic
}
