我的 UIScrollView 没有响应触摸事件，也没有为我的 UIViewController 调用 touchesBegain 方法。（此外，我的按钮上的文字在一个上失真，而在另一个上没有显示）
在 Storyboard 中，我将 ScrollView 添加到 UIViewController 并将我的 UITextFields 和 UIButtons 添加到 ScrollView
这是代码：
#import <UIKit/UIKit.h>
@interface RefineSearchViewController : UIViewController <UITextFieldDelegate, UIScrollViewDelegate>
{
IBOutlet UIScrollView *scroller;
}
@property (strong, nonatomic) IBOutlet UITextField *nameField;
@property (strong, nonatomic) IBOutlet UITextField *targetField;
@property (strong, nonatomic) IBOutlet UITextField *vendorField;
@property (strong, nonatomic) IBOutlet UITextField *CATField;
@property (strong, nonatomic) IBOutlet UITextField *clonalityField;
@property (strong, nonatomic) IBOutlet UITextField *sourceOrganismField;
-(IBAction) textFieldReturn: (id) sender;
#import "RefineSearchViewController.h"
#import "DBHandler.h"
@interface RefineSearchViewController ()
@end
