IOS UIScrollview不允许键盘在触摸屏幕时关闭

问题描述：

我构建了一个应用程序，当textview被填充时，键盘会弹出并允许您键入。如果我决定不想使用键盘，我可以点击背景视图控制器，它会掉下来。现在，我添加了一个滚动视图。一切工作正常，但我无法获得连接的操作，并在触摸Textview外部时使键盘掉落。（我不能在Xcode中制作自定义视图控制器）IOS UIScrollview不允许键盘在触摸屏幕时关闭

有没有人有任何修复？

预先感谢您！

@interface ViewController() 
@property (weak, nonatomic) IBOutlet UITextField *actionField; 
@property (weak, nonatomic) IBOutlet UITextField *impactField; 
@property (weak, nonatomic) IBOutlet UITextField *resultField; 

@end 

@implementation ViewController 

- (NSString *)dataFilePath 
{ 
NSArray *paths = NSSearchPathForDirectoriesInDomains(



    NSDocumentDirectory, NSUserDomainMask, YES); 
    NSString *documentsDirectory = [paths objectAtIndex:0]; 
    return [documentsDirectory stringByAppendingPathComponent:@"data.plist"]; 
} 

- (void)viewDidLoad { 
    [super viewDidLoad]; 

    NSString *filePath = [self dataFilePath]; 
    if ([[NSFileManager defaultManager] 
     fileExistsAtPath:filePath]) { 
     NSArray *array = [[NSArray alloc] 
          initWithContentsOfFile:filePath]; 
     for (int i = 0; i < 3; i++) { 
      UITextField *theField = self.lineFields [i]; 
      theField.text = array [i]; 
     } 



} 
    UIApplication *app = [UIApplication sharedApplication]; 
    [[NSNotificationCenter defaultCenter]addObserver:self 
               selector:@selector(applicationWillResignActive:) 
               name:UIApplicationWillResignActiveNotification 
               object:app]; 
} 

    - (void)applicationWillResignActive: 
    (NSNotification *)notification 
    { 
    NSString *filePath = [self 
          dataFilePath]; 
    NSArray *array = [self.lineFields valueForKey:@"text"]; 
    [array writeToFile:filePath atomically:YES]; 

} 


- (void)didReceiveMemoryWarning { 
    [super didReceiveMemoryWarning]; 


} 

- (IBAction)textFieldDoneEditing:(id)sender { 
    [sender resignFirstResponder]; 
} 

- (IBAction)backgroundTap: (id)sender { 
    [self.actionField resignFirstResponder]; 
    [self.impactField resignFirstResponder]; 
    [self.resultField resignFirstResponder]; 
}

您可以发布您的代码？ – Raptor 2015-03-03 04:03:15

感谢您寻找猛禽。我没有添加代码，因为我认为这是一个Xcode连接问题 – mhinton11 2015-03-03 05:16:13

据我所知，touchbegan函数在滚动视图中不起作用。每当用户滚动时都会更好，您可以关闭键盘。否则用键盘添加一个工具栏按钮（关闭）。 – 2015-03-03 05:35:00

答

尝试UITapGestureRecognizer：

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapScrollView:)]; 
[scrollView addGestureRecognizer:singleTap];

和行动：

- (void)tapScrollView:(UITapGestureRecognizer *)gesture { 
    [self.actionField resignFirstResponder]; 
    [self.impactField resignFirstResponder]; 
    [self.resultField resignFirstResponder]; 
}
