IOS UIScrollview不允許鍵盤在觸摸屏幕時關閉

我構建了一個應用程序，當textview被填充時，鍵盤會彈出並允許您鍵入。如果我決定不想使用鍵盤，我可以點擊背景視圖控制器，它會掉下來。現在，我添加了一個滾動視圖。一切工作正常，但我無法獲得連接的操作，並在觸摸Textview外部時使鍵盤掉落。（我不能在Xcode中製作自定義視圖控制器）IOS UIScrollview不允許鍵盤在觸摸屏幕時關閉

有沒有人有任何修復？

預先感謝您！

@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 {

您可以發佈您的代碼？ – Raptor 2015-03-03 04:03:15

感謝您尋找猛禽。我沒有添加代碼，因爲我認爲這是一個Xcode連接問題 – mhinton11 2015-03-03 05:16:13

據我所知，touchbegan函數在滾動視圖中不起作用。每當用戶滾動時都會更好，您可以關閉鍵盤。否則用鍵盤添加一個工具欄按鈕（關閉）。 – 2015-03-03 05:35:00

嘗試UITapGestureRecognizer：

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

和行動：

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