Question

我有一个应用程序，其中 UIScrollView 添加为 UIView 的 subview 。我添加了 UITextField,UITextview 作为 UIScrollView 的 subview 。我想在 ScrollView 中点击时关闭键盘。我该怎么做？

Answer 1

只需添加UITapGestureRecognizer

- (void)viewDidLoad
{
    [super viewDidLoad];
    UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTapGestureCaptured:)];
    [scr addGestureRecognizer:singleTap];
}


- (void)singleTapGestureCaptured:(UITapGestureRecognizer *)gesture
{
    //Get touch point
    CGPoint touchPoint=[gesture locationInView:scr];

    //Hide keyBoard
    [self.view endEditing:YES];
}
