我在tableviewcells中有UITextFields。当您滑动单元格而不是文本字段的一部分时,删除操作会按预期显示。如果您在文本字段上滑动,则会停止删除弹出窗口。
如何解决这个问题,以便您可以滑动输入,单元格会触发删除操作?

我认为这里的问题是文本字段上的触摸会干扰您的滑动手势识别器(可能附加到父视图)。我在UIScrollView中放置了一个类似的文本字段问题。
我通过在我的UITextField上覆盖一个清晰的UIView解决了这个问题。然后,我将UITapGestureRecognizer分配给此清晰视图,以便在用户点击该字段时将文本字段设置为第一个响应者。否则,滑动被发送到父视图(滚动视图),该视图识别滑动而没有任何问题。它有点蹩脚,但它有效。
这种情况与您的情况略有不同,但我认为这是同样的问题。这是我的代码看起来像,希望它有所帮助:
// UIView subclass header
@interface LSAddPageView : UIView
@property (weak, nonatomic) IBOutlet UITextField *textField; // Connected to the UITextField in question
@property (strong, nonatomic) UIView *textFieldMask;
@property (assign, nonatomic) BOOL textFieldMaskEnabled;
@end
// UIView subclass implementation
@implementation LSAddPageView
- (void)awakeFromNib
{
[super awakeFromNib];
_textFieldMask = [UIView new];
_textFieldMask.backgroundColor = [UIColor clearColor];
[self insertSubview:_textFieldMask aboveSubview:self.textField];
}
- (void)layoutSubviews
{
[super layoutSubviews];
_textFieldMask.frame = self.textField.frame;
}
- (BOOL)textFieldMaskEnabled
{
return _textFieldMask.hidden == NO;
}
- (void)setTextFieldMaskEnabled:(BOOL)textFieldMaskEnabled
{
_textFieldMask.hidden = !textFieldMaskEnabled;
}
@end
然后在控制器中:
- (void)viewDidLoad
{
[super viewDidLoad];
_addPageView = (LSAddPageView*)self.view;
_maskGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(didTapMask:)];
_maskGestureRecognizer.numberOfTapsRequired = 1;
_maskGestureRecognizer.numberOfTouchesRequired = 1;
[_addPageView.textFieldMask addGestureRecognizer:_maskGestureRecognizer];
self.textField.delegate = self; // Set delegate to be notified when text field resigns first responder
}
- (void)didTapMask:(UIGestureRecognizer*)recognizer
{
_addPageView.textFieldMaskEnabled = NO;
[self.textField becomeFirstResponder];
}
- (BOOL)textFieldShouldEndEditing:(UITextField *)textField
{
_addPageView.textFieldMaskEnabled = YES;
return YES;
}

听起来你需要设置cancelsTouchesInView
属性
yourGestureRecognizer.cancelsTouchesInView = NO;

来自UIButton & UITextField will block UITableViewCell being swipe to delete
self.tableView.panGestureRecognizer.delaysTouchesBegan = YES;
这将使文本字段不会停止向左滑动客户
