UItableViewCell delete buttonには他のカバー層があります

1つ目の解決策:

// Fix for iOS7, when backgroundView comes above "delete" button - (void)willTransitionToState:(UITableViewCellStateMask)state { [super willTransitionToState:state]; [self sendSubviewToBack:self.backgroundView]; dispatch_async(dispatch_get_main_queue(), ^{ [self sendSubviewToBack:self.backgroundView]; }); } - (void)didTransitionToState:(UITableViewCellStateMask)state { [super didTransitionToState:state]; [self sendSubviewToBack:self.backgroundView]; }

第2の解決策:

- (void)layoutSubviews
{
    [super layoutSubviews];

    for (UIView *subview in self.subviews) {

        for (UIView *subview2 in subview.subviews) {

            if ([NSStringFromClass([subview2 class]) isEqualToString:@"UITableViewCellDeleteConfirmationView"]) { // move delete confirmation view

            [subview bringSubviewToFront:subview2];

        }
    }
}

3つ目の解決策:(最も簡単で、最も直接的で、最も有効)

- (void)layoutSubviews
{
    [super layoutSubviews];
    
    if (self.isEditing) {
        [self sendSubviewToBack:self.contentView];
    }
}

第四种解决办法：

- (void) layoutSubviews {
    [super layoutSubviews];

    if ([ [ [UIDevice currentDevice] systemVersion] compare: @"7.0" options: NSNumericSearch] != NSOrderedAscending) {
        if (iOS7 == YES) {
            self.backgroundView.frame = CGRectMake(0, self.backgroundView.frame.origin.y,
                                                   self.backgroundView.frame.size.width, self.backgroundView.frame.size.height);
    }
}
