在表格视图中删除时，如何删除确认按钮的阴影？

Question

在表格视图中删除时，如何删除确认按钮的阴影？

Answer 1

首先，只需打开故事板，单击按钮一次以选择它，然后通过单击蓝色箭头将阴影颜色设置为默认：

在override func ViewDidLoad()：

中以编程方式尝试以下操作

    self.buttonOutlet.layer.shadowColor = UIColor.white.cgColor
    self.buttonOutlet.layer.shadowOffset = CGSize(width: 0, height: 0)
    self.buttonOutlet.layer.shadowRadius = 0
    self.buttonOutlet.layer.shadowOpacity = 0

将buttonOutlet替换为按钮插座的实际名称。

如果有帮助，请告诉我:)。

我确实解决了这个问题，我们可以自定义这个按钮。 处理TableViewCell。

-(void)layoutIfNeeded {
    [super layoutIfNeeded];
    if ([self.subviews count] >= 4){
        for(UIView* subView in self.subviews){
            //DDLogDebug(@"JARED: subView %@",[subView class]);
            if([NSStringFromClass([subView class]) isEqualToString:@"UITableViewCellEditControl"]){
                for(UIView * subView2 in subView.subviews){

                    if ([subView2 isKindOfClass: [UIImageView class]] && subView2.frame.origin.y == 20) {
                        subView2.layer.shadowRadius  = 11;
                        subView2.layer.shadowColor   = [UIColor whiteColor].CGColor;
                        subView2.layer.shadowOffset  = CGSizeMake(0.0f, 0.0f);
                        subView2.layer.shadowOpacity = 0.1;
                        subView2.layer.cornerRadius  = 11;
                        subView2.layer.masksToBounds = NO;
                        subView2.layer.backgroundColor = [UIColor whiteColor].CGColor;
                        subView2.layer.contents = (id)[UIImage imageNamed:@"confirmDetele"].CGImage;


                    }
                    if ([subView2 isKindOfClass: [UIImageView class]] && subView2.frame.origin.y == 22) {

                        subView2.layer.contents = nil;
                        subView2.layer.shadowRadius  = 11;
                        subView2.layer.shadowColor   = [UIColor whiteColor].CGColor;
                        subView2.layer.shadowOffset  = CGSizeMake(0.0f, 0.0f);
                        subView2.layer.shadowOpacity = 0.1;
                        subView2.layer.cornerRadius  = 11;
                        subView2.layer.masksToBounds = NO;
                        subView2.layer.backgroundColor = [UIColor whiteColor].CGColor;


                    }

                }
            }
        }
    }

}
