Ios 自定义TableViewCell中的UIButton在选择时不更改值
感谢@jsetting32，我有了一个自定义的Ios 自定义TableViewCell中的UIButton在选择时不更改值,ios,objective-c,parse-platform,uibutton,pfobject,Ios,Objective C,Parse Platform,Uibutton,Pfobject,感谢@jsetting32，我有了一个自定义的UITableViewCell，在tableView的底部有按钮。但是，当我单击这些按钮时，selectedState的值没有改变，这使得最终用户很难判断他们是否单击了它 self.likeButton = [UIButton buttonWithType:UIButtonTypeCustom]; [self.likeButton addTarget:self action:@selector(didTapLikeButtonAction:) for
UITableViewCellself.likeButton = [UIButton buttonWithType:UIButtonTypeCustom];
[self.likeButton addTarget:self action:@selector(didTapLikeButtonAction:) forControlEvents:UIControlEventTouchUpInside];
[self.likeButton setTitle:@"Pray" forState:UIControlStateNormal];
[self.likeButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[self.likeButton setTitleColor:[UIColor blueColor] forState:UIControlStateSelected];
[[self.likeButton titleLabel] setFont:[UIFont fontWithName:@"Verdana" size:12.0f]];
[self.cellView addSubview:self.likeButton];
尝试
UIControlStateHighlightedUIControlStateSelected[self.likeButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[self.likeButton setTitleColor:[UIColor blueColor] forState:UIControlStateHighlighted];
下面是我如何解决按钮问题的。。。您的自定义单元格中应该已经有一个方法可以设置类似的状态。。。事情是这样安排的
