长标签“......”不会随着文本的其余部分改变颜色

Question

我在UILabel中有一个UITableViewCell。当用户按下该标签时，我会更改该标签的颜色，并在用户再次按下时将其更改回来。 这适用于所有标签，除非此标签太长并且文本被剪切为“......” - LoremIpsum ......

由于某种原因，3个点不会与文本的其余部分一起改变颜色

任何想法如何让它们与其他文本一起改变？ 我这是框架中的一个错误？

// Configure the cell...

if([self.memberships indexOfObject:@(selectedDiscountProgram.uidValue)]!= NSNotFound){
    cell.nameLabel.textColor = RabatOrangeColor;
    [cell.backgroundImageView setImage:[UIImage rectImageWithGradientFromColor:[UIImage colorWithHex:0xDDDDDD] toColor:[UIImage colorWithHex:0xEEEEEE]]];
    [cell.memberButton setImage:[UIImage imageNamed:@"tjek"] forState:UIControlStateNormal];
    cell.memberButton.imageEdgeInsets =UIEdgeInsetsMake(0, 0, 0, 9.0f);
    //cell.memberButton.frame = CGRectMake(cell.memberButton.frame.origin.x, cell.memberButton.frame.origin.y, 36.0, 36.0);
    [cell.memberButton setTitle:[NSString stringWithFormat:@""] forState:UIControlStateNormal];

}else{


    cell.nameLabel.textColor = RabatGrayColor;
    [cell.backgroundImageView setImage:[UIImage rectImageWithGradientFromColor:[UIImage colorWithHex:0xFFFFFF] toColor:[UIImage colorWithHex:0xF0F0F0]]];
    [cell.memberButton setImage:[UIImage imageNamed:@""] forState:UIControlStateNormal];
    [cell.memberButton setTitle:[NSString stringWithFormat:@""] forState:UIControlStateNormal];
    [cell.memberButton setTitleColor:RabatGrayColor forState:UIControlStateNormal];
}

Answer 1

也许你可以在你的自定义单元格中添加一个布尔值来指示像isOrange这样的状态，然后你会有：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    CustomCell *cell = (CustomCell*)[tableView cellForRowAtIndexPath:indexPath];
    if ([cell isOrange]) {
        cell.nameLabel.textColor = RabatGrayColor;
    }else{
        cell.nameLabel.textColor = RabatOrangeColor;
    }
    cell.isOrange = !cell.isOrange;
}

您可以在cellForRowAtIndexPath

中添加相同的代码段

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    ....
    if ([cell isOrange]) {
        cell.nameLabel.textColor = RabatOrangeColor;
    }
    else{
        cell.nameLabel.textColor = RabatGrayColor;
    }
 }

Answer 2

在自定义单元格中添加一个布尔属性，只是为了知道它是否被选中 示例

在您的自定义单元格CustomCell.h文件

中

  #import <UIKit/UIKit.h>

  @interface CustomCell : UITableViewCell
  @property (nonatomic, retain) UILabel *nameLabel;
  ....
  ....
  .... //your other properties for custom cell 
  @property (nonatomic, assign) BOOL isSelected; //add this boolean variable
  @end

CustomCell.m

中的

@synthesize isSelected;

并在初始化时将其设置为

self.isSelected = NO;//because at the beginning no cell is selected

在控制器中，tableview委托方法就像下面这样做

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
  {
      CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell"];
      if(cell == nil)
      {
        cell = [[CustomCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cell"];
      }
      cell.nameLabel.text = @"some long text some long text some long text some long text some long text some long text";
      //....other settings
      cell.selectionStyle = UITableViewCellSelectionStyleNone;
      cell.nameLabel.textColor = [UIColor blackColor]; //initially set to balck color
      return  cell;

  } 

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
 {
     CustomCell *cell = (CustomCell *)[tableView cellForRowAtIndexPath:indexPath]; //get the cell of the selected index path
     if(cell.isSelected)
     {
        cell.isSelected = NO; //if it is selected set it bool to NO and change color to black
        cell.nameLabel.textColor = [UIColor blackColor];
     }
     else
     {
       cell.isSelected = YES;  //initially it is not selected so select it and set bool to YES and change the colour
       cell.nameLabel.textColor = [UIColor orangeColor];
     }

 }
