在UItableviewCell上设置的图像

Question

我有三张图片：正常，突出显示和选中。如何在Tableview自定义单元格中进行设置？

我试过这个：

- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
    if (selected) {
        self.highlighted = NO;
        self.imgBackgroundCell.image = [UIImage imageNamed:[MTUtility setImageWithName:@"listselected"]];
    }

} 
- (void)setHighlighted:(BOOL)highlighted animated:(BOOL)animate {
    if (highlighted) {
        self.imgBackgroundCell.image = [UIImage imageNamed:[MTUtility setImageWithName:@"listpressed"]];
    }
}

但突出显示仍有很多次。

Answer 1

尝试更新您的代码：

- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
    if (selected) {
        self.highlighted = NO;
        self.imgBackgroundCell.image = [UIImage imageNamed:[MTUtility setImageWithName:@"listselected"]];
    }
    else{
       ...unselect code
    }

} 
- (void)setHighlighted:(BOOL)highlighted animated:(BOOL)animate {
    if (highlighted) {
        self.imgBackgroundCell.image = [UIImage imageNamed:[MTUtility setImageWithName:@"listpressed"]];
    }
    else{
      ...unhighlight
    }
}

如果您想要didselectrowatindexpath上的所选图像，那么您可以在cellForRowAtIndexPath方法中设置UITableviewCell属性setSelectedBackgroundView，如下所示：

    - (UITableViewCell*)tableView:(UITableView*)tableView cellForRowAtIndexPath:(NSIndexPath*)indexPath{
{
....
UIImageView *normalCellBG = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, cell.frame.size.width, cell.frame.size.height)];

[normalCellBG setImage:[UIImage imageNamed:@"box_nonselected.png"]];//Set Image for Normal
[normalCellBG setBackgroundColor:[UIColor clearColor]];
[cell setBackgroundView:normalCellBG];


UIImageView *selecetedCellBG = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, cell.frame.size.width, cell.frame.size.height)];
[selecetedCellBG setImage:[UIImage imageNamed:@"box_selected.png"]];//Set Name for selected Cell
[selecetedCellBG setBackgroundColor:[UIColor clearColor]];
[cell setSelectedBackgroundView:selecetedCellBG ];

}

如果您需要这样做，请告诉我。
