我在tableVIew单元格中添加图片,但它没有显示。 我正在使用if条件将图像赋予按钮,但它没有显示。
以下是按钮添加的代码
addButton = [UIButton buttonWithType:UIButtonTypeCustom];
addButton.Frame=CGRectMake(590,2,42,42);
[addButton addTarget:self action:@selector(tab1Action:) forControlEvents:UIControlEventTouchUpInside];
addButton.tag=indexPath.row;
NSString*test=theData.Status;
if ([test isEqualToString:@"1"]) {
test=@"Already Member of the group";
}
else {
test=@"";
NSLog(@"Else is also Working Fine");
[addButton setImage:[UIImage imageNamed:@"addbutton.png"] forState:UIControlStateNormal];
}
addButton.clipsToBounds=YES;
[[cell contentView] addSubview:addButton];
cell.textLabel.font=[UIFont fontWithName:@"Helvetica" size:16];
cell.textLabel.text=[NSString stringWithFormat:@"%@: %@",theData.GroupTitle,test];
return cell;

您无需添加到单元格的内容视图。所以这样做..
[cell addSubview:addButton];
答案 1 :(得分:0)
您的按钮框架CGRectMake(590,2,42,42)
是错误
frame.origin.x
太大于屏幕尺寸
在开发中只有320,480的大小
640,960是自动的

//为app的不同部分创建一个表
(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString * CellIdentifier = @“Cell”;
UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(!cell){
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
/ *重要提示:由于我们使用的是“动态类型”,因此当表视图重新加载时,我们必须先删除它 容器中的视图。 * /
if([cell.contentView subviews]){ for((cell.contentView子视图)中的UIView *子视图){ [subview removeFromSuperview]; } }
//为图像视图创建一个矩形框 UIImageView * iconImage = [[UIImageView alloc] init]; iconImage.frame = CGRectMake(12,4,53.5,53.5);
//为单元格创建标签 UILabel * cellName = [[UILabel alloc] initWithFrame:CGRectMake(75,18,200,20)]; cellName.font = [self fontForBodyTextStyle];
NSString * cellNameStr = [NSString stringWithFormat:@“%@”,self.tableCellNames [indexPath.row]];
//选择路径行选项卡操作 switch(indexPath.row){ 案例0:
cellName.text = cellNameStr;
iconImage.image = [UIImage imageNamed:@"condition.png"];
[cell.contentView addSubview:iconImage];
[cell.contentView addSubview:cellName];
break;
case 1:
cellName.text = cellNameStr;
iconImage.image = [UIImage imageNamed:@"videos.png"];
[cell.contentView addSubview:iconImage];
[cell.contentView addSubview:cellName];
break;
case 2:
cellName.text = cellNameStr;
iconImage.image = [UIImage imageNamed:@"provider.png"];
[cell.contentView addSubview:iconImage];
[cell.contentView addSubview:cellName];
break;
case 3:
cellName.text = cellNameStr;
iconImage.image = [UIImage imageNamed:@"info.png"];
[cell.contentView addSubview:iconImage];
[cell.contentView addSubview:cellName];
break;
default:
NSAssert(NO, @"Unhandled value in cellForRowAtIndexPath");
break;
}
返回细胞; } 谢谢VKJ,
