UITableViewCell上的UILabel

Question

单击单元格时，添加到单元格的标签看起来就像附图中所示，为什么？

这是代码：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 

{
静态的NSString * CellIdentifier = @ “小区”;

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
if (cell == nil) { 
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; 
} 

int section = [indexPath section]; 
int row = [indexPath row]; 

int rowsInLastSections = 0; 
for (int i = 0; i < section; i++) { 
    rowsInLastSections += [self tableView:tableView numberOfRowsInSection:i]; 
} 

Friend *friend = [friendsArray objectAtIndex:row + rowsInLastSections]; 

[friend setIndexPathInTableView:indexPath]; 

NSString *firstName = [[NSString alloc]initWithFormat:@"%@", [friend firstName]]; 
NSString *lastName = [[NSString alloc]initWithFormat:@"%@", [friend lastName]]; 

UIImageView *profileImageView = [[UIImageView alloc]initWithFrame:CGRectMake(5, 5, 50, 50)]; 
[profileImageView setImageWithURL:[NSURL URLWithString:[friend imageUrl]] placeholderImage:[UIImage imageNamed:@"profile_pic_bg@2x.png"]]; 

UILabel *firstNameLabel = [[UILabel alloc]initWithFrame:CGRectMake(65, 10, 230, 20)]; 
UILabel *lastNameLabel = [[UILabel alloc]initWithFrame:CGRectMake(65, 35, 230, 20)]; 
[firstNameLabel setText:firstName]; 
firstNameLabel.backgroundColor = table.backgroundColor; 
[lastNameLabel setText:lastName]; 
lastNameLabel.backgroundColor = table.backgroundColor; 

[cell.contentView addSubview:profileImageView]; 
[cell.contentView addSubview:firstNameLabel]; 
[cell.contentView addSubview:lastNameLabel]; 

cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; 
[cell setSelectionStyle:UITableViewCellSelectionStyleGray]; 

return cell; 

}

后

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
if (cell == nil) { 
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; 
} 

添加此代码，

for(UIView *view in cell.subviews){ 
     if([view isMemberOfClass:[UILabel class]]){ 
      [(UILabel *)view removeFromSuperview]; 
     } 
    }
