iOS实现根据返回数据改变cell元素的坐标位置

实现类似于一下设计稿的需求:

其中 认证 商铺 资质 这三个控件会根据后端数据来决定是否会显示.其中任何一个都有可能没有

我们可以在VC中的cellForRow方法里面编写代码,通过判断来改变控件的位置,但是将代码全部写入VC中显得过于繁杂,我们可以参照改变cell中label的高度的方法,将改变的方法写到自定义cell中

可以看下下面的代码:

1,写在VC中的代码

- (void)viewDidLoad {
    [super viewDidLoad];
    self.view.backgroundColor = BGROUND_COLOR;
    self.title = @"测试cell";
    
    _testArray = @[@[@"0",@"1",@"1"],@[@"1",@"0",@"1"],@[@"1",@"1",@"0"],@[@"0",@"0",@"1"],@[@"1",@"0",@"0"],@[@"0",@"1",@"0"]];
    
    _testTableView = [[UITableView alloc] initWithFrame:self.view.bounds style:UITableViewStylePlain];
    _testTableView.dataSource = self;
    _testTableView.delegate = self;
    [self.view addSubview:_testTableView];
}

#pragma mark - <UITableViewDelegate,UITableViewDataSource>

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
    return _testArray.count;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    static NSString *cellString = @"cellString";
    TestTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellString];
    if (!cell) {
        cell = [[TestTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellString];
    }
    NSArray *arr = _testArray[indexPath.row];
    [cell moveViewWithLeft:arr[0] mid:arr[1] right:arr[2]];
    
    cell.leftLabel.text = @"左侧";
    cell.midLabel.text = @"中间";
    cell.rightLabel.text = @"右侧";
    
    return cell;
}

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
    return 110;
}

自定义cell的代码

@property (nonatomic, strong) UIView *leftView;
@property (nonatomic, strong) UILabel *leftLabel;

@property (nonatomic, strong) UIView *midView;
@property (nonatomic, strong) UILabel *midLabel;

@property (nonatomic, strong) UIView *rightView;
@property (nonatomic, strong) UILabel *rightLabel;

@property (nonatomic, strong) UIView *tempView;

- (void)moveViewWithLeft:(NSString *)left mid:(NSString *)mid right:(NSString *)right;

-(instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier{
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {
        self.leftView = [[UIView alloc] initWithFrame:CGRectMake(10, 10, 100, 40)];
        self.leftView.backgroundColor = [UIColor redColor];
        self.leftView.clipsToBounds = YES;
        [self addSubview:self.leftView];
        
        self.leftLabel = [[UILabel alloc] initWithFrame:self.leftView.bounds];
        self.leftLabel.textColor = [TncTool colorWithHexString:@"333333"];
        self.leftLabel.textAlignment = 1;
        self.leftLabel.font = [UIFont systemFontOfSize:15];
        [self.leftView addSubview:self.leftLabel];
        
        self.midView = [[UIView alloc] initWithFrame:CGRectMake(self.leftView.right + 10, 10, 100, 40)];
        self.midView.backgroundColor = [UIColor blueColor];
        self.midView.clipsToBounds = YES;
        [self addSubview:self.midView];
        
        self.midLabel = [[UILabel alloc] initWithFrame:self.midView.bounds];
        self.midLabel.textColor = [TncTool colorWithHexString:@"333333"];
        self.midLabel.textAlignment = 1;
        self.midLabel.font = [UIFont systemFontOfSize:15];
        [self.midView addSubview:self.midLabel];
        
        self.rightView = [[UIView alloc] initWithFrame:CGRectMake(self.midView.right + 10, 10, 100, 40)];
        self.rightView.backgroundColor = [UIColor yellowColor];
        self.rightView.clipsToBounds = YES;
        [self addSubview:self.rightView];
        
        self.rightLabel = [[UILabel alloc] initWithFrame:self.rightView.bounds];
        self.rightLabel.textColor = [TncTool colorWithHexString:@"333333"];
        self.rightLabel.textAlignment = 1;
        self.rightLabel.font = [UIFont systemFontOfSize:15];
        [self.rightView addSubview:self.rightLabel];
        
        self.tempView = [[UIView alloc] initWithFrame:CGRectMake(10, 60, WINDOW_WIDTH - 20, 40)];
        self.tempView.backgroundColor = [UIColor purpleColor];
        [self addSubview:self.tempView];
    }
    return self;
}

    if ([left isEqualToString:@"0"]) {

最后效果:

简直简单的一腿儿~
