I am trying to create one UITableView with n number of buttons depends on backend JSON data.

我附上了一张图片，我知道如何在 UITableViewCell 上创建 UIButton，但我不知道如何将它们正确放置在 UITableViewCell 中.

I have attached an image, i know how to create UIButtons on UITableViewCell but i don't know how to place them correctly inside UITableViewCell.

UIButton for UITableViewCell

UIButton *continuebtn = [[UIButton alloc]initWithFrame:CGRectMake(10, 100, view1.frame.size.width-20, 40)];
[continuebtn setBackgroundColor:[UIColor grayColor]];
[continuebtn setTitle:@"Continue" forState:UIControlStateNormal];
continuebtn.layer.cornerRadius = 10;
continuebtn.layer.borderWidth =1.0;
continuebtn.layer.borderColor = [UIColor blackColor].CGColor;
[continuebtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];

推荐答案

我自己找到了更好的答案.请检查此代码.

I have found a better answer myself. Please check this code.

  - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    cell = [tableView dequeueReusableCellWithIdentifier:@"cell" forIndexPath:indexPath];

    [cell addSubview:[self addView:indexPath.row]];
    return cell;
}


-(UIView *)addView:(NSInteger)row{

    UIView *progView;
    progView = [[UIView alloc] initWithFrame:CGRectMake(0, 0,cell.frame.size.width,cell.frame.size.height)];
    progView.backgroundColor = [UIColor grayColor];
    progView.tag = i;    
    progView.autoresizingMask = (UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin);

    int x,y;
    x=10;y=10;
    for(int i=0;i<10;i++){
        UIButton *button = [[UIButton alloc]init];
        NSString *myString=@"Dynamic";
        [button setTitle:myString forState:UIControlStateNormal];
        CGSize stringsize = [myString sizeWithFont:[UIFont systemFontOfSize:14]];
        [button setFrame:CGRectMake(x,y,stringsize.width+40, stringsize.height+20)];
        x+=stringsize.width+50;
        NSLog(@"%d-%f",x,progView.frame.size.width);

        if(x>progView.frame.size.width){
            y+=50;
            x=10;
        }

        button.layer.borderWidth =1.0;
        button.layer.borderColor = [UIColor greenColor].CGColor;
        [button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
        [button setTag:i]; 
        [progView addSubview:button];
    }

    return progView;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return 200;
}
