Setting custom UITableViewCells height

📚 How to Set Custom UITableViewCells Height

Are you struggling with setting the height of your custom UITableViewCell based on the content inside it? Well, you're not alone! Many developers face this issue when dealing with dynamic content that requires a variable cell height. But worry not, because in this blog post, I'll walk you through the common problems and provide easy solutions to set custom heights for your UITableViewCells. So, let's dive in! 💪

The Problem

Imagine you have a custom UITableViewCell with labels, buttons, and image views to be displayed. One of the labels in the cell contains a NSString object, and its length can vary. You want the cell's height to depend on the label's height, which can be determined using the NSString's sizeWithFont method. However, you're encountering issues while implementing this approach.

The Code

Here's an example of how the cell is being initialized:

- (instancetype)initWithFrame:(CGRect)frame reuseIdentifier:(NSString *)reuseIdentifier
{
    if (self = [super initWithFrame:frame reuseIdentifier:reuseIdentifier])
    {
        self.selectionStyle = UITableViewCellSelectionStyleNone;
        
        // Initialization code for other UI elements
        
        // The label causing the height issue
        textView = [[UILabel alloc] initWithFrame:CGRectMake(55.0,42.0,245.0,ht)];
        
        // Additional setup for the label
        
        // Adding UI elements to the cell's contentView
        
        [self.contentView addSubview:textView];
        [self.contentView sizeToFit];
        
        // Release statements
    }
    return self;
}

The Solution

To fix the problem, we need to calculate the correct height for the label dynamically. Here's how you can do it:

1. Measure the text's size using the sizeWithFont method, similar to what you were already attempting:

   CGSize textSize = {245.0, 20000.0}; // Set the desired width and a large enough height CGSize size = [text1 sizeWithFont:[UIFont systemFontOfSize:11.0] constrainedToSize:textSize lineBreakMode:UILineBreakModeWordWrap];

2. Determine the maximum height required for the label, so it can properly accommodate the text and any necessary styling. For example:

   CGFloat maxHeight = MAX(size.height, 28);

3. Update the frame of the label using the calculated height:

   textView.frame = CGRectMake(55.0, 42.0, 245.0, maxHeight);

And that's it! With these changes, your label's height should now adjust correctly based on the size of the text it contains.

Conclusion

Setting custom UITableViewCells height doesn't have to be a headache anymore! By following these simple steps, you can ensure that your dynamic content is properly displayed within your custom cells. So, go ahead and implement these changes in your project to solve the height issue you were facing.
