Custom UITableView Dynamic Cell Height

Question

I have search and searched through endless blogs and articles on how to determine a dynamic height for a custom UITableViewCell and its detailed text. I have really had a hard t

Answer 1

I tried many solutions, but the one that worked was this, suggested by a friend:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {

    int height = [StringUtils findHeightForText:yourLabel havingWidth:yourWidth andFont:[UIFont systemFontOfSize:17.0f]];

    height += [StringUtils findHeightForText:yourOtherLabel havingWidth:yourWidth andFont:[UIFont systemFontOfSize:14.0f]];

    return height + CELL_SIZE_WITHOUT_LABELS; //important to know the size of your custom cell without the height of the variable labels
}

The StringUtils.h class:

 #import 

    @interface StringUtils : NSObject

    + (CGFloat)findHeightForText:(NSString *)text havingWidth:(CGFloat)widthValue andFont:(UIFont *)font;

    @end

StringUtils.m class:

    #import "StringUtils.h"

    @implementation StringUtils

    + (CGFloat)findHeightForText:(NSString *)text havingWidth:(CGFloat)widthValue andFont:(UIFont *)font {
        CGFloat result = font.pointSize+4;
        if (text) {
            CGSize size;

            CGRect frame = [text boundingRectWithSize:CGSizeMake(widthValue, CGFLOAT_MAX)
                                              options:NSStringDrawingUsesLineFragmentOrigin
                                           attributes:@{NSFontAttributeName:font}
                                              context:nil];
            size = CGSizeMake(frame.size.width, frame.size.height+1);
            result = MAX(size.height, result); //At least one row
        }
        return result;
    }

    @end

It worked perfectly for me. I had a Custom Cell with 3 images with fixed sizes, 2 labels with fixed sizes and 2 variable labels. Worked like a charm. Hope it works for you too.

Best regards, Alexandre.
