Dynamic UITableView Cell Height Based on Contents

Question

I have a UITableView that is populated with custom cells (inherited from UITableViewCell), each cell contains a UIWebView that is auto

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.
