IOS --- UITableViewCell adaptive Row Height (non-AutoLayout)

IOS --- UITableViewCell adaptive Row Height (non-AutoLayout)

As shown in the question, this program uses the UITableView self-adaptive Row Height written by non-AutoLayout, and then I will write a small demo of self-adaptive Row Height Based on AutoLayout.
PS: This applet is only applicable to children who are new to IOS. It is only used for reference and is untechnical.

Code:

// UITableViewCell # import
  
   
@ Interface commentaryCell: UITableViewCell @ property (retain, nonatomic) UILabel * userID; @ property (retain, nonatomic) UILabel * date; @ property (retain, nonatomic) UILabel * commentary; -(void) setContent :( NSString *) userid_dic :( NSString *) date_dic :( NSString *) comment_dic; @ end # import "commentaryCell. h "float width; float height; NSString * commentaryStr; @ implementation commentaryCell @ synthesize userID; @ synthesize date; @ synthesize commentary;-(id) initWithStyle :( UITableViewCellStyle) style reuseIdentifier :( NSString *) reuseIdentifier {self = [super initWithStyle: style reuseIdentifier: reuseIdentifier]; if (self) {self. contentView. backgroundColor = [UIColor whiteColor]; [self createView];} return self;}-(void) createView {width = self. contentView. frame. size. width; height = self. contentView. frame. size. height; // user ID userID = [[UILabel alloc] initWithFrame: CGRectMake (width * 0.05, height * 0.3, width * 0.3, height * 0.3)]; userID. font = [UIFont systemFontOfSize: 14]; [userID setTextColor: [UIColor colorWithRed: 85.0/255.0 green: 85.0/255.0 blue: 85.0/255.0 alpha: 0.6]; [self. contentView addSubview: userID]; // time icon // time date = [[UILabel alloc] initWithFrame: CGRectMake (width * 0.4, height * 0.3, width * 0.5, height * 0.3)]; date. font = [UIFont systemFontOfSize: 14]; [date setTextColor: [UIColor colorWithRed: 85.0/255.0 green: 85.0/255.0 blue: 85.0/255.0 alpha: 0.6]; [self. contentView addSubview: date]; // commentary = [[UILabel alloc] init]; [commentary setNumberOfLines: 0]; commentary. font = [UIFont systemFontOfSize: 16]; [commentary setTextColor: [UIColor colorWithRed: 85.0/255.0 green: 85.0/255.0 blue: 85.0/255.0 alpha: 1]; [self. contentView addSubview: commentary];}-(void) setContent :( NSString *) userid_dic :( NSString *) date_dic :( NSString *) comment_dic {userID. text = userid_dic; date. text = date_dic; [commentary setNumberOfLines: 0]; commentary. text = comment_dic; commentary. font = [UIFont systemFontOfSize: 16]; CGSize commentSize = [self returnSize: commentary. text font: commentary. font]; [commentary setFrame: CGRectMake (width * 0.05, 41, commentSize. width, commentSize. height)];} // return the Size of the Label-(CGSize) returnSize :( NSString *) text font :( UIFont *) font {float width = [UIScreen mainScreen]. bounds. size. width; float height = [UIScreen mainScreen]. bounds. size. height; CGSize _ Size = CGSizeMake (width * 0.9, height); CGSize Size = [text sizeWithFont: font constrainedToSize: _ Size lineBreakMode: NSLineBreakByWordWrapping]; return Size ;}
