의 tableview 셀 IOS에서 labet 텍스트와 셀 높이 확장

Question

- (CGFloat)를 tableView (jQuery과 *)를 tableView heightForRowAtIndexPath (NSIndexPath *) indexPath {

NSString * message =[[chatData objectAtIndex:indexPath.row]valueForKey:@"message"]; 
NSString * message_type = [[chatData objectAtIndex:indexPath.row]valueForKey:@"message_type"]; 

if([[[chatData objectAtIndex:indexPath.row]valueForKey:@"message_type"] isEqualToString:@"0"]){ 
    CGSize sizeText = [self text:message sizeWithFont:[UIFont systemFontOfSize:16] constrainedToSize:CGSizeMake(CGRectGetWidth([UIScreen mainScreen].bounds) - 100, 9999) withLinebreakmode:NSLineBreakByWordWrapping]; 
    CGFloat heightOfRow = sizeText.height + 2 * 7.5f; 
    return heightOfRow + 50; 
} 
else 
    return 225;//message_type 1 3 4 

// return self.chatTable.rowHeight; 

}

- (CGSize) 텍스트 (는 NSString *) 텍스트 sizeWithFont (UIFont *) 폰트 constrainedToSize (CGSize) ConstSize withLinebreakmode (NSLineBreakMode) linebreakmode { CGSize의 retsize;

if ([text respondsToSelector:@selector(boundingRectWithSize:options:attributes:context:)]) 
{ 
    NSMutableParagraphStyle * paragraphStyle = [[NSMutableParagraphStyle alloc] init]; 
    paragraphStyle.lineBreakMode = linebreakmode; 
    // paragraphStyle.alignment = NSTextAlignmentLeft; 
    NSDictionary * attributes = @{NSFontAttributeName : font,NSParagraphStyleAttributeName : paragraphStyle}; 
    retsize = [text boundingRectWithSize:ConstSize options:NSStringDrawingUsesFontLeading 
       |NSStringDrawingUsesLineFragmentOrigin attributes:attributes context:nil].size; 
    retsize.height =ceilf(retsize.height); 
    retsize.width =ceilf(retsize.width); 

    NSLog(@"%f",retsize.width); 


}else{ 

    if ([text respondsToSelector:@selector(sizeWithFont:constrainedToSize:lineBreakMode:)]){ 
     retsize = [text sizeWithFont:font 
        constrainedToSize:ConstSize 
         lineBreakMode:linebreakmode]; 
     retsize = [text boundingRectWithSize:ConstSize options:NSStringDrawingUsesLineFragmentOrigin attributes:nil context:nil].size; 
    } 
} 
//[self viewWillAppear:YES]; 
return retsize; 

}

이 코드를 사용해보십시오.

1.이 코드를 사용하는 경우 레이블에 위쪽, 아래쪽, 왼쪽 및 오른쪽 제한 만 부여해야합니다.

-(CGFloat)tableView:(UITableView *)tableView estimatedHeightForRowAtIndexPath:(NSIndexPath *)indexPath { 
    //Here you give a minimum height of the cell size. 
    return 110; 
} 
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    return UITableViewAutomaticDimension; 
}
