어떻게 iOS의 사용자 정의 tableviewcell에 이미지에 텍스트 레이블을 추가 할 수 있습니까?

Question

안녕하세요 여러분, 저는 iOS 개발에 새로운입니다. 이제 맞춤 tableView에서 작업하고 있습니다.이 작업은 맞춤 tableViewCell을 사용하고 있습니다. 해당 셀에 imageView에 텍스트 레이블을 추가합니다. 하지만 이미지 뷰에 텍스트 레이블을 표시하지 않습니다. 이미지 만 보여줍니다. 누군가이 문제에 대한 해결책이 있다면 저를 도우십시오. 여기

내가이 솔루션을 가지고 다음 열심히 노력하면 내 코드

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    static NSString *CellIdentifier = @"MyCell"; 
    ItemsCellVC *cell = (ItemsCellVC *)[TableView dequeueReusableCellWithIdentifier:CellIdentifier]; 

    if (cell == nil) { 
     cell = [[ItemsCellVC alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; 


    } 

    UIImage *background = [self cellBackgroundForRowAtIndexPath:indexPath]; 
    UIImageView *cellBackgroundView = [[UIImageView alloc] initWithImage:background]; 
    cellBackgroundView.image = background; 
    cell.backgroundView = cellBackgroundView; 





    if ([arrayForItemDictionary count]!=0) { 

    if (tableView == aSearchDisplayController.searchResultsTableView) 
     { 
     dictItemFromDatabase=[filteredListContent objectAtIndex:indexPath.row]; 
     } 
    else 
     { 
     dictItemFromDatabase=[arrayForItemDictionary objectAtIndex:indexPath.row]; 
     } 

    } 




    //cell.containerNameLabel.text=[dictItemFromDatabase valueForKey:@"PickerName"]; 
    cell.itemNameLabel.text = [dictItemFromDatabase valueForKey:@"ItemNameTF"]; 
    cell.containerImgView.image = [UIImage imageNamed:@"12-02 (1)"]; 

    UIImage *image = [UIImage imageNamed:@"2-02 (1).png"]; 

    cell.containerImgView.image = [self addText:image text:@"Hello there"]; 



    return cell; 
} 


-(UIImage *)addText:(UIImage *)img text:(NSString *)text1{ 

    int w = img.size.width; 
    int h = img.size.height; 
    CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); 
    CGContextRef context = CGBitmapContextCreate(NULL, w, h, 8, 4 * w, colorSpace, kCGImageAlphaPremultipliedFirst); 
    CGContextDrawImage(context, CGRectMake(0, 0, w, h), img.CGImage); 

    char* text= (char *)[text1 cStringUsingEncoding:NSASCIIStringEncoding]; 
    CGContextSelectFont(context, "Arial",20, kCGEncodingMacRoman); 
    CGContextSetTextDrawingMode(context, kCGTextFill); 
    CGContextSetRGBFillColor(context, 0, 0, 0, 1); 
    CGContextShowTextAtPoint(context,10,10,text, strlen(text)); 
    CGImageRef imgCombined = CGBitmapContextCreateImage(context); 

    CGContextRelease(context); 
    CGColorSpaceRelease(colorSpace); 

    UIImage *retImage = [UIImage imageWithCGImage:imgCombined]; 
    CGImageRelease(imgCombined); 

    return retImage; 
}

입니다 : tableViewCellVC.m에서이 방법은

@implementation UIImage (DrawWatermarkText) 
-(UIImage*)drawWatermarkText:(NSString*)text { 
UIColor *textColor = [UIColor grayColor];//[UIColor colorWithWhite:0 alpha:0.1]; 
UIFont *font = [UIFont systemFontOfSize:400]; 
// CGFloat paddingX = 50.f; 
CGFloat paddingY = 200.f; 

// Compute rect to draw the text inside 
CGSize imageSize = self.size; 
NSDictionary *attr = @{NSForegroundColorAttributeName: textColor, NSFontAttributeName: font}; 
CGSize textSize = [text sizeWithAttributes:attr]; 

// CGRect textRect = CGRectMake(imageSize.width - textSize.width - paddingX, imageSize.height - textSize.height - paddingY-50, textSize.width, textSize.height); 

CGRect textRect = CGRectMake(imageSize.width - 1900, imageSize.height - textSize.height - paddingY, textSize.width, textSize.height); 

// Create the image 
UIGraphicsBeginImageContext(imageSize); 
[self drawInRect:CGRectMake(0, 0, imageSize.width, imageSize.height)]; 
[text drawInRect:CGRectIntegral(textRect) withAttributes:attr]; 
UIImage *resultImage = UIGraphicsGetImageFromCurrentImageContext(); 
UIGraphicsEndImageContext(); 
return resultImage;}@end 

later on i had write following code in tableViewCellVC.h file as 

@interface UIImage (DrawWatermarkText) 
-(UIImage*)drawWatermarkText:(NSString*)text; 
    @end 
And Finally in cellforRowAtIndexPath in tavelVC.m call this method only 

UIImage *image = [UIImage imageNamed:@"12-02 (1)"]; 

cell.containerImgView.image = [image drawWatermarkText:@"Bharat"];
