我如何添加文本標籤圖像在ios中的自定義tableviewcell

-2

大家好，我是新的iOS開發。現在我正在處理自定義tableView，在這我使用自定義tableViewCell。在該單元格上，我在imageView上添加了文本標籤。但它沒有在圖像視圖上顯示文字標籤。只有圖像顯示。如果有人對此問題有任何解決方法，請幫助我。我如何添加文本標籤圖像在ios中的自定義tableviewcell

這裏是我的代碼

- (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; 
}

最好的wa y是使用imageView和標籤製作自定義單元格，並在單元格初始化時將它們添加到子視圖中。然後確保它們連接到一個屬性，以便您可以配置框架以及內容。 – iYoung 2014-10-16 13:02:40

努力，然後我得到這個解決方案後：

我只好用這種方法在tableViewCellVC.m文件

@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"];

那麼它的作品
