Шаг 1: Создать объект, унаследованный от UIView
Шаг 2: Переопределить - (void) drawRect: (CGRect) метод прямоугольника
Шаг 3: Добавить следующий код к этому методу
/* Define some defaults */
float padding = 10.0f;
/* Get the graphics context for drawing */
CGContextRef ctx = UIGraphicsGetCurrentContext();
/* Core Text Coordinate System is OSX style */
CGContextSetTextMatrix(ctx, CGAffineTransformIdentity);
CGContextTranslateCTM(ctx, 0, self.bounds.size.height);
CGContextScaleCTM(ctx, 1.0, -1.0);
CGRect textRect = CGRectMake(padding, padding, self.frame.size.width - padding*2, self.frame.size.height - padding*2);
/* Create a path to draw in and add our text path */
CGMutablePathRef pathToRenderIn = CGPathCreateMutable();
CGPathAddRect(pathToRenderIn, NULL, textRect);
/* Add a image path to clip around, region where you want to place image */
CGRect clipRect = CGRectMake(padding, self.frame.size.height-50, 50, 40);
CGPathAddRect(pathToRenderIn, NULL, clipRect);
/* Build up an attributed string with the correct font */
NSMutableAttributedString *attrString = [[NSMutableAttributedString alloc] initWithString:self.Text];
//setFont
CTFontRef font = CTFontCreateWithName((CFStringRef) [UIFont systemFontOfSize:10].fontName, [UIFont systemFontOfSize:10].lineHeight, NULL);
CFAttributedStringSetAttribute(( CFMutableAttributedStringRef) attrString, CFRangeMake(0, attrString.length), kCTFontAttributeName,font);
//set text color
CGColorRef _white=[UIColor whiteColor].CGColor;
CFAttributedStringSetAttribute(( CFMutableAttributedStringRef)(attrString), CFRangeMake(0, attrString.length),kCTForegroundColorAttributeName, _white);
/* Get a framesetter to draw the actual text */
CTFramesetterRef fs = CTFramesetterCreateWithAttributedString(( CFAttributedStringRef) attrString);
CTFrameRef frame = CTFramesetterCreateFrame(fs, CFRangeMake(0, attrString.length), pathToRenderIn, NULL);
/* Draw the text */
CTFrameDraw(frame, ctx);
/* Release the stuff we used */
CFRelease(frame);
CFRelease(pathToRenderIn);
CFRelease(fs);
Шаг 4: использовать следующим образом:
TextLayoutView *TextWrappingImage=[[TextLayoutView alloc] init...your own constructor...];
TextWrappingImage.backgroundColor=[UIColor clearColor];
[cell addSubview:TextWrappingImage]; //Add as subview where you want
