问题描述
RT 我实现出来了，但是，在ios 10上面有问题。
NSString *text = [label text];UIFont *font = [label font];CGRect rect = [label frame];CTFontRef myFont = CTFontCreateWithName((__bridge CFStringRef)([font fontName]), [font pointSize], NULL);NSMutableAttributedString *attStr = [[NSMutableAttributedString alloc] initWithString:text];[attStr addAttribute:(NSString *)kCTFontAttributeName value:(__bridge id)myFont range:NSMakeRange(0, attStr.length)];CTFramesetterRef frameSetter = CTFramesetterCreateWithAttributedString((__bridge CFAttributedStringRef)attStr);CGMutablePathRef path = CGPathCreateMutable();CGPathAddRect(path, NULL, CGRectMake(0,0,rect.size.width,100000));CTFrameRef frame = CTFramesetterCreateFrame(frameSetter, CFRangeMake(0, 0), path, NULL);NSArray *lines = (__bridge NSArray *)CTFrameGetLines(frame);NSMutableArray *linesArray = [[NSMutableArray alloc]init];//获取到每一行数组for (id line in lines){ CTLineRef lineRef = (__bridge CTLineRef )line; CFRange lineRange = CTLineGetStringRange(lineRef); NSRange range = NSMakeRange(lineRange.location, lineRange.length);NSString *lineString = [text substringWithRange:range]; [linesArray addObject:lineString];}
但是这样在ios 10上面有问题，跪求大神
