iOS-图文混排方案-2种方案

ios的图文混排有两种方案
1.使用NSTextAttachment

- (NSMutableAttributedString*)createTextImage:(NSString*)text witImage:(NSString*)imageName{
    NSMutableAttributedString *scaleStr=  [[NSMutableAttributedString alloc] initWithString:text attributes:@{NSForegroundColorAttributeName:[UIColor whiteColor], NSFontAttributeName:PingFangBold(18)}];
   //添加图片
    NSTextAttachment *textAttachment = [[NSTextAttachment alloc] init];
    textAttachment.bounds = CGRectMake(0, 2, 12, 7); //根据图片位置进行调整
    textAttachment.image = [UIImage imageNamed:imageName];
    NSAttributedString *attributedImage = [NSAttributedString attributedStringWithAttachment:(NSTextAttachment *)(textAttachment)];
   //图片插入到文字后方
    [scaleStr appendAttributedString:attributedImage];
   //如果要插入到前面
  // [scaleStr insertAttributedString:attributedImage atIndex:0];
    return scaleStr;
}

2.使用YYText库，这个扩展性更好,如果做直播的话，可以用在聊天窗口，可以添加UIKit的控件，可以添加事件

- (YYTextLayout *)createTextImage:(NSString*)text witImage:(NSString*)imageName withSize:(CGSize)finalSize{
    UIFont *font = [UIFont systemFontOfSize:14];
    NSMutableAttributedString *textGold = [[NSMutableAttributedString alloc] initWithString:text attributes:@{NSForegroundColorAttributeName:[UIColor blackColor], NSFontAttributeName:font}];
  //可以添加UIKit的控件及事件
    UIImageView *imagImage = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 50, 50)];
    NSMutableAttributedString *attachTextRecahrage = [NSMutableAttributedString yy_attachmentStringWithContent:imagImage contentMode:UIViewContentModeLeft attachmentSize:CGSizeMake(62, 22) alignToFont:font alignment:YYTextVerticalAlignmentCenter];
    [textGold  appendAttributedString:attachTextRecahrage];
    //如果要插入到前面
//    [textGold insertAttributedString:attachTextRecahrage atIndex:0];
    YYTextContainer *container = [YYTextContainer containerWithSize:CGSizeMake(finalSize.width, finalSize.height)]; //图文混排需要的宽度及高度
    YYTextLayout *textLayout = [YYTextLayout layoutWithContainer:container text:textGold];
    return textLayout;
}

//使用
    YYLabel *labeShow = [[YYLabel alloc] initWithFrame:CGRectMake(0, 0,100, 50)];
    labeShow.textColor = [UIColor blackColor];
    labeShow.textLayout = [self createTextImage:@"文字" witImage:@"图片" withSize:labeShow.size];
    labeShow.textAlignment = NSTextAlignmentLeft;
    [self.view addSubview:labeShow];
