iOS NSTextAttachment富文本

实现一段文字中,插入一个一张图片

+(NSAttributedString*)getString:(NSString*)string pictureName:(UIImage*)imageName textFount:(CGFloat)FountSize pictureSize:(CGRect)pictureRect

{

// NSTextAttach可以将图片转换为富文本内容

NSTextAttachment*attachment = [[NSTextAttachmentalloc]init];

//创建通过NSTextAttachment的富文本

//图片的富文本

attachment.image= imageName;

//文字的富文本

NSAttributedString*imageAttr = [NSAttributedStringattributedStringWithAttachment:attachment];

NSAttributedString*textAttr = [[NSAttributedStringalloc]initWithString:stringattributes:@{NSFontAttributeName: [UIFontsystemFontOfSize:FountSize]}];

NSMutableAttributedString*mutableAttr = [[NSMutableAttributedStringalloc]init];

[mutableAttrappendAttributedString:textAttr];

[mutableAttrappendAttributedString:imageAttr];

return[mutableAttrcopy];

}
