使用OC和Swift完成图片和文字在一起如下图的效果：
demo效果图
OC版本
- (void)viewDidLoad {
[super viewDidLoad];
//属性文本 Attachment - 附件
NSTextAttachment *attachment = [[NSTextAttachment alloc] init];
attachment.image = [UIImage imageNamed:@"d_aini"];
//lineHeight 大致和字体大小相等
CGFloat height = self.label.font.lineHeight;
attachment.bounds = CGRectMake(0, -3, height, height);
NSAttributedString *imageStr = [NSAttributedString attributedStringWithAttachment:attachment];
//定义一个可变的属性字符串
NSMutableAttributedString *attrMStr= [[NSMutableAttributedString alloc] initWithString:@"我"];
//拼接图片文本
[attrMStr appendAttributedString:imageStr];
[attrMStr appendAttributedString:[[NSAttributedString alloc] initWithString:@"爱你"]];
//设置属性文本
self.label.attributedText = attrMStr;
}
Swift版本
@IBOutlet weak var label: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
//创建一个属性文本
//图片附件
let attactment = NSTextAttachment()
attactment.image = #imageLiteral(resourceName: "d_aini")
let imageStr = NSAttributedString(attachment: attactment)
let height = label.font.lineHeight
attactment.bounds = CGRect(x: 0, y: -3, width: height, height: height)
let attrStr = NSAttributedString(string: "我")
let mAttrStr = NSMutableAttributedString(attributedString: attrStr)
mAttrStr.append(imageStr)
mAttrStr.append(NSAttributedString(string: "爱你"))
label.attributedText = mAttrStr
}
