将图像附加到UILabel无法正常工作

Question

我想在iOS中向UILabel添加正确的小图标

这是我正在使用的代码

NSTextAttachment *attachment = [[NSTextAttachment alloc] init];
        attachment.image = [UIImage imageNamed:@"icon_list"];

        NSAttributedString *attachmentString = [NSAttributedString attributedStringWithAttachment:attachment];

        NSMutableAttributedString *myString= [[NSMutableAttributedString alloc] initWithString:@"Hi"];
        [myString appendAttributedString:attachmentString];

        cell.categoryTitle.attributedText = myString;

我得到的结果如下，字符串和三个点，任何人都可以告诉我这是什么问题？

Answer 1

问题是图标大小非常大，我通过调整图标大小来解决它，然后再添加到我的标签

所以工作代码如下：

UIImage *image1 = [UIImage imageNamed:@"icon_ads.png”];

UIImage *myIcon = [self imageWithImage:image1 scaledToSize:CGSizeMake(20, 20)];

NSTextAttachment *attachment = [[NSTextAttachment alloc] init];

attachment.image = myIcon;

NSAttributedString *attachmentString = [NSAttributedString attributedStringWithAttachment:attachment];

NSAttributedString *titleString = [[NSAttributedString alloc] initWithString:test.catName];

NSMutableAttributedString *myString = [[NSMutableAttributedString alloc] initWithString:@""];

[myString appendAttributedString:attachmentString];

[myString appendAttributedString:titleString];

cell.categoryTitle.attributedText = myString;
