图文混排之简单运用

最近对图文混排的技术点做了点研究，希望能帮助开发中遇到困难的人！废话不多说直接看效果图

核心代码：

-(void)setModel:(ZHModel *)model{

_model = model;

NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:model.text];

if (![model.icon isEqualToString:@"123"]) {

NSAttributedString *str1 = [[NSAttributedString alloc] initWithString:@"\t"];

[str insertAttributedString:str1 atIndex:0];

NSMutableParagraphStyle *pr = [[NSMutableParagraphStyle alloc] init];

pr.lineBreakMode = NSLineBreakByTruncatingTail;

pr.alignment = NSTextAlignmentLeft;

pr.lineSpacing = 3;

pr.paragraphSpacing = 0;

NSDictionary

*dict = @{NSFontAttributeName:[UIFont systemFontOfSize:14

weight:8],NSForegroundColorAttributeName:[UIColor

greenColor],NSParagraphStyleAttributeName:pr};

[str setAttributes:dict range:NSMakeRange(0, str.length)];

NSAttributedString *str2 = [[NSAttributedString alloc] initWithString:@"\n\t"];

[str appendAttributedString:str2];

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

att.image = [UIImage imageNamed:model.icon];

att.bounds = CGRectMake(0, 0, 300, 80);

[str appendAttributedString:[NSAttributedString attributedStringWithAttachment:att]];

self.label1.attributedText = str;

}else{

NSMutableParagraphStyle *pr = [[NSMutableParagraphStyle alloc] init];

pr.lineBreakMode = NSLineBreakByTruncatingTail;

pr.alignment = NSTextAlignmentCenter;

pr.lineSpacing = 3;

pr.paragraphSpacing = 0;

NSDictionary

*dict = @{NSFontAttributeName:[UIFont systemFontOfSize:14

weight:8],NSForegroundColorAttributeName:[UIColor

greenColor],NSParagraphStyleAttributeName:pr};

[str setAttributes:dict range:NSMakeRange(0, str.length)];

self.label1.attributedText = str;

}

}
