.h文件

#import <UIKit/UIKit.h>

@interface UILabel (HCL)

+ (CGFloat)getWidthWithTitle:(NSString *)title font:(UIFont *)font;

.m文件

#import "UILabel+HCL.h"

@implementation UILabel (HCL)
+ (CGFloat)getHeightByWidth:(CGFloat)width title:(NSString *)title font:(UIFont *)font
{
    
    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, width, 0)];
    label.text = title;
    label.font = font;
    label.numberOfLines = 0;
    [label sizeToFit];
    CGFloat height = label.frame.size.height;
    return height;
}

+ (CGFloat)getWidthWithTitle:(NSString *)title font:(UIFont *)font {
    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 1000, 0)];
    label.text = title;
    label.font = font;
    [label sizeToFit];
    return label.frame.size.width;
}
@end

使用方法:

//文字label
    UILabel* bodyLabel = [[UILabel alloc]initWithFrame: CGRectMake(2, 60, self.frame.size.width, 20)];
    bodyLabel.text = dic[@"text"];
        NSLog(@"%@",dic[@"text"]);
    bodyLabel.numberOfLines = 0;
    bodyLabel.font = [UIFont systemFontOfSize:14];
    CGFloat hight = [UILabel getHeightByWidth:bodyLabel.frame.size.width title:bodyLabel.text font:bodyLabel.font];
//适应宽度
// CGFloat width = [UILabel getWidthWithTitle:bodyLabel.text font:bodyLabel.font];
//bodyLabel.frame = CGRectMake(2, 60, width, 100);
    bodyLabel.frame = CGRectMake(2, 60, self.frame.size.width, hight);
    
    [self addSubview:bodyLabel];
