自定义Lable设置Lable与文字长度,两个字符串拼接

.h

#import <UIKit/UIKit.h>

@interface DetailLable : UILabel

-(void)setText:(NSString *)titleText title:(NSString *)text setFram:(CGRect)frame;

@end

.m

#import "DetailLable.h"
#define cellpading 8
@implementation DetailLable

-(void)setText:(NSString *)titleText title:(NSString *)text setFram:(CGRect)frame
{
    self.textColor = [UIColor blackColor];
    self.font = [UIFont fontWithName: @"Helvetica-Bold" size : 17.0 ];
    float sizex = frame.origin.x;
    float sizey = frame.origin.y;
    NSString *theText =  [titleText stringByAppendingFormat:@"%@",text];;
    CGSize theStringSize = [theText sizeWithFont:self.font
                               constrainedToSize:self.frame.size
                                   lineBreakMode:self.lineBreakMode];

    //Adjust the size of the UILable
    self.frame = CGRectMake(sizex,
                                sizey+cellpading,
                                theStringSize.width, theStringSize.height);
    self.text = theText;

}

实现

DetailLable *imageStyleMuchNow = [[DetailLable alloc] init];
    [imageStyleMuchNow setText:@"899.0" title:@"元" setFram:CGRectMake(10, imageView.frame.origin.y+imageView.frame.size.height,40,20)];
    imageStyleMuchNow.textColor = [UIColor blueColor];
    [scrollView addSubview:imageStyleMuchNow];
