根据你的代码我帮你重新调整了一下，你可以参考如下代码哦：
// DiyCoinView.h #import <UIKit/UIKit.h> #import "CustomModel.h" @interface DiyCoinView : UIView @property(nonatomic,weak) UIImageView *coinImageView; @property(nonatomic,weak) UILabel *money; @property (nonatomic, strong) CustomModel *model; @end // DiyCoinView.m #import "DiyCoinView.h" #import "CustomModel.h" @implementation DiyCoinView -(instancetype)initWithFrame:(CGRect)frame{ if(self=[super initWithFrame:frame]){ UIImageView *coinImageView = [[UIImageView alloc]init]; self.coinImageView = coinImageView; [self addSubview:coinImageView]; UILabel *money = [[UILabel alloc]init]; money.textAlignment = NSTextAlignmentCenter; self.money = money; [self addSubview:money]; } return self; } -(void)layoutSubviews{ [super layoutSubviews]; CGFloat coinImageViewX = self.frame.origin.x; CGFloat coinImageViewY = self.frame.origin.y; CGFloat coinImageViewW = 30; CGFloat coinImageViewH = self.frame.size.height; self.coinImageView.frame = CGRectMake(coinImageViewX, coinImageViewY, coinImageViewW, coinImageViewH); CGFloat moneyLabelX = self.frame.origin.x+40; CGFloat moneyLabelY = self.frame.origin.y; CGFloat moneyLabelW = self.frame.size.width-40; CGFloat moneyLabelH = self.frame.size.height; self.money.frame = CGRectMake(moneyLabelX, moneyLabelY, moneyLabelW, moneyLabelH); } - (void)setModel:(CustomModel *)model { _model = model; self.coinImageView.image = [UIImage imageNamed:model.icon]; self.money.text = model.name; } @end // CustomModel.h #import <Foundation/Foundation.h> @interface CustomModel : NSObject /** * 金钱 */ @property (nonatomic, copy) NSString *name; /** * 图片 */ @property (nonatomic, copy) NSString *icon; + (instancetype)modelWithName:(NSString *)name icon:(NSString *)icon; - (instancetype)initWithName:(NSString *)name icon:(NSString *)icon; @end // CustomModel.m #import "CustomModel.h" @implementation CustomModel + (instancetype)modelWithName:(NSString *)name icon:(NSString *)icon { return [[self alloc] initWithName:name icon:icon]; } - (instancetype)initWithName:(NSString *)name icon:(NSString *)icon { if (self = [super init]) { self.name = name; self.icon = icon; } return self; } @end // ViewController.m #import "ViewController.h" #import "DiyCoinView.h" #import "CustomModel.h" @interface ViewController () @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. [self addUpView]; //[self addcoinView]; } -(void)addUpView{ // 创建自定义的View DiyCoinView *customView = [[DiyCoinView alloc] init]; // 设置数据 CustomModel *model = [CustomModel modelWithName:@"hosea_zhou" icon:@"1"]; customView.model = model; // 设置frame customView.frame = CGRectMake(100, 100, 100, 100); // 添加子控件 [self.view addSubview:customView]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } @end上述就是实现的代码哦，位置我没有仔细给你调整，你可以自己再设置一个比较好的位置，调整一下就好。如果还有什么不明白的地方，可以在问答里继续提问，老师都会帮助解决。祝学习愉快~
