 @interface BWApp : NSObject

 @property (nonatomic, copy) NSString *size;
 @property (nonatomic, copy) NSString *download;
 @property (nonatomic, copy) NSString *name;
 @property (nonatomic, copy) NSString *icon;
 //标记是否被下载过
 @property (nonatomic, assign) BOOL isDownloaded;

 #import "BWApp.h"

 @implementation BWApp

 - (instancetype)initWithDict:(NSDictionary *)dict
 {
     if (self = [super init]) {
         [self setValuesForKeysWithDictionary:dict];
     }
     return self;
 }

 + (instancetype)appWithDict:(NSDictionary *)dict
 {
     return [[self alloc] initWithDict:dict];
 }

 @end

二、View

 #import <UIKit/UIKit.h>
 @class BWAppCell;
 @protocol appCellDelegate <NSObject>

 - (void)btnDownloadClick:(BWAppCell *)appCell;

 @end

 @class BWApp;
 @interface BWAppCell : UITableViewCell

 @property (nonatomic, strong) BWApp *app;
 @property (nonatomic, strong) id<appCellDelegate> delegate;

 @end

 //

 #import "BWAppCell.h"
 #import "BWApp.h"

 @interface BWAppCell ()
 @property (weak, nonatomic) IBOutlet UIImageView *appIcon;
 @property (weak, nonatomic) IBOutlet UILabel *appName;
 @property (weak, nonatomic) IBOutlet UILabel *appDesc;

 @property (weak, nonatomic) IBOutlet UIButton *appDownload;
 - (IBAction)appDownload:(id)sender;

 @end

 @implementation BWAppCell

 - (void)setApp:(BWApp *)app
 {
     _app = app;

     //给子控件设置数据
     self.appIcon.image = [UIImage imageNamed:_app.icon];
     self.appName.text = _app.name;
     self.appDesc.text = [NSString stringWithFormat:@"大小：%@ | 下载量：%@",_app.size,_app.download];

     //更新下载按钮状态
     if (app.isDownloaded) {
         self.appDownload.enabled = NO;
     }
     else
         self.appDownload.enabled = YES;

 }

 #pragma mark - 下载按钮点击事件
 - (IBAction)appDownload:(id)sender {
     //1.禁用按钮
     self.appDownload.enabled = NO;
     //已经被点击过了
     self.app.isDownloaded = YES;
     if ([self.delegate respondsToSelector:@selector(btnDownloadClick:)]) {
         [self.delegate btnDownloadClick:self];
     }
 }

 - (void)awakeFromNib {
     // Initialization code
 }

 - (void)setSelected:(BOOL)selected animated:(BOOL)animated {
     [super setSelected:selected animated:animated];

     // Configure the view for the selected state
 }

 @end

三、Controller

 @interface ViewController ()<appCellDelegate>

 @property (nonatomic, strong) NSArray *appArray;

 @end

 @implementation ViewController

 #pragma mark - appCellDelegate代理方法
 - (void)btnDownloadClick:(BWAppCell *)appCell

     //1.创建一个Label
     UILabel *lblMsg = [[UILabel alloc] initWithFrame:CGRectMake(, (self.view.frame.size.height - )/, , )];
     lblMsg.text = @"正在下载...";
     lblMsg.textAlignment = NSTextAlignmentCenter;
     lblMsg.backgroundColor = [UIColor blackColor];
     lblMsg.textColor = [UIColor redColor];
     //设置透明度
     lblMsg.alpha = 0.0;
     //设置圆角
     lblMsg.layer.cornerRadius = ;
     lblMsg.layer.masksToBounds = YES;
     //[self.view addSubview:lblMsg];

     [[[UIApplication sharedApplication] keyWindow] addSubview:lblMsg];

     //动画方式显示Label
 //    [UIView animateWithDuration:1.0 animations:^{

     } completion:^(BOOL finished) {

 }

 #pragma mark - 懒加载
