@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

#import "BWAppCell.h"
@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(140, (self.view.frame.size.height - 37)/2, 95, 37)];
    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 = 10;
    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:^{
//        lblMsg.alpha = 0.6;
//    }];
    
    [UIView animateWithDuration:1.0 animations:^{
        lblMsg.alpha = 0.6;
    } completion:^(BOOL finished) {
        //动画执行完毕以后
        //再开启一个新动画
        [UIView animateWithDuration:1.0 delay:0.5 options:UIViewAnimationOptionCurveLinear animations:^{
            lblMsg.alpha = 0;
        } completion:^(BOOL finished) {
            [lblMsg removeFromSuperview];
        }];
    }];
}

#pragma mark - 懒加载
