获取当前下载的app及下载进度

涉及到的两个.h LSApplicationWorkspace 扫描系统中所有app的状态 LSApplicationProxy 应用下载进度

#import <dlfcn.h>
#import "LSApplicationProxy.h"
#import "LSApplicationWorkspace.h"
-(void)updateInstallList

NSString* bundleId =[LSApplicationProxy applicationIdentifier];
//获取app安装进度
NSProgress *progress = (NSProgress *)[LSApplicationProxy installProgress];

//根据下载进度 查看是否是正在下载
if (progress)

}
-(InstallingModel *)getInstallModel:(NSString *)bunldID
