iOS获取其他APP安装列表

iOS中获取其他APP安装状况是分析竞品的重要途径，推荐使用 系统的canopenUrl api，操作简单稳定；
首先需要拿到你想要获取app的Scheme，可以去知乎或其他网站去查阅，添加到你的infoPlist。也就是添加到白名单，然后获取列表；

具体代码如下：
info.plist

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<array>
    <string>tim</string>
    <string>mqqOpensdkSSoLogin</string>
       ...

</array>
</plist>

获取代码：我这里设置了扫描时间是一天一次

#import "BCYInstalledAppTrackManager.h"
#import "BCYFoundation.h"
#import "BCYTrackManager.h"
#import "Constants.h"
#import <UIKit/UIKit.h>

static NSString *const kBCYScanAppTimeKey = @"scan_app_time";
static NSUInteger const kBCYScanAppFrequencyHour = 24;

@implementation BCYInstalledAppTrackManager

+ (void)detectScheme {
    //上一次扫描时间戳
    NSDate *oldTime = (NSDate *)[USER_DEFAULTS objectForKey:kBCYScanAppTimeKey];
    //当前时间戳
    NSTimeInterval hours = -([oldTime timeIntervalSinceNow] / 3600);

    if (oldTime == nil || hours > kBCYScanAppFrequencyHour) {

        // app包名
        NSArray *schemes = @[
            @"iqiyi-acg", @"boodo", @"diyidanApp", @"uxinlive", @"kuaikan", @"comicreader", @"neteasecomic", @"LOFTER",
            @"wbdm-app", @"acfun", @"bilibili", @"baozoumanhua", @"buka", @"u17app", @"dongman"
        ];
        //扫描到的app
        NSMutableString *scaned = [[NSMutableString alloc] init];
        for (NSString *str in schemes) {
            NSString *urlString = [str stringByAppendingString:@"://"];
            if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:urlString]]) {
                NSString *trackString = [str stringByAppendingString:@"|"];
                [scaned appendString:trackString];
            }
        }
        // BDALOG_INFO(@"检测到竞品：%@",scaned);
        NSDictionary *dic = @{@"app_package_list" : scaned};
        //上报时候的时间
        NSDate *now = [NSDate date];
        [USER_DEFAULTS setObject:now forKey:kBCYScanAppTimeKey];
    }
}
