越狱状态下获取设备上已安装的app和icon

目前获取已安装app的方法主要有以下几种：

1.通过com.apple.mobile.installation.plist文件获取；

2.通过MobileInstallation.framework获取；

3.通过LSApplicationWorkspace：

#include <objc/runtime.h>Class LSApplicationWorkspace_class = objc_getClass("LSApplicationWorkspace");NSObject* workspace = [LSApplicationWorkspace_class performSelector:@selector(defaultWorkspace)];NSLog(@"apps: %@", [workspace performSelector:@selector(allApplications)]);

这种方法可以在非越狱情况下使用，但只能获取应用的bundle ID，无法获取中文名称和icon。

我采用的则是最暴力最直接的方法：递归遍历Applications路径下所有app的plist：

- (void)scanApps{    NSString *pathOfApplications;    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)        pathOfApplications = @"/var/mobile/Containers/Bundle/Application";    else        pathOfApplications = @"/var/mobile/Applications";        NSLog(@"scan begin");        // all applications    NSArray *arrayOfApplications = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:pathOfApplications error:nil];        for (NSString *applicationDir in arrayOfApplications) {        // path of an application        NSString *pathOfApplication = [pathOfApplications stringByAppendingPathComponent:applicationDir];        NSArray *arrayOfSubApplication = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:pathOfApplication error:nil];        // seek for *.app        for (NSString *applicationSubDir in arrayOfSubApplication) {            if ([applicationSubDir hasSuffix:@".app"]) {// *.app                NSString *path = [pathOfApplication stringByAppendingPathComponent:applicationSubDir];                NSString *imagePath = [pathOfApplication stringByAppendingPathComponent:applicationSubDir];                path = [path stringByAppendingPathComponent:@"Info.plist"];                // so you get the Info.plist in the dict                NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:path];                if([[dict allKeys] containsObject:@"CFBundleIdentifier"] && [[dict allKeys] containsObject:@"CFBundleDisplayName"]){                    NSArray *values = [dict allValues];        <span style="white-space:pre"></span>    NSString *icon;        <span style="white-space:pre"></span>    for (int i = 0; i < values.count; i++) {           <span style="white-space:pre"></span> icon = [self getIcon:[values objectAtIndex:i] withPath:imagePath];           <span style="white-space:pre"></span> if (![icon isEqualToString:@""]) {                      }                <span style="white-space:pre"></span>     imagePath = [imagePath stringByAppendingPathComponent:icon];            <span style="white-space:pre"></span>     break;           <span style="white-space:pre"></span> }       <span style="white-space:pre"></span>    }                }            }        }    }}

- (NSString *)getIcon:(id)value withPath:(NSString *)imagePath{    if([value isKindOfClass:[NSString class]]) {        NSRange range = [value rangeOfString:@"png"];        NSRange iconRange = [value rangeOfString:@"icon"];        NSRange IconRange = [value rangeOfString:@"Icon"];        if (range.length > 0){            NSString *path = [imagePath stringByAppendingPathComponent:value];            UIImage *image = [UIImage imageWithContentsOfFile:path];            if (image != nil && image.size.width > 50 && image.size.height > 50) {                return value;            }        }        else if(iconRange.length > 0){            NSString *imgUrl = [NSString stringWithFormat:@"%@.png",value];            NSString *path = [imagePath stringByAppendingPathComponent:imgurl];            UIImage *image = [UIImage imageWithContentsOfFile:path];            if (image != nil && image.size.width > 50 && image.size.height > 50) {                return imgUrl<span style="font-family: Arial, Helvetica, sans-serif;">;</span>            }        }        else if(IconRange.length > 0){            NSString *imgUrl = [NSString stringWithFormat:@"%@.png",value];            NSString *path = [imagePath stringByAppendingPathComponent:imgurl];            UIImage *image = [UIImage imageWithContentsOfFile:path];            if (image != nil && image.size.width > 50 && image.size.height > 50) {                return imgUrl;            }        }    }    else if([value isKindOfClass:[NSDictionary class]]){        NSDictionary *dict = (NSDictionary *)value;        for (id subValue in [dict allValues]) {            NSString *str = [self getIcon:subValue withPath:imagePath];            if (![str isEqualToString:@""]) {                return str;            }        }    }    else if([value isKindOfClass:[NSArray class]]){        for (id subValue in value) {            NSString *str = [self getIcon:subValue withPath:imagePath];            if (![str isEqualToString:@""]) {                return str;            }        }    }    return @"";}
