获取IOS应用列表

获取运行程序列表

int mib[4] = {CTL_KERN, KERN_PROC, KERN_PROC_ALL, 0};
size_t miblen = 4;

size_t size;
int st = sysctl(mib, miblen, NULL, &size, NULL, 0);

struct kinfo_proc * process = NULL;
struct kinfo_proc * newprocess = NULL;

newprocess = realloc(process, size);

if (!newprocess){

if (process){
free(process);

return nil;
}

process = newprocess;

} while (st == -1 && errno == ENOMEM);

if (st == 0){

if (size % sizeof(struct kinfo_proc) == 0){
int nprocess = size / sizeof(struct kinfo_proc);

if (nprocess){

NSMutableArray * array = [[NSMutableArray alloc] init];

for (int i = nprocess - 1; i >= 0; i--){

NSString * processID = [[NSString alloc] initWithFormat:@"%d", process[i].kp_proc.p_pid];
NSString * processName = [[NSString alloc] initWithFormat:@"%s", process[i].kp_proc.p_comm];

NSDictionary * dict = [[NSDictionary alloc] initWithObjects:[NSArray arrayWithObjects:processID, processName, nil]
forKeys:[NSArray arrayWithObjects:@"ProcessID", @"ProcessName", nil]];
[processID release];
[processName release];
[array addObject:dict];
[dict release];
}

free(process);
return [array autorelease];
}
}
}

return nil;

// Example usage.
NSArray * processes = [[UIDevice currentDevice] runningProcesses];
for (NSDictionary * dict in processes){
NSLog(@"%@ - %@", [dict objectForKey:@"ProcessID"], [dict objectForKey:@"ProcessName"]);
}

这种方法是获取运行中的应用列表。如果应用没被运行过或不在后台，就得不到喽。

比起上面两个方法要靠谱一点儿的就是私有API了。

BOOL APCheckIfAppInstalled(NSString *bundleIdentifier){
static NSString *const cacheFileName = @"com.apple.mobile.installation.plist";
NSString *relativeCachePath = [[@"Library" stringByAppendingPathComponent: @"Caches"] stringByAppendingPathComponent: cacheFileName];
NSDictionary *cacheDict = nil;
NSString *path = nil;
NSLog(@"relativeCachePath:%@",relativeCachePath);
// Loop through all possible paths the cache could be in
for (short i = 0; 1; i++)    {
switch (i) {
case 0: // Jailbroken apps will find the cache here; their home directory is /var/mobile
path = [NSHomeDirectory() stringByAppendingPathComponent: relativeCachePath];
break;
case 1: // App Store apps and Simulator will find the cache here; home (/var/mobile/) is 2 directories above sandbox folder
path = [[NSHomeDirectory() stringByAppendingPathComponent: @"../.."] stringByAppendingPathComponent: relativeCachePath];
break;
case 2: // If the app is anywhere else, default to hardcoded /var/mobile/
path = [@"/var/mobile" stringByAppendingPathComponent: relativeCachePath];
break;
default: // Cache not found (loop not broken)
return NO;
break;
}
BOOL isDir = NO;
NSLog(@"path:%@",path);
// Ensure that file exists
if ([[NSFileManager defaultManager] fileExistsAtPath:path isDirectory:&isDir] && !isDir){
cacheDict = [NSDictionary dictionaryWithContentsOfFile: path];
}

// If cache is loaded, then break the loop. If the loop is not "broken," it will return NO later (default: case)
if (cacheDict){
NSLog(@"cacheDict:%@",cacheDict);
break;
}

}

NSLog(@"gggg");
// First check all system (jailbroken) apps
NSDictionary *system = [cacheDict objectForKey: @"System"];
NSLog(@"system:%@",system);
if ([system objectForKey: bundleIdentifier]){
return YES;
}

// Then all the user (App Store /var/mobile/Applications) apps
NSDictionary *user = [cacheDict objectForKey: @"User"];
NSLog(@"user:%@",user);
if ([user objectForKey: bundleIdentifier]){
return YES;
}

// If nothing returned YES already, we'll return NO now
return NO;
}

不过这种方法需要机器已经越狱，还需要你的应用不在沙盒里，由于后一条笔者还不大会搞，所以没试成功:)
