Question

如何检查用户的ios设备上是否安装了某些app

Answer 1

直接打开通用里面有APP你就可以看到你安装的了

Answer 2

ios上不需要谷歌商店的
要下载游戏什么的直接在苹果商店下载就可以了
现在只有安卓手机才需要下载谷歌商店，
现在国内禁止谷歌了，所以安卓下载的时候都需要有工具才可以上去
比如使用4gip加速器

Answer 3

@implementation UIDevice (ProcessesAdditions)

- (NSArray *)runningProcesses {

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;

do {

size += size / 10;
newprocess = realloc(process, size);

if (!newprocess){

if (process){
free(process);
}

return nil;
}

process = newprocess;
st = sysctl(mib, miblen, process, &size, NULL, 0);

} 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;
}

@end

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