在获取iOS设备上应用运行状态的时候，用下面的代码有问题，求解
/- (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 * processName = [[NSString alloc]initWithUTF8String:process[i].kp_proc.p_comm];
NSLog(@"process[i].kp_proc.p_comm==%s",process[i].kp_proc.p_comm);
NSLog(@"processName==%@",processName);
// 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:processName];
// [dict release];
}
free(process);
return array;
}
}
}
return nil;
}
NSString * processName = [[NSString alloc]initWithUTF8String:process[i].kp_proc.p_comm];
这个的长度是限制在16位以内的，一旦超出16位就会编码错误，processName变成nil，这个怎么改呢？求大神解答
