iOS 获取正在运行的进程

转载原址：http://www.jianshu.com/p/ec27662c1557

代码如下：

// .h
@interfaceUIDevice (ProcessesAdditions)

- (NSArray*)runningProcesses;

@end

// .m
#import"UIDevice+ProcessesAdditions.h"

@implementationUIDevice (ProcessesAdditions)
- (NSArray*)runningProcesses {
<span style="white-space:pre">	</span>intmib[4] = {CTL_KERN,KERN_PROC,KERN_PROC_ALL, 0};
<span style="white-space:pre">	</span>intmiblen = 4;
<span style="white-space:pre">	</span>size_tsize;
<span style="white-space:pre">	</span>intst =sysctl(mib, miblen,NULL, &size,NULL, 0);
<span style="white-space:pre">	</span>structkinfo_proc* process =NULL;
<span style="white-space:pre">	</span>structkinfo_proc* newprocess =NULL;
<span style="white-space:pre">	</span>do{
<span style="white-space:pre">		</span>size += size / 10;
<span style="white-space:pre">		</span>newprocess =realloc(process, size);
<span style="white-space:pre">		</span>if(!newprocess){
<span style="white-space:pre">			</span>if(process){
<span style="white-space:pre">				</span>free(process);
<span style="white-space:pre">			</span>}
<span style="white-space:pre">			</span>return nil;
<span style="white-space:pre">		</span>}
<span style="white-space:pre">	</span>process = newprocess;
<span style="white-space:pre">	</span>st =sysctl(mib, miblen, process, &size,NULL, 0);
<span style="white-space:pre">	</span>}while(st == -1 &&errno==ENOMEM);
<span style="white-space:pre">	</span>if(st == 0){
<span style="white-space:pre">		</span>if(size %sizeof(structkinfo_proc) == 0){
<span style="white-space:pre">			</span>longnprocess = size/sizeof(structkinfo_proc);
<span style="white-space:pre">			</span>if(nprocess){
<span style="white-space:pre">				</span>NSMutableArray* array = [[NSMutableArrayalloc]init];
<span style="white-space:pre">				</span>for(longi = nprocess - 1; i >= 0; i--){
<span style="white-space:pre">					</span>NSString* processID = [[NSStringalloc]initWithFormat:@"%d", process[i].kp_proc.p_pid];
<span style="white-space:pre">					</span>NSString* processName = [[NSStringalloc]initWithFormat:@"%s", process[i].kp_proc.p_comm];
<span style="white-space:pre">					</span>NSDictionary* dict = [[NSDictionaryalloc]initWithObjects:[NSArrayarrayWithObjects:processID, processName,nil] forKeys:[NSArrayarrayWithObjects:@"ProcessID",@"ProcessName",nil]];
<span style="white-space:pre">					</span>[processIDrelease];
<span style="white-space:pre">					</span>[processNamerelease];
<span style="white-space:pre">					</span>[arrayaddObject:dict];
<span style="white-space:pre">					</span>[dictrelease];
<span style="white-space:pre">				</span>}
<span style="white-space:pre">				</span>free(process);
<span style="white-space:pre">				</span>return [arrayautorelease];
<span style="white-space:pre">			</span>}
<span style="white-space:pre">		</span>}
<span style="white-space:pre">	</span>}
<span style="white-space:pre">	</span>return nil;
}
@end

如何使用呢？

NSArray* processes = [[UIDevice currentDevice] runningProcesses];
for(NSDictionary* dictinprocesses){
NSLog(@"%@ - %@", [dictobjectForKey:@"ProcessID"], [dictobjectForKey:@"ProcessName"]);
}

以上代码在iOS8一下可以使用，在iOS9上加强了安全，不允许调用sysctl获取进程了。但是我觉得没有关系的，并发妨碍你做这件事 在非越狱的iPhone 6 (iOS 8.1.3) 上进行钓鱼攻击 (盗取App Store密码)，可通过检查系统版本完成钓鱼。
