14.设置摄像机参数
条件：摄像机连接成功
语法：
1）函数
-(int)setParams:(NSDictionary*)dic;//设置参数 参数：(NSDictionary*)dic：需要设置的参数
2）消息通知
FOUNDATION_EXPORT NSString* const IPCamera_SetParam_Result;
3) 设置成功后的消息回调
-(void)IPCamera_response_function:(NSNotification*)note;
IPCamera.h宏定义了两种注册消息的方法
#define ADD_IPCAMERA_RESPONSE_WITHOUT_ARG(notice_name) \
[[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(IPCamera_response_function:) name: notice_name object: nil]
#define ADD_IPCAMERA_RESPONSE_WITH_ARG(notice_name,camera_object) \
[[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(IPCamera_response_function:) name: notice_name object: camera_object]
示列： 设置cam频率 60HZ: int frequency_ = 0 50HZ: int frequency_ = 1 室外: int frequency_ = 2
1）注册消息通知
ADD_IPCAMERA_RESPONSE_WITH_ARG( IPCamera_SetParam_Result, cam_)
2)设置参数
NSDictionary* dic = [ NSDictionary dictionaryWithObjectsAndKeys:
[NSString stringWithFormat:@"%d",frequency_ ], @"powerfreq",@"1",@"save",@"1",@"reinit_camera", nil];
[cam_ setParams:dic ];
3）参数设置成功后的消息回调
-(void)IPCamera_response_function:(NSNotification*)note
{
NSDictionary* dic = note.userInfo;
if( [note.name isEqualToString: IPCamera_SetParam_Result ])
{
NSLog(@"设置参数成功！");}
}
