如何从c方法iOS调用Objective c方法

Question

我想从c =＆gt;调用数据目标c（ios）。

下面我分享了我的代码截图。

Answer 1

声明id referance变量

#import <Cocoa/Cocoa.h>

id refToSelf;

比使用

打电话

[refToSelf cameraCapture];

Answer 2

到目前为止，你有正确的线条。但是你忘了在你的.c

中包含.h文件

假设您要cameraCapture()在mycclass.c文件中调用mycclass.c方法。

在 #include "myiosclass.h" void cameraCapture(){ //your c code goes here... }

中

myiosclass.h

在extern void cameraCapture();

中

myiosclass.m

在-(void)myMethod { cameraCapture(); //Called your C method. //Rest of objective c code ... }

中

{
  "rtVisitInfoOpObjV1":{
  "version":"1",
  "visitorId":"vis1",
  "dwellTime":"0",
  "poiId":"poi1",
  "srId":"sr1",
  "zoneId":"zone1",
  "poiProximityConfidence":"0",
  "zoneProximityConfidence":"0",
  "poiPresenceConfidence":"15",
  "zonePresenceConfidence":"0",
  "normalizedTime":"1489574975000"
 }
}

希望它会对你有所帮助。

将当前视图控制器作为c方法中的参数传递并使用

void CameraCaptureFromC(long cCameraClient,
                     const char *imageName,
                              void *object,
                  MasterViewController *vc) {
  NSLog(@"glfm:Camera Call");
  [vc addAllImages];
  //your code
}

    someMethod();
}

void someMethod(){
    printf("test123\n");
    [ViewController someMethod2:@"Calling objective C Method from C  method"];
}
+(void)someMethod2:(id)sender{
    NSLog(@"Message: %@",sender);
}
