you can this,

  uiimageview *imageview = [[uiimageview alloc]initwithframe:cgrectmake(50, 50, 50, 50)];  imageview.image = [uiimage imagenamed:@"synch"];  // face image here imageview.image = [imageview.image imagewithrenderingmode:uiimagerenderingmodealwaystemplate];  // imageview.backgroundcolor = [uicolor yellowcolor]; imageview.tintcolor = [uicolor redcolor]; // set different tint color here , image color  [self.view addsubview:imageview]; 

image should png file. synch image in png format in example.
