自定义修改iPhone相机界面
很多情况下，我们需要自定义系统的相机拍照界面， 以下示例代码可以实现定制相机界面， 具体UI自己可以加入
1 - (void) setup: (UIView *) aView 2 { 3 //获取相机界面的view 4 self.plcameraview = [aView subviewWithClass:NSClassFromString(@"PLCameraView")]; 5 if (!plcameraview) return; 6 7 //相机原有控件全部透明 8 NSArray *svarray = [plcameraview subviews]; 9 for (int i = 1; i < svarray.count; i++) [[svarray objectAtIndex:i] setAlpha:0.0f]; 10 11 //加入自己的UI界面 12 #if 1 13 self.navbar = [[[UINavigationBar alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 44.0f)] autorelease]; 14 UINavigationItem *navItem = [[[UINavigationItem alloc] init] autorelease]; 15 navItem.rightBarButtonItem = BARBUTTON(@"Shoot", @selector(shoot:)); 16 navItem.leftBarButtonItem = BARBUTTON(@"Cancel", @selector(dismiss:)); 17 18 [(UINavigationBar *)self.navbar pushNavigationItem:navItem animated:NO]; 19 [plcameraview addSubview:self.navbar]; 20 #endif 21 } 22 23 //启动相机 24 - (void) getStarted: (id) sender 25 { 26 UIImagePickerController *ipc = [[UIImagePickerController alloc] init]; 27 ipc.sourceType = UIImagePickerControllerSourceTypeCamera; 28 [self presentModalViewController:ipc animated:YES]; 29 [self performSelector:@selector(setup:) withObject:ipc.view afterDelay:0.5f]; 30 }
