我有两个名为obsPic1和obsPic2
他们从选择器/相机接收图像。这适用于一个图像，但任何更多图像都是相同的。我如何为多个图像执行此操作？我试过访问按钮发件人标签但得到未声明的标识符错误，我也尝试过使用if语句。这样做的正确方法是什么？
- (IBAction)addObsPhotoBtnPresssed:(id)sender {
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
LogCmd();
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.delegate = self;
imagePicker.allowsEditing = YES;
[self.editController presentModalViewController:imagePicker animated:YES];
//iPad
}
else {
if (self.pop) {
[self.pop dismissPopoverAnimated:YES];
}
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePickerController.delegate = self;
imagePickerController.allowsEditing = YES;
self.pop=[[UIPopoverController alloc] initWithContentViewController:imagePickerController];
[self.pop presentPopoverFromRect:((UIButton *)sender).bounds inView:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[picker dismissModalViewControllerAnimated:YES];
UIImage *image = [info objectForKey:UIImagePickerControllerEditedImage];
self.obsPic1.backgroundColor = [UIColor whiteColor];
self.obsPic1.image = image;
NSData *imageData = UIImagePNGRepresentation(image);
NSString *path = [ICUtils pathForDocument:@"obsPic.png"];
[imageData writeToFile:path atomically:NO];
UIImage *image2 = [info objectForKey:UIImagePickerControllerEditedImage];
self.obsPic2.backgroundColor = [UIColor whiteColor];
self.obsPic2.image = image2;
NSData *imageData2 = UIImagePNGRepresentation(image);
NSString *path2 = [ICUtils pathForDocument:@"obsPic2.png"];
[imageData2 writeToFile:path2 atomically:NO];
}
