我想在 tableview 单元格上的按钮上添加图像，这是我的代码，一切正常，但在选择图像后，它未设置或在 imagebutton 上不可见，请帮助我。 .....
在 cellForRowAtIndexpath 方法中
if(indexPath.row == 0)
{
cell.userInteractionEnabled = YES;
cell.textLabel.text =@"Your Profile Photo";
imageBtn = [[UIButton alloc]initWithFrame:CGRectMake(250, 5, 35, 35)];
[imageBtn setBackgroundImage:[UIImage imageNamed:@"AFPFriendThumbnail.png"] forState:UIControlStateNormal];
[imageBtn addTarget:self
action:@selector(myAction)
forControlEvents:UIControlEventTouchUpInside];
imageView.backgroundColor = [UIColor lightGrayColor];
[cell addSubview:imageBtn];
}
按钮上的 Action
-(void)myAction
{
UIImagePickerController * picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentModalViewController:picker animated:YES];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[picker dismissModalViewControllerAnimated:YES];
UIImage *image = [info valueForKey:UIImagePickerControllerOriginalImage];
[imageBtn setImage:image forState:UIControlStateSelected];
imageBtn.backgroundColor = [UIColor redColor];
[tableView_ reloadData];
}
最佳答案
尝试使用 UIControlStateNormal
[imageBtn setImage:image forState: UIControlStateNormal];
但我可以看到您在设置图像后重新加载 tableView，这将替换 imageBtn
imageBtn = [[UIButton alloc]initWithFrame:CGRectMake(250, 5, 35, 35)]; // Creating a button every time.
它应该无需重新加载即可工作，因为您保留了对 imageBtn 的引用，以便您可以直接设置。尝试删除 [tableView_ reloadData]
