我正在尝试在用户选择图像后从 UIImagePickerController 推送 View Controller (用于额外编辑)。
推送成功。
但是当弹出该 View Controller 并且用户返回到编辑屏幕时,编辑屏幕不再可交互。有谁知道是什么问题。
-(void)didTapBtn:(id)sender
{
self.picker = [[UIImagePickerController alloc] init];
self.picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
self.picker.delegate = self;
self.picker.allowsEditing = YES;
[self presentViewController:self.picker animated:YES completion:nil];
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *image = [info objectForKey:UIImagePickerControllerEditedImage];
if (image == nil) {
image = [info objectForKey:UIImagePickerControllerOriginalImage];
}
if (image == nil) {
return;
}
self.test = [[BTTestViewController alloc] init];
self.test.delegate = self;
[self.picker pushViewController:self.test animated:YES];
}
//Called by BTTestViewController
-(void)didCancel
{
[self.picker popViewControllerAnimated:YES];
}
最佳答案
试试这个它在我的应用程序中工作:
UIImagePickerController *imagePicker;//put it in .h file
put it in .m file
imagePicker = [[UIImagePickerController alloc]init];
imagePicker.delegate = self;
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePicker.allowsEditing = YES;
[self presentViewController:imagePicker animated:YES completion:nil];
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"STEP-BY-STEP-STORY!" message: @"Camera is not available" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
[alert show];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *pickedImage = [info objectForKey:UIImagePickerControllerEditedImage];
imageData.image =[self resizeImage:imageData.image width:200 height:200];
[picker dismissViewControllerAnimated:YES completion:nil];
iphone_filtersViewController *nav=[[iphone_filtersViewController alloc]initWithNibName:@"iphone_filtersViewController" bundle:nil];
[self.navigationController pushViewController:nav animated:YES];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
// release Picker
[picker dismissViewControllerAnimated:YES completion:nil];
}
// iphone_filtersViewController method
-(IBAction)backButton
{
[self.navigationController popViewControllerAnimated:YES];
}
可能会有帮助。
