iOS imagePicker使用方法,方便使用!三步轻松搞定!

自己总结的修改头像的方法,只为方便自己查询使用!转发

步骤:1、遵守代理协议

<UIImagePickerControllerDelegate,UINavigationControllerDelegate,UIActionSheetDelegate>

2、点击事件{

 

    UIActionSheet *choosePhotoActionSheet;

    

    if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {

        choosePhotoActionSheet = [[UIActionSheet alloc] initWithTitle:NSLocalizedString(@"选取图片", @"")

                                                             delegate:self

                                                    cancelButtonTitle:NSLocalizedString(@"取消", @"")

                                               destructiveButtonTitle:nil

                                                    otherButtonTitles:NSLocalizedString(@"相机", @""), NSLocalizedString(@"相册", @""), nil];

    } else {

        choosePhotoActionSheet = [[UIActionSheet alloc] initWithTitle:NSLocalizedString(@"选取图片", @"")

                                                             delegate:self

                                                    cancelButtonTitle:NSLocalizedString(@"取消", @"")

                                               destructiveButtonTitle

                                                                     :nil

                                                    otherButtonTitles:NSLocalizedString(@"相册", @""), nil];

    }

    

    [choosePhotoActionSheet showInView:self.view];

 

}

3、实现代理方法

#pragma mark - UIActionSheetDelegate

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex

{

    NSUInteger sourceType = 0;

    if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {

        switch (buttonIndex) {

            case 0:

                sourceType = UIImagePickerControllerSourceTypeCamera;

                break;

            case 1:

                sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

                break;

            case 2:

                return;

        }

    } else {

        if (buttonIndex == 1) {

            return;

        } else {

            sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;

        }

    }

    

    UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];

    imagePickerController.delegate = self;

    imagePickerController.allowsEditing = YES;

    imagePickerController.sourceType = sourceType;

    [self presentViewController:imagePickerController animated:YES completion:^{

        

    }];

}

 

#pragma mark - UIImagePickerControllerDelegate

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

{

    [self dismissViewControllerAnimated:YES completion:^{

        

    }];

    self.tmpHeaderImg = [info objectForKey:UIImagePickerControllerEditedImage];

    [self.imageViewUserHead setImage:self.tmpHeaderImg];

    [self uploadImage];

}

 

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker

{

    [self dismissViewControllerAnimated:YES completion:^{

        

    }];

}
