添加的照片不适合UIImageView的框架

Question

请帮助在UIImageView的框架中推送添加的照片。照片不适合相框。我已经做了相同的"IOS编程：大书牧场指南"第12章"相机"。添加照片之前： https://www.dropbox.com/s/o0uypvspuhvlkm2/Screen%20Shot%202013-10-27%20at%205.08.39%20PM.jpg 添加后： https://www.dropbox.com/s/u6qffb1l941cb0v/Screen%20Shot%202013-10-27%20at%205.09.02%20PM.jpg 我已经尝试了 UIImageView 的setContentMode – 不起作用。这是我的代码：

#pragma mark UIActionSheetDelegate
- (IBAction)displayActionSheet:(id)sender
{
    UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil
                                                             delegate:self
                                                    cancelButtonTitle:@"Cancel"
                                               destructiveButtonTitle:nil
                                                    otherButtonTitles:@"Take photo", @"Choose photo from gallery", nil];
    actionSheet.actionSheetStyle = UIActionSheetStyleDefault;
    [actionSheet showInView:self.view];
}
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
    switch (buttonIndex) {
        case 0:
            [self takePhoto];
            break;
        case 1:
            [self choosePhoto];
            break;
    }
}
#pragma mark UIImagePickerControllerDelegate
- (void)takePhoto {
    UIImagePickerController *pickerControllerTakePhoto = [[UIImagePickerController alloc] init];
    [pickerControllerTakePhoto setSourceType:UIImagePickerControllerSourceTypeCamera];
    [pickerControllerTakePhoto setDelegate:self];
    [self presentViewController:pickerControllerTakePhoto animated:YES completion:nil];
}
- (void)choosePhoto {
    UIImagePickerController *pickerControllerChoosePhoto = [[UIImagePickerController alloc] init];
    [pickerControllerChoosePhoto setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
    [pickerControllerChoosePhoto setDelegate:self];
    [self presentViewController:pickerControllerChoosePhoto animated:YES completion:nil];
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    UIImage *myPhoto = [info objectForKey:UIImagePickerControllerOriginalImage];
    [photoView setImage:myPhoto];
    [self dismissViewControllerAnimated:YES completion:NULL];
}

我的"加号"或"添加"按钮调用带有对话框的操作表，因此我从图库中选择照片，结果与第二个屏幕截图相同。

Answer 1

设置图像视图属性：

imageView.clipsToBounds = YES;
imageView.contentMode = UIViewContentModeScaleAspectFill;

两者都可以在界面生成器中设置。

Answer 2

所以我找到了打扰我的代码行，这一切都是因为我的自定义单元格，我把这些单元格放在我的表格视图中：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell = nil;
    if (indexPath.row == 0) {
        photoView = (UIImageView *)[photoCell viewWithTag:1]; // this is the first custom cell in my tableview and this line which I put on the model of the book isn't needed
        cell = photoCell;
