我有一个TabBarController,其中一个选项卡有一个ImageView。此外,我有一个按钮来显示ImagePicker和以下代码:
- (void) imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info {
[self dismissModalViewControllerAnimated:YES];
[picker release];
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
imageView.image = image;
}
但调用此方法时,ImageView中的图像不会显示。
有什么想法吗?

首先,你首先要解雇你的选择器,你可以尝试:
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
imageView.image = image;
[self dismissModalViewControllerAnimated:YES];
或者你可以试试这个代表:
-(void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingImage:(UIImage *)image
editingInfo:(NSDictionary *)editingInfo {
NSData *chosenImage = UIImageJPEGRepresentation(image, 1.0);
yourImage.image = [UIImage imageWithData:chosenImage];
}
