我想创建一个如下图所示的示例,而是从照片库中选择图像或使用相机拍照(如 facebook 应用程序)。这个视图是内置的还是我需要创建自定义视图?

所以你想要一个 UIActionSheet?
做这个:
UIActionSheet *actionSheet = [[UIActionSheet alloc]
initWithTitle:@"What do you want to do?"
delegate:self
cancelButtonTitle:@"Cancel"
destructiveButtonTitle:nil
otherButtonTitles:@"Camera", @"Photos", nil];
[actionSheet showInView:self.view];
[actionSheet release];
然后在 clickedButtonAtIndex 做这样的事情:
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
if ([[actionSheet buttonTitleAtIndex:buttonIndex] isEqualToString:@"Camera"]) {
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
}
else if ([[actionSheet buttonTitleAtIndex:buttonIndex] isEqualToString:@"Photos"]) {
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
}
[self presentModalViewController:picker animated:YES];
[picker release];
}
