我正在创建一个应用程序,我选择一个按钮,它会引导我到库中选择一张图片。我希望所选图片成为按钮的主要图像。 有人能帮助我吗?
以下是我用于访问库的代码:
- (IBAction)image1Pressed:(id)sender {
if([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypePhotoLibrary])
{
UIImagePickerController *picker1= [[UIImagePickerController alloc]init];
picker1.delegate = self;
picker1.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentViewController:picker1 animated:YES completion:nil];
[picker1 release];
}
}
任何帮助将不胜感激!

您需要为按钮创建一个插座,我们将其命名为“imageButton”。让图像选择器完成剩下的工作:
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
UIImage *btnImage = [info objectForKey:UIImagePickerControllerOriginalImage];
[imageButton setImage:btnImage forState:UIControlStateNormal];
}
完成。
