ios – 使用UIImagePickerController时的内存警告

当您拍照并按下相机视图控制器上的“使用照片”按钮时,我会收到内存警告.目的是按下“使用照片”按钮,它会改变ImageView的内容.

我认为内存问题可能是由于捕获的图像是全屏的,而ImageView是250h 250w.但我尝试缩小相机拍摄的图像大小,然后将其分配给ImageView.然而,即使我将其调整为100 x 100,这仍然无效.

其次,我没有将相机拍摄的照片分配给ImageView,但它仍然有内存警告.

我在这里查看了其他答案并尝试了上面的两个,但它仍然存在.我将在下面显示我的代码.这会影响我对应用商店的提交吗？当然,如果这是一个常见的事件,它是一个错误或有一个解决方案？如果可以查看提供的代码并发现错误或建议如何处理此内存警告,那将会很棒？

我的应用程序95％完成了此内存警告,所以它接近提交时间.

我的代码：

- (IBACtion)takePhoto:(id)sender {

self.imagePicker = [[UIImagePickerController alloc] init];
self.imagePicker.delegate = self;
self.imagePicker.allowsEdiTing=NO;

if ([UIImagePickerController issourceTypeAvailable:UIImagePickerControllersourceTypeCamera]) {
     [self.imagePicker setsourceType:UIImagePickerControllersourceTypeCamera];
    [self presentViewController:self.imagePicker animated:YES completion:NULL];

}
else{
    [self.imagePicker setsourceType:UIImagePickerControllersourceTypePhotoLibrary];
    [self presentViewController:self.imagePicker animated:YES completion:NULL];
 }



}

- (IBACtion)choosePhoto:(id)sender {
self.imagePicker2 = [[UIImagePickerController alloc] init];
self.imagePicker2.delegate = self;
self.imagePicker2.allowsEdiTing=NO;
[self.imagePicker2 setsourceType:UIImagePickerControllersourceTypePhotoLibrary];
[self presentViewController:self.imagePicker2 animated:YES completion:NULL];
}

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

self.image = [info objectForKey:UIImagePickerControllerOriginalImage];
CGRect rect = CGRectMake(0,100,100);

UIGraphicsBeginImageContext( rect.size );
[self.image drawInRect:rect];
UIImage *picture1 = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
[self.snapImage setImage:picture1];

[self.uploadImageBtn setHidden:NO];
[self dismissviewControllerAnimated:YES completion:NULL];
}

-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker{

[self dismissviewControllerAnimated:YES completion:NULL];
}
