我正在开发一款iPhone应用程序,在我的应用程序中,有些页面必须从图库中获取图像。所有工作在iPhone和iPad上都很好,但我不能总是通过imagePickerControllerDidCancel()
获得图像。
此方法仅在我选择图像时触发事件..我无法找到任何解决方案。
任何帮助都会非常明显!
if (!self.takeImage) self.takeImage = [[UIImagePickerController alloc]init];
[[self.takeImage navigationBar] setTintColor:[UIColor blackColor]];
self.takeImage.sourceType = UIImagePickerControllerSourceTypeCamera;
self.takeImage.delegate = self;
[self presentViewController:self.takeImage animated:YES completion:nil];

您需要在iPad上添加UIPopoverController
以显示UIImagePickerController
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:picker];
[popover presentPopoverFromRect:self.selectedImageView.bounds inView:self.selectedImageView permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
self.popOver = popover;
} else {
[self presentModalViewController:picker animated:YES];
}

如果您的ipad iOS版本低于7.0,则可能会出现问题。尝试使用presentPopoverFromRect:而不是presentViewController。
在这里,这段代码可能有所帮助,
if (([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) && SYSTEM_VERSION_LESS_THAN(@"7.0"))
{
self.popOver = [[UIPopoverController alloc] initWithContentViewController:imagePickerController];
[self.popOver presentPopoverFromRect:CGRectMake(0.0, 0.0, 600.0,500.0) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];
}
else
[self presentViewController:imagePickerController animated:YES completion:nil];
