解除UIImagePickerController
解除UIImagePickerController
提问于 2013-05-10 13:05:07
我尝试过每一种不同的方法来消除一个UIImagePickerController，但没有任何运气。我做错了什么。
- (IBAction)choosePhoto
{
self.picker = [[UIImagePickerController alloc] init];
self.picker.delegate = self;
self.picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[self presentModalViewController:self.picker animated:YES];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)imagePicker
{
NSLog(@"dismiss image picker");
[self dismissModalViewControllerAnimated:NO];
[[self.picker parentViewController] dismissModalViewControllerAnimated:NO];
[self.presentedViewController dismissModalViewControllerAnimated:NO];
[self.presentingViewController dismissModalViewControllerAnimated:NO];
// And every other way i could think of
}
- (void)imagePickerController:(UIImagePickerController *)imagePicker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
.. same stuff here
}我试图从父控制器、祖父母控制器、navigationController控制器和根控制器中显示选取器，但都不起作用。无论我做什么，我都不能忽视ImagePickerController。
请注意，每次都会调用日志语句。
干杯

尝试这一行。这可能对你有用。
[self.picker dismissModalViewControllerAnimated:NO];对于iOS 6和更高版本，请使用以下命令
[self.picker dismissViewControllerAnimated:NO completion:nil];还可以使用此代码来呈现选取器控制器
if ([self respondsToSelector:@selector(presentViewController:animated:completion:)]){
[self presentViewController:self.picker animated:YES completion:nil];
} else {
//To target iOS 5.0
[self presentModalViewController:self.picker animated:YES];

您运行的是iOS 6吗？如果是这样，presentModalViewController:将被弃用，并可能导致一些意外的结果。请尝试使用presentViewController:animated:completion:。
但从技术上讲，你需要做的就是：
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)imagePicker
{
[imagePicker dismissViewControllerAnimated:NO completion:nil];//Or call YES if you want the nice dismissal animation

对于Swift，请使用以下命令：
func imagePickerControllerDidCancel(picker: UIImagePickerController!) {
picker.dismissViewControllerAnimated(true, completion: nil)
