關閉UIImagePickerController

Question

我已經嘗試了任何運氣的解僱UIImagePickerController的每一個變化。我究竟做錯了什麼。

- (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 
} 

我試圖從父母，祖父母目前的選擇器，navigationController和根控制器和沒有什麼作品。我永遠不會解僱ImagePickerController。

請注意每次都會調用日誌語句。

乾杯

Answer 1

試試這條線。它可能適合你。

[self.picker dismissModalViewControllerAnimated:NO]; 

而對於iOS 6的，後來用這個

[self.picker dismissViewControllerAnimated:NO completion:nil]; 

還可以使用此代碼來展示你的選擇器控制器

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]; 
} 

Answer 2

您是否正在運行iOS 6？如果是這樣，presentModalViewController:已棄用，可能會導致一些意外的結果。改爲使用presentViewController:animated:completion:。

但在技術上，這裏就是你應該做的：

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)imagePicker 
{ 
    [imagePicker dismissViewControllerAnimated:NO completion:nil];//Or call YES if you want the nice dismissal animation 
} 

Answer 3

對於SWIFT使用本...

func imagePickerControllerDidCancel(picker: UIImagePickerController!) 
{ 
    picker.dismissViewControllerAnimated(true, completion: nil) 
} 

Answer 4

對於斯威夫特4：

func imagePickerControllerDidCancel(_ picker: UIImagePickerController) { 
     picker.dismiss(animated: true, completion: nil) 
}
