我像这样呈现我的视图控制器：
- (void) showImagePicker:(UIImagePickerControllerSourceType)source {
[self dismissKeyboard];
if(self.cameraImagePicker == nil) {
self.cameraImagePicker = [[UIImagePickerController alloc] init];
}
self.cameraImagePicker.delegate = self;
self.cameraImagePicker.allowsEditing = YES;
self.cameraImagePicker.sourceType = source;
//[self presentModalViewController:self.cameraImagePicker animated:YES];
[self presentViewController:self.cameraImagePicker animated:NO completion:nil];
}
然而，每当我致电[self dismissViewControllerAnimated:NO completion:nil];时，它不仅会关闭图像选择器，还会关闭我当前所处的视图。
如何在不杀死当前视图的情况下关闭UIImagePickerController？
修改
这是我的解雇代码。
dispatch_queue_t queue = dispatch_get_main_queue();
dispatch_async(queue, ^{
NSURL *url = [NSURL URLWithString:[[responseObject objectForKey:@"result"] objectForKey:@"image"]];
NSData *data = [NSData dataWithContentsOfURL:url];
self.displayPictureView.image = [UIImage imageWithData:data];
data = nil;
[self.cameraImagePicker dismissViewControllerAnimated:NO completion:nil];
});
和控制台日志。
