で投稿を表示できる親ビューがありますUITableView。そのNavigation Bar中には、押すUIView subclassと表示され、画面の上部に表示される投稿ボタンがあります。UIViewタップするUIImagePickerControllerと、ユーザーがサービスに投稿する画像を選択できるように表示したいという画像があります。私のサブビューはUIImagePickerControllerを表示できないView Controllerではないため、これを行うにはどうすればよいですか。
以下は私のサブビューコードです。
#import "PostView.h"

originalFrame = frame;
NSArray *xib = [[NSBundle mainBundle] loadNibNamed:@"PostView" owner:self options:nil];
PostView *view = [xib objectAtIndex:0];
[view setBackgroundColor:[UIColor whiteColor]];
[view setAlpha:0.7f];
attachedLabel = [[UILabel alloc] initWithFrame:CGRectMake(204, 212, 56, 21)];
attachedLabel.textColor = [UIColor blackColor];
[attachedLabel setText:@"Attached"];
attachedLabel.backgroundColor = [UIColor clearColor];
attachedLabel.font = [UIFont fontWithName:text_font_name size:12.0];

[characterLimit setTextAlignment:NSTextAlignmentRight];

[self.textView setAlpha:0.7f];
[self.textView setTextColor:[UIColor whiteColor]];
[self.textView setBackgroundColor:[UIColor clearColor]];
self.layer.cornerRadius = 10.0f;
self.layer.masksToBounds = YES;
[self addSubview:view];
[self addSubview:characterLimit];
[self addSubview:attachedLabel];
[self addSubview:attachImage];
}
return self;
