我有UICollectionView和Header.I有textfield和image.I确实尝试push segue工作正常。但我需要调用segue！任何帮助将不胜感激

Header.h

@interface HeaderRV : UICollectionReusableView

@property (weak, nonatomic) IBOutlet UILabel *titleLabel;

@end

Header.m

@implementation HeaderRV

- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
    // Initialization code
}
return self;
}

if ([self.searchField isEditing]) {
    [self.searchField resignFirstResponder];
}
else{
    //segue need to be here
}

我遇到了和你一样的问题。它实际上相当棘手，因为你可以完成＆＃34;在collectionHeaderView＆＃34;中执行segue。完美的空项目（我试过）。我发现这个问题的关键是导航控制器的RootVC不是应用程序的初始VC 。
您可以通过在.m文件中添加以下行来解决这个问题，该文件显示了导航控制器的rootVC。

- (IBAction)next:(id)sender {
[theRootVCinNavigationController] *vc = [self.storyboard instantiateViewControllerWithIdentifier:@"[your identifier]"];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:[theRootVCinNavigationController]];
[self presentViewController:navigationController animated:YES completion:nil];
}
