当前视图控制器在iOS 9上无法正常工作,当我按下按钮时,它没有重定向到要呈现的视图控制器。
为什么会发生这种情况?
我尝试了以下代码:
RegistrationViewController * viewController =[[UIStoryboard storyboardWithName:@"Registration" bundle:nil] instantiateViewControllerWithIdentifier:@"RegistrationViewController"];
[self presentViewController:viewController animated:YES completion:nil];
我也尝试了以下代码。
UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"Registration"
bundle:nil];
RegistrationViewController *add =
[storyboard instantiateViewControllerWithIdentifier:@"RegistrationViewController"];
[self presentViewController:add animated:YES completion:^{
dispatch_async(dispatch_get_main_queue(), ^{
[self presentViewController:add
animated:YES
completion:nil];
});
}];

这里是我的完整代码。我正在使用Xcode 7,并在iOS 9上运行它。
#import "LoginViewController.h"
#import "RegistrationViewController.h"
@interface LoginViewController ()
@end
@implementation LoginViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)actionRegistrationClicked:(id)sender
{
RegistrationViewController * viewController =[[UIStoryboard storyboardWithName:@"Registration" bundle:nil] instantiateViewControllerWithIdentifier:@"RegistrationViewController"];
[self presentViewController:viewController animated:YES completion:nil];
}
@end
