Question

嘿我自动将我的项目转换为ARC，我唯一需要解决的是Xcode更改了大小为[8]到[4]的数组（仍然不知道那里发生了什么）

然而，我现在意识到我遇到了另一个问题：每当我点击弹出窗口中的按钮时，如果应用程序链接到IBAction，应用程序就会崩溃。如果我删除对标题和主文件的引用，则该按钮是可单击的，但是只要我将其分配给方法（即使该方法为空），整个应用程序jut会冻结/崩溃。

这是我启动弹出窗口的方式：

PopUpViewController *popViewController =
[[PopUpViewController alloc]  initWithNibName:@"PopUpViewController" bundle:nil];

[popViewController setTitle:@"This is a popup view"];
[popViewController showInView:self.view
                                 animated:YES];
popViewController.view.center=self.view.center;

非常基本的东西，我把它从我在网上发现的教程中删除了。我的标题是：

@interface PopUpViewController : UIViewController

- (IBAction)baa:(id)sender;
@property (strong, nonatomic)  UIButton *ba; // I was trying to add those buttons as properties here
@property (strong, nonatomic) IBOutlet UIButton *kl; //but no luck whatsoever

@property (strong, nonatomic) IBOutlet UIView *popUpView;
@property (strong, nonatomic) IBOutlet UIView *ppp;

- (IBAction)openSomething:(id)sender;
- (IBAction)openYoutube:(id)sender;
- (IBAction)openFacebook:(id)sender;

- (void)showInView:(UIView *)aView animated:(BOOL)animated;

@end

我的主要

#import "PopUpViewController.h"

@interface PopUpViewController ()

@end 

@implementation PopUpViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {

} 
    return self;
}
- (void)showAnimate
{
  // not important for this question
}

- (void)removeAnimate
{
  // shortened
}

- (IBAction)baa:(id)sender{
//    NSLog(@"asd"); I commented it out, but even an empty method kills the app
// only if I leave a button unassigned to any method, the app "survives" a button click

}

- (IBAction)openSomething:(id)sender
{
   // [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.test.de"]];
}

- (IBAction)openYoutube:(id)sender
{
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"https://www.youtube.com/"]];
}

- (IBAction)openFacebook:(id)sender
{
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"https://www.facebook.com/"]];

}

- (void) doSomething{
 // also tried an empty method with a "new" name over here to eliminate any caching errors, no luck   
}

- (IBAction)closePopup:(id)sender {
    [self removeAnimate];
}

- (void)showInView:(UIView *)aView animated:(BOOL)animated
{
    [aView addSubview:self.view];
    if (animated) {
        [self showAnimate];
    }
}


- (void)viewDidLoad
{
    self.view.backgroundColor=[[UIColor blackColor] colorWithAlphaComponent:.0];
    self.popUpView.layer.cornerRadius = 5;
    self.popUpView.layer.shadowOpacity = 1.0;
    self.popUpView.layer.shadowOffset = CGSizeMake(0.2f, 0.2f);


    [super viewDidLoad];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
}


@end

我能做些什么不同的想法？我现在把所有内容都引用到其他所有内容上，我甚至不知道它之前的样子，但我不知道它是否与引用有关。

非常感谢，Alex

我能够自己搞清楚：

在我的主ViewController的标题中，我添加了

@property (strong, nonatomic) PopUpViewController *popViewController;

仍然引发了崩溃。但后来我将弹出的“开放”块调整为

_popViewController =
            [[PopUpViewController alloc]  initWithNibName:@"PopUpViewController" bundle:nil];                 

            [_popViewController setTitle:@"This is a popup view"];
            [_popViewController showInView:self.view
                                 animated:YES];
            _popViewController.view.center=self.view.center;

（添加了下划线），现在它再次完美运作。

实际上我很好奇为什么它之前有用，但我不打算进一步调查这个。
