线程1信号SIGABRT

我正在为CodeSchool做一个项目，它需要你从AFNetworking数据库导入信息。我已经完成了所有这些，并且在我的代码中没有错误，但是当我调试它并单击ProfileViewController时，我得到线程1信号SIGABRT。线程1信号SIGABRT

这里是在ProfileViewController.m代码：

#import "ProfileViewController.h" 
#import "UIKit+AFNetworking/UIImageView+AFNetworking.h" 

@interface ProfileViewController() 

@end 

@implementation ProfileViewController 

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil 
{ 
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; 
if (self) { 
    self.title = @"Profile"; 
    self.tabBarItem.image = [UIImage imageNamed:@"tab_icon_profile"]; 
} 
return self; 
} 

- (void)viewDidLoad 
{ 
[super viewDidLoad]; 
self.scrollView =[[UIScrollView alloc] initWithFrame:self.view.bounds]; 
self.scrollView.contentSize = CGSizeMake(320, 480); 
self.scrollView.autoresizingMask = (UIViewAutoresizingFlexibleHeight| UIViewAutoresizingFlexibleWidth); 

self.view.backgroundColor = [UIColor darkGrayColor]; 

UIImageView *bigBirdView = [[UIImageView alloc] init]; 
bigBirdView.frame = CGRectMake(20, 20, 100, 114); 
[bigBirdView setImageWithURL:[NSURL URLWithString:@"http://images3.wikia.nocookie.net/__cb20100901224145/muppet/images/f/f8/Big-bird-NEW.jpg"] placeholderImage:[UIImage imageNamed:@"placeholder.png"]]; 
[self.scrollView addSubview:bigBirdView]; 

UILabel *nameLabel = [[UILabel alloc] initWithFrame:CGRectMake(20, 140, 280, 40)]; 
[nameLabel setBackgroundColor:[UIColor clearColor]]; 
[nameLabel setTextColor:[UIColor whiteColor]]; 
nameLabel.text = @"Name: Big Bird"; 
[self.scrollView addSubview:nameLabel]; 

UILabel *cityLabel = [[UILabel alloc] initWithFrame:CGRectMake(20, 200, 280, 40)]; 
[cityLabel setBackgroundColor:[UIColor clearColor]]; 
[cityLabel setTextColor:[UIColor whiteColor]]; 
cityLabel.text = @"From: Sesame Street"; 
[self.scrollView addSubview:cityLabel]; 

UITextView *biography= [[UITextView alloc] initWithFrame:CGRectMake(12, 260, 200, 200)]; 
[biography setBackgroundColor:[UIColor clearColor]]; 
biography.font = [UIFont fontWithName:@"Helvetica" size:15]; 
[biography setTextColor:[UIColor whiteColor]]; 
biography.editable = NO; 
biography.text = @"Big Bird likes long walks on the beach, hanging with friends, and singing songs about various subjects. Big Bird is also really into organic bird seed."; 
[self.scrollView addSubview:biography]; 

UILabel *memberSince = [[UILabel alloc] initWithFrame:CGRectMake(20, 400, 280, 40)]; 
[memberSince setBackgroundColor:[UIColor clearColor]]; 
[memberSince setTextColor:[UIColor whiteColor]]; 
memberSince.text = @"Member Since: 1969"; 
[self.scrollView addSubview:memberSince]; 

[self.view addSubview:self.scrollView]; 


} 

- (void)didReceiveMemoryWarning 
{ 
[super didReceiveMemoryWarning]; 
// Dispose of any resources that can be recreated. 
} 

@end

，这里是整个错误，包括对lldl的BT：

你的问题是ProfileViewController.m 39行：

frame #12: 0x0000415c InstaPhoto`- [ProfileViewController viewDidLoad](self=0x0899ef40, _cmd=0x007b1d27) + 1260 at ProfileViewController.m:39

该doesNotRecognizeSelector异常被抛出：

frame #9: 0x023fd903 CoreFoundation`-[NSObject(NSObject) doesNotRecognizeSelector:] + 275

...表示正在调用未实现的方法。

ProfileViewController继承自实现viewDidLoad的UIViewController。自定义实现不需要由子类提供。 –

那么我该如何解决这个问题？我是否需要执行viewDidLoad的自定义实现，或者是否应该重新排列或更改此代码？我非常感谢你的帮助！ – user2832346

您可以确认ProfileViewController.m中第39行的哪行代码？从你的示例贴出的第39行是后面的空行：[self.scrollView addSubview：bigBirdView]; –

我也怀疑在下面的代码，

UIImageView *bigBirdView = [[UIImageView alloc] init]; 
bigBirdView.frame = CGRectMake(20, 20, 100, 114); 
[bigBirdView setImageWithURL:[NSURL URLWithString:@"http://images3.wikia.nocookie.net/__cb20100901224145/muppet/images/f/f8/Big-bird-NEW.jpg"] placeholderImage:[UIImage imageNamed:@"placeholder.png"]]; 
[self.scrollView addSubview:bigBirdView];

月1日） - 他们是不提供的UIImageView像setImageWithURL任何方法：placeholderImage。阅读的UIImageview

2日）的文档 - 为什么你使用以下行主线程下载图像，

[bigBirdView setImageWithURL:[NSURL URLWithString:@"http://images3.wikia.nocookie.net/__cb20100901224145/muppet/images/f/f8/Big-bird-NEW.jpg"] placeholderImage:[UIImage imageNamed:@"placeholder.png"]];

下载图像使用异步委托NSURLConnection的/块法耶使用GCD。
