我正在爲CodeSchool做一個項目,它需要你從AFNetworking數據庫導入信息。我已經完成了所有這些,並且在我的代碼中沒有錯誤,但是當我調試它並單擊ProfileViewController時,我得到線程1信號SIGABRT。線程1信號SIGABRT

這裏是在ProfileViewController.m代碼:

#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 

,這裏是整個錯誤,包括對lldl的BT:

你的問題是ProfileViewController.m 39行:

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

doesNotRecognizeSelector異常被拋出:

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

...表示正在調用未實現的方法。

ProfileViewController繼承自實現viewDidLoad的UIViewController。自定義實現不需要由子類提供。 –

+0

那麼我該如何解決這個問題?我是否需要執行viewDidLoad的自定義實現,或者是否應該重新排列或更改此代碼?我非常感謝你的幫助! – user2832346

您可以確認ProfileViewController.m中第39行的哪行代碼?從你的示例貼出的第39行是後面的空行:[self.scrollView addSubview:bigBirdView]; –

0

我也懷疑在下面的代碼,

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) - 他們是不提供的UIImageView像setImageWithURL任何方法:placeholderImage。閱讀的UIImageview

2日)的文檔 - 爲什麼你使用以下行主線程下載圖像,

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

下載圖像使用異步委託NSURLConnection的/塊法耶使用GCD。
