按下按钮时出错EXC_BAD_ACCESS

当我按下我的按钮时，出现访问错误。错误：线程1：EXC_BAD_ACCESS（码= 1，地址= 0xd0a937db）按下按钮时出错EXC_BAD_ACCESS

TTest.h

@interface TTtest : NSObject 
{ 
    UIButton *monBouton ; 
    UIImage *skin; 


} 
- (void)initTest :(UIView*)vueDonne; 
-(void)test:(id)sender;

TTest.m

- (void)initTest :(UIView*)vueDonne 
    { 


      skin = [UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"boutonG" ofType:@"png"]]; 
      monBouton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; 
      monBouton.frame = CGRectMake(50, 50, 45, 50); 
      [monBouton setImage:skin forState:UIControlStateNormal]; 


     [monBouton addTarget:self action:@selector(test:) forControlEvents:UIControlEventTouchDown]; 

      [vueDonne addSubview: monBouton]; 
} 
    -(void)test:(id)sender //didn't work because i have the probleme 
    { 
    NSLog(@"test clicked"); 
    }

testViewController.m

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    TTtest *test =[[TTtest alloc] init]; 
    [test initTest:_testView]; //View of my application 
}

编辑：如果我添加monBouton = [[UIButton alloc] init]; 我得到SIGABRT

从它的外观来看，我认为你需要首先实例化UIButton'monBouton = [[UIButton alloc] init]'。试一试。 – carlodurso 2014-10-26 15:42:43

如果我添加了monBouton = [[UIButton alloc] init] 我遇到了一个SIGBART的问题，我把文本放在我的文章中 – Supernirito 2014-10-26 15:48:12

的原因崩溃的是，测试对象在接收到按钮动作dealloced 。

TTtest *test =[[TTtest alloc] init]; //dealloced after viewDidLoad

所以尽量使测试属性和使用self.test。

self.test =[[TTtest alloc] init];

是的！怎么样？我不明白为什么在它不起作用之前。你能解释一下吗？ – Supernirito 2014-10-26 16:01:30

现在它在工作吗？因为原来的测试对象是一个本地对象，它只存在于viewDidLoad方法中，超出范围，它被释放以节省内存使用，你的目标动作 - （void）test：（id）sender是在测试对象中定义的，当你点击按钮时不再存在。 – gabbler 2014-10-26 16:04:51

的问题并不像你所定义的选择“测试”

-(void)test: (id) sender 
    NSLog(@"test clicked");  
}

是的，我忘记了，但方法不起作用的原因是“访问不良”。 – Supernirito 2014-10-26 15:28:22
