objective-c - 对按钮xcode视而不见的函数

Question

嗨，我有一个问题，我无法发送函数参数

-(IBAction)ukazObrat:(NSInteger *)cis {     
    stvrtyViewController *screen = [[stvrtyViewController alloc] initWithNibName:nil bundle:nil];
    screen.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
    [self presentModalViewController:screen animated:YES];
    screen.obratLabel.font = [UIFont systemFontOfSize: 12];
    screen.obratLabel.numberOfLines = 0;
    screen.obratLabel.text = [array objectAtIndex:cis];
    [screen release];   
}

我将此功能设置为按钮单击，但是当我向其添加参数时无法编译它。

button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button.titleLabel setLineBreakMode:UILineBreakModeWordWrap];    
[button.titleLabel setTextAlignment:UITextAlignmentLeft];       
button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;
[button setTitle:obratLable forState:UIControlStateNormal];
[button addTarget:self 
           action:@selector([self ukazObrat:minus]
 forControlEvents:UIControlEventTouchDown];             
button.frame = CGRectMake(0.0, 0.0, 250.0, 60.0);

它一直在工作，直到我在那里添加变量。
请帮忙

Answer 1

[button addTarget:self action:@selector(buttonHandler) forControlEvents:UIControlEventTouchDown];  

然后将 buttonHandler 定义为:

- (void)buttonHandler {
  [self ukazObrat:minus];
}

管理 minus然而是必要的。
