4按鈕標題每次點擊更改

Question

即時消息在我的應用程序中有四個按鈕，即時獲取數組中的按鈕標題，每當我點擊任何按鈕時，我都想更改4個按鈕標題，但是這裏點擊的按鈕標題只是改變了在這裏我的代碼，

-(IBAction)setting:(id)sender 
{ 
int value = rand() % ([arraytext count] -1) ; 
UIButton *mybuton = (UIButton *)sender; 
[mybuton setTitle:[arraytext objectAtIndex:value] forState:UIControlStateNormal]; 
} 

更新

-(IBAction)answersetting:(id)sender 
{ 

UIButton *mybutton = (UIButton *)sender; 
static int j = 0; 
if(sender == mybutton) 
    j++; 
if (j >= arcount) 
{ 
    j = 0; 
} 
else if(j < 0) 
{ 
    j = arcount - 1; 
} 

CATransition *transition = [CATransition animation]; 
transition.duration = 1.0f; 
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut]; 
transition.type = kCATruncationMiddle; 

[animage.layer addAnimation:transition forKey:nil];  
animage.image=[arimage objectAtIndex:j]; 

for(UIView *view in self.view.subviews) 
{ 
    if([view isKindOfClass:[UIButton class]]) 
    { 
     UIButton *button = (UIButton *)view; 
     if(button.tag == 1||button.tag == 2||button.tag == 3||button.tag == 4) 
     { 
      int value = rand() % ([artext count] -1) ; 
      NSMutableDictionary *dictionary = [[NSMutableDictionary alloc]init]; 
      [dictionary setValue:animage.image forKey:@"button"]; 
      [button setTitle:[artext objectAtIndex:value] forState:UIControlStateNormal]; 

     } 
    } 
} 

}

我有4個按鈕連接這種方法，我想改變這一切的按鈕標題每當我點擊任何按鈕，請幫助編碼

Answer 1

因爲sender僅包含您點擊的UIButton。
要更改所有UIButton的標題，您需要一個循環。
將tag設置爲全部4 buttons。

那麼做到這一點 -

-(IBAction)setting:(id)sender 
{ 
    int value = rand() % ([arraytext count] -1) ; 
    for(UIView *view in self.view.subviews) 
    { 
     if([view isKindOfClass:[UIButton class]]) 
     { 
      UIButton *button = (UIButton *)view; 
      if(button.tag == 1||button.tag == 2||button.tag == 3||button.tag == 4) 
      { 
       [button setTitle:[arraytext objectAtIndex:value] forState:UIControlStateNormal]; 
      } 
     } 
    } 
}
