BarButton項目在單擊導航欄時正在獲取事件

Question

我在導航欄（自定義導航控制器）中添加自定義后退按鈕，如下所示：-

UIButton *button =  [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:[UIImage imageNamed:@"goback.png"] forState:UIControlStateNormal];
[button addTarget:self action:@selector(handleBackButtonClick) forControlEvents:UIControlEventTouchUpInside];
[button setFrame:CGRectMake(0, 0, 32, 32)];//same as image width and height
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button];

當我單擊靠近條形按鈕項目（左右）時，條形按鈕正在發生觸摸事件。

我想防止這種奇怪的行為。

我正在為iOS7開發應用程序。

Answer 1

我嘗試調整barButtonItem的width屬性，但是沒有運氣。

    self.navigationItem.leftBarButtonItem.width = 32;

但我有一個有趣的解決方案，

您可以在自定義視圖中使用兩個按鈕，一個用於實現所需的方法，另一個用於虛擬按鈕

UIButton *button =  [UIButton buttonWithType:UIButtonTypeCustom];

[button setImage:[UIImage imageNamed:@"goBack.png"] forState:UIControlStateNormal];

[button addTarget:self action:@selector(handleBackButtonClick) forControlEvents:UIControlEventTouchUpInside];

[button setFrame:CGRectMake(0, 0, 32, 32)];//same as image width and height

UIBarButtonItem *barButton = [[UIBarButtonItem alloc] initWithCustomView:button];

UIButton *dummyButton = [UIButton buttonWithType:UIButtonTypeCustom];

UIBarButtonItem *dummyBarButton = [[UIBarButtonItem alloc] initWithCustomView:dummyButton];

self.navigationItem.leftBarButtonItems = @[barButton,dummyBarButton];
