我正在以編程方式創建一些barbutton項目,但第一個按鈕點擊選擇器沒有被調用。我在viewDidLoad中下面的代碼現在:UIBarButtonItem沒有響應
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
// self.navigationItem.leftBarButtonItem = self.editButtonItem;
_defaultBarColor = self.navigationController.navigationBar.tintColor;
[self loadPreferences];
self.spinner = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
self.btnSpinner = [[UIBarButtonItem alloc] initWithCustomView:self.spinner];
self.btnRefresh = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:@selector(refreshPressed:)];
self.lblLastUpdate = [[UIBarButtonItem alloc] initWithTitle:@" " style:UIBarButtonItemStylePlain target:nil action:nil];
[self.lblLastUpdate setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIFont boldSystemFontOfSize:13], UITextAttributeFont,nil] forState:UIControlStateNormal];
self.flexibleSpace = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
self.toolbarItems = [NSArray arrayWithObjects:self.btnRefresh,self.flexibleSpace,self.lblLastUpdate,self.flexibleSpace, nil];
self.detailViewController = (DetailViewController *)[[self.splitViewController.viewControllers lastObject] topViewController];
[self loadData];
我發現到目前爲止是,如果我設置的標籤選擇器(在工具欄第二項)的第一個項目的選擇,那麼,第一項選擇器被調用。
任何想法?
我自己解決了這個問題。至少可以說這是一個奇怪的問題。我發現如果第二個元素中的文本更長,第一個Barbutton的動作就不會被調用。縮短文本後,它開始正常工作。感謝您的輸入。 – userx
