Question

我想知道,是否有一种方法使正常的“+”纽芬兰文在<条码>中定制“initWith BarButtonSystem:UIBarButtonSystemAdd方法。

这是我的现行法典:

UIBarButtonItem *addButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:nil action:nil];
    self.navigationItem.leftBarButtonItem = addButtonItem;
    [addButtonItem release];

感谢任何要点。

Answer 1

What i did to a 3rd party TableView package was creating my own UIBarButtonItem and settig the target & action properties to the ones of the original button. In some cases this will work and in some cases it won t (like if the target checks the source-object for a specific object) - but it s worth a try!

除<条码> 字标/代码”外,您可更改以这种方式创建的条形纽。如果您正在寻找其他定制,则最好有initWithImage: 风格:target:action:。

再次感谢马丁。我认为,展示守则可能是有益的。

而不是:

UIBarButtonItem *addButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:nil action:nil];
    self.navigationItem.leftBarButtonItem = addButtonItem;
    [addButtonItem release];

我只是利用了这一点:

UIBarButtonItem *addButton = [[UIBarButtonItem alloc]
                                  initWithTitle:@"Add" style:UIBarButtonItemStyleBordered 
                                  target:nil action:nil];
    self.navigationItem.leftBarButtonItem = addButton;
    [buttons addObject:addButton];
    [addButton release];
