欄按鈕項以編程方式添加工具欄

Question

我想以編程方式將按鈕而不是條形按鈕項添加到工具欄。 我選擇它是因為按鈕具有暗淡的信息。

那么該如何以編程方式完成？

Answer 1

UIImage* image = [UIImage imageNamed:defaultImage];
CGRect frame = CGRectMake(0, 0, image.size.width, image.size.height);
UIButton* button = [[UIButton alloc] initWithFrame:frame];
[button setTitle:@"Display" forState:UIControlStateNormal & UIControlStateHighlighted];
[button setImage:image forState:UIControlStateNormal];
[button setImage:[UIImage imageNamed:selectedImage] forState:UIControlStateSelected];
[button addTarget:self action:@selector(button_Clicked:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *barButton = [[UIBarButtonItem alloc] initWithCustomView:button];

Answer 2

要在UIToolbar添加此按鈕，您需要以下代碼。 首先，您可以在之后初始化UIToolbar

NSMutableArray *buttons = [[NSMutableArray alloc] initWithCapacity:4];

[buttons addObject: barButtonItem];
[buttons addObject: btnFav];
[buttons addObject: btnGeneralPopOverController];
[buttons addObject: showInfo];   

[mytoolbar setItems:buttons animated:NO];
