栏按钮项以编程方式添加工具栏 [英] bar button item add toolbar programmatically

问题描述

我想以编程方式将按钮而不是条形按钮项添加到工具栏.之所以选择它，是因为按钮具有暗淡的信息.

I want to add button instead of bar button item into toolbar programmatically. I select it because button has image infodark defaut.

那如何以编程方式完成?

so how is this done programmatically?

推荐答案

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];
