ios - Whatsapp 类型编辑按钮 IOS master detail app

Question

我正在使用主详细信息模板开发一个应用程序。这里我默认有“编辑”和“添加”按钮。谁能指导我如何将默认编辑按钮更改为带有边框图像的编辑按钮，就像 Whatsapp 和 oblige 中的那样。

Answer 1

使用此代码:

UIImage* image_bk = [UIImage imageNamed:@"whatsAPP_image.png"];
CGRect frameimg = CGRectMake(0, 0, image_bk.size.width, image_bk.size.height);
UIButton *someButton = [[UIButton alloc] initWithFrame:frameimg];
[someButton setBackgroundImage:image_bk forState:UIControlStateNormal];
[someButton addTarget:self action:@selector(editAction)
     forControlEvents:UIControlEventTouchUpInside];
[someButton setShowsTouchWhenHighlighted:YES];

UIBarButtonItem *customEditButton =[[UIBarButtonItem alloc] initWithCustomView:someButton];
self.navigationItem.leftBarButtonItem=customEditButton;
