如何在objective-c中将加号按钮添加到表格视图的右侧？

Question

我想在表视图的右侧添加加号按钮，以在其他视图中添加该单元格的内容。

如何在表视图的右侧添加加号按钮。

Answer 1

如果你有一个导航栏，你应该像这样添加一个UIBarButtonItem：

UIBarButtonItem *addButton = [[UIBarButtonItem alloc]      
    initWithBarButtonSystemItem:UIBarButtonSystemItemAdd
    target:self action:@selector(addButtonPressed:)];
self.navigationItem.rightBarButtonItem = addButton;

Answer 2

1. 转到iPhone 界面指南页面 。

2. 在“表格行和其他用户界面元素中使用的标准按钮”下，复制ContactAdd按钮（我将其另存为ContactAdd.png）。 将其添加到您的项目中。

3. 在cellForRowAtIndexPath：（NSIndexPath *）indexPath方法中添加：

    UIImage *image = [UIImage imageNamed:@"ContactAdd.png"]; UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; //You can also Use: //UIButton *button = [UIButton buttonWithType:UIButtonTypeContactAdd]; CGRect frame = CGRectMake(0.0, 0.0, image.size.width, image.size.height); //match the button's size with the image size button.frame = frame; [button setBackgroundImage:image forState:UIControlStateNormal]; // set the button's target to this table view controller so you can open the next view [button addTarget:self action:@selector(yourFunctionToNextView:) forControlEvents:UIControlEventTouchUpInside]; button.backgroundColor = [UIColor clearColor]; cell.accessoryView = button;

let addButton = UIBarButtonItem.init(barButtonSystemItem: .Add,
                                     target: self,
                                     action: #selector(yourFunction))
self.navigationItem.rightBarButtonItem = addButton
