Question

我想在表格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。

如何在表格视图的右侧添加加号按钮。

Answer 1

如果您有导航栏，则应添加如下所示的UIBarButtonItem：

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

Answer 2

转到iPhone Interface Guidelines Page。
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。

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;

对于Swift

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