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"在表格的行和其他用户界面元素使用标准按钮"复制ContactAdd按钮(我将其保存为ContactAdd.png这里).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;
