1.添加点击事件

• storyboard添加

  -(void) onButtonClick:(id)sender{
      [sender setHighlighted:YES];
  }

• UIButton

  [button addTarget:self action:@selector(buttonClick:) forControlEvents:UIControlEventTouchUpInside];
  
  -(void)buttonClick:(UIButton *) button{
  
  }

• UIView

  UITapGestureRecognizer *tapGesturRecognizer=[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(onItemClick:)];
  [view addGestureRecognizer:tapGesturRecognizer];
  view.userInteractionEnabled = YES; // 可以理解为设置label可被点击
  
  -(void)onItemClick:(id)sender{
      NSInteger tag = 0;
      if([sender isKindOfClass:[UITapGestureRecognizer class]]){
          tag= ((UITapGestureRecognizer *) sender).view.tag;
      }else if([sender isKindOfClass:[UIView class]]){
          tag= ((UIView *) sender).tag;
      }

  注意：一个UITapGestureRecognizer只能对应一个View。

2.UIViewControl的打开和关闭(A->B)

• NavigationController
  在A中打开B
  [self.navigationController pushViewController:dest animated:YES];
  在B中关闭自己(实际是关闭栈顶)
  self.navigationController popViewControllerAnimated:<#(BOOL)#>
• UIViewControl
  在A中打开B

  presentViewController:dest animated:YES completion:^{

    NSLog(@"ok");
  }];

  在B中关闭自己
  [self dismissViewControllerAnimated:YES completion:nil];

3.自定义cell上的button点击事件

• 1.在cell里,.h写一个Block.

  @property (nonatomic,copy)void(^agreeBlock)();

• 2. 在cell里,.m写一个点点击事件.

     - (IBAction)agreeClick:(id)sender {
         if (self.agreeBlock) {
             self.agreeBlock();
         }
     }

• 3.在tableView中

  - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
      cell.telephoneBlock=^(){
          NSLog(@"phonenumber is ======%@",shopmodel.phone);
      };
