IOS 中的自定义表格视图单元格？

Question

I have custom UITableViewCell . UITableViewCell have one UILabel and one UIButton . I want when click button then text of label change color to "redColor". I don't process???

Answer 1

Inside your custom table view cell set touch up inside event for the button like this

[self.button addTarget:self action:@selector(clicked:) forControlEvents:UIControlEventTouchUpInside];

In the same class add the following method

-(IBAction) clicked:(id)sender {
    [self.label setTextColor:[UIColor redColor]];
}

Answer 2

one thing you can do is maintain an array whose each element represents the corresponding row number.
Initialize the array with 0 means all the label will have text color black.
Now set the index of each button equal to index path.row in cell for row method .
Now when the button is clicked set the value in array at index button.tag to 1 and others to 0 and reload tableview.
Now in cell for row check if items in the array at index indexpath.row ==1 then set the color of uilabel to red else black.
