如何实现UISegmentcontrol的事件呢？

如题，谁能告诉我如何实现UISegmentcontrol的事件呢？

Answer 1

楼主，看下面的代码，[segmentedControl addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged]可以通过监听UISegmentcontrol的:UIControlEventValueChanged事件来进行处理。[mw_shl_code=c,true]NSArray *buttonNames = [NSArray arrayWithObjects:@"Button01", @"Button02", nil];UISegmentedControl* segmentedControl = [[UISegmentedControl alloc] initWithItems:buttonNames];segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar; [segmentedControl addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged]-(void)segmentAction:(id) sender{ switch([sender selectedSegmentIndex]) { case 1: label.text=@"AAAA"; break; case 2: label.text=@"BBBB"; break; default: break; }}[/mw_shl_code]

Answer 2

[self.segmControl addTarget:self action:@selector(switchingView) forControlEvents:UIControlEventValueChanged];

- (void)switchingView
{
    switch (self.segmControl.selectedSegmentIndex) {
        case 0: {
        }
            break;
        case 1: {
        }
            break;
    }
}

监听的事件为：值改变（UIControlEventValueChanged）！
