我有一个问题：我的 UISegmentedControl 有三个索引 0、1、2。当我选择 UISegmentedControl 的索引时，它工作正常，但我需要进行多次触摸，并且应该关注它是如何实现的。如何编程以再次点击选定的索引，它应该可以工作......
NSArray *segmentTextContent = [NSArray arrayWithObjects: allString, favoritesString,filterString, nil];
segmentedControl = [[UISegmentedControl alloc] initWithItems:segmentTextContent];
[segmentedControl setFrame:CGRectMake(60,10,200,30)];
[segmentedControl addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
//segmentedControl.momentary = YES;
segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
segmentedControl.tintColor=[UIColor colorWithRed:36/255.0 green:61/255.0 blue:103/255.0 alpha:1];
segmentedControl.selectedSegmentIndex =0;
[toolBar1 addSubview:segmentedControl];
