UISegmentedControl的常用属性和用法

1.UISegmentControl

1)先创建一个数组用来存放标题

NSArray *array = @[@"1",@"2",@"3",nil];

UISegmentedControl *segmented = [[UISegmentedControl alloc] initWithItems:array];

[segmented insertSegmentWithTitle:@"3" atIndex:3 animated:NO];

[segmented removeSegmentAtIndex:3 animated:NO];

[segmented setImage:[UIImage ImageNamed:@"2.png"] forSegmentAtIndesx:1];

[segmented setTitle:@"分组1" forSegmentAtIndex:0];

[segmented setWidth:60 fotSegmentAtIndex:0];

//UISegmented的点击事件,后面的控制事件的状态一定是valueChanged

[segmented addTarget:self action:@selector(segmentAction:) forControlEvent:UIControlEventValueChanged];

2.通常UISegmentedControl的点击事件和switch case结合使用

- (void)segmentedAction:(UISegmentedControl *)segmented {

　　switch (segmented.selectedSegmentIndex) {

　　case 0 :

self.backGroundColor = [UIColor yellowColor];

　　break;

　　default:

　　break;

}

}
