ios - 如何使用分段控制来交换 Map 类型？

Question

我希望有人帮助我找到解决方案，如何将分段映射类型（标准、卫星、混合）添加或连接到我的主视图控制器。

Answer 1

试试这个

- (void)viewDidLoad
{
      segControl = [[UISegmentedControl alloc]initWithItems:[NSArray arrayWithObjects: @"One", @"Two", @"Three", nil]];
      [segControl addTarget:self action:@selector(indexDidChangeForSegmentedControl:) forControlEvents:UIControlEventValueChanged];
      [segControl setFrame:CGRectMake(50,20,200,44)];//set frame which you want
      [self.view addSubview:segControl];
}

- (void)indexDidChangeForSegmentedControl:(UISegmentedControl *)aSegmentedControl {
    switch (aSegmentedControl.selectedSegmentIndex) {
            case 0:
                map.mapType = MKMapTypeStandard;
                break;
            case 1:
                map.mapType = MKMapTypeSatellite;
                break;
            case 2:
                map.mapType = MKMapTypeHybrid;
                break;

            default:
                break;
        }
}
