iphone - 有没有办法使 UISegmentedControl 按钮大小不同？

Question

我有一个包含 2 个项目的 UISegmentedControl。

有没有办法让左边的item比右边的item大一点？

UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:symbol,@"+", nil]];
        [segmentedControl addTarget:self action:@selector(segmentedControlChanged:)forControlEvents:UIControlEventValueChanged];
        [segmentedControl setWidth:45 forSegmentAtIndex:0];
        [segmentedControl setWidth:20 forSegmentAtIndex:1];
        segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
        segmentedControl.frame = CGRectMake(0,0,300,30);
        segmentedControl.momentary = NO;
        [segmentedControl setSelectedSegmentIndex:0];

        self.navigationItem.titleView = segmentedControl;

不起作用。

是的，你可以这样做:-

    [*yoursegmentcontrolobjectname* setWidth:45 forSegmentAtIndex:0];
    [*yoursegmentcontrolobjectname* setWidth:15 forSegmentAtIndex:1];   

UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:symbol,@"+", nil]];
        [segmentedControl addTarget:self action:@selector(segmentedControlChanged:)forControlEvents:UIControlEventValueChanged];
        segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
        segmentedControl.frame = CGRectMake(0,0,300,30);
        segmentedControl.momentary = NO;
        [segmentedControl setSelectedSegmentIndex:0];

        self.navigationItem.titleView = segmentedControl;

现在添加这两行就可以了

        [segmentedControl setWidth:45 forSegmentAtIndex:0];
        [segmentedControl setWidth:20 forSegmentAtIndex:1];
