iphone - 为什么 SegmentedControl 以相反的顺序打开？

Question

 - (void)viewDidLoad
    {
   [super viewDidLoad];

    [self.segmentedControl removeAllSegments];
    s = 0;
    for (NSDictionary *dictionary in self.top.segments) {
        [_segmentedControl insertSegmentWithTitle:dictionary [@"sTitle"] atIndex:s animated:NO];
        self.bioTextView.text = [NSString stringWithFormat:@"%@", dictionary [@"sData"]];
    }}

我的segmentedControl 以相反的顺序启动。请知道的人告诉我如何解决这个问题？请参阅视频中的示例: http://youtu.be/YSYFxvb7fpA

Answer 1

您始终在索引 0 处(即开头)添加新段。

所以你会这样:

A

B>A

C>B>A

您需要在末尾添加。

使用:

s = 0;
for (NSDictionary *dictionary in self.top.segments) {
    [_segmentedControl insertSegmentWithTitle:dictionary [@"sTitle"] atIndex:s animated:NO];
    self.bioTextView.text = [NSString stringWithFormat:@"%@", dictionary [@"sData"]];
    s++;
}
