如何以编程方式更改UISegmentedControl标题？你能帮我吗？

@synthesize filterControl; //UISegmentedControl

- (void)viewDidLoad
{
    [super viewDidLoad];

    filterControl = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:@"ALL",@"PROFIT",@"LOSS", nil]]; //not working

}

Answer 1

只需使用

-setTitle:(NSString*)title forSegmentAtIndex:(NSUInteger)index;

Answer 2

您可以直接更改sectionTitles。

经常错过的是致电setNeedsDisplay()。

Swift中的代码：

segmentedControl.sectionTitles = ["All", "Profit", "Loss"]
segmentedControl.setNeedsDisplay()

Answer 3

 [filterControl setTitle:@"All" forSegmentAtIndex:0];
 [filterControl setTitle:@"PROFIT" forSegmentAtIndex:1];
 [filterControl  setTitle:@"LOSS" forSegmentAtIndex:2];

试试这个。希望它对你有用。

Answer 4

已更新：

使用下面的简单代码以编程方式设置UISegmentControl标题；

- (void)viewDidLoad {

    [super viewDidLoad];

     [self.segmentControl setTitle:@"Love It" forSegmentAtIndex:0];
     [self.segmentControl setTitle:@"Hate It" forSegmentAtIndex:1];        
     [self.segmentControl setTitle:@"Ehh" forSegmentAtIndex:2];
}

//注意：此处self.segmentControl = filterControl

Swift5

要更改 HmSegment 控件的标题字体和大小，您必须使用 titleTextAttributes 属性。

segmentedControl.titleTextAttributes = [NSAttributedString.Key.font: UIFont(name: "Poppins-Medium", size: 16.0) as Any]
segmentedControl.setNeedsDisplay()

Answer 6

您是否已将filterControl作为子视图添加到其superview中？
