如何更改UISegmentedControl的字体颜色 [英] How to change font color of UISegmentedControl

问题描述

我尝试将 UISegmentedControl （适用于iOS 4。*）的字体颜色从白色更改为黑色。

I try to change font color from white to black for UISegmentedControl (for iOS 4.*)

UISegmentedControl *button = [[[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:itemTitle, nil]] autorelease];
button.momentary = YES;
button.segmentedControlStyle = UISegmentedControlStyleBar;
button.tintColor = [UIColor redColor];      
for (id segment in [button subviews]) {
    for (id label in [segment subviews]) {
        if ([label isKindOfClass:[UILabel class]]) {
            UILabel *titleLabel = (UILabel *) label;
            [titleLabel setTextColor:[UIColor blackColor]];
        }
    }
}
UIBarButtonItem *barButtonItem = [[[UIBarButtonItem alloc] initWithCustomView:button] autorelease];

但文字颜色不变。我应该为 UISegmentedControl 更改文字颜色做什么？

But text color does not changed. What I should do for change text color for UISegmentedControl?

推荐答案

iOS 5.0及以上版本很简单：

In iOS 5.0 and above it's very simple:

NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:
                            [UIFont boldSystemFontOfSize:17], UITextAttributeFont,
                            [UIColor blackColor], UITextAttributeTextColor,
                            nil];
[_segmentedControl setTitleTextAttributes:attributes forState:UIControlStateNormal];
NSDictionary *highlightedAttributes = [NSDictionary dictionaryWithObject:[UIColor whiteColor] forKey:UITextAttributeTextColor];
[_segmentedControl setTitleTextAttributes:highlightedAttributes forState:UIControlStateHighlighted];
