谁能告诉我如何更改字体的类型和大小 UISegmentedControl
?
Answers:
我遇到了同样的问题。此代码设置整个分段控件的字体大小。设置字体类型可能会类似。请注意,这仅适用于iOS5 +
对象C:
UIFont *font = [UIFont boldSystemFontOfSize:12.0f];
NSDictionary *attributes = [NSDictionary dictionaryWithObject:font
forKey:NSFontAttributeName];
[segmentedControl setTitleTextAttributes:attributes
forState:UIControlStateNormal];
编辑:UITextAttributeFont
已弃用- NSFontAttributeName
改为使用。
编辑#2:对于Swift 4 NSFontAttributeName
已更改为NSAttributedStringKey.font
。
迅捷5:
let font = UIFont.systemFont(ofSize: 16)
segmentedControl.setTitleTextAttributes([NSAttributedString.Key.font: font], for: .normal)
斯威夫特4:
let font = UIFont.systemFont(ofSize: 16)
segmentedControl.setTitleTextAttributes([NSAttributedStringKey.font: font],
for: .normal)
迅捷3:
let font = UIFont.systemFont(ofSize: 16)
segmentedControl.setTitleTextAttributes([NSFontAttributeName: font],
for: .normal)
Swift 2.2:
let font = UIFont.systemFontOfSize(16)
segmentedControl.setTitleTextAttributes([NSFontAttributeName: font],
forState: UIControlState.Normal)
感谢@ audrey-gordeev的Swift实现
[mySegmentedControl setTintColor:onColor forTag:kTagOnState];
和a [mySegmentedControl setTintColor:offColor forTag:kTagOffState];
然后应用, [mySegmentedControl setTitleTextAttributes:attributes forState:UIControlStateNormal];
那么我刚刚设置的颜色就会消失。
NSDictionary *attributes = @{NSFontAttributeName: [UIFont boldsystemFontOfSize:12.0f]};
boldSystemFontOfSize:
(系统的资本S)
在iOS 5.0及更高版本中使用外观API:
[[UISegmentedControl appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:@"STHeitiSC-Medium" size:13.0], UITextAttributeFont, nil] forState:UIControlStateNormal];

UITextAttributeFont
已折旧-请NSFontAttributeName
改用。
UISegmentedControl
的字体。
这是已接受答案的Swift版本:
迅捷3:
let font = UIFont.systemFont(ofSize: 16)
segmentedControl.setTitleTextAttributes([NSFontAttributeName: font],
for: .normal)
Swift 2.2:
let font = UIFont.systemFontOfSize(16)
segmentedControl.setTitleTextAttributes([NSFontAttributeName: font],
forState: UIControlState.Normal)
另一种选择是将变换应用于控件。但是,它将缩小包括控件边界在内的所有内容。
segmentedControl.transform = CGAffineTransformMakeScale(.6f, .6f);
迅捷风格:
UISegmentedControl.appearance().setTitleTextAttributes(NSDictionary(objects: [UIFont.systemFontOfSize(14.0)], forKeys: [NSFontAttributeName]), forState: UIControlState.Normal)
[NSFontAttributeName: font]
XCode 8.1,Swift 3
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
UISegmentedControl.appearance().setTitleTextAttributes(NSDictionary(objects: [UIFont.systemFont(ofSize: 24.0)],
forKeys: [NSFontAttributeName as NSCopying]) as? [AnyHashable : Any],
for: UIControlState.normal)
}
}
只需更改数字值 (ofSize: 24.0)
// Set font-size and font-femily the way you want
UIFont *objFont = [UIFont fontWithName:@"DroidSans" size:18.0f];
// Add font object to Dictionary
NSDictionary *dictAttributes = [NSDictionary dictionaryWithObject:objFont forKey:NSFontAttributeName];
// Set dictionary to the titleTextAttributes
[yourSegment setTitleTextAttributes:dictAttributes forState:UIControlStateNormal];
如有任何疑问,请与我联系。
nil
值。
斯威夫特4
let font = UIFont.systemFont(ofSize: 16)
UISegmentedControl.setTitleTextAttributes([NSFontAttributeName: font], for: .normal)
Instance member 'setTitleTextAttributes' cannot be used on type 'UISegmentedControl'; did you mean to use a value of this type instead?
iOS13 / Swift5
丹尼尔指出我正确的方法。我这样使用它-
float scaleFactor = 0.8f;
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc]
initWithFrame:CGRectMake(10, 70, 300/scaleFactor,35)];
[segmentedControl insertSegmentWithTitle:@"..." atIndex:0 animated:NO];
[segmentedControl insertSegmentWithTitle:@"..." atIndex:1 animated:NO];
[segmentedControl insertSegmentWithTitle:@"..." atIndex:2 animated:NO];
segmentedControl.transform = CGAffineTransformMakeScale(scaleFactor, 1);
CGPoint segmentedControlCenter = segmentedControl.center;
segmentedControlCenter.x = self.center.x;
segmentedControl.center = segmentedControlCenter;
UISegmentedControl
用于设置字体大小的扩展名。
extension UISegmentedControl {
@available(iOS 8.2, *)
func setFontSize(fontSize: CGFloat) {
let normalTextAttributes: [NSObject : AnyObject]!
if #available(iOS 9.0, *) {
normalTextAttributes = [
NSFontAttributeName: UIFont.monospacedDigitSystemFontOfSize(fontSize, weight: UIFontWeightRegular)
]
} else {
normalTextAttributes = [
NSFontAttributeName: UIFont.systemFontOfSize(fontSize, weight: UIFontWeightRegular)
]
}
self.setTitleTextAttributes(normalTextAttributes, forState: .Normal)
}
}
UISegmentedControl.appearance().setTitleTextAttributes(NSDictionary(objects: [UIFont.systemFont(ofSize: 16.0)],
forKeys: [kCTFontAttributeName as! NSCopying]) as? [AnyHashable : Any],
for: UIControlState.normal)
您可以通过递归检查从UISegmentedControl开始的每个视图来获得UILabel的实际字体。我不知道这是否是最好的方法,但是它有效。
@interface tmpSegmentedControlTextViewController : UIViewController {
}
@property (nonatomic, assign) IBOutlet UISegmentedControl * theControl;
@end
@implementation tmpSegmentedControlTextViewController
@synthesize theControl; // UISegmentedControl
- (void)viewDidLoad {
[self printControl:[self theControl]];
[super viewDidLoad];
}
- (void) printControl:(UIView *) view {
NSArray * views = [view subviews];
NSInteger idx,idxMax;
for (idx = 0, idxMax = views.count; idx < idxMax; idx++) {
UIView * thisView = [views objectAtIndex:idx];
UILabel * tmpLabel = (UILabel *) thisView;
if ([tmpLabel respondsToSelector:@selector(text)]) {
NSLog(@"TEXT for view %d: %@",idx,tmpLabel.text);
[tmpLabel setTextColor:[UIColor blackColor]];
}
if (thisView.subviews.count) {
NSLog(@"View has subviews");
[self printControl:thisView];
}
}
}
@end
在上面的代码中,我只是设置UILabel的文本颜色,但是我想也可以抓取或设置font属性。
这是为目标c添加分段控件名称代替mysegmentedcontrol
UIFont *font = [UIFont systemFontOfSize:11.0f];
NSDictionary *attributes = [NSDictionary dictionaryWithObject:font
forKey:UITextAttributeFont];
[mySegmentedcontrol setTitleTextAttributes:attributes forState:UIControlStateNormal];
希望能帮助到你
