有人能告诉我如何改变UISegmentedControl的字体类型和大小吗?
当前回答
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)
}
}
只需要改变数值(ofSize: 24.0)
其他回答
这里我已经更新了iOS8
[[UISegmentedControl appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:@"STHeitiSC-Medium" size:13.0], NSFontAttributeName, nil] forState:UIControlStateNormal];
以下是Swift版本的公认答案:
斯威夫特3:
let font = UIFont.systemFont(ofSize: 16)
segmentedControl.setTitleTextAttributes([NSFontAttributeName: font],
for: .normal)
斯威夫特2.2:
let font = UIFont.systemFontOfSize(16)
segmentedControl.setTitleTextAttributes([NSFontAttributeName: font],
forState: UIControlState.Normal)
丹尼尔指给我正确的路。我是这样用的-
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;
// 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];
如果您有任何疑问,请联系我。
这是为objective - c添加你的分段控件名称来代替mysegmentedcontrol
UIFont *font = [UIFont systemFontOfSize:11.0f];
NSDictionary *attributes = [NSDictionary dictionaryWithObject:font
forKey:UITextAttributeFont];
[mySegmentedcontrol setTitleTextAttributes:attributes forState:UIControlStateNormal];
希望能有所帮助
