ios - 以下哪项将设置UISegmentedControl的字体？

Question

UIFont font = [UIFont boldSystemFontOfSize: 12.0f];
NSDictionary attributes = [NSDictionary dictionaryWithObject: font forKey: UITextAttributeFont];
[segmentedControl setTitleTextAttributes: attributes forState: UIControlStateNormal];

[[UISegmentedControl appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:@"STHeitiSC-Medium" size:13.0], UITextAttributeFont, nil] forState:UIControlStateNormal];

segmentedControl.transform = CGAffineTransformMakeScale(.6f, .6f);

这些都不是。

Answer 1

UIFont font = [UIFont boldSystemFontOfSize: 12.0f];
NSDictionary attributes = [NSDictionary dictionaryWithObject: font forKey: UITextAttributeFont];
[segmentedControl setTitleTextAttributes: attributes forState: UIControlStateNormal];

上面的代码将更改一个特定segmentControl的字体，而下面的代码将更改您应用中所有segmentControl的字体。

[[UISegmentedControl appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:@"STHeitiSC-Medium" size:13.0], UITextAttributeFont, nil] forState:UIControlStateNormal];

而此代码 segmentedControl.transform = CGAffineTransformMakeScale(.6f, .6f);只会缩小您的segmentcontrol

注意:

只需将废弃的 UITextAttributeFont替换为 NSFontAttributeName即可工作，而不会发出警告。
