###CoreText attributes which is supported by YYText
// YYLabel (similar to UILabel)
YYLabel *label = [YYLabel new];
label.frame = ...
label.font = ...
label.textColor = ...
label.textAlignment = ...
label.lineBreakMode = ...
label.numberOfLines = ...
label.text = ...
// YYTextView (similar to UITextView)
YYTextView *textView = [YYTextView new];
textView.frame = ...
textView.font = ...
textView.textColor = ...
textView.dataDetectorTypes = ...
textView.placeHolderText = ...
textView.placeHolderTextColor = ...
textView.delegate = ...
// 1. Create an attributed string.
NSMutableAttributedString *text = [[NSMutableAttributedString alloc] initWithString:@"Some Text, blabla..."];
// 2. Set attributes to text, you can use almost all CoreText attributes.
text.yy_font = [UIFont boldSystemFontOfSize:30];
text.yy_color = [UIColor blueColor];
[text yy_setColor:[UIColor redColor] range:NSMakeRange(0, 4)];
text.yy_lineSpacing = 10;
// 3. Set to YYLabel or YYTextView.
YYLabel *label = [YYLabel new];
label.frame = ...
label.attributedString = text;
YYTextView *textView = [YYTextView new];
textView.frame = ...
textView.attributedString = text;
You can use some convenience methods to set text highlight:
[text yy_setTextHighlightRange:range
color:[UIColor blueColor]
backgroundColor:[UIColor grayColor]
tapAction:^(UIView *containerView, NSAttributedString *text, NSRange range, CGRect rect){
NSLog(@"tap text range:...");
}];
Or set the text highlight with your custom config:
// 1. Create a 'highlight' attribute for text.
YYTextBorder *border = [YYTextBorder borderWithFillColor:[UIColor grayColor] cornerRadius:3];
YYTextHighlight *highlight = [YYTextHighlight new];
[highlight setColor:[UIColor whiteColor]];
[highlight setBackgroundBorder:highlightBorder];
highlight.tapAction = ^(UIView *containerView, NSAttributedString *text, NSRange range, CGRect rect) {
NSLog(@"tap text range:...");
// you can also set the action handler to YYLabel or YYTextView.
};
// 2. Add 'highlight' attribute to a range of text.
[attributedText yy_setTextHighlight:highlight range:highlightRange];
// 3. Set text to label or text view.
YYLabel *label = ...
label.attributedText = attributedText
YYTextView *textView = ...
textView.attributedText = ...
// 4. Receive user interactive action.
label.highlightTapAction = ^(UIView *containerView, NSAttributedString *text, NSRange range, CGRect rect) {
NSLog(@"tap text range:...");
};
label.highlightLongPressAction = ^(UIView *containerView, NSAttributedString *text, NSRange range, CGRect rect) {
NSLog(@"long press text range:...");
};

###YYText 支持的 CoreText 属性
// YYLabel (和 UILabel 用法一致)
YYLabel *label = [YYLabel new];
label.frame = ...
label.font = ...
label.textColor = ...
label.textAlignment = ...
label.lineBreakMode = ...
label.numberOfLines = ...
label.text = ...
// YYTextView (和 UITextView 用法一致)
YYTextView *textView = [YYTextView new];
textView.frame = ...
textView.font = ...
textView.textColor = ...
textView.dataDetectorTypes = ...
textView.placeHolderText = ...
textView.placeHolderTextColor = ...
textView.delegate = ...
// 1. 创建一个属性文本
NSMutableAttributedString *text = [[NSMutableAttributedString alloc] initWithString:@"Some Text, blabla..."];
// 2. 为文本设置属性
text.yy_font = [UIFont boldSystemFontOfSize:30];
text.yy_color = [UIColor blueColor];
[text yy_setColor:[UIColor redColor] range:NSMakeRange(0, 4)];
text.yy_lineSpacing = 10;
// 3. 赋值到 YYLabel 或 YYTextView
YYLabel *label = [YYLabel new];
label.frame = ...
label.attributedString = text;
YYTextView *textView = [YYTextView new];
textView.frame = ...
textView.attributedString = text;
你可以用一些已经封装好的简便方法来设置文本高亮:
[text yy_setTextHighlightRange:range
color:[UIColor blueColor]
backgroundColor:[UIColor grayColor]
tapAction:^(UIView *containerView, NSAttributedString *text, NSRange range, CGRect rect){
NSLog(@"tap text range:...");
}];
或者用更复杂的办法来调节文本高亮的细节:
// 1. 创建一个"高亮"属性,当用户点击了高亮区域的文本时,"高亮"属性会替换掉原本的属性
YYTextBorder *border = [YYTextBorder borderWithFillColor:[UIColor grayColor] cornerRadius:3];
YYTextHighlight *highlight = [YYTextHighlight new];
[highlight setColor:[UIColor whiteColor]];
[highlight setBackgroundBorder:highlightBorder];
highlight.tapAction = ^(UIView *containerView, NSAttributedString *text, NSRange range, CGRect rect) {
NSLog(@"tap text range:...");
// 你也可以把事件回调放到 YYLabel 和 YYTextView 来处理。
};
// 2. 把"高亮"属性设置到某个文本范围
[attributedText yy_setTextHighlight:highlight range:highlightRange];
// 3. 把属性文本设置到 YYLabel 或 YYTextView
YYLabel *label = ...
label.attributedText = attributedText
YYTextView *textView = ...
textView.attributedText = ...
// 4. 接受事件回调
label.highlightTapAction = ^(UIView *containerView, NSAttributedString *text, NSRange range, CGRect rect) {
NSLog(@"tap text range:...");
};
label.highlightLongPressAction = ^(UIView *containerView, NSAttributedString *text, NSRange range, CGRect rect) {
NSLog(@"long press text range:...");
};
@UITextViewDelegate
