NSMutableAttributedString使用

 

//    // 1
//    NSMutableAttributedString *attributed = [[NSMutableAttributedString alloc] initWithString:str];
//    [attributed addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Zapfino" size:20] range:NSMakeRange(0, str.length)];
//    [attributed addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(5, 2)];
//    label.attributedText = attributed;
//   
//    // 2
//    NSDictionary *attrDict = @{NSFontAttributeName:[UIFont fontWithName: @"Zapfino" size: 15],
//                                NSForegroundColorAttributeName:[UIColor blueColor]};
//   
//    NSMutableAttributedString *attributed2 = [[NSMutableAttributedString alloc] initWithString:str attributes:attrDict];
//    label.attributedText = attributed2;
//   
//    //打印系统中所有字体的类型名字
//    NSArray *familyNames = [UIFont familyNames];
//    for(NSString *familyName in familyNames ){
//        printf("Family: %s \n", [familyName UTF8String]);
//        NSArray *fontNames = [UIFont fontNamesForFamilyName:familyName];
//        for(NSString *fontName in fontNames) {
//            printf("\tFont: %s \n", [fontName UTF8String]);
//  
//        }
//    }
   
   
    //方式二的分段处理
    //第一段
   
//    NSString *originStr = @"家里人今天的上课了国家的路口时根据法律的空格键";
//   
//    NSDictionary *attrDict1 = @{NSFontAttributeName:[UIFont fontWithName: @"Zapfino" size: 15],
//                                 NSForegroundColorAttributeName:[UIColor blueColor] };
//    NSAttributedString *attrStr1 = [[NSAttributedString alloc] initWithString: [originStr substringWithRange: NSMakeRange(0, 4)] attributes: attrDict1];
//   
//    //第二段
//    NSDictionary *attrDict2 = @{NSFontAttributeName:[UIFont fontWithName: @"Zapfino" size: 15],
//                                 NSForegroundColorAttributeName:[UIColor redColor] };
//    NSAttributedString *attrStr2 = [[NSAttributedString alloc] initWithString: [originStr substringWithRange: NSMakeRange(4, 3)] attributes: attrDict2];
//   
//    //第三段
//    NSDictionary *attrDict3 = @{NSFontAttributeName:[UIFont fontWithName: @"Zapfino" size: 15],
//                                 NSForegroundColorAttributeName:[UIColor blackColor] };
//    NSAttributedString *attrStr3 = [[NSAttributedString alloc] initWithString:[originStr substringWithRange:NSMakeRange(7, originStr.length - 4 - 3)] attributes: attrDict3];
//    //合并
//    NSMutableAttributedString *attributedStr03 = [[NSMutableAttributedString alloc] initWithAttributedString: attrStr1];
//    [attributedStr03 appendAttributedString: attrStr2];
//    [attributedStr03 appendAttributedString: attrStr3];
//   
//    label.attributedText = attributedStr03;
   
   
   // 举例说明：
   
//    1. NSFontAttributeName
   
   
    //NSForegroundColorAttributeName 设置字体颜色，取值为 UIColor，默认为黑色
//   
//    NSDictionary *attrDict1 = @{ NSForegroundColorAttributeName: [UIColor redColor] };
//    NSDictionary *attrDict2 = @{ NSForegroundColorAttributeName: [UIColor blueColor] };
//    NSDictionary *attrDict3 = @{ NSForegroundColorAttributeName: [UIColor orangeColor] };
//   
//    label.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict1];
//    label2.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict2];
//    label3.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict3];
//   
//   
//   
////   注意：
////   
////    NSForegroundColorAttributeName设置的颜色与UILabel的textColor属性设置的颜色在地位上是相等的，谁最后赋值，最终显示的就是谁的颜色。
////   
//   
//   
////    2. NSBackgroundColorAttributeName
//   
//   
//    //NSForegroundColorAttributeName设置字体颜色，取值为 UIColor，默认为黑色
//   
//    NSDictionary *attrDict1 = @{ NSForegroundColorAttributeName: [UIColor redColor] };
//    NSDictionary *attrDict2 = @{ NSForegroundColorAttributeName: [UIColor blueColor] };
//    NSDictionary *attrDict3 = @{ NSForegroundColorAttributeName: [UIColor orangeColor] };
//   
//    label.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict1];
//    label2.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict2];
//    label3.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict3];
//   
//   
//    //NSBackgroundColorAttributeName设置字体所在区域背景的颜色，取值为UIColor，默认值为nil
//   
//    NSDictionary *attrDict4 = @{ NSBackgroundColorAttributeName: [UIColor orangeColor] };
//    NSDictionary *attrDict5 = @{ NSBackgroundColorAttributeName: [UIColor redColor] };
//    NSDictionary *attrDict6 = @{ NSBackgroundColorAttributeName: [UIColor cyanColor] };
//   
//    label1.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict4];
//    label2.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict5];
//    label3.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict6];
//   
//   
//   
////   
////   仔细观察会发现个问题，我并没有关闭 NSForegroundColorAttributeName 属性，但是在运行结果中，所有字体的颜色都变成了默认色——黑色，这说明NSForegroundColorAttributeName和 NSBackgroundColorAttributeName 的低位是相等的，跟前面介绍的 textColor 一样，哪个属性最后一次赋值，就会冲掉前面的效果，若是我们把属性代码顺序交换一下
//   
//   
//    //NSBackgroundColorAttributeName设置字体所在区域背景的颜色，取值为UIColor，默认值为nil
//   
//    NSDictionary *attrDict4 = @{ NSBackgroundColorAttributeName: [UIColor orangeColor] };
//    NSDictionary *attrDict5 = @{ NSBackgroundColorAttributeName: [UIColor redColor] };
//    NSDictionary *attrDict6 = @{ NSBackgroundColorAttributeName: [UIColor cyanColor] };
//   
//    label1.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict4];
//    label2.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict5];
//    label3.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict6];
//   
//    //NSForegroundColorAttributeName设置字体颜色，取值为 UIColor，默认为黑色
//   
//    NSDictionary *attrDict1 = @{ NSForegroundColorAttributeName: [UIColor redColor] };
//    NSDictionary *attrDict2 = @{ NSForegroundColorAttributeName: [UIColor blueColor] };
//    NSDictionary *attrDict3 = @{ NSForegroundColorAttributeName: [UIColor orangeColor] };
//   
//    label1.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict1];
//    label2.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict2];
//    label3.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict3];
//   
//   
//   
//   
////   但是textColor属性可以与NSBackgroundColorAttributeName属性叠加
//   
//   
//    label1.textColor = [UIColor greenColor];
//    label2.textColor = [UIColor yellowColor];
//    label3.textColor = [UIColor blueColor];
//   
//    //NSForegroundColorAttributeName设置字体颜色，取值为 UIColor，默认为黑色
//   
//    NSDictionary *attrDict1 = @{ NSForegroundColorAttributeName: [UIColor redColor] };
//    NSDictionary *attrDict2 = @{ NSForegroundColorAttributeName: [UIColor blueColor] };
//    NSDictionary *attrDict3 = @{ NSForegroundColorAttributeName: [UIColor orangeColor] };
//   
//    label1.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict1];
//    label2.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict2];
//    label3.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict3];
//   
//   
//    //NSBackgroundColorAttributeName设置字体所在区域背景的颜色，取值为UIColor，默认值为nil
//   
//    NSDictionary *attrDict4 = @{ NSBackgroundColorAttributeName: [UIColor orangeColor] };
//    NSDictionary *attrDict5 = @{ NSBackgroundColorAttributeName: [UIColor redColor] };
//    NSDictionary *attrDict6 = @{ NSBackgroundColorAttributeName: [UIColor cyanColor] };
//   
//    label1.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict4];
//    label2.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict5];
//    label3.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict6];
//   
//   
////   
////   虽然 textColor 在 NSFontAttributeName 之前赋值，但是由于 NSFontAttributeName 的属性效果被NSBackgroundColorAttributeName属性冲掉了，所以最终显示了 textColor 的颜色。
//   
//   
//   
////    3. NSLigatureAttributeName
//   
//    //NSLigatureAttributeName设置连体属性，取值为NSNumber对象(整数)，0表示没有连体字符，1表示使用默认的连体字符，
//    //                        2表示使用所有连体符号，默认值为 1（iOS不支持 2）
//   
//    NSString *ligatureStr = @"flush";
//   
//    NSDictionary *attrDict1 = @{ NSLigatureAttributeName: [NSNumber numberWithInt: 0],
//                                 NSFontAttributeName: [UIFont fontWithName: @"futura" size: 30] };
//    label1.attributedText = [[NSAttributedString alloc] initWithString: ligatureStr attributes: attrDict1];
//   
//    NSDictionary *attrDict2 = @{ NSLigatureAttributeName: @(1),
//                                 NSFontAttributeName: [UIFont fontWithName: @"futura" size: 30]
//                                 };
//    label2.attributedText = [[NSAttributedString alloc] initWithString: ligatureStr attributes: attrDict2];
////   由于要展示连体字符，所以将前面使用的带有中文的字符串换成 flush
////   
////    NSLigatureAttributeName的取值为NSNumber对象，所以不能直接将一个整数值赋给它，创建NSNumber对象的方法有很多，或者可以简写成 @(int)
//   
//   
//   
//   
//   
////   注意观察字母f和l之间的变化。
////   
////   感觉连写就是一个艺术字功能，当字符f和l组合使用组合符号（所谓的字形(glyph)）绘制时，看起来确实更加美观。但是并非所有的字符之间都有组合符号，事实上，只有某些字体中得某些字符的组合（如字符f和l，字符f和i等）才具有美观的组合符号。
//   
//   
//   
////    4. NSKernAttributeName
//   
//   
//    //NSKernAttributeName设定字符间距，取值为 NSNumber 对象（整数），正值间距加宽，负值间距变窄
//   
//   
//    NSDictionary *attrDict1 = @{ NSKernAttributeName: @(-3),
//                                 NSFontAttributeName: [UIFont systemFontOfSize: 20]
//                                 };
//    label1.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict1];
//   
//   
//    NSDictionary *attrDict2 = @{ NSKernAttributeName: @(0),
//                                 NSFontAttributeName: [UIFont systemFontOfSize: 20]
//                                 };
//    label2.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict2];
//   
//   
//    NSDictionary *attrDict3 = @{ NSKernAttributeName: @(10),
//                                 NSFontAttributeName: [UIFont systemFontOfSize: 20]
//                                 };
//    label3.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict3];
//   
//   
//   
//   
//   
//   
////    5. NSStrikethroughStyleAttributeName
//   
//   
//    //NSStrikethroughStyleAttributeName设置删除线，取值为 NSNumber 对象（整数），枚举常量 NSUnderlineStyle中的值
//    // NSUnderlineStyleNone  不设置删除线
//    // NSUnderlineStyleSingle设置删除线为细单实线
//    // NSUnderlineStyleThick 设置删除线为粗单实线
//    // NSUnderlineStyleDouble设置删除线为细双实线
//   
//   
//    NSDictionary *attrDict1 = @{ NSStrikethroughStyleAttributeName: @(NSUnderlineStyleSingle),
//                                 NSFontAttributeName: [UIFont systemFontOfSize:20] };
//    label1.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict1];
//   
//   
//    NSDictionary *attrDict2 = @{ NSStrikethroughStyleAttributeName: @(NSUnderlineStyleThick),
//                                 NSFontAttributeName: [UIFont systemFontOfSize:20] };
//    label2.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict2];
//   
//   
//    NSDictionary *attrDict3 = @{ NSStrikethroughStyleAttributeName: @(NSUnderlineStyleDouble),
//                                 NSFontAttributeName: [UIFont systemFontOfSize:20] };
//    label3.attributedText = [[NSAttributedString alloc] initWithString: originStr attributes: attrDict3];
////   注意：
////   
////   虽然使用了枚举常量，但是枚举常量的本质仍为整数，所以同样必须先转化为 NSNumber 才能使用
////   
////   删除线和下划线使用相同的枚举常量作为其属性值
////   
////   目前iOS中只有上面列出的4中效果，虽然我们能够在头文件中发现其他更多的取值，但是使用后没有任何效果
//   
//   
//   
//   
//   
//   
////   可以看出，中文和英文删除线的位置有所不同
////   
////   另外，删除线属性取值除了上面的4种外，其实还可以取其他整数值，有兴趣的可以自行试验，取值为0 - 7时，效果为单实线，随着值得增加，单实线逐渐变粗，取值为9 - 15时，效果为双实线，取值越大，双实线越粗。
