数组中字符串中的不同字体样式

假设我有这个:

self.dictionary = [NSMutableArray arrayWithObjects:
                           @"blah",
                           @"blah",
                           @"blah (blah)",
                           @"blah",
                           @"blah",
                           nil];

在第三个对象中,我希望第一个“blah”具有更大的字体大小和黑色字体颜色。但是,我希望括号中的第二个“blah”具有更小的尺寸和灰色。我该怎么做呢?它甚至可能吗?

您想使用NSMutableAttributedString

您只需连接所有字符串和每个子字符串,找出您想要的属性,而不是调用- setAttributes:range:

NSString不允许您拥有特定的样式。如果您的字符串需要具有样式/属性,则必须使用NSAttributedString。

现在只存储NSString个对象。 NSString没有附加任何字体。如果您想保留字体信息,可以查看NSAttributedString课程 - https://developer.apple.com/Library/ios/documentation/Cocoa/Reference/Foundation/Classes/NSAttributedString_Class/index.html

所以你的代码看起来像是:

self.items = @[
[[NSAttributedString alloc] initWithString: @"bla" attributes: @{
    NSFontAttributeName: [UIFont systemFontOfSize: 12.0],
    NSForegroundColorAttributeName: [UIColor blackColor]
}],
[[NSAttributedString alloc] initWithString: @"bla" attributes: @{
    NSFontAttributeName: [UIFont systemFontOfSize: 14.0],
    NSForegroundColorAttributeName: [UIColor grayColor]
}]
];

尝试以下代码: -

NSArray *yourArr= @[@"blah",
                       @"blah",
                       @"blah (blah)",
                       @"blah",
                       @"blah"];


    for (NSString *word in yourArr)
    {
        if ([word isEqualToString:@"blah (blah)"])
        {

            [yourAtt appendAttributedString:[[NSAttributedString  alloc]initWithString:[word componentsSeparatedByString:@" "][0] attributes:@{NSFontAttributeName:[NSFont boldSystemFontOfSize:18]}]];
            [yourAtt appendAttributedString:[[NSAttributedString alloc]initWithString:@" "]];
            [yourAtt appendAttributedString:[[NSAttributedString  alloc]initWithString:[word componentsSeparatedByString:@" "][1] attributes:@{NSFontAttributeName:[NSFont boldSystemFontOfSize:14],NSForegroundColorAttributeName:[NSColor grayColor]}]];
        }
        else
        {
            [yourAtt appendAttributedString:[[NSAttributedString alloc]initWithString:word]];
        }
        [yourAtt appendAttributedString:[[NSAttributedString alloc]initWithString:@",\n"]];

    }
    self.yourAttStr=yourAtt;
