Convert array to NSAttributedString

问题

I have a NSMutableArray composed of NSAttributedString's.

I'm trying to convert it to a single NSAttributedString separating all the NSAttributedString's with a character.

This approach is similar to the conversion of an array to a NSString with the componentsJoinedByString:@"," method but unfortunately this method doesn't exist with the NSAttributedString.

How can I convert the array? Thanks.

回答1:

I'd to the old way:

NSMutableAttributedString *attrStr = [[NSMutableAttributedString alloc] init];
NSAttributedString *jointElement = [[NSAttributedString alloc] initWithString:@","]
for (int i = 0; i < [yourArray count] -1; i ++)
{
    [attrStr appendAttributedString:[yourArray objectAtIndex:i]];
    [attrStr appendAttributedString:jointElement];
}
[attrStr appendAttributedString:[yourArray lastObject]];

回答2:

Create a result mutable attributed string and a 'spacer' character string, iterate the array and append the string from the array and the spacer to the result string (unless this is the last iteration, then don't add the spacer).
