NSMutableAttributedString  需求NSMutableAttributedString的初级学习和进阶

大兄弟，这个行不行？求赐教

1 // initWithString:  
2 NSAttributedString *attributedString_str = [[NSAttributedString alloc] initWithString:@"attributedString"];  
3 NSLog(@"%@", attributedString_str);  
4 // textView.attributedText = attributedString_str;  
5   
6   
7 // initWithAttributedString:  
8 NSAttributedString *attributedString_atts = [[NSAttributedString alloc] initWithAttributedString:attributedString_str];
