Foundation之NSMutableString

一、NSMutableString的使用

 1 int main(int argc, const char * argv[])
 2 {
 3 
 4     @autoreleasepool {
 5         
 6         // 预先分配10个字数的存储空间
 7         NSMutableString *s1 = [NSMutableString stringWithCapacity:10];
 8         // 设置字符串内容
 9         [s1 setString:@"1234"];
10         // 追加字符串
11         [s1 appendString:@"56"];
12         [s1 appendFormat:@"age is %i", 10];
13         // 替换字符串
14         [s1 replaceCharactersInRange:[s1 rangeOfString:@"age"] withString:@"no"];
15         // 插入字符串
16         [s1 insertString:@" the " atIndex:[s1 rangeOfString:@"no"].location];
17         // 删除字符串
18         [s1 deleteCharactersInRange:[s1 rangeOfString:@"56"]];
19         NSLog(@"%@", s1);
20     
21     }
22     return 0;
23 }
