//字符串转变为数组1
NSMutableString * str=[[NSMutableString alloc]initWithFormat:@"1,1,1,1,1,1"];
//字符串转变为数组2
NSMutableArray * arrwww.hbbz08.com ay=[NSMutableArray arrayWithArray:[str componentsSeparatedByString:@","]];
//替换数组中的某个值
[array replaceObjectAtIndex:4 withObject:@"2"];
//把数组转换成字符串
NSString *ns=[array componentsJoinedByString:@","];
