iphone - ios - 如何在字符串中动态调用另一个类的方法？

Question

我是 iPhone 开发的新手，我想调用 String 中另一个类的方法

在登录成功.m

- (void)Post:(NSString *)url AndSecondStr:(NSString *)postData AndThirdStr:(NSString *)contentType

在寄存器.m

LoginSuccess *loginViewInstance =  [[LoginSuccess alloc]initWithNibName:@"LoginSuccess" bundle:nil];
[loginViewInstance Post:TxtEmailId AndSecondStr:TxtUserName AndThirdStr:serializeObject];

上面的方法被执行了，但是我想在String中调用那个方法，比如

NSString *result = [loginViewInstance Post:TxtEmailId AndSecondStr:TxtUserName AndThirdStr:serializeObject];

有什么想法吗？提前致谢。

替换

- (void)Post:(NSString *)url AndSecondStr:(NSString *)postData AndThirdStr:(NSString *)contentType

与

- (NSString *)Post:(NSString *)url AndSecondStr:(NSString *)postData AndThirdStr:(NSString *)contentType
{
    NSString *str;
    str = someValue;
    return str;
}
