你知道我怎样才能将浮点值转换为nsstring值,因为我的代码存在错误.

我的代码:

- (float)percent:(float)a :(float)b{
    return a / b * 100;
}

- (void)objectLoader:(RKObjectLoader*)objectLoader didLoadObjects:(NSArray*)objects {
  // ....   

    float tx_nb_demande_portabilite = [self percent: [(NSNumber*) [stat nb_demande_portabilite] floatValue] :[(NSNumber*) [stat nb_users] floatValue]];
    NSString *tx_nb_demande_portabilite_st = [NSString stringWithFormat:@"%@", tx_nb_demande_portabilite];
//....
}

错误 :

EXC_BAD ACCESS for NSString *tx_nb_demande_portabilite_st = [NSString stringWithFormat:@"%@", tx_nb_demande_portabilite];

谢谢您的帮助.

我的构建错误.Xcode返回

Undefined symbols for architecture i386:
  "_main", referenced from:
      start in crt1.10.6.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

你知道如何使用-v启动构建来查看调用吗？
