将void函数传递给目标C中的字符串

如果您的 返回类型为 。要从函数中获取字符串,需要进行以下更改:

-(NSString *)yourFuncation{
             // Do your all stuff which you wanted to
               return FINAL_STRING;
    }

-(NSString *)checkPara{

    NSUserDefaults *successDefaults = [NSUserDefaults standardUserDefaults];
    NSString *success= [successDefaults valueForKey:@"Success"];
    if ([success isEqual:@"Success"]){

        NSUserDefaults *successDefaults = [NSUserDefaults standardUserDefaults];
        _name.text=[successDefaults valueForKey:@"name"];
        _email.text=[successDefaults valueForKey:@"email"];
        phones=[successDefaults valueForKey:@"number"];

        flooring=_floor;
        property=_propfor;

        NSString *phone = [NSString stringWithFormat:@"%@%@%@",_code.text,_mobile.text,_number1.text];
        NSLog(@"%@",phone);

        NSLog(@"GGGG %@",flooring);
        NSLog(@"HHHH %@",property);

        NSLog(@"%@",timestamp6);

        return parameter1;
    }


}

您可以这样调用此函数:

NSString *parameter =  [self checkPara];

参数 对象然后将其发送到服务器。

Parameter = [self checkPara];

-(NSString*)checkPara{
       NSString * parameter1;
       if (){
           //Your code
           parameter1 = //
       }
       else{
           //Your code
           parameter1 = //
       }

return parameter1
}
