在 Objective-C 中构建 URL [英] Building up a URL in Objective-C

问题描述

我想向不同的服务器发出请求我只想在文本字段中填写 url 或 ip 地址.我构建了不同的解决方案，但它们都失败了.我想我很接近这个.

I want to make a request to diffrent servers I only want to fill in the url or ip address in a textfield. I build different solutions but they all faild. I think with this one i'm close.

这是我目前构建的:

NSString *part0 = @"http://";
NSString *part1 = [NSString stringWithFormat:@"%@" , _serveradres.text ];
NSString *part2 = @"/API/";
NSString *compURL = [NSString stringWithFormat:@"%@" , part0 , part1 , part2 ];

NSURL *url = [NSURL URLWithString:compURL];



ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];

只是地址不一样，api都在同一个地方.

Only the address is diffrent, the api's are all ways on the same place.

稍后我想做一个可以选择http或https的开关

Later on i want to make a switch that can choose http or https

推荐答案

你应该改变这个:

NSString *compURL = [NSString stringWithFormat:@"%@" , part0 , part1 , part2 ];

为此:

NSString *compURL = [NSString stringWithFormat:@"%@%@%@" , part0 , part1 , part2 ];

因为现在您的 compURL 将只是 http://

Because now your compURL would be just http://
