ios - XCode iOS 用 + 替换空格

Question

需要帮助替换文本字段条目中的空格以发布到 GET

我当前的代码:

    NSString* urlString = [NSString stringWithFormat:@"http://server.com/ios/add.php?user=iPhone+App&message=%@", messageBox.text];
NSURL *add = [NSURL URLWithString:urlString];

[messageView loadRequest:[NSURLRequest requestWithURL:add]];

但是我尝试过

NSString *finalAdd = [add stringByReplacingOccurrencesOfString:@" " withString:@"+"];

Answer 1

您应该转义参数

NSString* urlString = [NSString stringWithFormat:@"http://server.com/ios/add.php?user=iPhone+App&message=%@", [messageBox.text stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL *add = [NSURL URLWithString:urlString];
