问题 I have an POST request block in one of my functions and I want to change the value of an NSString object inside the block.

Here's a code skeleton, with relevant comments. - (void)getItemInformation:(NSString *)inputString{ //setup stuff [manager POST:@"http://foo.com/iphone_item_string/" parameters:parameters success:^

Why doesn't NSString getCharacters work in xcode?

由 本小妞迷上赌 提交于 2019-12-23 05:42:15
问题 -(void)myFunction { unichar myBuffer[5]; NSRange range = {0, 3}; NSString *string = [NSString alloc]; string = @"123"; [string getCharacters:myBuffer :range]; } Gets warning ! NSString may not respond to '-getCharacters::' then does a SIGABRT when I run it. Why?????

问题 I've been trying to figure this out for weeks and i still get nothing. I am using the ASIHTTPRequest and ive successfully sent the data to a server and now I need to get the response XML,parse it and save the elements to each labeled NSString so I can post it to the server.

NSString stringWithFormat less parameters [duplicate]

由 随声附和 提交于 2019-12-23 01:42:08
问题 This question already has an answer here : Multiple arguments in stringWithFormat: “n$” positional specifiers (1 answer) Closed 3 years ago .

Is this a bug or a

Base64 issue in NSMutableURLRequest POST message?

由 余生颓废 提交于 2019-12-22 20:01:10
问题 I'm having communcation issues between my app and the server. I'm using RNCryptor to encrypt a message, which I then base64 encode and transfer to the server in the request. This is done in both the DATA header, and within the http body as post data. I think I'm making a mistake in how I'm converting & transferring the base64 encoded message via POST.
