Remove first byte from NSMutableData
NSMutableData *requestData = (NSMutableData*)[request responseData];
returns
"[{JSON_STRING}]"
so I want to strip out the "[" / "]" without converting to NSString and then back to NSData. The easiest way to开发者_JS百科 do this is to strip out the first and last byte.
[requestData setLength:[requestData length]-1];
removes the last byte.
How to remove the first byte? I tried the solution below, but doesn't work..
NSRange range = {0, 1};
[requestData resetBytesInRange:range];
Here's how you strip the first byte off an NSMutableData:
NSRange range = NSMakeRange(0, 1);
[requestData replaceBytesInRange:range withBytes:NULL length:0];
You could use
NSRange range = NSMakeRange(1, [requestData length] - 2);
NSData *refinedData = [requestData subdataWithRange:range];
This should take care of both the first and last character.
