iOS9 字符串或url的 UTF-8 编解码
您需要加密的字符串
NSString *str = @"您需要加密的字符串GG...";
编码
// 被弃用的编码方法
// NSString *encodeStr =[str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
// 替代方法实现
NSString *charactersToEscape = @"?!@#$^&%*+,:;='\"`<>()[]{}/\\| ";//此处不做更改，
NSCharacterSet *allowedCharacters = [[NSCharacterSet characterSetWithCharactersInString:charactersToEscape] invertedSet];
NSString *encodeStr = [str stringByAddingPercentEncodingWithAllowedCharacters:allowedCharacters];
NSLog(@"encodeStr___%@",encodeStr);
解码
// 被弃用的解码方法
// NSString *deCodeStr = [encodeStr stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSString *deCodeStr = encodeStr.stringByRemovingPercentEncoding;
NSLog(@"deCodeStr__%@",deCodeStr);
