本文主要介绍IOS中对Url进行编码和解码示例,具体如下:
1.非ARC模式下
+ (NSString *)encodeToPercentEscapeString: (NSString *) input { // Encode all the reserved characters, per RFC 3986 // () NSString *outputStr = (NSString *)CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault,(CFStringRef)input,NULL,(CFStringRef)@"!*'();:@&=+$,/?%#[]", kCFStringEncodingUTF8); return outputStr; } + (NSString *)decodeFromPercentEscapeString: (NSString *) input { NSMutableString *outputStr = [NSMutableString stringWithString:input]; [outputStr replaceOccurrencesOfString:@"+" withString:@" " options:NSLiteralSearch range:NSMakeRange(0, [outputStr length])]; return [outputStr stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
2. ARC模式下
- (NSString *)encodeToPercentEscapeString: (NSString *) input{ NSString* outputStr = (__bridge NSString *)CFURLCreateStringByAddingPercentEscapes( NULL, /* allocator */ (__bridge CFStringRef)input, NULL, /* charactersToLeaveUnescaped */ (CFStringRef)@"!*'();:@&=+$,/?%#[]", kCFStringEncodingUTF8); return outputStr;}- (NSString *)decodeFromPercentEscapeString: (NSString *) input {NSMutableString *outputStr = [NSMutableString stringWithString:input];[outputStr replaceOccurrencesOfString:@"+"withString:@" "options:NSLiteralSearchrange:NSMakeRange(0, [outputStr length])];return [outputStr stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];}
