我有一门NSString的分类课.
@implementation NSString (URLEncode)
- (NSString *)URLEncodedString
{
__autoreleasing NSString *encodedString;
NSString *originalString = (NSString *)self;
encodedString = (__bridge_transfer NSString * )
CFURLCreateStringByAddingPercentEscapes(NULL,
(__bridge CFStringRef)originalString,
NULL,
(CFStringRef)@"!*'();:@&=+$,/?%#[]",
kCFStringEncodingUTF8);
return encodedString;
}
我是否为ARC和新LLVM使用了正确的桥接传输？
原始代码:
- (NSString *)URLEncodedString
NSString *encodedString = (NSString *)CFURLCreateStringByAddingPercentEscapes(NULL,
(CFStringRef)self,
NULL,
(CFStringRef)@"!*'();:@&=+$,/?%#[]",
kCFStringEncodingUTF8);
return [encodedString autorelease];
}
