将Objective-C程序转换为Objective-C弧时，我得到了错误:
"cast of Objective-C pointer type 'NSString *' to C pointer type 'CFStringRef' (aka 'const struct __CFString *') requires a bridged cast "
代码如下:
- (NSString *)_encodeString:(NSString *)string
{
NSString *result = (NSString *)CFURLCreateStringByAddingPercentEscapes(NULL,
(CFStringRef)string, // this is line in error
NULL,
(CFStringRef)@";/?:@&=$+{}<>,",
kCFStringEncodingUTF8);
return [result autorelease];
}
什么是桥牌演员？
