UICKeyChainStore

在使用UICKeyChainStore类库的时候 要添加Security.framework

默认的UICKeyChainStore is not ARC compatible,so i do some change by myself.

一种错误是 Implicit conversion of C pointer type 'CFTypeRef' (aka 'const void *') to Objective-C pointer type 'id' requires a bridged cast

这个可以通过默认的解决方法---添加__bridge 来解决

另一个错误是 Error: Cast of an indirect pointer to an Objective-C pointer to 'CFTypeRef ' (aka 'const void *') is disallowed with ARC

在UICKeyChainStore.m中有两处有这个错误 一个是80几行处 一个是280几行处 在网上找到了解决方法 连接如下

http://stackoverflow.com/questions/7822892/pointer-casting-with-arc

80行处修改后为

CFDataRef resultRef;

    OSStatus status = SecItemCopyMatching((__bridge CFDictionaryRef)query,

                                          (CFTypeRef *)&resultRef);

    NSData* data = (__bridge_transfer NSData*)resultRef;

280行处修改后为

NSMutableDictionary *result = nil;

        CFDataRef resultRef;

        OSStatus status = SecItemCopyMatching((__bridge CFDictionaryRef)query, (CFTypeRef *)&resultRef);

 

got it 

now we can use UICKeyChainStore when Objective-C Automatic Reference Counting is yes.
