Isa discard compatibility in JSONKIT

BUG Description: Direct access to objective-c's isa is deprecated in favor of object_setClass () and object_getClass ()

Solution: In Build Settings of target, Change Build ActiveArchitecture Only to YES.

Processing result: running successfully

Other methods:

1. Change the code

Convert array-> isa = _ JKArrayClass;

Replace it with object_setClass (array, _ JKArrayClass );

Set dictionary-> isa = _ JKDictionaryClass;

Replace it with object_setClass (dictionary, _ JKDictionaryClass );

Xcode upgrade 4.6 references static library. a reports the error ld: file... not contain a (n) armv7s slice: xxx. afor architecture armv7s

Because the iPhone 5 A6 processor uses the new Armv7s architecture, XCode4.6 uses this architecture by default when creating a Project. When a third-party static library is compiled, the system prompts "ld: file... Not containa (n) armv7s slice: xxx. a for architecture armv7s "error.

Therefore, before a third-party class library is compatible with the Armv7s architecture update, we can solve the problem by using the following methods:

Method 1. The. a file involved in the upgrade is compatible with Armv7s.

Method 2: Change Build ActiveArchitecture Only to YES in Build Settings of target.

Method 3: Change $ (ARCHS_STANDARD_32_BIT) of ubuntures to armv7 in BuildSetting of XCode 4.5.

Therefore, if it is an open-source library, it is best to directly include the source code into the project, so that such a problem will not occur.
