IOS 8 中 MWPhotoBrowser 的方法声明缺少上下文

Question

在迁移到 IOS 8 和 XCODE 6 后，我遇到了 MWPhoto 库的问题。错误发生在 PSTCollectionView 类中。我想知道为什么它返回我Missing context for method declaration 错误。您可以在下面找到错误的代码和图像。

#import <objc/runtime.h>
- (NSMethodSignature *)methodSignatureForSelector:(SEL)selector {
    NSMethodSignature *signature = [super methodSignatureForSelector:selector];
    if (!signature) {
        NSString *selString = NSStringFromSelector(selector);
        if ([selString hasPrefix:@"_"]) {
            SEL cleanedSelector = NSSelectorFromString([selString substringFromIndex:1]);
            signature = [super methodSignatureForSelector:cleanedSelector];
        }
    }
    return signature;
}

- (void)forwardInvocation:(NSInvocation *)invocation {
    NSString *selString = NSStringFromSelector([invocation selector]);
    if ([selString hasPrefix:@"_"]) {
        SEL cleanedSelector = NSSelectorFromString([selString substringFromIndex:1]);
        if ([self respondsToSelector:cleanedSelector]) {
            invocation.selector = cleanedSelector;
            [invocation invokeWithTarget:self];
        }
    }else {
        [super forwardInvocation:invocation];
    }
}
