xcode 7类型参数不能应用于非参数化类

Question

我今天在我的xcode项目中遇到了这个错误...我以前从来没有得到它.自上次成功构建以来我所做的唯一改变是我导入了iAD框架(我在今天早上尝试进行新构建之前做了这个,所以我不确定它是否与它有任何关系.我尽管如此.)所有问题都与NSSet/NSArray/NSDictionary有关,并且都包含在UIKit的UIEvent和CoreImage的CIImage中.如果有人知道这里可能会发生什么,我会很感激输入.

编辑:我忘了提到具体的错误.他们来了:

"类型参数不能应用于非参数化类'NSSet'",

"类型参数可以应用于非参数化类'NSArray'",

"类型参数可以应用于非参数化类'NSDictionary'"

编辑2:我没有意识到应用程序商店自动将xcode从6.4更新到7.0,所以我改为标题以反映正确的xcode版本.

这是UIEvent.h中发生的地方(第50,51,52,53,56,59行):

- (nullable NSSet <UITouch *> *)allTouches;
- (nullable NSSet <UITouch *> *)touchesForWindow:(UIWindow *)window;
- (nullable NSSet <UITouch *> *)touchesForView:(UIView *)view;
- (nullable NSSet <UITouch *> *)touchesForGestureRecognizer:        (UIGestureRecognizer *)gesture NS_AVAILABLE_IOS(3_2);

// An array of auxiliary UITouch’s for the touch events that did not get delivered for a given main touch. This also includes an auxiliary version of the main touch itself.
- (nullable NSArray <UITouch *> *)coalescedTouchesForTouch:(UITouch *)touch NS_AVAILABLE_IOS(9_0);

// An array of auxiliary UITouch’s for touch events that are predicted to occur for a given main touch. These predictions may not exactly match the real behavior of the touch as it moves, so they should be interpreted as an estimate.

这是UIResponder.h中发生的地方(第31-34行):

// Generally, all responders which do custom touch handling should override all four of these methods.
// Your responder will receive either touchesEnded:withEvent: or touchesCancelled:withEvent: for each
// touch it is handling (those touches it received in touchesBegan:withEvent:).
// *** You must handle cancelled touches to ensure correct behavior in your application.  Failure to
// do so is very likely to lead to incorrect behavior or crashes.
- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(nullable UIEvent *)event;
- (void)touchesMoved:(NSSet<UITouch *> *)touches withEvent:(nullable UIEvent *)event;
- (void)touchesEnded:(NSSet<UITouch *> *)touches withEvent:(nullable UIEvent *)event;
- (void)touchesCancelled:(nullable NSSet<UITouch *> *)touches withEvent:(nullable UIEvent *)event;

也发生在UIREsponder.h(第79行):

@interface UIResponder (UIResponderKeyCommands)
@property (nullable,nonatomic,readonly) NSArray<UIKeyCommand *>     *keyCommands NS_AVAILABLE_IOS(7_0); // returns an array of UIKeyCommand objects<
@end

这是它在CIImage.h第97行和第102行中发生的地方:

/* Creates a new image from the contents of 'image'. */
+ (CIImage *)imageWithCGImage:(CGImageRef)image;
+ (CIImage *)imageWithCGImage:(CGImageRef)image
                  options:(nullable CI_DICTIONARY(NSString*,id) *)options;

/* Creates a new image from the contents of 'layer'. */
+ (CIImage *)imageWithCGLayer:(CGLayerRef)layer NS_DEPRECATED_MAC(10_4,10_11);
+ (CIImage *)imageWithCGLayer:(CGLayerRef)layer
                  options:(nullable CI_DICTIONARY(NSString*,id) *)options NS_DEPRECATED_MAC(10_4,10_11);

我重新审视了这个问题，似乎其他人已经在不同的线程和 github 上解决了这个问题。

问题是我项目中包含的 Parse/Bolts 框架已经过时，并且我将它们保存在项目本地。我的项目中的版本与 xcode 7 冲突。

删除所有本地副本并将“pod 'Parse'”添加到我的 pod 文件并运行“pod install”后，此特定问题得到解决。

对于遇到相关问题的任何人，您应该尝试更新项目中剩余的旧依赖项，并查看哪个可以为您解决此问题。
