出现这种情况,主要是属性名中包含 关键字.
You can solve this by:
- Renaming that property:
@property (strong, nonatomic) NSString *theNewTitle;
- Keeping the property name and specifying a getter name that doesn’t begin with one of the special method name prefixes:
@property (strong, nonatomic, getter=theNewTitle) NSString *newTitle;
- Keeping both the property name and the getter name, and telling the compiler that, even though the getter name starts with
new
,
it belongs to thenone
method
family as opposed to thenew
method
family:#ifndef __has_attribute #define __has_attribute(x) 0 // Compatibility with non-clang compilers #endif #if __has_attribute(objc_method_family) #define BV_OBJC_METHOD_FAMILY_NONE __attribute__((objc_method_family(none))) #else #define BV_OBJC_METHOD_FAMILY_NONE #endif @interface ViewController : UIViewController @property (strong, nonatomic) NSString *newTitle; - (NSString *)newTitle BV_OBJC_METHOD_FAMILY_NONE; @end
Note that even though this solution allows you to keep
newTitle
as
both the property name and the getter name, having a method called-newTitle
that
doesn’t return an object owned by the caller can be confusing for other people reading your code.
error: property's synthesized getter follows Cocoa naming convention for returning 'owned' objects
