有没有办法记录 Objective-C 实例的所有属性值

我只是想知道是否有一种快速简便的方法可以将我的类的属性的所有各种值打印到日志中以进行调试。就像我想知道所有 BOOL、浮点数等的值是什么。

这个问题 https://stackoverflow.com/questions/9269372/loop-through-all-object-properties-at-runtime看来他们已经找到了你问题的答案。

Update:

我很好奇，做了一个类别：

//Using Xcode 4.5.2 - iOS 6 - LLDB - Automatic Reference Counting

//NSObject+logProperties.h    
@interface NSObject (logProperties)
- (void) logProperties;
@end

//NSObject+logProperties.m
#import "NSObject+logProperties.h"
#import <objc/runtime.h>

@implementation NSObject (logProperties)

- (void) logProperties {

    NSLog(@"----------------------------------------------- Properties for object %@", self);

    @autoreleasepool {
        unsigned int numberOfProperties = 0;
        objc_property_t *propertyArray = class_copyPropertyList([self class], &numberOfProperties);
        for (NSUInteger i = 0; i < numberOfProperties; i++) {
            objc_property_t property = propertyArray[i];
            NSString *name = [[NSString alloc] initWithUTF8String:property_getName(property)];
            NSLog(@"Property %@ Value: %@", name, [self valueForKey:name]);
        }
        free(propertyArray);
    }    
    NSLog(@"-----------------------------------------------");
}

@end

将其包含在您的班级中：#import "NSObject+logProperties.h"

并打电话[self logProperties];到那些属性！
