NSArray+log.h
#import <Foundation/Foundation.h>@interface NSArray (log)@end
NSArray+log.m
#import "NSArray+log.h"@implementation NSArray (log)- (NSString *)descriptionWithLocale:(id)locale{ NSMutableString *string = [NSMutableString string]; // 开头有个[ [string appendString:@"[\n"]; // 遍历所有的元素 [self enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) { [string appendFormat:@"\t%@,\n", obj]; }]; // 结尾有个] [string appendString:@"]"]; // 查找最后一个逗号 NSRange range = [string rangeOfString:@"," options:NSBackwardsSearch]; if (range.location != NSNotFound) [string deleteCharactersInRange:range]; return string;}@end
重写NSDictionary的descriptionWithLocale方法:
NSDictionary.h
#import <Foundation/Foundation.h>@interface NSDictionary (log)@end
NSDictionary.m
#import "NSDictionary+log.h"@implementation NSDictionary (log)- (NSString *)descriptionWithLocale:(id)locale{ NSMutableString *string = [NSMutableString string]; // 开头有个{ [string appendString:@"{\n"]; // 遍历所有的键值对 [self enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) { [string appendFormat:@"\t%@", key]; [string appendString:@" : "]; [string appendFormat:@"%@,\n", obj]; }]; // 结尾有个} [string appendString:@"}"]; // 查找最后一个逗号 NSRange range = [string rangeOfString:@"," options:NSBackwardsSearch]; if (range.location != NSNotFound) [string deleteCharactersInRange:range]; return string;}@end
