在iOS中打印字典或者数组对象，系统会默认调用字典对象和数组对象的descriptionWithLocale:方法。所以解决方案就是增加在.m文件中重写了两个descriptionWithLocale:方法

字典
#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
数组
#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
