IOS 将打印字典和数组的内容由字符编码变为中文

#import <Foundation/Foundation.h>

@implementation NSDictionary (Log)
- (NSString *)descriptionWithLocale:(id)locale
{
NSMutableString *str = [NSMutableString string];

[str appendString:@"{\n"];

// 遍历字典的所有键值对
[self enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOLBOOL *stop) {
[str appendFormat:@"\t%@ = %@,\n", key, obj];
}];

[str appendString:@"}"];

// 查出最后一个,的范围
NSRange range = [str rangeOfString:@"," options:NSBackwardsSearch];
if (range.length != 0) {
// 删掉最后一个,
[str deleteCharactersInRange:range];
}

return str;
}
@end

@implementation NSArray (Log)
- (NSString *)descriptionWithLocale:(id)locale
{
NSMutableString *str = [NSMutableString string];

[str appendString:@"[\n"];

// 遍历数组的所有元素
[self enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOLBOOL *stop) {
[str appendFormat:@"%@,\n", obj];
}];

[str appendString:@"]"];

// 查出最后一个,的范围
NSRange range = [str rangeOfString:@"," options:NSBackwardsSearch];
if (range.length != 0) {
// 删掉最后一个,
[str deleteCharactersInRange:range];
}

return str;
}
@end
