解决Xcode8控制台无法输出中文

由于XCode8更新后，第三方插件基本上不能使用。

控制台输出的数据是Unicode格式，为了方便使用，只需要在项目中新建一个.m文件Foundation+NSLog.m。注:（不需要创建.h文件）

#import <Foundation/Foundation.h>

@implementation NSDictionary (NSLog)
- (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

@implementation NSArray (NSLog)

- (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

将这段代码放入Foundation+NSLog中即可。
