時常用Xcode除錯的工程師都知道，Xcode對中文字還不是很友善，因為除錯時印出的內容，中文字都會變成以\U為開頭的編碼，如：

\U900d\U9059\U6587\U5de5\U4f5c\U5ba4

儘管知道這是中文字，但實在很難確認這行代表什麼字啊⋯⋯

好在總是有解決方案，我強者同事阿宅，找到解法更發揚光大，讓任何人只要引用自訂Category，之後在Xcode除錯平台上必能如實顯示中文字！

一般而言我們常用容器Array與Dictionary，所以自訂這兩個Category匯入專案中，也不用import即能作用於所有專案中任何地方，實在太方便啦！

現在我就來分享這兩個Category（四個檔案），希望對所有以Xcode來寫程式的人都有注意，所謂「工欲善其事，必先利其器」，以增進我們工作效率與產能！

• 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 *str = [NSMutableString stringWithFormat:@"%@ count:%lu \n[\n", [[self class] description], (unsigned long)self.count];
    
    for (NSInteger k = 0; k < self.count; k++) {
        
        if (k != 0) {
            [str appendString:@",\n"];
        }
        
        {
            id obj = self[k];
            NSString *willAdd = [NSString stringWithFormat:@"%@", obj];
            
            willAdd = [willAdd stringByReplacingOccurrencesOfString:@"\n" withString:@"\n\t"];
            willAdd = [@"\t" stringByAppendingString:willAdd];
            
            [str appendString:willAdd];
        }
    }
    
    [str appendString:@"\n]"];
    
    return str;
}

• NSDictionary+Log.h

#import <Foundation/Foundation.h>

@interface NSDictionary (Log)

@end

• NSDictionary+Log.m

#import "NSDictionary+Log.h"

@implementation NSDictionary (Log)

- (NSString *)descriptionWithLocale:(id)locale
{
    NSArray *allKeys = [self allKeys];
    
    NSMutableString *str = [NSMutableString stringWithFormat:@"%@ count:%lu \n{\n", [[self class] description], (unsigned long)self.count];
    
    for (NSInteger k = 0; k < self.count; k++) {
        
        if (k != 0) {
            [str appendString:@",\n"];
        }
        {
            id obj = allKeys[k];
            NSString *willAdd = [NSString stringWithFormat:@"\"%@\" = ", obj];
            willAdd = [@"\t" stringByAppendingString:willAdd];

            [str appendString:willAdd];
        }

現在我們就來測試套用前與套用後的效果，以下列程式碼為例：

    NSDictionary *happyDict = @{@"Name" : @"黑皮棉", @"Company" : @"逍遙文工作室"};
    NSLog(@"happyDict: %@", happyDict);
    
    NSArray *happyArr = @[@"黑皮棉", @"逍遙文工作室"];
    NSLog(@"happyArr: %@", happyArr);

套用前：

happyDict: {
Company = “\U900d\U9059\U6587\U5de5\U4f5c\U5ba4″;
Name = “\U9ed1\U76ae\U68c9″;
}
happyArr: (
“\U9ed1\U76ae\U68c9″,
“\U900d\U9059\U6587\U5de5\U4f5c\U5ba4″
)

套用後：

happyDict: __NSDictionaryI count:2
{
“Company" = 逍遙文工作室,
“Name" = 黑皮棉
}
happyArr: __NSArrayI count:2
[
黑皮棉,
逍遙文工作室
]

是不是很讓人著迷呀！
