Xcode NSLog打印中文

新建两个分类，一个NSArray分类、一个NSDictionary分类.在哪用就在那里import,或者加到.pch里面全局使用。

#import "NSArray+RMArray.h"
@implementation NSArray (RMArray)

- (NSString *)descriptionWithLocale:(id)locale{//打印中文
    NSMutableString *str = [NSMutableString stringWithFormat:@"%lu (\n", (unsigned long)self.count];
    
    for (id obj in self) {
        [str appendFormat:@"\t%@, \n", obj];
    }
    
    [str appendString:@")"];
    return str;
}
@end

#import "NSDictionary+RMDictionary.h"
@implementation NSDictionary (RMDictionary)

- (NSString *)descriptionWithLocale:(id)locale{//打印中文
    NSArray *allKeys = [self allKeys];
    NSMutableString *str = [[NSMutableString alloc] initWithFormat:@"{\t\n "];
    for (NSString *key in allKeys) {
        id value= self[key];
        [str appendFormat:@"\t \"%@\" = %@,\n",key, value];
    }
    [str appendString:@"}"];
    
    return str;
}
@end
