OC solve the garbage problem NSArray, NSDictionary appear directly print Chinese

In iOS development, which often need to see if the array elements have to be what you want, but Apple did not make a direct deal with the array have Chinese printing, direct printing will be a bunch of very nasty things, to solve it is actually very simple, is the need to add a category for NSArray, rewrite - (NSString *) descriptionWithLocale: (id) locale method to

code show as below:

#import "NSArray+Log.h"

@implementation NSArray (Log)


- (NSString *)descriptionWithLocale:(id)locale
{
    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

Similarly NSDictionary to solve the garbage problem, also you need to add a NSDictionary class classification, rewrite - (NSString *) descriptionWithLocale: (id) locale method

code show as below:

 1 #import "NSDictionary+MyLog.h"
 2 
 3 @implementation NSDictionary (MyLog)
 4 
 5 
 6 - (NSString *)descriptionWithLocale:(id)locale
 7 {
 8     NSArray *allKeys = [self allKeys];
 9     NSMutableString *str = [[NSMutableString alloc] initWithFormat:@"{\t\n "];
10     for (NSString *key in allKeys) {
11         id value= self[key];
12         [str appendFormat:@"\t \"%@\" = %@,\n",key, value];
13     }
14     [str appendString:@"}"];
15     
16     return str;
17 }
18 @end
