利用分类解决字典、数组打印问题

新建一个NSArray的分类

.h文件

#import

@interface NSArray (Log)

@end

@interface NSDictionary (Log)

@end


.m文件

#import "NSArray+Log.h"

@implementation NSArray (Log)

- (NSString *)descriptionWithLocale:(id)locale

{

NSMutableString *strM = [NSMutableString stringWithString:@"(\n"];

[self enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {

[strM appendFormat:@"\t%@,\n", obj];

}];

[strM appendString:@")"];

return strM;

}

@end

@implementation NSDictionary (Log)

- (NSString *)descriptionWithLocale:(id)locale

{

NSMutableString *strM = [NSMutableString stringWithString:@"{\n"];

[self enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {

[strM appendFormat:@"\t%@ = %@;\n", key, obj];

}];

[strM appendString:@"}\n"];

return strM;

}

@end
