在工程內(nèi)創(chuàng)建一個Foundation_log.m文件，將以下代碼復制進去即可
#import <Foundation/Foundation.h>
@implementation NSDictionary (Log)
- (NSString *)descriptionWithLocale:(id)locale
{
NSMutableString *string = [NSMutableString string];
// 開頭有個{
[string appendString:@"{\n"];
// 遍歷所有的鍵值對
[self enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {
[string appendFormat:@"\t%@", key];
[string appendString:@" : "];
[string appendFormat:@"%@,\n", obj];
}];
// 結(jié)尾有個}
[string appendString:@"}"];
// 查找最后一個逗號
NSRange range = [string rangeOfString:@"," options:NSBackwardsSearch];
if (range.location != NSNotFound)
[string deleteCharactersInRange:range];
return string;
}
@end
@implementation NSArray (Log)
- (NSString *)descriptionWithLocale:(id)locale
{
NSMutableString *string = [NSMutableString string];
// 開頭有個[
[string appendString:@"[\n"];
// 遍歷所有的元素
[self enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
[string appendFormat:@"\t%@,\n", obj];
}];
// 結(jié)尾有個]
[string appendString:@"]"];
// 查找最后一個逗號
NSRange range = [string rangeOfString:@"," options:NSBackwardsSearch];
if (range.location != NSNotFound)
[string deleteCharactersInRange:range];
return string;
}
@end
