显示NSDictionary中的每个项目

Question

我正在尝试在NSDictionary中显示每个项目。我尝试过使用for循环但是没有用。

Answer 1

试试此代码

for(NSString *key in [dict allKeys]) {
  NSLog(@"%@",[dict objectForKey:key]);
}

Answer 2

怎么样？

NSLog(@"Dictionary: %@", [myDictionary description]);

似乎为我工作......

Answer 3

如果你想将它保存在NSString上，你可以使用

NSMutableString *stringUserInfo = [[NSMutableString alloc] init];
for (NSString *aKey in dictionary.allKeys)
    [stringUserInfo appendFormat:@"%@ : %@\n",aKey,[dictionary valueForKey:aKey]];

Answer 4

*Try this simple example:

//.h file

@interface DictionaryClass : NSObject
{
    NSDictionary *dict;
}

-(void) intialiseDictionary;

-(void) displayDictonary;

-------------------------------------------------------
//.m file
#import "DictionaryClass.h"

@implementation DictionaryClass

-(void) intialiseDictionary

{

    dict = @{@"key1":@"object1",@"key2":@"object2",@"key3":@"object3",@"key4":@"object4"};

}

-(void) displayDictonary

{
    for(NSString *keys in dict)
    {
        NSLog(@"\n Dictionary object = %@",[dict objectForKey:keys]);

    }

}

@end
-------------------------------------------------------

//main function

#import <Foundation/Foundation.h>
#import "DictionaryClass.h"

int main(int argc, const char * argv[])

{
    @autoreleasepool

    {
        DictionaryClass *obj = [[DictionaryClass alloc]init];

        [obj intialiseDictionary];
        [obj displayDictonary];
    }
    return 0;
}*

Answer 5

这对我有用，对调试非常有用。

NSDictionary * jsonDictionary = [theJSON JSONValue];

NSLog(@"dictionary data %@",jsonDictionary);

Answer 6

我认为您可以使用

打印NSDictionary

NSDictionary * dic;

NSLog（@“nsdic =％@”，dic）;

希望得到它的帮助。
