創建高分列表

-1

我正在製作一款遊戲應用程序，嘗試儘可能多地得分，並且我一直試圖創建一個高分榜。我是這樣做的，通過測量得分是否高於先前的第一，如果它然後把第一作爲2，2作爲3，3作爲4等等，等等，輕輕推動一切步驟，你知道。但我使用不工作的方法;（創建高分列表

顯示分數代碼：代碼：

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentPath = [paths objectAtIndex:0]; 
NSString *path = [documentPath stringByAppendingPathComponent:@"highscore.save"]; 

NSMutableDictionary* myDict = [[NSMutableDictionary alloc] init]; 

myDict = [NSKeyedUnarchiver unarchiveObjectWithFile:path]; 
NSString *nssScore1 = [myDict objectForKey:@"Score1"]; 
NSString *nssName1 = [myDict objectForKey:@"Name1"]; 
NSString *nssScore2 = [myDict objectForKey:@"Score2"]; 
NSString *nssName2 = [myDict objectForKey:@"Name2"]; 
NSString *nssScore3 = [myDict objectForKey:@"Score3"]; 
NSString *nssName3 = [myDict objectForKey:@"Name3"]; 
NSString *nssScore4 = [myDict objectForKey:@"Score4"]; 
NSString *nssName4 = [myDict objectForKey:@"Name4"]; 
NSString *nssScore5 = [myDict objectForKey:@"Score5"]; 
NSString *nssName5 = [myDict objectForKey:@"Name5"]; 
NSString *nssScore6 = [myDict objectForKey:@"Score6"]; 
NSString *nssName6 = [myDict objectForKey:@"Name6"]; 
NSString *nssScore7 = [myDict objectForKey:@"Score7"]; 
NSString *nssName7 = [myDict objectForKey:@"Name7"]; 
NSString *nssScore8 = [myDict objectForKey:@"Score8"]; 
NSString *nssName8 = [myDict objectForKey:@"Name8"]; 
NSString *nssScore9 = [myDict objectForKey:@"Score9"]; 
NSString *nssName9 = [myDict objectForKey:@"Name9"]; 
NSString *nssScore10 = [myDict objectForKey:@"Score10"]; 
NSString *nssName10 = [myDict objectForKey:@"Name10"]; 
highestscore = [nssScore1 intValue]; 
score1i = [nssScore1 intValue]; 
score2i = [nssScore2 intValue]; 
score3i = [nssScore3 intValue]; 
score4i = [nssScore4 intValue]; 
score5i = [nssScore5 intValue]; 
score6i = [nssScore6 intValue]; 
score7i = [nssScore7 intValue]; 
score8i = [nssScore8 intValue]; 
score9i = [nssScore9 intValue]; 
score10i = [nssScore10 intValue]; 

if(score1i > 0){ 
    NSString *str1 = [NSString stringWithFormat:@"1. %@ | %i points", nssName1, score1i]; 
    score1.text = str1; 
} else { 
    score1.text = @"No Scores available yet"; 
} 
if(score2i > 0){ 
    NSString *str2 = [NSString stringWithFormat:@"2. %@ | %i points", nssName2, score2i]; 
    score2.text = str2; 
} else { 
    [score2 setHidden:1]; 
} 
if(score3i > 0){ 
    NSString *str3 = [NSString stringWithFormat:@"3. %@ | %i points", nssName3, score3i]; 
    score3.text = str3; 
} else { 
    [score3 setHidden:1]; 
} 
if(score4i > 0){ 
    NSString *str4 = [NSString stringWithFormat:@"4. %@ | %i points", nssName4, score4i]; 
    score4.text = str4; 
} else { 
    [score4 setHidden:1]; 
} 
if(score5i > 0){ 
    NSString *str5 = [NSString stringWithFormat:@"5. %@ | %i points", nssName5, score5i]; 
    score5.text = str5; 
} else { 
    [score5 setHidden:1]; 
} 
if(score6i > 0){ 
    NSString *str6 = [NSString stringWithFormat:@"6. %@ | %i points", nssName6, score6i]; 
    score6.text = str6; 
} else { 
    [score6 setHidden:1]; 
} 
if(score7i > 0){ 
    NSString *str7 = [NSString stringWithFormat:@"7. %@ | %i points", nssName7, score7i]; 
    score7.text = str7; 
} else { 
    [score7 setHidden:1]; 
} 
if(score8i > 0){ 
    NSString *str8 = [NSString stringWithFormat:@"8. %@ | %i points", nssName8, score8i]; 
    score8.text = str8; 
} else { 
    [score8 setHidden:1]; 
} 
if(score9i > 0){ 
    NSString *str9 = [NSString stringWithFormat:@"9. %@ | %i points", nssName9, score9i]; 
    score9.text = str9; 
} else { 
    [score9 setHidden:1]; 
} 
if(score10i > 0){ 
    NSString *str10 = [NSString stringWithFormat:@"10. %@ | %i points", nssName10, score10i]; 
    score10.text = str10; 
} else { 
    [score10 setHidden:1]; 
}

並保存比分代碼：

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentPath = [paths objectAtIndex:0]; 
NSString *path = [documentPath stringByAppendingPathComponent:@"highscore.save"]; 

NSMutableDictionary* myDict1 = [[NSMutableDictionary alloc] init]; 

myDict1 = [NSKeyedUnarchiver unarchiveObjectWithFile:path]; 
NSString *nssScore1 = [myDict1 objectForKey:@"Score1"]; 
NSString *nssName1 = [myDict1 objectForKey:@"Name1"]; 
NSString *nssScore2 = [myDict1 objectForKey:@"Score2"]; 
NSString *nssName2 = [myDict1 objectForKey:@"Name2"]; 
NSString *nssScore3 = [myDict1 objectForKey:@"Score3"]; 
NSString *nssName3 = [myDict1 objectForKey:@"Name3"]; 
NSString *nssScore4 = [myDict1 objectForKey:@"Score4"]; 
NSString *nssName4 = [myDict1 objectForKey:@"Name4"]; 
NSString *nssScore5 = [myDict1 objectForKey:@"Score5"]; 
NSString *nssName5 = [myDict1 objectForKey:@"Name5"]; 
NSString *nssScore6 = [myDict1 objectForKey:@"Score6"]; 
NSString *nssName6 = [myDict1 objectForKey:@"Name6"]; 
NSString *nssScore7 = [myDict1 objectForKey:@"Score7"]; 
NSString *nssName7 = [myDict1 objectForKey:@"Name7"]; 
NSString *nssScore8 = [myDict1 objectForKey:@"Score8"]; 
NSString *nssName8 = [myDict1 objectForKey:@"Name8"]; 
NSString *nssScore9 = [myDict1 objectForKey:@"Score9"]; 
NSString *nssName9 = [myDict1 objectForKey:@"Name9"]; 

self.String = textname.text; 
NSString *nameString = String; 
NSString *nssHighScore = [NSString stringWithFormat:@"%i", highestscore]; 
NSString *nssIdentifier = [NSString stringWithFormat:@"%@", nameString]; 

NSMutableDictionary* myDict = [[NSMutableDictionary alloc] init]; 

[myDict setObject:nssIdentifier forKey:@"Name1"]; 
[myDict setObject:nssHighScore forKey:@"Score1"]; 
[myDict setObject:nssName1 forKey:@"Name2"]; 
[myDict setObject:nssScore1 forKey:@"Score2"]; 
if(nssScore2 > 0){ 
[myDict setObject:nssName2 forKey:@"Name3"]; 
[myDict setObject:nssScore2 forKey:@"Score3"]; 
} 
if(nssScore3 > 0){ 
[myDict setObject:nssName3 forKey:@"Name4"]; 
[myDict setObject:nssScore3 forKey:@"Score4"]; 
} 
if(nssScore4 > 0){ 
[myDict setObject:nssName4 forKey:@"Name5"]; 
[myDict setObject:nssScore4 forKey:@"Score5"]; 
} 
if(nssScore5 > 0){ 
[myDict setObject:nssName5 forKey:@"Name6"]; 
[myDict setObject:nssScore5 forKey:@"Score6"]; 
} 
if(nssScore6 > 0){ 
[myDict setObject:nssName6 forKey:@"Name7"]; 
[myDict setObject:nssScore6 forKey:@"Score7"]; 
} 
if(nssScore7 > 0){ 
[myDict setObject:nssName7 forKey:@"Name8"]; 
[myDict setObject:nssScore7 forKey:@"Score8"]; 
} 
if(nssScore8 > 0){ 
[myDict setObject:nssName8 forKey:@"Name9"]; 
[myDict setObject:nssScore8 forKey:@"Score9"]; 
} 
if(nssScore9 > 0){ 
[myDict setObject:nssName9 forKey:@"Name10"]; 
[myDict setObject:nssScore9 forKey:@"Score10"]; 
} 

NSArray *paths1 = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentPath1 = [paths1 objectAtIndex:0]; 
NSString *path1 = [documentPath1 stringByAppendingPathComponent:@"highscore.save"]; 

[NSKeyedArchiver archiveRootObject:myDict toFile:path1];

現在這樣做，排行榜＃1已被保存並取代舊的，但前一個號碼只是消失，沒有其他的（3,4,5等）顯示。你能找到一個錯誤或我錯過了什麼嗎？謝謝！

第一件事的第一件事。你這樣做是錯誤的！

只需使用數組創建一個高分管理器類！下面是一個例子：

HighScore.h

@interface HighScore : NSObject<NSCoding> 

+(id) highScoreWithName:(NSString *) name score:(int) score; 

-(id) initWithName:(NSString *) name score:(int) score; 

@property (assign) int score; 
@property (copy) NSString *name; 

@end

HighScore.m

@implementation HighScore 

@synthesize score = _score, name = _name; 

+(id) highScoreWithName:(NSString *)name score:(int)score 
{ 
    return [[self alloc] initWithName:name score:score]; 
} 

-(id) initWithName:(NSString *)name score:(int)score 
{ 
    if ((self = [super init])) 
    { 
     self.name = name; 
     self.score = score; 
    } 

    return self; 
} 

-(id) initWithCoder:(NSCoder *)aDecoder 
{ 
    if ((self = [super init])) 
    { 
     self.name = [aDecoder decodeObjectForKey:@"name"]; 
     self.score = [aDecoder decodeIntForKey:@"score"]; 
    } 

    return self; 
} 

-(void) encodeWithCoder:(NSCoder *)aCoder 
{ 
    [aCoder encodeObject:self.name forKey:@"name"]; 
    [aCoder encodeInt:self.score forKey:@"score"]; 
} 

-(NSString *) description 
{ 
    return [NSString stringWithFormat:@"%@ - %@: %i", [super description], self.name, self.score]; 
} 

@end

HighScoreManager.h

@interface HighScoreManager : NSObject { 
    NSMutableArray *_scores; 
} 

+(HighScoreManager *) instance; 

-(void) addHighScore:(HighScore *) score; 
-(void) clearHighScores; 

-(HighScore *) bestScore; 
-(NSArray *) sortedScores; 

@end

HighScoreManager.m

@implementation HighScoreManager 

+(HighScoreManager *) instance 
{ 
    static HighScoreManager *manager; 
    static dispatch_once_t onceToken; 
    dispatch_once(&onceToken, ^{ 
     manager = [[HighScoreManager alloc] init]; 
    }); 

    return manager; 
} 

-(id) init 
{ 
    if ((self = [super init])) 
    { 
     // create from the file 
     _scores = [NSKeyedUnarchiver unarchiveObjectWithFile:@"highscore.sav"]; 

     if (_scores == nil) 
      _scores = [NSMutableArray new]; 
    } 

    return self; 
} 

-(void) _synchronize 
{ 
    // write to the file 
    [NSKeyedArchiver archiveRootObject:_scores toFile:@"highscore.sav"]; 
} 

-(void) addHighScore:(HighScore *)score 
{  
    // add the score to the end of the array 
    [_scores addObject:score]; 

    // sort on insert 
    [_scores sortUsingComparator:^NSComparisonResult(id obj1, id obj2) { 
     HighScore *hs1 = obj1; 
     HighScore *hs2 = obj2; 

     return hs1.score - hs2.score; 
    }]; 

    // then synchronize 
    [self _synchronize]; 
} 

-(void) clearHighScores 
{ 
    // remove all of the objects 
    [_scores removeAllObjects]; 

    // then synchronize 
    [self _synchronize]; 
} 

-(HighScore *) bestScore 
{ 
    // simply return the last object in the array 
    return [_scores lastObject]; 
} 

-(NSArray *) sortedScores 
{ 
    // note this returns them from lowest to highest scores. 
    // also notice we make a copy of the array. This way we 
    // can still add scores without compromising the reciever 
    // of this function. 
    return [NSArray arrayWithArray:_scores]; 
} 

@end

然後你只需簡單地添加到高分列表，你走，並負責所有的內部的東西給你。

我將如何實現這一點？我真的不明白，顯然我是一個新手編碼器; /如果我修復了當前的代碼，我的意思是它應該能夠正常工作，如果我正確地做對了嗎？ –

你只需用高分列表中的數組創建一個UITableView，並顯示它。 –
