在我的HighscoreVC i顯示索引，名稱和分數。我有一個重置按鈕。當我按下按鈕時，名稱和分數等所有條目都必須默認。用名稱和分數重新加載高分
所以這裏是我的繪製代碼高分：右
-(void) viewDidLoad {
[super viewDidLoad];
NSArray *highscore = [[[HighscoreModel alloc] init] getHighscore];
NSInteger i = 0;
for (NSDictionary *scoreDict in highscore) {
if (i<=4) {
[self addScoreRowViewWithIndexLeft:(++i) andName:[scoreDict objectForKey:@"name"] andScore:[[scoreDict objectForKey:@"points"] integerValue]];
}
else if (i>=5) {
[self addScoreRowViewWithIndexRight:(++i) andName:[scoreDict objectForKey:@"name"] andScore:[[scoreDict objectForKey:@"points"] integerValue]];
}
}
}
-(void) addScoreRowViewWithIndexLeft:(NSInteger)index andName: (NSString *)name andScore: (NSInteger)score {
UIView *scoreRowView = [[UIView alloc] initWithFrame:CGRectMake(122, 113 + index * 80, 280, 20)];
UILabel *nameLabel = [[UILabel alloc] initWithFrame:CGRectMake(100, 20, 180, 20)];
UILabel *scoreLabel = [[UILabel alloc] initWithFrame:CGRectMake(325, 20, 50, 20)];
UIColor *color = [UIColor colorWithRed:96.0f/255.0f green:96.0f/255.0f blue:96.0f/255.0f alpha:1.0];
[nameLabel setText:name];
[nameLabel setTextAlignment:NSTextAlignmentCenter];
[nameLabel setFont:[UIFont fontWithName:@"DINAlternate-Bold" size:18]];
[nameLabel setTextColor:color];
if (![name isEqual: @"DEFAULT"]) {
_resetButton.hidden = NO;
}
[scoreLabel setText:[@((int)score) stringValue]];
[scoreLabel setTextAlignment:NSTextAlignmentCenter];
[scoreLabel setFont:[UIFont fontWithName:@"DINAlternate-Bold" size:18]];
[scoreLabel setTextColor:color];
[scoreRowView addSubview:nameLabel];
[scoreRowView addSubview:scoreLabel];
[self.backgroundView addSubview:scoreRowView];
}
相同的代碼。
，這是我的復位按鈕：
- (IBAction)yesButton:(id)sender {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults removeObjectForKey: @"highscore"];
NSArray *highscore = [[[HighscoreModel alloc] init] getHighscore];
NSInteger i = 0;
for (NSDictionary *scoreDict in highscore) {
if (i<=4) {
[self addScoreRowViewWithIndexLeft:(++i) andName:[scoreDict objectForKey:@"name"] andScore:[[scoreDict objectForKey:@"points"] integerValue]];
}
else if (i>=5) {
[self addScoreRowViewWithIndexRight:(++i) andName:[scoreDict objectForKey:@"name"] andScore:[[scoreDict objectForKey:@"points"] integerValue]];
}
}
[self.backgroundView setNeedsDisplay];
}
，但它不能正常工作。它將默認的高分放在舊的高分上。沒有刪除舊文本。如果我更改爲其他VC，回到我的高分，這是正確顯示......
