我在一個簡單的欄中顯示了一些數據,這些數據顯示了一些數值,所有工作都正常,但是現在要爲我的Y軸構建比例,我有一些基本的東西存在一些問題,obj c「for loop」路障
I = 900
然後根據一些簡單的測試在這種情況下測試得到我的圖表與scaleMaxInt
天花板值,我得到例如9個師[加零] ...
這樣做事情工作,我創建了int pp = 100
- (void) drawScaleLabels:(int)scaleMaxInt
{
//temp division for scale, NOTE WHERE TO USE 9 DIVISIONS!!
int scaleStep = scaleMaxInt/9;
NSLog(@"va ::%d", scaleStep);
// case scaleMax : 0 < scaleMax < 1000
float scaleDiv = 31.5;
for (int i = 0; i<9; i++)
{ // is 8, to 9 only for testing!!
int pp = 100;
self.divScaleLabel = [[[UILabel alloc] initWithFrame:CGRectMake(469, scaleDiv+286, 60, 14)]autorelease];
self.divScaleLabel.font = [UIFont fontWithName:@"FS Albert" size:14];
self.divScaleLabel.textColor = [UIColor whiteColor];
self.divScaleLabel.textAlignment = UITextAlignmentRight;
self.divScaleLabel.text =[NSString stringWithFormat:@"$%d",scaleMaxInt-scaleStep];
self.divScaleLabel.backgroundColor =[UIColor clearColor];
[self.view addSubview:self.divScaleLabel];
scaleDiv = scaleDiv + 31.5;
scaleStep = scaleStep+pp;
}
}
至極顯示值列表在我的Y軸:900,800,700,600 ... 0
,但如果我使用的int scaleStep = scaleMaxInt/9
結果它給我的名單,但與的值* 2
- (void) drawScaleLabels:(int)scaleMaxInt
{
//temp division for scale, NOTE WHERE TO USE 9 DIVISIONS!!
int scaleStep = scaleMaxInt/9;
NSLog(@"va ::%d", scaleStep);
// case scaleMax : 0 < scaleMax < 1000
float scaleDiv = 31.5;
for (int i = 0; i<9; i++)
{ // is 8, to 9 only for testing!!
//int pp = 100;
self.divScaleLabel = [[[UILabel alloc] initWithFrame:CGRectMake(469, scaleDiv+286, 60, 14)]autorelease];
self.divScaleLabel.font = [UIFont fontWithName:@"FS Albert" size:14];
self.divScaleLabel.textColor = [UIColor whiteColor];
self.divScaleLabel.textAlignment = UITextAlignmentRight;
self.divScaleLabel.text =[NSString stringWithFormat:@"$%d",scaleMaxInt-scaleStep];
self.divScaleLabel.backgroundColor =[UIColor clearColor];
[self.view addSubview:self.divScaleLabel];
scaleDiv = scaleDiv + 31.5;
NSLog(@"va ::%d", scaleStep);
scaleStep = scaleStep+scaleStep;
}
}
所以Y軸爲,900,800,700,500,100,-700 ...- 24700
林愚蠢卡住此!
我怎樣才能生成Y軸的列表?,動態值,依賴於scaleMaxInt
,不會混淆?
非常感謝!
多數民衆贊成它!,謝謝,經過9個小時的編碼,我有點閉合! – MaKo 2012-01-30 06:09:41
