我有一個iOS7應用程序,我試圖將CorePlot 1.4集成到(依賴項目安裝)中。CorePlot在iOS7應用程序中拋出異常app/Xcode5
@property (nonatomic) CPTGraphHostingView *hostingView;
和
_hostingView = [[CPTGraphHostingView alloc] initWithFrame:CGRectNull];
(_hostingView
受到自動佈局。)如果我再添加一個圖表:
CPTXYGraph *graph = [[CPTXYGraph alloc] initWithFrame:CGRectZero];
_hostingView.hostedGraph = graph;
我第一次得到這個異常:
-[CPTTextStyle attributes]: unrecognized selector sent to instance 0xa392900
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[CPTTextStyle attributes]: unrecognized selector sent to instance 0xa392900'
5 myapp 0x00074325 -[CPTAxis updateAxisLabelsAtLocations:inRange:useMajorAxisLabels:] + 1141
6 myapp 0x00075662 -[CPTAxis relabel] + 1202
絕望我hav Ë然後在updateAxisLabelsAtLocations:inRange:useMajorAxisLabels
固定的:
NSDictionary *textAttributes = nil;
BOOL hasAttributedFormatter = FALSE;
,然後得到一個異常:
-[__NSCFString sizeWithTextStyle:]: unrecognized selector sent to instance 0x9591e90
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFString sizeWithTextStyle:]: unrecognized selector sent to instance 0x9591e90'
5 myapp 0x00081520 -[CPTTextLayer sizeThatFits] + 320
6 myapp 0x0008163c -[CPTTextLayer sizeToFit] + 108
7 myapp 0x00080559 -[CPTTextLayer initWithText:style:] + 313
8 myapp 0x00074b87 -[CPTAxis updateAxisLabelsAtLocations:inRange:useMajorAxisLabels:] + 3159
9 myapp 0x00075672 -[CPTAxis relabel] + 1202
這在sizeThatFits
註釋掉這一行我已經然後 '固定':
else {
// textSize = [myText sizeWithTextStyle:self.textStyle];
}
接下來的例外是:
-[__NSCFString drawInRect:withTextStyle:inContext:]: unrecognized selector sent to instance 0xa162bd0
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFString drawInRect:withTextStyle:inContext:]: unrecognized selector sent to instance 0xa162bd0'
5 myapp 0x00081dc8 -[CPTTextLayer renderAsVectorInContext:] + 1144
6 myapp 0x00063f60 -[CPTLayer drawInContext:] + 112
其通過renderAsVectorInContext
註釋如下代碼的固定:
else {
// [myText drawInRect:newBounds
// withTextStyle:self.textStyle
// inContext:context];
}
現在最後沒有引發異常和圖形邊界被示出。但是,如果我然後開始添加數據/圖例等新的異常拋出:(
沒有文字顯示在軸等。當然,這是因爲我已經註釋掉了代碼。但任何線索爲什麼這些例外?都扔我絕望; S
好像我已經錯過了在積分一些基本的東西,但我的集成(CorePlot 1.3雖然)在iOS6的應用程序,前一段時間的工作罰款Xcode4
謝謝埃裏克 - 很好的解脫!現在感到愚蠢:)任何計劃重構CorePlot使用ARC? –
2.0版本(已經在分支機構中)將放棄GC支持並使用ARC。目前還沒有發佈時間表。 –
