AGSSimpleFillSymbol Class Reference
Description
Instances of this class represent simple fill symbols. Symbols describe how graphics look on the map. Different symbols are used for graphics with different geometry types. Fill symbols are used with graphics which are based on a polygon geometry. The symbol can fill the interior of a polygon graphic with a solid color. In addition, the symbol can have an optional outline which is defined by a line symbol.

Property Documentation
- (UIColor*) color [read, write, retain, inherited] |
This outline of the symbol.
- Since:
- 2.2
- (BOOL) readyToDraw [read, write, assign, inherited] |
Property called by the framework. Most symbols should have this set to YES as soon as the symbol is init'ed. If a symbol needs to access a resource asynchronously before it's ready to draw then it should be set to NO initially then YES once it is ready. This is not as efficient as if a symbol is readyToDraw to begin with, however, so custom symbols should only set this to NO initially if absolutely necessary.
