AGSTextSymbol Class Reference
Description
Instances of this class represent text symbols. Symbols describe how graphics look on the map. Different symbols are used for graphics with different geometry types. Text symbols are used to display text for graphics. The graphics can be based on any type of geometry - point, multipoint, polyline, or polygon.

- 1.8
- (UIColor*) color [read, write, retain, inherited] |
Symbol color.
- Since:
- 1.0
- (AGSTextSymbolFontDecoration) fontDecoration [read, write, assign] |
The decoration on the font.
- Since:
- 1.8
- (NSString*) fontFamily [read, write, retain] |
The font family to use for the text.
- Since:
- 1.8
- (float) fontSize [read, write, assign] |
The size of the font.
- Since:

- (AGSTextSymbolFontWeight) fontWeight [read, write, assign] |
The weight of the font.
- Since:
- 1.8
- (AGSTextSymbolHAlignment) hAlignment [read, write, assign] |
The horizontal alignment of the text.
- Since:
- 1.8
- (BOOL) rotateAroundOffset [read, write, assign] |
Specifies whether the symbol should be rotated around its offset location or its center.

- (CGFloat) shadowBlur [read, write, assign] |
The amount of blur to apply to the shadow.
- Since:
- 1.8
- (UIColor*) shadowColor [read, write, retain] |
The color of the shadow.
- Since:
- 1.8
- (CGSize) shadowOffset [read, write, assign] |
The offset to apply to the shadow. This is in points.
- Since:

- (NSString*) textTemplate [read, write, retain] |
The text template to be applied when drawing a graphic. Tokens of the form ${...} in the textTemplate are replaced at runtime with corresponding values from the graphic's attributes. The final text is then displayed.
For example, consider a graphic which has an attribute STATE_NAME with the value California. For the symbol to draw the attribute's value, you need to set ${STATE_NAME} as the textTemplate. The token ${STATE_NAME} will then be automatically substituted with the value California when the symbol is drawn.
