IOS應用/遊戲 項目封裝之:UILabel 應該如何拓展？

如果是在IOS的應用方面，很多時候，是不需要我們去做一些封裝的和添加一些比較好看，比較好看的UILabel顯示。

遊戲方面，就避免不了需要提高IOS完全沒有的顯示風格，這就需要提供炫的風格了。

但是，應用誰說的準就不用呢？

在發展到今天，開源的項目提供給我們很多的方便，在UILabel上面，就有開源的封裝類。

這個其實類似於上一節的，IOS 應用/遊戲項目應該如何靈活封裝 控件顯示樣式與項目顏色的公用    http://blog.csdn.net/zhbitxhd/article/details/24296067

實際上，這個開源的項目就是爲了完成同樣的事情。所以，我們不需要再造車輪

這裏提供鏈接以供使用，並且，我們的項目也在使用。

THLabel

文章中，有詳細的解釋如何使用。這裏我就不多說了。

Installation

Add CoreText.framework to your Link Binary with Libraries list.

And drag these files into your project:

• THLabel.h
• THLabel.m

You can create THLabels programmatically, or create them in Interface Builder by dragging an ordinary UILabel into your view and setting its Custom Class to THLabel.

Properties

    @property (nonatomic, assign) CGFloat shadowBlur;

Additionally to UILabel's shadowColor and shadowOffset, you can set a shadow blur to soften the shadow.

    @property (nonatomic, assign) CGFloat innerShadowBlur;
    @property (nonatomic, assign) CGSize innerShadowOffset;
    @property (nonatomic, strong) UIColor *innerShadowColor;

The inner shadow has similar properties as UILabel's shadow, once again additionally with a shadow blur. If an inner shadow and a stroke are overlapping, it will appear beneath the stroke.

    @property (nonatomic, assign) CGFloat strokeSize;
    @property (nonatomic, strong) UIColor *strokeColor;
    @property (nonatomic, assign) THLabelStrokePosition strokePosition;

You can set an outer, centered or inner stroke by setting the strokePosition property. Default value isTHLabelStrokePositionOutside. Other options are THLabelStrokePositionCenter andTHLabelStrokePositionInside.

    @property (nonatomic, strong) UIColor *gradientStartColor;
    @property (nonatomic, strong) UIColor *gradientEndColor;
    @property (nonatomic, copy) NSArray *gradientColors;

The gradient can consist of multiple colors, which have to be saved as UIColor objects in the gradientColorsarray. For more convenience, gradientStartColor and gradientEndColor will fill up the array accordingly.

    @property (nonatomic, assign) CGPoint gradientStartPoint;
    @property (nonatomic, assign) CGPoint gradientEndPoint;

The starting and ending points of the gradient are in the range 0 to 1, where (0, 0) is the top-left and (1, 1) the bottom-right of the text. The default value for gradientStartPoint is (0.5, 0.2) and for gradientEndPoint it is (0.5, 0.8).

    @property (nonatomic, assign) THLabelFadeTruncatingMode fadeTruncatingMode;

You can fade in/out your label by setting the fadeTruncatingMode property. Default value isTHLabelFadeTruncatingModeNone. The options are THLabelFadeTruncatingModeTail,THLabelFadeTruncatingModeHead and THLabelFadeTruncatingModeHeadAndTail.

    @property (nonatomic, assign) UIEdgeInsets textInsets;

Effects like stroke and shadow can't be drawn outside of the bounds of the label view. For labels that are not center-aligned, you may need to set text insets to move a bit away from the edge.
