- provite label property like textAliment,lineSpacing,font,color,layouttype
- support NSAttributedString dispaly
- customizable and detect animation by CAAnimateLabelDelegate
- customizable animate part of the label
1.Install the latest release of CocoaPods or update:
gem install cocoapods
2.Add to your Podfile:
pod 'CAAnimateLabel'
3.Install the pod or update:
pod install
pod update
1.Add to your Cartfile:
github "ChenAo0727/CAAnimateLabel"
2.run carthage to build the framework and drag the built CAAnimatedLabel.framework into your Xcode project.
carthage update --platform ios
3.On your application targets’ “Build Phases” settings tab, click the “+” icon and choose “New Run Script Phase”. Create a Run Script in which you specify your shell (ex: /bin/sh), add the following contents to the script area below the shell:
/usr/local/bin/carthage copy-frameworks
4.add the paths to the frameworks you want to use under “Input Files”, e.g.:
$(SRCROOT)/Carthage/Build/iOS/CAAnimatedLabel.framework
5.import
#import <CAAnimatedLabel/CAAnimatedLabel.h>
self.animateLabel = [CAAnimateLabel new];
self.animateLabel.frame = CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height);
[self.view insertSubview:self.animateLabel atIndex:0];
self.animateLabel.type = self.animateType;
self.animateLabel.layoutType = CATextLayoutSentenceType;
self.animateLabel.lineSpacing = 10;
self.animateLabel.textColor = [UIColor greenColor];
self.animateLabel.textAlignment = CATextAlignmentCenter;
self.animateLabel.font = [UIFont systemFontOfSize:18.0];
self.animateLabel.duration = 3.0;
self.animateLabel.delay = 0.5;
self.animateLabel.repeatCount = 2;
//animate part of label will be ignore if implement prepareTextAttributes
self.animateLabel.animateRange = NSMakeRange(10, 10);
self.animateLabel.text = @"青春，是人生中最美的风景。\n青春，是一场花开的遇见；\n青春，是一场痛并快乐着的旅行；\n青春，是一场轰轰烈烈的比赛；\n青春，是一场鲜衣奴马的争荣岁月；\n青春，是一场风花雪月的光阴。";
self.animateLabel.contentInsets = UIEdgeInsetsMake(100, 10, 10, 10);
if (self.animateType == CAAnimateLabelCustomType) {
self.animateLabel.layerAnimate = YES;
self.animateLabel.delegate = self;
self.animateLabel.restore = NO;
}
Conform to CAAnimateLabelDelegate.

}
- (void)prepareTextAttributes:(NSMutableArray<CATextAttribute *> *)textAttrs {
//custom animate part of label For example
for (CATextAttribute *attr in textAttrs) {
if (attr.lineIndex % 2 == 1) {
attr.animate = NO;
}
}
}
- (void)animationWillStartTextAttribute:(CATextAttribute *)textAttribute forIndex:(NSInteger)index {
//call animation start
}
- (void)animationDidEndTextAttribute:(CATextAttribute *)textAttribute forIndex:(NSInteger)index {
//call aniamtion end
}
- (void)prepareLayerByTextAttribute:(CATextAttribute *)textAttribute forIndex:(NSInteger)index {
//call when layerAnimate is YES prepare layer animation
}
- (CGRect)animationDrawRectForTextAttribute:(CATextAttribute *)textAttribute forIndex:(NSInteger)index {
// Reture draw animation rect
return textAttribute.rect;
}
- (void)animationAtRect:(CGRect)rect ForTextAttribute:(CATextAttribute *)textAttribute forIndex:(NSInteger)index {
//custom layer or draw aniamtion
