iOS中给自定义tabBar的按钮添加点击放大缩小的动画效果

之前想过一些通过第三方的方式实现动画，感觉有点麻烦，就自己写了一个

不足之处还望大家多多指出

// 一句话,写在uitabbarcontroller.m脚本中,tabbar是自动执行的方法 
// 点击tabbaritem自动调用 
-(void)tabbar:(uitabbar *)tabbar didselectitem:(uitabbaritem *)item 
{ 
nsinteger index = [self.tabbar.items indexofobject:item]; 
[self animationwithindex:index]; 
if([item.title isequaltostring:@"发现"]) 
{ 
// 也可以判断标题,然后做自己想做的事<img alt="得意" src="http://static.blog.csdn.net/xheditor/xheditor_emot/default/proud.gif" /> 
} 
} 
- (void)animationwithindex:(nsinteger) index { 
nsmutablearray * tabbarbuttonarray = [nsmutablearray array]; 
for (uiview *tabbarbutton in self.tabbar.subviews) { 
if ([tabbarbutton iskindofclass:nsclassfromstring(@"uitabbarbutton")]) { 
[tabbarbuttonarray addobject:tabbarbutton]; 
} 
} 
cabasicanimation*pulse = [cabasicanimation animationwithkeypath:@"transform.scale"]; 
pulse.timingfunction= [camediatimingfunction functionwithname:kcamediatimingfunctioneaseineaseout]; 
pulse.duration = 0.08; 
pulse.repeatcount= 1; 
pulse.autoreverses= yes; 
pulse.fromvalue= [nsnumber numberwithfloat:0.7]; 
pulse.tovalue= [nsnumber numberwithfloat:1.3]; 
[[tabbarbuttonarray[index] layer] 
addanimation:pulse forkey:nil]; 
}

以上所述是小编给大家介绍的ios中给自定义tabbar的按钮添加点击放大缩小的动画效果，希望对大家有所帮助
