ios UIView常用动画效果

一

//调用

1 2 3 4 5 6

if(m_viewScenario.superview == nil)<br>{     m_viewScenario.alpha = 1.0;     m_viewScenario.transform = CGAffineTransformIdentity;     [self zoomIn:m_viewScenario andAnimationDuration:1.0 andWait:YES];     [self.view addSubview:m_viewScenario]; }

　　

//展示，由小变大

1 2 3 4 5 6 7 8 9 10 11 12 13

- (void)zoomIn: (UIView *)view andAnimationDuration: (float) duration andWait:(BOOL) wait {     __block BOOL done = wait;     view.transform = CGAffineTransformMakeScale(0, 0);     [UIView animateWithDuration:duration animations:^{         view.transform = CGAffineTransformIdentity;               } completion:^(BOOL finished) {         done = NO;     }];     while (done == YES)         [[NSRunLoop currentRunLoop] runUntilDate:[NSDate dateWithTimeIntervalSinceNow:0.01]]; }

//有大变小调用

1 2	[self zoomOut:m_viewScenario andAnimationDuration:1.0 andWait:NO]; [self removeScenarioView];

//大变小  函数

1 2 3 4 5 6 7 8 9 10 11

- (void)zoomOut: (UIView *)view andAnimationDuration: (float) duration andWait:(BOOL) wait{     __block BOOL done = wait;     view.transform = CGAffineTransformIdentity;     [UIView animateWithDuration:duration animations:^{         view.transform = CGAffineTransformMakeScale(0, 0);     } completion:^(BOOL finished) {         done = YES;     }];     while (done == NO)         [[NSRunLoop currentRunLoop] runUntilDate:[NSDate dateWithTimeIntervalSinceNow:0.01]]; }

　　

二，如果需要类似UIAlertView那种动画

显示调用

1 2 3 4 5 6 7 8

if(m_viewScenario.superview == nil) {     m_viewScenario.alpha = 1.0;     m_viewScenario.transform = CGAffineTransformIdentity;     [self.view addSubview:m_viewScenario];       [self zoomIn:m_viewScenario andAnimationDuration:1.0]; }

　　

小变大动画

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

- (void)zoomIn: (UIView *)view andAnimationDuration: (float) duration {     CAKeyframeAnimation * animation;     animation = [CAKeyframeAnimation animationWithKeyPath:@"transform"];     animation.duration = duration;     //animation.delegate = self;     animation.removedOnCompletion = NO;     animation.fillMode = kCAFillModeForwards;     NSMutableArray *values = [NSMutableArray array];     [values addObject:[NSValue valueWithCATransform3D:CATransform3DMakeScale(0.1, 0.1, 1.0)]];     [values addObject:[NSValue valueWithCATransform3D:CATransform3DMakeScale(1.2, 1.2, 1.0)]];     [values addObject:[NSValue valueWithCATransform3D:CATransform3DMakeScale(0.9, 0.9, 0.9)]];     [values addObject:[NSValue valueWithCATransform3D:CATransform3DMakeScale(1.0, 1.0, 1.0)]];     animation.values = values;     animation.timingFunction = [CAMediaTimingFunction functionWithName: @"easeInEaseOut"];     [view.layer addAnimation:animation forKey:nil]; }

　　

大变小，调用同上，函数稍有变化

1 2 3 4 5 6 7 8 9 10 11 12

- (void)zoomOut: (UIView *)view andAnimationDuration: (float) duration andWait:(BOOL) wait{     __block BOOL done = wait;     view.transform = CGAffineTransformIdentity;     [UIView animateWithDuration:duration animations:^{         view.transform = CGAffineTransformMakeScale(0, 0);         view.alpha = 0.0;     } completion:^(BOOL finished) {         done = YES;     }];     while (done == NO)         [[NSRunLoop currentRunLoop] runUntilDate:[NSDate dateWithTimeIntervalSinceNow:0.01]];
