Iphone Android Windows Phone 其他技术

防止屏幕暗掉锁屏

[[UIApplication sharedApplication] setIdleTimerDisabled:YES];

将图片从左到右翻页效果显示

UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 0, 470)];

[imageView setImage:[UIImage imageNamed:@"Bg.jpg"]];

self.myImageView =imageView;

[self.view addSubview:imageView];

[imageView release];

CGContextRef context = UIGraphicsGetCurrentContext();

[UIView beginAnimations:nil context:context];

[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];

[UIView setAnimationDuration:0.5];

[myImageView setFrame:CGRectMake(0, 0, 310, 470)];

[UIView commitAnimations];

让覆盖在下面层的视图接受触摸事件

searchImage.exclusiveTouch = YES;//第一层

searchImage.userInteractionEnabled = NO;

myMapView.exclusiveTouch = NO;//第二层

myMapView.userInteractionEnabled = YES;

View的缩放

NSValue *touchPointValue = [[NSValue valueWithCGPoint:CGPointMake(100,100)] retain];

[UIView beginAnimations:nil context:touchPointValue];

transform = CGAffineTransformMakeScale(0.1,0.21);

firstPieceView.transform = transform;

[UIView commitAnimations];

代码循环添加按钮，其他空间也可以用类似方法添加

- (void)viewDidLoad {

[super viewDidLoad];

for(int i = 0; i < 5; i++){

CGRect frame;

Btn[i] = [[UIButton buttonWithType:UIButtonTypeCustom] retain];

[Btn[i] setImage:[UIImage imageNamed:@"Button.png"] forState:UIControlStateNormal];//设置按钮图片

frame.size.width = 55;//设置按钮坐标及大小

frame.size.height = 84;

frame.origin.x = (i%5)*57+5;

frame.origin.y = 10;

[Btn[i] setFrame:frame];

[Btn[i] setBackgroundColor:[UIColor clearColor]];

[Btn[i] addTarget:self action:@selector(btnPressed:) forControlEvents:UIControlEventTouchUpInside];

[self.view addSubview:Btn[i]];

[Btn[i] release];

}

//响应按钮事件

-(void)btnPressed:(id)sender{

for(int i = 0; i < 5;i++){

if([sender isEqual:Btn[i]]){
