iPhone设置视图背景图片的方法

方法一，使用一个UIImageView实例做子视图，并且放最后面

- (void)setBackgroundImage {  
    NSLog(@"setting bg image");  
    UIImageView *customBackground = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"background.jpg"]];  
    self.background = customBackground;  
    [customBackground release];  
      
    [self addSubview:background];  
    NSLog(@"Added background subview %@", background);  
    [self sendSubviewToBack:background];  
}  

 

方法二，Cook Book中提到的方法

- (void)loadView {  
      
    UIImageView *contentView = [[UIImageView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];  
    [contentView setImage:[UIImage imageNamed:@"Default.png"]];  
    [contentView setUserInteractionEnabled:YES];  
    self.view = contentView;  
    [contentView release];  
}  

 

方法三，lvyile网友用的一个小技巧，uiView是UIView的实例，而不是UIImageView

uiView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"Default.png"]];
