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

Objective-c代码
 1 - (void)setBackgroundImage {   
 2     NSLog(@"setting bg image");   
 3     UIImageView *customBackground = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"background.jpg"]];   
 4     self.background = customBackground;   
 5     [customBackground release];   
 6        
 7     [self addSubview:background];   
 8     NSLog(@"Added background subview %@", background);   
 9     [self sendSubviewToBack:background];   
10 }  

方法二,Cook Book中提到的方法

Objective-c代码
1 - (void)loadView {   
2        
3     UIImageView *contentView = [[UIImageView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];   
4     [contentView setImage:[UIImage imageNamed:@"Default.png"]];   
5     [contentView setUserInteractionEnabled:YES];   
6     self.view = contentView;   
7     [contentView release];   
8 }  

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

Objective-c代码
1 uiView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"Default.png"]];
