UIToolBar 三种办法
方法一
[[UIDevice currentDevice] systemVersion];
if ([[[UIDevice currentDevice] systemVersion] floatValue] > 4.9) {
//iOS 5
UIImage *toolBarIMG = [UIImage imageNamed: @"toolBar_brown.png"];
if ([toolBar respondsToSelector:@selector(setBackgroundImage:forToolbarPosition:barMetrics:)]) {
[toolBar setBackgroundImage:toolBarIMG forToolbarPosition:0 barMetrics:0];
}
} else {
//iOS 4
[toolBar insertSubview:[[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"toolBar_brown.png"]] autorelease] atIndex:0];
}
方法二
// MyToolBar.h
@interface MyToolBar : UIToolbar {
}
@end
// MyToolBar.m
#import "MyToolBar.h"
@implementation MyToolBar
- (void)drawRect:(CGRect)rect {
CGContextRef c = UIGraphicsGetCurrentContext();
UIImage *image = [UIImage imageNamed:@"fish.png"];
CGContextDrawImage(c, rect, image.CGImage);
}
@end
方法三
{
UIImage *img = [[[UIImage alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"ToolbarBk" ofType:@"png"]] autorelease];
[img drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
}
UINavigationBar
在APPDelegate添加
- (void)drawRect:(CGRect)rect {
UIImage *img = [UIImage imageNamed:@"navbar.png"];
[img drawInRect:rect];
}
@end
if ([self.navigationController.navigationBar respondsToSelector:@selector( setBackgroundImage:forBarMetrics:)]){
}
