第一种方法:
-(void)setRefreshWindow{
CGRect frame = CGRectMake(0.0, 0.0, 320.0, 20.0);
statusbarWindow = [[UIWindow alloc] initWithFrame:frame];
[statusbarWindow setBackgroundColor:[UIColor clearColor]];
[statusbarWindow setWindowLevel:UIWindowLevelStatusBar+1.0f];
// 添加自定义子视图
UIImageView *customView = [[UIImageView alloc] initWithFrame:CGRectMake(100, 0, 120, 18)];
customView.image=[UIImage imageNamed:@"数据刷新栏.png"];
// UILabel *label=[[UILabel alloc] initWithFrame:CGRectMake(100, 0, 100, 20)];
// // label.backgroundColor=[UIColor clearColor];
// label.text=@"数据正在刷新";
// [customView addSubview:label];
[statusbarWindow addSubview:customView];
[statusbarWindow makeKeyAndVisible];
}
第二种方法:
如果需要在状态栏显示自定义的消息时,就需要自定义状态栏。
代码如下:
XYCustomStatusBar.h
01 |
#import
<UIKit/UIKit.h> |
03 |
@interface
XYCustomStatusBar : UIWindow{ |
05 |
UILabel
*_messageLabel; |
08 |
-
( void )showStatusMessage:(NSString
*)message; |
XYCustomStatusBar.m
01 |
#import
"XYCustomStatusBar.h" |
03 |
@implementation
XYCustomStatusBar |
07 |
[_messageLabel
release], _messageLabel = nil; |
13 |
self.frame
= [UIApplication sharedApplication].statusBarFrame; |
14 |
self.backgroundColor
= [UIColor blackColor]; |
15 |
self.windowLevel
= UIWindowLevelStatusBar + 1.0f; |
17 |
_messageLabel
= [[UILabel alloc] initWithFrame:self.bounds]; |
18 |
[_messageLabel
setTextColor:[UIColor whiteColor]]; |
19 |
[_messageLabel
setTextAlignment:NSTextAlignmentRight]; |
20 |
[_messageLabel
setBackgroundColor:[UIColor clearColor]]; |
21 |
[self
addSubview:_messageLabel]; |
27 |
-
( void )showStatusMessage:(NSString
*)message{ |
30 |
_messageLabel.text
= @ "" ; |
32 |
CGSize
totalSize = self.frame.size; |
33 |
self.frame
= (CGRect){ self.frame.origin, 0, totalSize.height }; |
35 |
[UIView
animateWithDuration:0.5 animations:^{ |
36 |
self.frame
= (CGRect){self.frame.origin, totalSize }; |
37 |
}
completion:^( BOOL finished){ |
38 |
_messageLabel.text
= message; |
47 |
[UIView
animateWithDuration:0.5f animations:^{ |
49 |
}
completion:^( BOOL finished){ |
50 |
_messageLabel.text
= @ "" ; |
为了让自定义的状态栏可以让用户看到,设置了它的windowlevel,在ios中,windowlevel属性决定了UIWindow的显示层次,默认的windowlevel为UIWindowLevelNormal,即0.0 。为了能覆盖默认的状态栏,将windowlevel设置高点。其他代码基本上都不解释什么,如果要特殊效果,可以自己添加。
