试试我的自定义编码：您可以根据需要更改图像。
.h 文件
//ProgressBar
NSTimer *splashtimer;
UIImage *ProgressBarBackgroundImage;
UIImageView *ProgressBarLeft;
UIImageView *ProgressBarRight;
UIImageView *ProgressBarMiddle;
UIImageView *LoadingBackground;
NSInteger totalSizeOfProgressBarAnimation;
NSInteger totalCountOfProgressBarAnimation;
NSInteger NoOfPercentage;
NSInteger startingvalue;
int progressValue;
//ProgressBar
@property (nonatomic,retain) UIImageView *ProgressBarLeft;
@property (nonatomic,retain) UIImageView *ProgressBarRight;
@property (nonatomic,retain) UIImageView *ProgressBarMiddle;
@property (nonatomic,retain) UIImageView *LoadingBackground;
- (void) ProgressBarSizeCheck:(NSInteger)starting:(NSInteger)ending;
.m 文件
@synthesize ProgressBarLeft,ProgressBarRight,ProgressBarMiddle,LoadingBackground;
- (void)viewDidLoad {
[super viewDidLoad]
splashtimer = [NSTimer scheduledTimerWithTimeInterval: 0.75 target: self selector: @selector(startMoveProgress) userInfo: nil repeats: NO];
ProgressBarLeft = [[UIImageView alloc] init];
ProgressBarMiddle = [[UIImageView alloc] init];
ProgressBarRight = [[UIImageView alloc] init];
LoadingBackground = [[UIImageView alloc] init];
ProgressBarBackgroundImage = [UIImage imageNamed: @"loaderbg.png"];
[self.view addSubview: LoadingBackground];
}
语用标记 -
杂注标记进度条方法
-(void)ProgressBarSizeCheck:(NSInteger)starting:(NSInteger)ending {
startingvalue = starting;
endingValue = ending;
NoOfPercentage = ending - starting;
if (startingvalue==0) {
//ProgressBarLeft Image
ProgressBarLeft.frame = CGRectMake(23,410,10,20);
UIImage *ProgressBarImage = [UIImage imageNamed: @"loaderleftpart.png"];
ProgressBarLeft.image = ProgressBarImage;
[self.view addSubview: ProgressBarLeft];
//LeftImageOver
//ProgressBarMiddleImage
ProgressBarMiddle.frame = CGRectMake(33,410,0,20);
UIImage *ProgressBarImageMiddle = [UIImage imageNamed: @"loadercenterpart.png"];
ProgressBarMiddle.image = ProgressBarImageMiddle;
[self.view addSubview: ProgressBarMiddle];
//MiddleImageOver
//ProgressBarRightImage
ProgressBarRight.frame = CGRectMake(33,410,10,20);
UIImage *ProgressBarImageRight = [UIImage imageNamed: @"loaderrightpart.png"];
ProgressBarRight.image = ProgressBarImageRight;
[self.view addSubview: ProgressBarRight];
//RightImageOver
totalSizeOfProgressBarAnimation = 276 * NoOfPercentage / 100;
totalSizeOfProgressBarAnimation=totalSizeOfProgressBarAnimation-20;
int Duration=NoOfPercentage/10;
[self moveDown:Duration:totalSizeOfProgressBarAnimation];
}
else {
totalSizeOfProgressBarAnimation = 276 * startingvalue / 100;
totalSizeOfProgressBarAnimation=totalSizeOfProgressBarAnimation-20;
//ProgressBarLeftImage
ProgressBarLeft.frame = CGRectMake(23,410,10,20);
UIImage *ProgressBarImage = [UIImage imageNamed: @"loaderleftpart.png"];
ProgressBarLeft.image = ProgressBarImage;
[self.view addSubview: ProgressBarLeft];
//LeftImageOver
//ProgressbarMiddleImage
ProgressBarMiddle.frame = CGRectMake(33,410,totalSizeOfProgressBarAnimation,20);
UIImage *ProgressBarImageMiddle = [UIImage imageNamed: @"loadercenterpart.png"];
ProgressBarMiddle.image = ProgressBarImageMiddle;
[self.view addSubview: ProgressBarMiddle];
//MiddleImageOver
//ProgressBarRightImage
ProgressBarRight.frame = CGRectMake(33+totalSizeOfProgressBarAnimation,410,10,20);
UIImage *ProgressBarImageRight = [UIImage imageNamed: @"loaderrightpart.png"];
ProgressBarRight.image = ProgressBarImageRight;
[self.view addSubview: ProgressBarRight];
//RightImageOver
totalSizeOfProgressBarAnimation = 276 * NoOfPercentage / 100;
int Duration=NoOfPercentage/10;
[self moveDown:Duration:totalSizeOfProgressBarAnimation];
}
}
-(void)moveDown:(NSInteger)animationDuration:(NSInteger)size {
CGRect startFrame = [ProgressBarMiddle frame];
[UIView beginAnimations:@"move10" context:NULL];
[UIView setAnimationDuration:animationDuration];
[ProgressBarMiddle setFrame:CGRectMake(startFrame.origin.x, 410, startFrame.size.width+size, startFrame.size.height)];
[ProgressBarRight setFrame:CGRectMake(33+(startFrame.size.width+size),410,10,20)];
[UIView setAnimationDelegate:self];
[UIView setAnimationCurve: UIViewAnimationCurveEaseOut];
[UIView commitAnimations];
splashtimer = [NSTimer scheduledTimerWithTimeInterval: animationDuration target: self selector: @selector(pushTabControl) userInfo: nil repeats: NO];
}
-(void)pushTabControl {
[self.navigationController pushViewController: tabObj animated:YES];
}
-(void) startMoveProgress {
LoadingBackground.frame = CGRectMake(22,410,276,22);
UIImage *ProgressBarBackgroundImage = [UIImage imageNamed: @"loaderbg.png"];
[LoadingBackground setUserInteractionEnabled: YES];
LoadingBackground.image = ProgressBarBackgroundImage;
[self ProgressBarSizeCheck:0:100];
}
//看图片
1)loaderbg.png
2）装载机中心部分
3)loaderrightpart
4）loderleft部分
