在UITextField对象内部显示进度条
|
如何在ѭ0内绘制进度条？到目前为止，我已经测试了两种方法。
1.添加一个“ 1”对象作为“ 0”对象的子视图。
UIProgressView* progressView = [[UIProgressView alloc] init];
[aUITextField addSubview:progressView];
progressView.progress = 0.5;
[progressView release];
UITextfield
drawRect:
- (id)initWithFrame:(CGRect)frame {
if ((self = [super initWithFrame:frame])) {
// Initialization code
[self setBackgroundColor:[UIColor clearColor]];
}
return self;
}
- (void)drawRect:(CGRect)rect {
// Drawing code
[[UIColor orangeColor] setFill];
[[UIBezierPath bezierPathWithOvalInRect:rect] fill];
}

@interface ProgressField : UITextField { } @property (nonatomic, assign) CGFloat progress; @property (nonatomic, retain) UIColor * progressColor; @end@implementation ProgressField @synthesize progress; @synthesize progressColor; - (void)setProgress:(CGFloat)aProgress { if ( aProgress < 0.0 || aProgress > 1.0 ) { return; } progress = aProgress; CGRect progressRect = CGRectZero; CGSize progressSize = CGSizeMake(progress * CGRectGetWidth(self.bounds), CGRectGetHeight(self.bounds)); progressRect.size = progressSize; // Create the background image UIGraphicsBeginImageContext(self.bounds.size); CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSetFillColorWithColor(context, [UIColor clearColor].CGColor); CGContextFillRect(context, self.bounds); CGContextSetFillColorWithColor(context, [self progressColor].CGColor); CGContextFillRect(context, progressRect); UIImage * image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); [super setBackground:image]; } - (void)setBackground:(UIImage *)background { // NO-OP } - (UIImage *)background { return nil; } - (id)initWithFrame:(CGRect)frame { if ((self = [super initWithFrame:frame])) { [self setBorderStyle:UITextBorderStyleBezel]; } return self; }设置为的。响摔衅幸
设置进度视图的框架。碧肮械淌设
