1.修改textfield的顏色及位置

可以繼承textfield類

重寫它的方法；

-(void)drawPlaceholderInRect:(CGRect)rect

{

[[UIColor purpleColor]setFill];

[self.placeholder drawInRect:rect withFont:self.font lineBreakMode:UILineBreakModeTailTruncation alignment:self.textAlignment];

}

2.設(shè)置導(dǎo)航條透明?

[self.navigationController.navigationBar setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];

self.navigationController.navigationBar.shadowImage = [UIImage new];

self.navigationController.navigationBar.translucent = YES;

3.當(dāng)自定義導(dǎo)航條左側(cè)的item ?iOS 自帶的側(cè)滑就會(huì)消失 可以這樣來實(shí)現(xiàn)側(cè)滑

self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc]initWithImage:nil style:UIBarButtonItemStylePlain target:self action:@selector(act)];? ? self.navigationController.interactivePopGestureRecognizer.delegate = (id<UIGestureRecognizerDelegate>)self;

4.監(jiān)控鍵盤的事件；IQKeyboardManager ?三方庫

滑動(dòng)，點(diǎn)擊 隱藏導(dǎo)航欄（iOS8之后）

self.navigationController.hidesBarsOnSwipe = YES;

self.navigationController.hidesBarsOnTap = YES;

5.xib中設(shè)置邊框

@interface CALayer (XibConfiguration)

// layer.cornerRadius

// layer.borderWidth

// layer.borderUIColor? 邊框顏色屬性用borderUIColor

@property(nonatomic, assign) UIColor *borderUIColor;

-(void)setBorderUIColor:(UIColor*)color

{self.borderColor = color.CGColor;}

-(UIColor*)borderUIColor

{return [UIColor colorWithCGColor:self.borderColor];}
