1:导航条返回键带的title太讨厌了,怎么让它消失!
[[UIBarButtonItem appearance] setBackButtonTitlePositionAdjustment:UIOffsetMake(0, -60) forBarMetrics:UIBarMetricsDefault];
2:怎么像safari一样滑动的时候隐藏navigationbar?
navigationController.hidesBarsOnSwipe = Yes
3:怎么播放GIF的时候这么卡,有没有好点的库?
FlipBoard出品的太适合你了:https://github.com/Flipboard/FLAnimatedImage
4:怎么把tableview里cell的小对勾的颜色改成别的颜色?
_mTableView.tintColor = [UIColor redColor];
5:本来我的statusbar是lightcontent的,结果用UIImagePickerController会导致我的statusbar的样式变成黑色,怎么办?
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
}
6:怎么把我的navigationbar弄成透明的而不是带模糊的效果?
[self.navigationBar setBackgroundImage:[UIImage new]
forBarMetrics:UIBarMetricsDefault];
self.navigationBar.shadowImage = [UIImage new];
self.navigationBar.translucent = YES;
7:怎么改变uitextfield placeholder的颜色和位置?
继承uitextfield,重写这个方法
- (void) drawPlaceholderInRect:(CGRect)rect {
[[UIColor blueColor] setFill];
[self.placeholder drawInRect:rect withFont:self.font lineBreakMode:UILineBreakModeTailTruncation alignment:self.textAlignment];
}
8:tableviewCell 只显示高亮状态 不设置选中状态,只要重写
- (void)setSelected:(BOOL)selected animated:(BOOL)animated{
}
9:当设置navigationBar的背景图片时移除黑线的方法,该方法会使translucent属性失效
-(void)useShadowImageRemoveBlackLine
{
//通过设置shadowImage移除黑线
[self.navigationController.navigationBar setShadowImage:[UIImage new]];
}
