可能重复:
UISegmentedControl选择的段颜色
UISegmentcontrol外观导致问题

您好我想将默认的UISegmentControl字体更改为自定义字体,并将选定的段颜色更改为另一种颜色而不是更暗的颜色.

谢谢

由此

我想知道如何将UISearchBar从默认的圆形曲线更改为矩形.

我想测量周围的音量,不太确定我做的是否正确.

我想创建一个范围为0(安静)到120(非常嘈杂)的VU表.

我获得了峰值和平均功率,但在正常安静的环境中非常高.请给我一些指针.

我需要一些帮助.我想通过Bump将Jpg或PNG图像从一个iPhone转移到另一个iPhone.我遇到了成功和失败,根本没有发送图像.

下面是一个NSObject文件,当用户从UIimagepicker中选择图像时将调用该文件.

请帮我看看代码并给我任何评论或观点.

谢谢,感谢您的帮助.

一旦你点击搜索栏,任何人都知道如何调整暗淡的黑色大小？

我点击时有问题取消了tableview将消耗然后动画消失.

我用它来调整我的结果tableview.

-(void)searchDisplayController:(UISearchDisplayController *)controller didShowSearchResultsTableView:(UITableView *)tableView {
   tableView.frame =fTableView.frame;//CGRectMake(26, 100, 280, 310); //fTableView.frame;
    tableView.backgroundColor = [UIColor colorWithRed:243.0/255.0 green:236.0/255.0 blue:212.0/255.0 alpha:1];   
}

单击搜索栏时,灰色叠加层已满,而不是我定义的大小.

单击取消按钮时,视图将重新开始.

我正在运行我的应用程序正常运行,直到我从后台恢复或没有位置服务,应用程序将崩溃.

崩溃日志显示异常类型:EXC_CRASH(SIGTRAP)

有谁知道如何调试它？

我需要一些帮助,我需要知道如何创建从数组中检索的字符串数组.我正在使用powerplot图表,它只接受浮点数或字符串数​​组.

我需要动态地创建这样的东西.

的NSString*sourceData [7] = {@ "2",@ "1",@ "4",@ "8",@ "14",@ "15",@ "10"};

下面是我的代码,以找出字符串中的数字.

NSInteger drunked = [appDelegate.drinksOnDayArray count];
NSMutableArray * dayArray = [[NSMutableArray alloc] init];
NSMutableArray * sdArray = [[NSMutableArray alloc] init];
//float *sdArray[7];


for (int i=0; i<drunked; i++) {
    DayOfDrinks *drinksOnDay = [appDelegate.drinksOnDayArray objectAtIndex:i];
    NSString * dayString= [NSDate stringForDisplayFromDateForChart:drinksOnDay.dateConsumed];
    [dayArray addObject:dayString];
    NSLog(@"%@",[dayArray objectAtIndex:i]);

    drinksOnDay.isDetailViewHydrated = NO;
    [drinksOnDay hydrateDetailViewData];

    NSString * sdString= [NSString stringWithFormat:@"%@", drinksOnDay.standardDrinks];
    [sdArray addObject:sdString];

    NSString *tempstring;
    NSLog(@"%@",[sdArray objectAtIndex:i]);

}

谢谢您的帮助 :)

我想知道这个应用程序是如何在UIKit中叠加uiimage和摇摆不定的.

我正在关注这个xcode:使用带有NSTimers的UIImageView子类 使图像随机下降,但是如何捕获它并将UIImage堆叠在一起？

谢谢你的回复...编辑:为了清楚

https://www.youtube.com/watch?v=2dpZCoi4xFk 40秒后将展示它如何叠加在一起并与加速度计一起摆动

这将模拟UIIimageView的删除

- (void)viewDidLoad {
    [super viewDidLoad];

    // set the background color to something COLD
    self.view.backgroundColor = [UIColor colorWithRed:0.0 green:0.5 blue:1.0 alpha:1.0];

    // load our ph image we will use the same image over and over
    phImage = [UIImage imageNamed:@"placeholder.png"];

    // start a timet that will fire 1 times per second
    [NSTimer scheduledTimerWithTimeInterval:(1) target:self selector:@selector(onTimer) userInfo:nil repeats:YES];
}

// Timer event is called whenever the timer fires

这可能在某处得到回答，但我似乎无法找到答案。

我有各种进口

import KeychainAccess
import Alamofire
import SwiftyJSON
import ...
import ...
import ...

我真的可以将它们全部添加到一个 swift 文件中import HeaderHelper吗？我试图像 ObjC 一样导入但得到了No such module 'HeaderHelper'

任何一点将不胜感激。
