按下按钮时,我必须按下新的segue.但我也有一个附加的动作,需要在推动segue之前触发.
你能告诉我如何将它们彼此分开吗?任何帮助,将不胜感激.
在iPhone 5之前,我可以将admob横幅放在屏幕的底部(正好在标签栏上方).但由于iPhone 5的屏幕尺寸,现在一切都受到了干扰.我甚至试图通过Autolayout来做(它没有用).我如何为两种屏幕尺寸做到这一点?
这是我的代码 -
-(void) viewDidLoad {
[super viewDidLoad];
adMob = [[GADBannerView alloc] initWithFrame:CGRectMake(0.0,
367.0 -
GAD_SIZE_320x50.height,
GAD_SIZE_320x50.width,
GAD_SIZE_320x50.height)];
adMob.translatesAutoresizingMaskIntoConstraints=NO;
// Specify the ad's "unit identifier." This is your AdMob Publisher ID.
adMob.adUnitID = @"XXXXXXXX";
// Let the runtime know which UIViewController to restore after taking
// the user wherever the ad goes and add it to the view hierarchy.
adMob.rootViewController = self;
GADRequest *request = [GADRequest request];
request.testing=YES;
[self.view addSubview:adMob];
// Initiate a generic request to load it …Run Code Online (Sandbox Code Playgroud) 我正在AFNetworking用来获取单元格中的JSON数据UITableView.我已经将数组声明为NSMutableArray,但是-[__NSCFArray removeObjectAtIndex:]: mutating method sent to immutable object当我尝试重新排序单元格时,我仍然会收到错误并且应用程序崩溃了.
这是我用于重新排序的逻辑 -
-(void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath
toIndexPath:(NSIndexPath *)toIndexPath {
NSString *item = [self.jobsArrayFromAFNetworking objectAtIndex:fromIndexPath.row];
[self.jobsArrayFromAFNetworking removeObject:item];
[self.jobsArrayFromAFNetworking insertObject:item atIndex:toIndexPath.row];
}
