问题描述
我的应用程序不断出现语义错误并且一直冻结/崩溃。所有内容似乎都很好地连接在一起并且启动没有问题。 TextFields运行正常,但是一旦我点击其他任何内容它就会失败并强行退出。有什么建议?
My app keeps coming up with a "Semantic Error" and keeps freezing/crashing.Everything seems to be stringed together fine and it launches without problem. TextFields work fine but as soon as I click anything else it fails and forces out. Any recommendations?

@implementation ViewController
//This is where I keep getting the Semantic Error "Incomplete Implementation"
@synthesize buytext1;

- (IBAction)backgroundTouched:(id)sender {

- (IBAction)textFieldReturn:(id)sender {

int VarBuy1 = 0;
int VarSell1 = 0;

int VarPercentage1 =0;
int VarRoyalty = 0;
int VarBuy2 = 0;
int VarSell2 = 0;
int VarProfit2 =0;
int VarPercentage2 =0;
-(IBAction)Button{
VarBuy1 = ([buy1.text intValue]);
VarSell1 = ([sell1.text intValue]);
VarProfit1 = (VarSell1 - (VarSell1 * (VarRoyalty / 100)) - VarBuy1);
VarPercentage1 = (VarProfit1 / VarSell1);
VarSell2 = (VarBuy2 / ((100 - VarRoyalty) / 100 - VarPercentage2));
VarProfit2 = (VarSell2 - (VarSell2 * VarRoyalty) - VarBuy2);
profit1.text = [[NSNumber numberWithInt:VarProfit1] stringValue];
percentage1.text = [[NSNumber numberWithInt:VarPercentage1] stringValue];
sell2.text = [[NSNumber numberWithInt:VarSell2] stringValue];
profit2.text = [[NSNumber numberWithInt:VarProfit2] stringValue];
}
@end
推荐答案
在.h
- (IBAction)textfieldReturn:(id)sender;
在.m
- (IBAction)textFieldReturn:(id)sender
小心字母大小写。字段和字段。
Be careful about letter cases. field and Field.
没有(id)发件人的IBAction听起来不太好。
And an IBAction without (id)sender doesn't sound good.
